The 2015 Chevrolet Trucks Trax arrived as a compact crossover built for city-friendly maneuverability, everyday utility, and a higher seating position than a traditional small car. For many owners, it bridges practical commuter duty with the flexibility expected from a modern Chevrolet utility vehicle. Tire fitment depends on trim, with LS and LT models using 205/70R16 radial tires and LTZ models using 215/55R18 radials. That makes wheel diameter and sub-model identification the first step before comparing replacement options. Once the correct size is confirmed, the real choice becomes selecting the right radial tire for the vehicle’s wheel setup, intended road use, and overall appearance.
Which Tire Size Is Right for The 2015 Chevrolet Trucks Trax
The 2015 Chevrolet Trucks Trax uses two primary tire sizes, and the difference comes down to sub-model and wheel diameter. LS and LT models use a 16-inch setup, while LTZ models use an 18-inch setup, so the first step is confirming the exact trim and the wheels currently on the vehicle before choosing a tire.
205/70R16 is a metric radial size in which 205 refers to section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 16 is the rim diameter in inches. On the 2015 Chevrolet Trucks Trax, this size is used on 16-inch-wheel configurations and suits the modern crossover layout of the LS and LT sub-models. Its profile and diameter are part of the vehicle’s intended fitment package rather than a generic small-SUV size choice. Before replacing it, confirm that the Trax still has the correct 16-inch wheels and has not been changed to another trim’s wheel package.
215/55R18 is a metric radial size that uses a 215-millimeter section width, a 55-series aspect ratio, and an 18-inch rim diameter. This size belongs to the 18-inch-wheel fitment used on the 2015 Chevrolet Trucks Trax LTZ, giving that sub-model a different wheel-and-tire combination from LS and LT versions. It is not simply an alternate profile of the 16-inch setup, because rim diameter changes with it. A buyer considering this size should verify the vehicle’s trim and current wheel package first, especially if the Trax has had wheels swapped at some point.
Sub-model fitment matters on the 2015 Chevrolet Trucks Trax because tire size changes with trim. LS and LT share the same 16-inch radial size, while LTZ moves to a different 18-inch setup, so confirming the exact sub-model prevents ordering the wrong tire.

2015 Chevrolet Trucks Trax LS
The 2015 Chevrolet Trucks Trax LS uses the 205/70R16 radial fitment. Tire selection for this sub-model centers on staying with the correct 16-inch size and confirming that the wheels have not been changed from the original trim-level configuration.
The 2015 Chevrolet Trucks Trax LT also uses the 205/70R16 radial size, matching the LS rather than the LTZ. That keeps replacement straightforward as long as the vehicle still wears the correct 16-inch wheels and has not been converted to a different wheel package.
The 2015 Chevrolet Trucks Trax LTZ uses the 215/55R18 radial fitment instead of the 16-inch size used on LS and LT models. That means tire replacement starts with verifying the 18-inch wheel setup so the lower-profile size is matched to the correct trim and rim diameter.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
Common questions for the 2015 Chevrolet Trucks Trax usually center on the correct tire size by trim, the difference between the 16-inch and 18-inch setups, and what owners should inspect before replacing or driving on tires.
Tire Size & Fitment
What tire size fits a 2015 Chevrolet Trucks Trax?
The 2015 Chevrolet Trucks Trax uses two tire sizes depending on sub-model. LS and LT models use 205/70R16 radial tires, while the LTZ uses 215/55R18 radial tires. Both are modern metric radial fitments, but they are tied to different wheel diameters and should not be treated as one interchangeable size choice.
The most important step is identifying the exact trim and confirming the wheels currently on the vehicle. A Trax with replacement wheels or a trim-level wheel swap may no longer match its original configuration, so checking the tire sidewall and wheel diameter before ordering helps prevent a mismatch in rim size, profile, and overall fitment.
What size rim does a 2015 Chevrolet Trucks Trax use?
A 2015 Chevrolet Trucks Trax uses either a 16-inch or 18-inch rim, depending on sub-model. LS and LT models are fitted with 16-inch rims paired with 205/70R16 tires, while LTZ models use 18-inch rims with 215/55R18 tires. Rim diameter is part of the primary fitment, not just a styling detail.
Checking rim diameter first matters because a 16-inch tire cannot be mounted on an 18-inch wheel, and the reverse is also true. If the Trax has had aftermarket wheels installed, measure or confirm the actual wheel diameter before choosing tires, then verify width and clearance so the replacement matches the vehicle’s current setup.
Do all 2015 Chevrolet Trucks Trax sub-models use the same tire size?
No. The 2015 Chevrolet Trucks Trax LS and LT share the 205/70R16 radial size, but the LTZ uses a different size, 215/55R18. That means fitment is split by trim rather than shared across the full model range, and the difference includes both tire size and wheel diameter.
That distinction matters because tire selection starts with the sub-model, not just the model name. A quick trim check helps narrow the correct size immediately, and it is still wise to confirm the wheels on the vehicle itself in case a previous owner changed them. Matching the tire to the actual wheel package is the safest fitment habit.
Choosing the Right Tire
What should I consider when choosing a 205/70R16 tire for a 2015 Chevrolet Trucks Trax?
For a 2015 Chevrolet Trucks Trax equipped with 205/70R16 tires, the starting point is confirming that the vehicle is an LS or LT model still using its correct 16-inch wheel setup. Since this is a metric radial fitment, the replacement should match the same basic size and construction unless the wheel package has been changed.
Beyond size, compare how the tire will be used day to day. A Trax that sees mostly commuting, wet-weather driving, or longer highway use may call for a different tread emphasis than one used mainly for short local trips. Wheel condition, suspension wear, and alignment should also be checked so a new tire can perform as intended.
What should I consider when choosing a 215/55R18 tire for a 2015 Chevrolet Trucks Trax?
Choosing a 215/55R18 tire for a 2015 Chevrolet Trucks Trax starts with confirming that the vehicle is an LTZ or otherwise equipped with the correct 18-inch wheels. This size uses a lower-profile metric radial format than the 16-inch setup, so matching the rim diameter and intended trim-level package is essential.
A lower-profile tire places more emphasis on using the right wheel and maintaining proper inflation and alignment. Before replacement, inspect the wheels for damage, verify there is no uneven wear pattern from suspension issues, and make sure the vehicle has not been altered in a way that affects clearance around the fenders or steering components.
How do I choose between the available tires for a 2015 Chevrolet Trucks Trax?
The first choice is not between tire styles but between the two correct fitments: 205/70R16 for LS and LT models, or 215/55R18 for LTZ models. Once the correct size is confirmed, the best comparison points are tire category, intended driving use, seasonal priorities, and whether the vehicle remains on its original wheel package.
A practical approach is to match the replacement tire to how the Trax is actually driven. Daily commuting, frequent rain, highway miles, or occasional long-distance use can all influence what type of tread and ride character makes sense. Tire age, alignment condition, and the condition of the existing wheels are worth checking before making the final selection.
Restoration & Appearance
Does correct tire fitment matter for a 2015 Chevrolet Trucks Trax restoration?
Yes. Even though a 2015 Chevrolet Trucks Trax is a modern vehicle compared with older collector cars, correct tire fitment still matters if the goal is to keep the vehicle visually and mechanically close to its intended trim-level presentation. LS and LT models use 205/70R16, while LTZ models use 215/55R18, and that difference shapes the vehicle’s overall stance.
Using the wrong size can change the appearance of the Trax and may also create avoidable fitment issues at the wheel. Owners pursuing a clean, original-style look should start with the proper trim-specific size, then compare wheel finish, tire profile, and overall presentation against vehicle photos, original sales material, or marque-specific reference sources.
How does tire size affect the appearance of a restored 2015 Chevrolet Trucks Trax?
Tire size has a visible effect on how a restored 2015 Chevrolet Trucks Trax sits and how its wheels fill the openings. The 205/70R16 setup used on LS and LT models presents a different wheel-and-sidewall relationship than the 215/55R18 fitment used on LTZ models, even though their overall diameters are very close.
That means appearance is tied not only to tire dimensions but also to having the correct wheel diameter for the trim. A restoration-minded owner should avoid choosing a tire by look alone and instead confirm the intended sub-model presentation first. Keeping the proper size and wheel combination helps the finished vehicle look coherent rather than improvised.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Chevrolet Trucks Trax?
Yes. Modifications can change tire fitment on a 2015 Chevrolet Trucks Trax even when the model name stays the same. Aftermarket wheels, altered wheel width, suspension changes, and lowered or lifted ride height can all affect how a 205/70R16 or 215/55R18 tire sits in the wheel opening and clears nearby components.
That is why replacement should be based on the vehicle’s current setup, not assumptions about stock trim alone. Check the actual wheel diameter and width, then inspect steering and fender clearance at full lock and through suspension movement. A Trax with changed wheels may need more careful measurement before any new tire is selected.
What should I inspect before driving a 2015 Chevrolet Trucks Trax on new tires?
Before driving a 2015 Chevrolet Trucks Trax on new tires, inspect the wheels for bends or damage, confirm that all four tires match the intended size for the trim, and make sure inflation is set correctly for the vehicle’s use. It also helps to look for signs of alignment trouble, such as unusual wear on the previous set.
A road-ready check should also include suspension and steering condition, especially on a vehicle that has seen curb impacts or rough roads. Listen for noises, verify there is no rubbing at parking-lot speeds, and recheck pressure after the first period of use. Those simple steps help the new tires wear evenly and track properly.
How often should tires on a 2015 Chevrolet Trucks Trax be inspected?
Tires on a 2015 Chevrolet Trucks Trax should be inspected regularly rather than only when replacement is due. A quick visual check for cuts, bulges, cracking, embedded debris, and uneven tread wear is a smart habit, and pressure should be monitored consistently because underinflation or overinflation can affect ride, wear, and handling.
More frequent inspection makes sense when the Trax is driven daily, parked outdoors for long periods, or used on rough pavement. It is also worth checking the tires before longer trips and after seasonal temperature swings. Catching slow air loss, edge wear, or aging early can prevent larger problems and protect the vehicle’s overall fitment balance.
