Buick Encore Tire Size: Complete Guide by Year and Trim

Finding the correct Buick Encore tire size sounds easy until we start shopping. Then the questions arrive all at once. Is the Encore the same as the Encore GX? Does every model use 18-inch tires? Can we install a wider tire? What do all those numbers on the sidewall actually mean?

The good news is that the original Buick Encore kept things relatively simple. Most versions sold in North America use 215/55R18 tires, although some early models were available with smaller 16-inch wheels. The Encore GX is a different vehicle and usually uses wider tires, commonly 225/55R18, with other sizes offered on certain trims and model years.

That small difference matters. A tire that looks close enough may still affect speedometer accuracy, ride quality, steering response, fuel economy, clearance, and safety systems. Tires are the shoes of the vehicle, and wearing the wrong pair can make every journey feel slightly off.

In this guide, we will explain Buick Encore tire sizes by year, decode the numbers printed on the sidewall, discuss replacement options, and help you choose tires that match your climate, driving habits, and budget.

What Is the Standard Buick Encore Tire Size?

For most Buick Encore models from the 2013 through 2022 model years, the most common original-equipment tire size is:

215/55R18

This size appears across many trims, including Base, Convenience, Preferred, Sport Touring, Essence, and Premium versions. Tire-size databases list 215/55R18 as the standard fitment for most Encore models from 2014 onward. The 2013 model year is slightly different because some entry-level configurations were also offered with 205/70R16 tires.

The size fitted to an individual vehicle may still vary because of:

• Model year
• Trim level
• Factory wheel package
• Country or regional specification
• Previous wheel modifications
• Replacement wheels installed by an earlier owner

That is why we should never order tires using the vehicle name alone. The safest approach is to check the tire-information label on the driver-side door jamb.

Buick Encore Tire Size Chart by Model Year

The following chart covers the most common North American factory sizes for the original Buick Encore.

Model Year	Common Tire Size	Common Wheel Size
2013	205/70R16 or 215/55R18	16 or 18 inches
2014	215/55R18	18 inches
2015	215/55R18	18 inches
2016	215/55R18	18 inches
2017	215/55R18	18 inches
2018	215/55R18	18 inches
2019	215/55R18	18 inches
2020	215/55R18	18 inches
2021	215/55R18	18 inches
2022	215/55R18	18 inches

These are common factory fitments rather than a substitute for checking the vehicle itself. Buick directs owners to its model-specific manuals and guides for vehicle information, while the certification label and tire placard remain the most reliable references for a particular Encore.

2013 Buick Encore Tire Size

The 2013 Buick Encore deserves extra attention because it may use one of two sizes:

• 205/70R16
• 215/55R18

The 16-inch setup offers a taller sidewall. That extra rubber can soften impacts from potholes, expansion joints, and rough city streets. It may not look as sporty, but it can feel more forgiving.

The 18-inch setup uses a lower-profile tire that gives the Encore a sharper appearance and slightly more immediate steering response. However, replacement tires may cost more, and the shorter sidewall provides less protection against severe potholes.

How to Identify the Correct 2013 Size

Look at the existing tire sidewall and compare it with the driver-door placard. Never assume that the tires currently installed are correct, especially on an older used vehicle. Previous owners may have replaced the factory wheels or selected a nonstandard tire size.

2014–2016 Buick Encore Tire Size

Most 2014, 2015, and 2016 Encore trims use:

215/55R18

This includes common Base, Convenience, Premium, and Sport Touring configurations. The consistency makes replacement shopping easier, but we still need to match the original load index and speed rating.

A tire labeled 215/55R18 may be physically the correct size while carrying an unsuitable load rating. The complete sidewall code might look something like:

215/55R18 95H

The final numbers and letter describe load capacity and speed capability. They should meet or exceed Buick’s requirements.

2017–2019 Buick Encore Tire Size

Most Encore models from 2017 through 2019 also use:

215/55R18

That includes several trim names introduced or reorganized during this period, such as Preferred, Preferred II, Essence, Premium, and Sport Touring. Despite the different badges and equipment packages, the standard tire dimensions remained remarkably consistent.

This is helpful for availability. Because 215/55R18 is widely used on compact crossovers, we can usually find plenty of all-season, touring, winter, and performance-oriented options.

2020–2022 Buick Encore Tire Size

The original Encore continued using 215/55R18 on most North American versions through its final model years. Listings for the 2020, 2021, and 2022 Encore identify this as the standard size for Base and Preferred models.

Do not confuse these vehicles with the Encore GX, which was sold alongside the original Encore. Their similar names hide meaningful differences in body structure, engines, wheels, and tire specifications.

Buick Encore vs Encore GX Tire Size

The Buick Encore and Encore GX are not simply two trims of the same crossover. They are separate models.

The original Encore commonly uses:

215/55R18

The Encore GX commonly uses:

225/55R18

The GX tire is 10 millimeters wider. It also has a slightly taller overall diameter because the sidewall height is calculated as a percentage of tire width.

General Motors listed 225/55R18 all-season tires with 18-by-7.5-inch wheels in published specifications for the redesigned 2024 Encore GX.

Some Encore GX trims and packages may use other wheel diameters, so we should confirm the exact size before purchasing. Tire manufacturers such as Michelin also list 225/55R18 as a fitment for certain 2023 Encore GX versions.

Can Encore GX Tires Fit a Regular Encore?

We should not assume they can.

Even when two tire sizes fit 18-inch wheels, the width, overall diameter, wheel width, offset, and available suspension clearance may differ. Installing GX tires on an original Encore could cause:

• Tire rubbing during sharp turns
• Contact with suspension components
• Incorrect speedometer readings
• Reduced fuel economy
• Altered steering feel
• Additional stress on wheel bearings
• Compatibility problems with traction-control systems

A tire shop should verify wheel width, offset, diameter, load rating, and clearance before approving any nonstandard size.

What Does 215/55R18 Mean?

The code looks technical, but it becomes simple when we break it apart.

215: Tire Width

The first number represents the approximate width of the tire in millimeters.

A 215 tire is about 215 millimeters wide from sidewall to sidewall when mounted on an approved wheel width.

A wider tire can provide a larger contact patch, but wider is not automatically better. It may also increase rolling resistance, road noise, weight, and the likelihood of rubbing.

55: Aspect Ratio

The second number is the sidewall height expressed as a percentage of tire width.

For a 215/55R18 tire:

• Width: 215 millimeters
• Sidewall ratio: 55%
• Approximate sidewall height: 118.25 millimeters

A lower aspect ratio usually means a shorter, stiffer sidewall. That can improve steering response, but it may produce a firmer ride.

R: Radial Construction

The letter R means radial construction. Nearly every modern passenger-vehicle tire uses this design.

The internal cords run radially across the tire, helping provide predictable handling, durability, and heat control.

18: Wheel Diameter

The final number indicates that the tire fits an 18-inch wheel.

A 215/55R18 tire cannot be mounted on a 17-inch or 19-inch wheel. The wheel diameter and tire diameter must match exactly.

Where to Find the Correct Buick Encore Tire Size

We have several places to verify the proper size.

Driver-Side Door-Jamb Label

Open the driver’s door and inspect the label attached to the door frame or pillar. It normally lists:

• Original front tire size
• Original rear tire size
• Recommended cold tire pressure
• Spare-tire information
• Vehicle load limits

This label is more dependable than a general website because it reflects the vehicle’s original factory configuration.

Current Tire Sidewall

The tire size is printed in large characters on the sidewall. However, we should compare it with the door placard before trusting it.

A previous owner may have changed the wheel-and-tire package.

Owner’s Manual

The owner’s manual explains tire care, inflation, rotation, replacement, loading, and safety information. Buick and GM Canada provide online manual-selection pages organized by year, make, and model.

Vehicle Identification Number

A Buick dealer or professional tire retailer can use the VIN to identify the vehicle’s original equipment. This is useful when the door label is damaged, missing, or difficult to read.

Buick Encore Tire Pressure and Tire Size

Tire size and tire pressure work together, but they are not the same thing.

The correct pressure is not simply whatever appears on the tire sidewall. The sidewall usually shows the maximum pressure associated with the tire’s load capacity, not the recommended everyday inflation pressure for the vehicle.

We should follow the cold-pressure figure on the driver-door placard.

“Cold” means the vehicle has been parked for several hours or driven only a short distance at low speed. As tires warm up, pressure naturally rises.

Why Proper Inflation Matters

Incorrect pressure can lead to:

• Uneven tread wear
• Longer braking distances
• Reduced cornering grip
• Poor fuel economy
• Excessive heat buildup
• Harsher ride quality
• Increased risk of tire damage

Underinflated tires flex like soft balloons, generating heat and wearing their outer shoulders. Overinflated tires can make the Encore feel nervous over rough pavement and may wear more heavily through the center of the tread.

Can We Install a Different Tire Size?

Sometimes—but the replacement needs to stay close to the original overall diameter and remain compatible with the wheel and vehicle.

A different tire size may be considered for:

• Winter wheels
• Improved ride comfort
• Lower replacement cost
• Aesthetic customization
• Performance preferences
• Greater availability in a particular region

However, changing sizes without calculating the consequences is like altering one ingredient in a cake and expecting the same result. Every dimension affects something else.

The Three-Percent Rule

A common guideline is to keep the new tire’s overall diameter within approximately 3% of the original. Smaller differences are generally preferable.

A large diameter change can affect:

• Speedometer accuracy
• Odometer readings
• Transmission behavior
• Anti-lock braking
• Stability control
• Fender clearance
• Ground clearance

The 3% guideline is not a guarantee of safe fitment. Wheel width, offset, suspension clearance, and load capacity also matter.

Possible Alternative Sizes for the Buick Encore

Some drivers consider smaller wheels with taller-sidewall tires, particularly for winter use. A 16- or 17-inch setup may provide improved pothole protection and a softer ride.

Still, the exact alternative depends on the model year, brake clearance, wheel dimensions, and local regulations. We should not recommend one universal alternative for every Encore.

A professional installer should verify:

1. Wheel bolt pattern
2. Center-bore size
3. Wheel offset
4. Wheel width
5. Brake-caliper clearance
6. Tire load index
7. Tire speed rating
8. Overall diameter
9. Fender and suspension clearance
10. Tire-pressure monitoring compatibility

Why Downsizing Can Make Sense

A smaller wheel paired with a taller tire sidewall can offer:

• Better impact absorption
• Lower risk of wheel damage
• Less expensive winter tires
• Improved comfort on broken pavement
• Better performance in deep snow when a narrower tire is used correctly

The trade-off may include softer steering response and a less aggressive appearance.

Best Tire Type for a Buick Encore

The correct size is only half the decision. We also need the right tire category.

All-Season Tires

All-season tires are the default choice for many Encore owners. They balance dry-road grip, wet traction, tread life, comfort, and mild cold-weather capability.

They make sense for drivers who experience moderate temperatures and limited snowfall.

Their strengths include:

• Long tread life
• Quiet highway performance
• Good everyday comfort
• Broad availability
• Competitive pricing

However, ordinary all-season tires are not true winter tires. When temperatures fall sharply, their rubber compounds can become firmer and less effective.

All-Weather Tires

All-weather tires bridge the gap between conventional all-season and winter tires. Many carry the three-peak mountain snowflake symbol, indicating that they meet a defined snow-traction standard.

They suit drivers who want one set year-round but still face meaningful winter conditions.

Compared with traditional all-season tires, they may have:

• Better cold-weather grip
• Stronger snow traction
• More aggressive tread patterns
• Slightly greater road noise
• Potentially shorter tread life

Winter Tires

Dedicated winter tires are the safest choice for regular driving in snow, ice, slush, and freezing temperatures.

Their softer compounds remain flexible in the cold, while specialized tread designs create thousands of biting edges.

Winter tires can improve:

• Acceleration on snow
• Emergency braking
• Cornering stability
• Control on icy roads
• Confidence during freezing weather

All-wheel drive can help an Encore accelerate, but it cannot manufacture braking grip. Winter tires support acceleration, turning, and stopping.

Summer Tires

Summer tires prioritize warm-weather grip and steering response. They can perform well in dry and wet conditions when temperatures remain warm.

They are uncommon on the Encore because most owners value comfort, versatility, and tread life more than maximum cornering performance.

Summer tires should not be used in snow or near-freezing temperatures unless the manufacturer specifically permits it.

How to Choose the Best Buick Encore Tires

Instead of shopping by brand name alone, we should begin with how the vehicle is used.

For Daily City Driving

Prioritize:

• Quiet operation
• Comfortable ride
• Strong wet braking
• Pothole resistance
• Long tread life

A touring all-season tire usually fits this role well.

For Highway Commuting

Look for:

• Low road noise
• Straight-line stability
• Fuel-efficient construction
• Long treadwear warranty
• Predictable wet-weather behavior

A premium touring tire may cost more initially but can feel smoother and more refined over thousands of miles.

For Snowy Regions

Choose a dedicated winter tire or a capable all-weather model with the three-peak mountain snowflake symbol.

Do not judge winter capability solely by an “M+S” marking. That marking may appear on many all-season tires and does not necessarily indicate the same tested snow performance as the mountain-snowflake symbol.

For Rough Roads

We should value:

• Strong sidewalls
• Impact resistance
• Good ride compliance
• Road-hazard protection
• A reputable installer

Drivers dealing with severe potholes may also explore an approved smaller-wheel setup with more sidewall.

Load Index and Speed Rating Explained

After the tire size, we will usually see a number and letter, such as 95H.

Load Index

The number represents the maximum load that one properly inflated tire can support.

We should choose a replacement with a load index that meets or exceeds the vehicle manufacturer’s requirement.

Using a lower load index may lead to excessive heat, sidewall stress, instability, or premature failure.

Speed Rating

The letter indicates the tire’s certified speed capability under controlled test conditions.

Common passenger-tire ratings include:

• T
• H
• V
• W

The rating does not encourage us to drive at that speed. It also reflects aspects of heat resistance and construction. Replacement tires should normally match or exceed the original rating unless a qualified professional approves an exception, such as certain winter-tire applications.

Should All Four Tires Match?

Ideally, yes.

All four tires should share the same:

• Size
• Model
• Tread pattern
• Load index
• Speed rating
• Construction type
• Similar tread depth

Matching tires help the Encore behave consistently during braking, acceleration, and cornering.

This becomes especially important on all-wheel-drive versions. Large tread-depth differences can create variations in rolling circumference, potentially placing additional strain on drivetrain components.

Replacing Only Two Tires

When only two tires are replaced, many tire professionals recommend installing the new pair on the rear axle.

Why the rear? Deeper rear tread helps reduce the risk of sudden oversteer and loss of stability on wet roads.

Local guidance and vehicle-specific recommendations should always take priority.

Buick Encore Tire Rotation

Regular rotation promotes even wear and can extend tire life.

Front tires often wear faster because they handle steering and a large share of braking force. On front-wheel-drive Encore models, they also transfer engine power to the road.

A common rotation interval is around every 5,000 to 8,000 miles, but the owner’s manual and tire manufacturer should determine the final schedule.

Rotation patterns may vary depending on whether the tires are:

• Directional
• Nondirectional
• Staggered
• Full-size matched
• Temporary-spare equipped

Directional tires generally move front to rear on the same side unless they are removed from the wheels and remounted.

When Should Buick Encore Tires Be Replaced?

Tires should be replaced when they are worn, damaged, aged, or no longer suited to the conditions.

Warning signs include:

• Tread at or below the legal minimum
• Cracks in the sidewall
• Exposed cords
• Bulges or bubbles
• Repeated pressure loss
• Severe vibration
• Uneven wear
• Cuts or punctures near the shoulder
• Noticeable loss of wet or winter traction

Tread Depth Matters Before the Legal Limit

A tire can remain technically legal while delivering noticeably weaker wet-road performance.

As grooves become shallower, the tire has less capacity to channel water away from the contact patch. Hydroplaning resistance declines, especially at highway speeds.

For snow driving, useful tread depth is even more important because the tire needs space to pack, release, and bite into snow.

Tire Age Matters Too

A tire can age even when it still has visible tread. Heat, sunlight, storage conditions, and chemical changes gradually harden the rubber.

The manufacturing date appears in the final four digits of the DOT code. For example:

2325

This means the tire was manufactured during the 23rd week of 2025.

Older tires should be inspected professionally, especially if the vehicle is driven infrequently.

Common Buick Encore Tire Problems

Uneven Inner or Outer-Edge Wear

Possible causes include:

• Incorrect alignment
• Worn suspension components
• Improper inflation
• Frequent aggressive cornering
• Bent wheels

An alignment can adjust suspension angles, but it cannot repair loose or damaged parts. The suspension should be inspected first if unusual wear is severe.

Center Tread Wear

Wear concentrated through the center may suggest overinflation, although tire design, driving conditions, and load also influence wear patterns.

Both Shoulder Edges Wearing

Wear on both outer shoulders can indicate underinflation. The tire bends excessively, forcing the shoulder areas to carry more of the load.

Cupping or Scalloped Wear

Cupping appears as alternating high and low spots around the tread. It may be associated with worn shocks, unbalanced wheels, loose suspension parts, or alignment issues.

It often creates a humming or drumming sound that increases with speed.

Steering-Wheel Vibration

Vibration can result from:

• Wheel imbalance
• Bent wheels
• Tire damage
• Uneven tread wear
• Improper mounting
• Suspension wear
• Road-force variation

A basic balance may solve the problem, but persistent vibration deserves a thorough inspection.

Buick Encore Spare Tire Size

Spare-tire equipment varies by model year, trim, market, and package. Some vehicles may use a temporary compact spare, while others may include an inflator or sealant kit.

A temporary spare is designed for limited speed and distance. It should not be treated as a normal replacement tire.

Before a long journey, check:

• Whether the vehicle has a spare
• The spare’s inflation pressure
• The location of the jack
• The location of the wheel wrench
• Whether the inflator kit has expired
• Instructions in the owner’s manual

A spare hidden beneath the cargo floor is easy to forget until the moment we need it most.

How Much Do Buick Encore Tires Cost?

Pricing varies based on brand, category, warranty, region, season, and retailer.

A budget all-season tire may offer an attractive purchase price, while a premium touring or winter tire may cost substantially more. Installation also adds expenses such as:

• Mounting
• Balancing
• Valve stems
• Tire disposal
• Alignment
• Tire-pressure sensor service
• Road-hazard coverage
• Taxes and environmental fees

We should compare total installed cost rather than the advertised tire price alone.

Are Premium Tires Worth It?

Sometimes.

Premium tires may offer advantages in wet braking, noise control, tread consistency, cold-weather performance, or longevity. Yet a well-reviewed midrange tire can be a smarter purchase for a lightly driven Encore.

The best value is not always the cheapest tire or the most expensive one. It is the tire that performs reliably in the conditions we actually face.

Mistakes to Avoid When Buying Encore Tires

Avoid these common errors:

1. Confusing the Encore with the Encore GX
2. Ordering by wheel diameter alone
3. Ignoring load index
4. Using the tire’s maximum pressure as the normal pressure
5. Installing dramatically different tread depths on an AWD model
6. Choosing tires based only on appearance
7. Buying used tires without checking age and damage
8. Replacing one tire without comparing rolling circumference
9. Ignoring alignment after abnormal wear
10. Assuming every model year has identical equipment

The most expensive mistake is often the one that looked like a bargain at checkout.

A Simple Buick Encore Tire Buying Checklist

Before placing an order, confirm:

• Exact model: Encore or Encore GX
• Model year
• Trim level
• Current wheel diameter
• Door-placard tire size
• Load index
• Speed rating
• Seasonal tire category
• Driving environment
• Installation cost
• Warranty coverage
• Manufacturing date
• Return or fitment policy

This five-minute check can prevent days of frustration.

Final Thoughts on Buick Encore Tire Size

For most original Buick Encore models, the answer is refreshingly straightforward: 215/55R18 is the dominant factory tire size. The main exception is the 2013 Encore, which may also use 205/70R16, depending on its original configuration.

The Encore GX should be treated separately. Many GX models use 225/55R18, including the published 2024 configuration, but sizes can vary with trim and wheel package.

Still, a model-year chart should be our starting point, not the final verdict. The driver-door tire placard, owner’s manual, current wheel specifications, and VIN-based fitment information provide the strongest confirmation.

Once the size is correct, we can focus on what truly shapes the driving experience: wet braking, winter grip, comfort, durability, noise, and price. The right tires will not transform the Encore into a sports car or an off-road truck. They will do something more valuable—they will help it feel stable, predictable, and comfortable every time the road unfolds ahead.

Frequently Asked Questions

1. What tire size does a Buick Encore use?

Most Buick Encore models use 215/55R18 tires. Some 2013 Base models may use 205/70R16 tires. Check the driver-side door placard before ordering replacements.

2. Does the Buick Encore GX use the same tires as the Encore?

Usually not. The original Encore commonly uses 215/55R18, while many Encore GX models use 225/55R18. Other GX sizes may be available depending on trim and model year.

3. Can I put 225-width tires on a Buick Encore?

Not automatically. A wider tire must be compatible with the wheel width, offset, suspension clearance, load requirement, and overall diameter. Have a qualified tire professional verify the fitment.
