The 2018 Chevrolet Trucks Trax sits in the modern compact crossover class, where everyday drivability, city-friendly size, and practical versatility matter more than oversized hardware. Buyers looking at this exact model are usually balancing straightforward replacement needs with the reality that wheel and trim differences can change the tire fitment. The 2018 Chevrolet Trucks Trax uses radial tires, with 205/70R16 and 215/55R18 both appearing across the model range. That means the key decision is not just brand or tread pattern, but confirming whether the vehicle is on 16-inch or 18-inch wheels. Getting that right first helps keep the replacement choice aligned with ride height, appearance, and normal clearance.
Which Tire Size Is Right for The 2018 Chevrolet Trucks Trax
Two primary tire sizes apply to the 2018 Chevrolet Trucks Trax, and the correct choice depends on the exact sub-model and wheel setup. Both sizes are radial, but they use different rim diameters, so the first step is confirming whether the vehicle is equipped with 16-inch or 18-inch wheels before comparing replacement tire options.
205/70R16 is a metric radial size in which 205 identifies the nominal section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 16 is the wheel diameter in inches. On the 2018 Chevrolet Trucks Trax, this size serves the 16-inch wheel fitment used on certain sub-models. Its overall dimensions keep it closely aligned with the crossover's intended stance and everyday road use. This is the size to evaluate when the Trax is equipped with the smaller factory-style wheel package and a replacement tire needs to match that setup.
215/55R18 is a metric radial size with a 215-millimeter nominal section width, a 55-series profile, and fitment for an 18-inch wheel. On the 2018 Chevrolet Trucks Trax, this size belongs to the larger wheel configuration used on specific trims. Its sizing keeps the overall tire diameter very close to the 16-inch package while changing the wheel-to-sidewall proportion. This is the correct fitment to consider when the vehicle has 18-inch wheels and the goal is to stay with the proper tire size for that wheel diameter.
Sub-model fitment matters on the 2018 Chevrolet Trucks Trax because tire size changes with trim and wheel package. Some versions stay with one size only, while the LT can use either 16-inch or 18-inch wheel fitment, making wheel confirmation especially important before replacement.

2018 Chevrolet Trucks Trax LS
The 2018 Chevrolet Trucks Trax LS uses the 205/70R16 radial tire size. Tire selection is more straightforward here, with the main task being a proper 16-inch replacement that matches the existing wheel setup and intended driving use.
The 2018 Chevrolet Trucks Trax LT can use either 205/70R16 or 215/55R18, depending on how the vehicle is equipped. That makes the wheel diameter the first thing to verify, since choosing between the two sizes starts with confirming whether the LT is on 16-inch or 18-inch rims.
The 2018 Chevrolet Trucks Trax Premier uses the 215/55R18 radial tire size. Tire selection should stay focused on the 18-inch wheel fitment, with attention to maintaining the correct size rather than substituting a different diameter without checking the full wheel and clearance setup.
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
Tire questions for the 2018 Chevrolet Trucks Trax usually come down to size by trim, 16-inch versus 18-inch wheel fitment, and how to confirm the right replacement before road use.
Tire Size & Fitment
What tire size fits a 2018 Chevrolet Trucks Trax?
The 2018 Chevrolet Trucks Trax uses two primary tire sizes: 205/70R16 and 215/55R18. Both are radial tires, but they do not fit the same wheel diameter. The 16-inch size appears on the LS and some LT configurations, while the 18-inch size appears on the Premier and some LT configurations.
The practical step is to confirm the exact trim and the wheel diameter currently on the vehicle before choosing a replacement. An LT needs extra attention because it can use either size. Checking the tire sidewall and measuring the wheel diameter helps prevent ordering a tire that matches the model name but not the actual wheel setup.
What size rim does a 2018 Chevrolet Trucks Trax use?
A 2018 Chevrolet Trucks Trax uses either a 16-inch or 18-inch rim, depending on the sub-model and wheel package. The 205/70R16 tire mounts on a 16-inch rim, and the 215/55R18 tire mounts on an 18-inch rim. Both fitments are radial, but the wheel diameter changes with the tire size.
Wheel diameter should be confirmed before anything else because a 16-inch tire cannot be mounted on an 18-inch wheel, and the reverse is also true. Looking at the existing tire sidewall is usually the quickest check. On LT models especially, confirming the wheel setup avoids confusion since that trim appears with both tire sizes.
Why does the 2018 Chevrolet Trucks Trax have more than one tire size?
The 2018 Chevrolet Trucks Trax has more than one tire size because different sub-models and wheel packages use different wheel diameters. The model range includes both 205/70R16 and 215/55R18 fitments. The LT is the main crossover point, since it can appear with either size depending on how the vehicle is equipped.
That difference does not mean the sizes are automatically interchangeable on the same vehicle. It means the correct replacement depends on the wheels actually installed. A buyer should verify the trim, read the current tire sidewall, and confirm the wheel diameter before comparing replacement options, especially if the vehicle has had previous wheel changes or aftermarket upgrades.
Choosing the Right Tire
What should I consider when choosing a 205/70R16 or 215/55R18 tire for a 2018 Chevrolet Trucks Trax?
Start with the correct size for the exact 2018 Chevrolet Trucks Trax configuration. The two primary choices are 205/70R16 and 215/55R18, and each matches a different wheel diameter. Because both are radial sizes, the main decision is not tire construction but choosing the size that matches the wheel setup already on the vehicle.
After size confirmation, compare practical factors such as intended driving use, ride preference, tread design, and whether the vehicle remains on its original wheels. It also helps to look at overall condition around the wheel and suspension area. A tire that matches the correct diameter and size code is the right starting point before considering any other feature.
How do I choose between the available 2018 Chevrolet Trucks Trax tire sizes?
The choice between 205/70R16 and 215/55R18 is determined by the wheel diameter on the vehicle, not by personal preference alone. A 2018 Chevrolet Trucks Trax on 16-inch wheels uses 205/70R16, while one on 18-inch wheels uses 215/55R18. The LT can use either, depending on its wheel package.
The best way to sort that out is to inspect the tire sidewall already on the vehicle and confirm the wheel size directly. That matters more than trim name by itself when wheels may have been changed over time. Once the wheel diameter is confirmed, the correct tire size becomes much clearer and easier to shop for confidently.
How do I choose between the available radial tires for a 2018 Chevrolet Trucks Trax?
All primary fitments for the 2018 Chevrolet Trucks Trax are radial, so the decision stays focused on the correct size and the type of road use the vehicle sees most often. The first step is matching 205/70R16 to a 16-inch setup or 215/55R18 to an 18-inch setup. Everything else comes after that.
Once the size is right, compare replacement tires in terms of how the Trax is actually used, such as daily commuting, highway driving, or occasional light-duty utility use. It also makes sense to keep the vehicle's wheel package consistent rather than mixing sizes casually. A properly matched radial tire supports the intended stance and clearance of the existing setup.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Chevrolet Trucks Trax restoration or clean stock-style rebuild?
Yes, correct tire fitment still matters even on a modern vehicle like the 2018 Chevrolet Trucks Trax. Keeping the proper 205/70R16 or 215/55R18 size helps preserve the intended wheel-to-tire proportions and avoids changing the appearance with an obviously mismatched sidewall height or wheel diameter relationship.
A stock-style rebuild should begin by confirming which wheel package belongs on the specific sub-model and which size is currently fitted. That is especially important on the LT, where both sizes appear. Appearance is only part of the decision, since the wrong diameter can also create avoidable issues with clearance, stance, and general fitment confidence.
How does tire size affect the appearance of a 2018 Chevrolet Trucks Trax?
Tire size changes the visual balance of the 2018 Chevrolet Trucks Trax because 205/70R16 and 215/55R18 pair with different wheel diameters and sidewall proportions. Even though their overall diameters are very close, the 16-inch setup shows more sidewall, while the 18-inch setup gives the wheel a larger visual presence.
That means appearance should be considered alongside fitment, especially if the goal is to maintain a stock-style look for a specific trim. The right approach is to match the tire to the wheel diameter already on the vehicle rather than chasing a different look through an incorrect size. Keeping the proper combination helps the Trax look properly proportioned.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Chevrolet Trucks Trax?
Yes, modifications can affect tire fitment on a 2018 Chevrolet Trucks Trax. Aftermarket wheels, suspension changes, altered ride height, or body modifications can all change the space available for a 205/70R16 or 215/55R18 tire. Even when the tire size stays the same, wheel specifications can influence how the tire sits in the wheel opening.
That is why the actual vehicle setup should be checked before replacement if anything appears different from stock. Looking at wheel diameter, wheel width, and visible clearance around the strut, fender, and steering range helps avoid fitment surprises. A trim-based tire size guide is useful, but a modified vehicle always deserves a hands-on confirmation step.
What should I inspect before driving a 2018 Chevrolet Trucks Trax on new tires?
Before driving a 2018 Chevrolet Trucks Trax on new tires, inspect the wheel condition, verify that the installed tire size matches the vehicle's 16-inch or 18-inch setup, and make sure the tires are properly inflated. It also helps to check for obvious interference, confirm lug hardware is secure, and look over the valve stems carefully.
A short, careful road test is a smart follow-up because it can reveal vibration, rubbing, or steering issues that were not obvious at a standstill. Rechecking pressure after the first drive is also worthwhile. On a vehicle with previous wheel or suspension changes, that first inspection matters even more than simply matching the sidewall size.
How often should tires on a 2018 Chevrolet Trucks Trax be inspected?
Tires on a 2018 Chevrolet Trucks Trax should be inspected regularly rather than only when replacement is due. Routine checks should include tread wear, cuts, bulges, cracking, and signs of uneven wear that may point to alignment or suspension concerns. Pressure should also be checked consistently, since low pressure can affect both wear and everyday drivability.
A practical rhythm is to inspect them visually whenever the vehicle is washed or fueled and to look more closely before longer trips. Any Trax that sits for extended periods still deserves periodic checks, because age and air loss can become issues even without heavy mileage. Staying ahead of those basics helps preserve correct fitment and road readiness.
