The 2020 Chevrolet Trucks Trax sits in the modern compact crossover category, blending city-friendly dimensions with everyday utility and a taller driving position than a traditional small car. Buyers often approach a Trax tire search with practicality in mind, but exact fitment still matters because this model uses more than one primary size across the lineup. The 2020 Chevrolet Trucks Trax uses radial tires in either 205/70R16 or 215/55R18, depending on sub-model and wheel setup. That makes the first step confirming whether the vehicle is on a 16-inch or 18-inch rim. Once that is settled, the focus shifts to choosing the right tire within the correct size for ride, appearance, and intended road use.
Which Tire Size Is Right for The 2020 Chevrolet Trucks Trax
The 2020 Chevrolet Trucks Trax uses two primary tire sizes, and the correct one depends on the specific sub-model and wheel diameter. Both are radial fitments, but the difference between a 16-inch and 18-inch rim means the first step is confirming exactly which wheels are on the vehicle before comparing tire choices.
205/70R16 is a metric radial size in which 205 identifies the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 16 is the rim diameter in inches. On the 2020 Chevrolet Trucks Trax, this size is part of the primary fitment range and is used on 16-inch wheels. Its dimensions make it distinct from the 18-inch option even though overall diameter stays very close. This is the size to evaluate when the vehicle is equipped with the smaller wheel package or when a sub-model is associated with the 16-inch setup.
215/55R18 is a metric radial size where 215 is the nominal section width in millimeters, 55 is the aspect ratio, R designates radial construction, and 18 identifies the rim diameter in inches. On the 2020 Chevrolet Trucks Trax, this size belongs to the 18-inch wheel fitment and should be treated separately from the 16-inch setup. Even with a similar overall tire diameter, the wheel requirement is different and must be matched correctly. This size becomes the relevant choice when the Trax is on the larger factory-style wheel package or a sub-model associated with 18-inch rims.
Sub-model fitment matters on the 2020 Chevrolet Trucks Trax because tire size is not the same across the entire lineup. Some versions use one wheel and tire package, while the LT can be found with either of the two primary sizes, so the exact trim and wheel setup should be confirmed first.

2020 Chevrolet Trucks Trax LS
The 2020 Chevrolet Trucks Trax LS uses the 205/70R16 radial tire size. That keeps selection focused on the correct 16-inch fitment, with wheel diameter confirmation still worthwhile if the vehicle has been changed from its original setup.
The 2020 Chevrolet Trucks Trax LT can use either 205/70R16 or 215/55R18, making it the sub-model where wheel verification is especially important. Tire selection starts by confirming whether the vehicle is on 16-inch or 18-inch rims before comparing replacement options.
The 2020 Chevrolet Trucks Trax Premier uses the 215/55R18 radial tire size. That points the search toward the 18-inch wheel fitment and makes it important to stay with the correct rim diameter unless the vehicle has been intentionally modified.
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
For the 2020 Chevrolet Trucks Trax, the key questions center on identifying the correct tire size by sub-model and wheel diameter, then making smart replacement choices around rim fitment, tire selection, and road-use checks.
Tire Size & Fitment
What tire size fits a 2020 Chevrolet Trucks Trax?
The 2020 Chevrolet Trucks Trax uses either 205/70R16 or 215/55R18, depending on the sub-model and wheel package. Both are radial tire sizes, but they are not interchangeable as primary fitments because they require different rim diameters.
The practical first step is checking whether the vehicle is on a 16-inch or 18-inch wheel. An LS uses 205/70R16, a Premier uses 215/55R18, and an LT may use either size, so the exact trim and actual wheel setup should be confirmed before choosing a replacement tire.
What size rim does a 2020 Chevrolet Trucks Trax use?
A 2020 Chevrolet Trucks Trax uses either a 16-inch or 18-inch rim, depending on tire size and sub-model. The 205/70R16 fitment uses a 16-inch rim, while the 215/55R18 fitment uses an 18-inch rim.
Rim diameter is the most important fitment check because a tire must match the wheel it mounts on. Looking only at overall tire height is not enough, especially since these two Trax sizes have very similar overall diameters but fit different wheels. Check the tire sidewall and the wheel setup on the vehicle before ordering.
Do all 2020 Chevrolet Trucks Trax sub-models use the same tire size?
No, the 2020 Chevrolet Trucks Trax does not use one tire size across all sub-models. The LS uses 205/70R16, the Premier uses 215/55R18, and the LT can use either 205/70R16 or 215/55R18.
That variation means trim level matters, but actual wheel diameter matters just as much. The LT especially should be checked carefully because it appears with both fitments. Matching the replacement tire to the existing wheel is the right starting point, and any vehicle with aftermarket wheels should be measured rather than assumed.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Chevrolet Trucks Trax?
Start with the correct primary size for the vehicle: 205/70R16 or 215/55R18. The right choice depends on the Trax sub-model and, more importantly, the wheel diameter currently on the vehicle, since each size is built for a different rim.
After the size is confirmed, compare tires based on the kind of driving the Trax sees most often, along with general fitment details such as wheel compatibility and condition. A daily-driven crossover benefits from getting the exact size right first, because that preserves the intended relationship between tire height, width, and wheel diameter.
How do I choose between the available 2020 Chevrolet Trucks Trax tire sizes?
You do not choose between 205/70R16 and 215/55R18 as interchangeable options for the same wheel. The correct size is determined by the Trax sub-model and the wheel diameter on the vehicle, with 16-inch and 18-inch fitments serving different setups.
The useful comparison comes after the wheel size is verified. An LT may require extra attention because it can use either size, while LS and Premier fitment is more straightforward. Checking the current tire sidewall and measuring the wheel saves time and avoids selecting a tire that matches the vehicle generally but not the actual rim.
What rim-fitment details should I compare when choosing 2020 Chevrolet Trucks Trax tires?
The main rim-fitment detail on a 2020 Chevrolet Trucks Trax is diameter. A 205/70R16 tire belongs on a 16-inch rim, and a 215/55R18 tire belongs on an 18-inch rim, so the tire must match the wheel exactly at that point.
Wheel setup matters beyond the trim badge, especially on a used vehicle. A Trax that has had wheel changes, replacement rims, or previous owner modifications should be checked directly at the vehicle. Matching the tire size to the actual rim diameter first helps prevent fitment issues before any further comparison of tire type or intended use.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Chevrolet Trucks Trax?
Yes, correct tire fitment matters on a 2020 Chevrolet Trucks Trax because the model uses two distinct modern radial sizes tied to two different wheel diameters. Staying with the proper size preserves the intended relationship between the tire and the wheel package on that specific version of the vehicle.
Appearance also depends on getting the fitment right. A tire mounted to the wrong diameter wheel is not simply a styling issue; it is a compatibility issue. For owners who want the Trax to retain a clean, proper presentation, confirming the exact size already on the vehicle is the simplest place to start.
Which tire should I choose for a stock-style 2020 Chevrolet Trucks Trax?
A stock-style replacement for a 2020 Chevrolet Trucks Trax begins with using the same primary size that belongs on the vehicle's current wheel setup. That means 205/70R16 for the 16-inch fitment or 215/55R18 for the 18-inch fitment, depending on the sub-model and wheel package.
The LT deserves extra attention because it can appear with either configuration. Keeping a stock-style look is less about picking between sizes and more about matching the existing wheel diameter correctly. On a used Trax, checking the sidewall and the wheel itself is more reliable than assuming the present setup matches the original trim specification.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Chevrolet Trucks Trax?
Yes, modifications can affect tire fitment on a 2020 Chevrolet Trucks Trax. Wheel changes, suspension alterations, or previous owner replacements can move the vehicle away from its original 205/70R16 or 215/55R18 setup, even when the trim level suggests one particular fitment.
That is why the tire sidewall and actual wheel diameter should be checked before selecting replacements. A lowered vehicle, an aftermarket wheel package, or changes in wheel width can all influence the right tire choice. On an LT especially, relying on the trim name alone is less dependable than verifying what is physically on the vehicle.
What should I inspect before driving a 2020 Chevrolet Trucks Trax on new tires?
Before driving a 2020 Chevrolet Trucks Trax on new tires, confirm that the tire size matches the wheel diameter and that all four tires are in the intended fitment. It is also wise to inspect inflation pressure, valve condition, and basic mounting quality before the vehicle returns to normal road use.
A broader inspection should include tread seating, visible sidewall condition, and any signs of rubbing during steering movement. The vehicle itself should also be in sound condition, particularly if it has uneven wear history or prior wheel changes. A short initial drive followed by a pressure recheck is a sensible way to confirm everything is settling properly.
How often should tires on a 2020 Chevrolet Trucks Trax be inspected?
Tires on a 2020 Chevrolet Trucks Trax should be inspected regularly, not only when replacement time arrives. Routine checks for pressure loss, uneven wear, cuts, bulges, and sidewall damage help catch problems early, whether the vehicle uses 205/70R16 or 215/55R18 tires.
Regular inspection becomes even more important if the Trax sees rough roads, curb contact, or long intervals between service visits. A quick visual check and pressure check every month is a practical habit, and any vibration, pull, or rubbing sound deserves prompt attention. Consistent inspection helps protect both tire life and everyday drivability.
