The 2021 Chevrolet Trucks Trax is a compact crossover built for everyday versatility, balancing city-friendly size with the higher seating position and practical utility many drivers want in a modern small SUV. For tire selection, that means fitment is driven less by era-specific vintage sizing and more by trim and wheel package. This Trax uses two primary radial sizes, 205/70R16 and 215/55R18, so the first step is confirming whether the vehicle is an LS or an LT and checking the wheel diameter already on it. Once that is settled, the decision becomes choosing the right radial tire for the intended mix of appearance, ride, and regular road use.
Which Tire Size Is Right for The 2021 Chevrolet Trucks Trax
The 2021 Chevrolet Trucks Trax uses two primary tire sizes, and the difference comes down to sub-model and wheel diameter. Both fitments are radial, but one uses a 16-inch rim and the other uses an 18-inch rim, so confirming the exact Trax trim and the actual wheel size on the vehicle is the first step before choosing a replacement tire.
The 205/70R16 size uses a metric radial format: 205 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 16 is the rim diameter in inches. On the 2021 Chevrolet Trucks Trax, this size is one of the primary fitments and is tied to a 16-inch wheel setup. Its overall dimensions make it part of the standard fitment picture for this model, so the main job is confirming that the vehicle still has the correct wheel diameter and an unmodified suspension or wheel package before replacing tires.
The 215/55R18 size is also a metric radial, with a 215-millimeter nominal section width, a 55-series profile, radial construction, and an 18-inch rim diameter. For the 2021 Chevrolet Trucks Trax, this fitment belongs to the 18-inch wheel configuration rather than the 16-inch setup. Its dimensions are close in overall diameter to the other primary size, but the wheel requirement is different, so this size should be chosen only after verifying that the Trax is equipped with the matching 18-inch wheels and the correct trim-related fitment.
Sub-model fitment matters on the 2021 Chevrolet Trucks Trax because tire size changes with trim and wheel package. The LS stays straightforward with one primary size, while the LT can use either of the model's two radial fitments depending on the wheel setup on the vehicle.

2021 Chevrolet Trucks Trax LS
The 2021 Chevrolet Trucks Trax LS uses a single radial tire fitment, which makes replacement more straightforward than on trims with multiple wheel setups. Tire selection here is mainly about confirming the existing wheel diameter and choosing a replacement that matches the vehicle's current road-use needs.
The 2021 Chevrolet Trucks Trax LT can use either of the model's two radial tire sizes, so wheel confirmation is especially important before ordering replacements. Tire choice on an LT starts with checking whether the vehicle is on the 16-inch or 18-inch setup, then matching the replacement to that configuration.
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 2021 Chevrolet Trucks Trax usually center on the correct tire size by trim, the difference between the 16-inch and 18-inch setups, and what to inspect before replacing tires or putting the vehicle back into regular road use.
Tire Size & Fitment
What tire size fits a 2021 Chevrolet Trucks Trax?
The 2021 Chevrolet Trucks Trax uses two primary tire sizes: 205/70R16 and 215/55R18. Both are radial sizes, but they do not apply the same way across the model range. The LS uses 205/70R16, while the LT can be equipped with either 205/70R16 or 215/55R18 depending on the wheel setup on the vehicle.
That makes wheel confirmation the most important step before buying tires. A Trax with 16-inch wheels needs the 16-inch fitment, and a Trax with 18-inch wheels needs the 18-inch fitment. If the vehicle has had wheel changes since new, check the actual rim diameter on the car rather than relying only on the trim badge.
What size rim does a 2021 Chevrolet Trucks Trax use?
The 2021 Chevrolet Trucks Trax uses either a 16-inch rim or an 18-inch rim, depending on which primary tire size is on the vehicle. The 205/70R16 tire mounts on a 16-inch wheel, while the 215/55R18 tire mounts on an 18-inch wheel. Both are radial fitments for this model.
Rim diameter needs to match the tire exactly, so a 16-inch tire cannot be used on an 18-inch wheel and vice versa. It is also worth checking the wheel itself for markings if there is any doubt, especially on an LT or on a Trax that may have aftermarket wheels or a replacement wheel package.
Do all 2021 Chevrolet Trucks Trax sub-models use the same tire size?
No, the 2021 Chevrolet Trucks Trax sub-models do not all use the same tire size. The LS uses 205/70R16, while the LT can use either 205/70R16 or 215/55R18. That means trim level alone does not always settle the question unless the wheel size on the vehicle is also confirmed.
For practical replacement work, the LT is the trim that deserves extra attention. One LT may be set up on 16-inch wheels and another on 18-inch wheels, so the safest approach is to verify the current tire sidewall and wheel diameter before choosing a replacement. That helps avoid ordering the right size for the trim but the wrong size for the actual wheel.
Choosing the Right Tire
What should I consider when choosing a 205/70R16 tire for a 2021 Chevrolet Trucks Trax?
Start by confirming that the Trax actually uses the 205/70R16 fitment, since this size applies to the LS and can also appear on the LT. The size itself is a modern metric radial on a 16-inch rim, so the main selection question is choosing a replacement that matches the vehicle's existing wheel diameter and intended everyday driving use.
Beyond size, it helps to compare the overall condition of the wheels and whether the vehicle remains in its stock wheel and suspension configuration. A Trax used for routine commuting may simply need a straightforward same-size replacement, while a vehicle with wheel changes or suspension alterations should have clearance and wheel compatibility checked before a new tire is installed.
What should I consider when choosing a 215/55R18 tire for a 2021 Chevrolet Trucks Trax?
The first consideration is confirming that the Trax is equipped with the 18-inch wheel setup, since 215/55R18 is tied to that configuration. This metric radial size appears on certain LT applications, so the decision begins with matching the replacement tire to the actual wheel diameter rather than assuming every LT uses the same wheel package.
Once the wheel size is verified, the next step is making sure the vehicle still has enough clearance for the existing setup, especially if wheels or suspension have been changed. Staying with the same primary size helps preserve the intended fitment relationship, while any departure from the vehicle's current wheel-and-tire package deserves a closer check for rubbing or mismatch.
How do I choose between the available tires for a 2021 Chevrolet Trucks Trax?
Choosing the right tire for a 2021 Chevrolet Trucks Trax starts with the correct primary size, not with brand or appearance. Since this model uses either 205/70R16 or 215/55R18 depending on trim and wheel package, the right choice begins by identifying the exact wheel diameter and matching the tire size already fitted to the vehicle.
After that, compare tires based on how the Trax is actually used. A daily-driven crossover benefits from a properly matched same-size radial replacement and a sound wheel-and-suspension setup. If the vehicle has been modified or fitted with non-original wheels, selection should include a careful look at clearance, rim compatibility, and whether the current setup still reflects the intended fitment.
Restoration & Appearance
Does correct tire fitment matter for a 2021 Chevrolet Trucks Trax restoration?
Correct tire fitment still matters on a 2021 Chevrolet Trucks Trax, even though it is a modern crossover rather than a vintage collector vehicle. Using the proper primary size helps preserve the intended relationship between tire, wheel, and body clearance. On this model, that means staying with either 205/70R16 or 215/55R18 according to the actual wheel setup.
Appearance and originality on a newer vehicle usually come down to keeping the right wheel-and-tire package for the trim and avoiding mismatched replacements. A restoration-minded owner should confirm whether the Trax remains on its original-style wheel diameter before replacing tires, since the visual stance of the vehicle changes quickly when the wrong size is installed.
Which tire should I choose for a period-style 2021 Chevrolet Trucks Trax?
A period-style choice for a 2021 Chevrolet Trucks Trax is usually the same primary radial size that matches the vehicle's original wheel configuration. That means 205/70R16 on the 16-inch setup or 215/55R18 on the 18-inch setup. Because this is a recent model, keeping the correct size matters more than seeking vintage-style construction or sidewall treatments.
The most convincing stock-style presentation comes from matching the tire to the wheel diameter already associated with the vehicle's trim and stance. Owners aiming for a clean, original-looking result should verify the current wheel package first, especially on an LT, then avoid substitutions that change the visual proportion of the tire and wheel without a clear fitment reason.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Chevrolet Trucks Trax?
Yes, modifications can affect tire fitment on a 2021 Chevrolet Trucks Trax. Wheel changes, altered offsets, suspension lowering, and other chassis changes can all influence how a 205/70R16 or 215/55R18 tire sits in the wheel opening. Even when the tire size itself is one of the correct primary fitments, the surrounding hardware can change the available clearance.
That is why a modified Trax should be checked at full steering lock and through normal suspension movement before settling on replacement tires. Clearance to the fender, inner liner, and suspension parts matters just as much as the size printed on the sidewall. A stock-size tire on a non-stock wheel can still create fitment issues.
What should I inspect before driving a 2021 Chevrolet Trucks Trax on new tires?
Before driving a 2021 Chevrolet Trucks Trax on new tires, inspect the wheel diameter, confirm the tire size matches the vehicle's setup, and check that each tire is properly seated and inflated. It is also smart to look over the wheels for damage and make sure there is no visible interference with the fender liners, suspension components, or steering parts.
A short initial road test can reveal vibration, pulling, or rubbing that may not be obvious in the garage. After installation, recheck tire pressure and keep an eye on how the Trax behaves over turns, bumps, and parking-lot steering angles. That extra attention is especially worthwhile if the vehicle has aftermarket wheels or recently changed suspension parts.
How often should tires on a 2021 Chevrolet Trucks Trax be inspected?
Tires on a 2021 Chevrolet Trucks Trax should be inspected regularly rather than only when they look flat or worn out. A routine visual check for uneven tread wear, cuts, cracking, bulges, and air loss helps catch problems early. That matters whether the vehicle is using 205/70R16 or 215/55R18, since both sizes depend on proper inflation and sound condition.
A practical habit is to inspect the tires before longer trips and any time the Trax has been parked for an extended period. Pressure should be checked with a gauge, not by appearance alone. Uneven wear can also point to alignment or suspension issues, so repeated wear patterns deserve attention before they shorten the life of the replacement tires.
