The 2019 Chevrolet Trucks Traverse is a three-row crossover built for family travel, cargo capacity, and everyday road comfort rather than vintage-style tire decisions. Even so, exact fitment still matters because this Traverse uses two different primary tire sizes depending on sub-model and wheel package: 255/65R18 and 255/55R20, both in radial construction. That means the first step is confirming the vehicle's trim and actual wheel diameter before comparing tires. Once that is settled, the choice becomes more practical, focusing on the correct metric size, wheel compatibility, and the tire option that best suits the vehicle's intended road use and overall setup.
Which Tire Size Is Right for The 2019 Chevrolet Trucks Traverse
The 2019 Chevrolet Trucks Traverse uses two primary tire sizes, and the correct one depends on sub-model and wheel diameter. Both sizes are metric radial fitments, but one is built around an 18-inch rim and the other around a 20-inch rim, so confirming the exact trim and the wheels currently on the vehicle is the first step before choosing a replacement tire.
A 255/55R20 tire uses a 255-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2019 Chevrolet Trucks Traverse, this size is used on certain sub-models and wheel packages, so it should be matched to the vehicle's actual 20-inch wheels rather than chosen by model name alone. Its dimensions keep it in the same general overall diameter range as the 18-inch fitment while pairing with a larger wheel. This size is the one to evaluate when the Traverse is equipped with the factory-style 20-inch setup and proper clearance has been confirmed.
A 255/65R18 tire also uses a 255-millimeter nominal section width and radial construction, but its 65-series profile is designed for an 18-inch rim. On the 2019 Chevrolet Trucks Traverse, this size applies to trims or configurations running the 18-inch wheel setup, making wheel diameter the key fitment checkpoint. Although it shares nearly the same overall diameter and section width as the 20-inch fitment, it is not selected interchangeably because the rim diameter is different. This is the correct size to focus on when the vehicle retains 18-inch wheels and stock-style clearance.
Tire fitment on the 2019 Chevrolet Trucks Traverse varies by sub-model, and some trims were available with more than one primary size. Checking the exact trim and confirming whether the vehicle has 18-inch or 20-inch wheels is the most important step before selecting a tire.

2019 Chevrolet Trucks Traverse High Country
The 2019 Chevrolet Trucks Traverse High Country uses the 255/55R20 radial size, placing it on the 20-inch wheel fitment. Tire selection for this trim starts with staying in that metric radial size and confirming the vehicle still has its 20-inch wheel setup.
The 2019 Chevrolet Trucks Traverse L uses the 255/65R18 radial size, which corresponds to the 18-inch wheel configuration. That makes replacement selection fairly straightforward as long as the vehicle has not been changed to a different wheel diameter.
The 2019 Chevrolet Trucks Traverse LS can use either 255/65R18 or 255/55R20, depending on the wheel package on the vehicle. Tire choice for an LS begins with physically confirming wheel diameter, since the two sizes are tied to different rims rather than being interchangeable options on the same wheel.
The 2019 Chevrolet Trucks Traverse LT also appears with either 255/65R18 or 255/55R20, so trim name alone is not enough to choose a tire. The practical next step is checking whether the vehicle is running 18-inch or 20-inch wheels before comparing replacement options.
The 2019 Chevrolet Trucks Traverse Premier uses the 255/55R20 radial size and is tied to the 20-inch wheel fitment. Replacement decisions should stay centered on that size unless the vehicle has been modified with a different wheel and tire package.
The 2019 Chevrolet Trucks Traverse RS uses the 255/55R20 radial size on a 20-inch wheel. Tire selection for this trim is mainly a matter of choosing the right replacement within that size and confirming the current wheel setup matches the intended fitment.
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 2019 Chevrolet Trucks Traverse, the most common tire questions center on the two factory fitment sizes, the difference between 18-inch and 20-inch wheel setups, and what to inspect before choosing replacement tires or heading back onto the road.
Tire Size & Fitment
What tire size fits a 2019 Chevrolet Trucks Traverse?
The 2019 Chevrolet Trucks Traverse uses two primary tire sizes: 255/65R18 and 255/55R20. Both are radial metric sizes, but they do not apply across every Traverse trim in the same way, because they are tied to different wheel diameters and sub-model configurations.
Choosing the right one starts with identifying the exact trim and then confirming the wheel diameter actually on the vehicle. LS and LT models can appear with either size, while other trims are tied to one fitment, so checking the tire sidewall or wheel size is more reliable than assuming by model name alone.
What size rim does a 2019 Chevrolet Trucks Traverse use?
A 2019 Chevrolet Trucks Traverse uses either an 18-inch or 20-inch rim, depending on sub-model and wheel package. The 255/65R18 tire is built for an 18-inch rim, while the 255/55R20 tire is built for a 20-inch rim.
Rim diameter is the first fitment detail to verify because the two tire sizes are not mounted on the same wheel. A quick check of the current tire sidewall, wheel stamping, or existing vehicle setup helps prevent ordering the right width and profile in the wrong rim diameter.
Why does the 2019 Chevrolet Trucks Traverse have more than one tire size?
The 2019 Chevrolet Trucks Traverse has more than one tire size because different trims and wheel packages use different rim diameters. One setup uses 255/65R18 on an 18-inch wheel, and the other uses 255/55R20 on a 20-inch wheel, while keeping a very similar overall tire diameter.
That approach lets the vehicle use different wheel presentations without drastically changing its overall tire height. For replacement purposes, the key point is that similar outside dimensions do not make the sizes interchangeable, since the tires are still designed for different rims.
Choosing the Right Tire
What should I consider when choosing a 255/55R20 tire for a 2019 Chevrolet Trucks Traverse?
A 255/55R20 tire for a 2019 Chevrolet Trucks Traverse should first match the vehicle's actual 20-inch wheel setup. After size confirmation, the main considerations are staying with the correct metric radial dimensions, checking that the wheel condition is sound, and selecting a tire suited to the Traverse's normal passenger and cargo use.
It also helps to verify that the vehicle has not been changed with aftermarket wheels, altered suspension height, or body modifications that affect clearance. Even within the correct size, replacement decisions should account for how the Traverse is driven, loaded, and maintained rather than relying on trim name alone.
What should I consider when choosing a 255/65R18 tire for a 2019 Chevrolet Trucks Traverse?
A 255/65R18 tire is appropriate for a 2019 Chevrolet Trucks Traverse equipped with the 18-inch wheel fitment. The first step is confirming that the vehicle still uses 18-inch wheels, then choosing a radial tire that matches the size and is appropriate for the vehicle's regular road use and load demands.
Buyers should also inspect the current wheel and tire setup for any prior changes that might affect replacement selection. A Traverse that has been modified, fitted with nonstock wheels, or driven with unusual cargo demands deserves an extra check for wheel compatibility, clearance, and overall condition before installation.
How do I choose between the available tire sizes for a 2019 Chevrolet Trucks Traverse?
The two tire sizes used on a 2019 Chevrolet Trucks Traverse are not alternate choices on the same rim. Selection comes down to the wheel diameter already on the vehicle: 255/65R18 for 18-inch wheels or 255/55R20 for 20-inch wheels, with trim and package helping narrow the answer.
The most reliable approach is to check the current tire sidewall and confirm the vehicle's actual wheel setup before replacing anything. This matters most on LS and LT models, where either fitment may be present, and it becomes even more important if the Traverse has ever received aftermarket wheels.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Chevrolet Trucks Traverse restoration?
Correct tire fitment still matters on a 2019 Chevrolet Trucks Traverse even though it is a modern crossover rather than a traditional restoration vehicle. The right size preserves the intended relationship between wheel diameter, tire profile, and the vehicle's stance, with 255/65R18 and 255/55R20 tied to different factory-style wheel setups.
Owners bringing one back to stock-style appearance should start by confirming the original wheel diameter for that exact trim and current vehicle configuration. Keeping the proper size on the proper rim helps maintain a consistent look and avoids the mismatched appearance that can come from using the wrong wheel-and-tire combination.
Which tire fitment best suits a stock-style 2019 Chevrolet Trucks Traverse?
A stock-style 2019 Chevrolet Trucks Traverse is best served by retaining the primary tire size that matches its trim and wheel diameter. That means 255/65R18 on the 18-inch setup or 255/55R20 on the 20-inch setup, both in radial construction, rather than mixing sizes across wheel formats.
The visual result is just as important as the measurement itself, because wheel diameter and sidewall profile shape the Traverse's overall presentation. Anyone aiming for an original-style appearance should verify the current wheels first and avoid assuming that another Traverse trim's tire size is appropriate for the vehicle at hand.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Chevrolet Trucks Traverse?
Modifications can absolutely affect tire fitment on a 2019 Chevrolet Trucks Traverse. Wheel changes, suspension lowering or lifting, offset differences, and body alterations can all change how a 255/65R18 or 255/55R20 tire sits in the wheel opening, even when the size itself matches a known Traverse fitment.
A Traverse with aftermarket wheels deserves a closer look at rim diameter, width, and clearance at full steering lock and suspension movement. That extra check is especially important on LS and LT trims, since either factory wheel size may already be present before any custom changes are considered.
What should I inspect before driving a 2019 Chevrolet Trucks Traverse on new tires?
Before driving a 2019 Chevrolet Trucks Traverse on new tires, inspect the wheel condition, verify the installed size matches the vehicle's 18-inch or 20-inch setup, and confirm proper inflation. It also helps to check for visible clearance around the suspension, fenders, and steering components once the new tires are mounted.
A short initial road test can reveal vibration, rubbing, or pull that needs attention before regular use. Rechecking inflation after installation and making sure lug hardware is properly secured are sensible final steps, especially if the vehicle has sat for a while or recently received wheel-related service.
What should I check before a longer drive in a 2019 Chevrolet Trucks Traverse?
Before a longer drive in a 2019 Chevrolet Trucks Traverse, make sure the tires are the correct size for the vehicle's wheels, inspect for cuts, bulges, irregular wear, and air loss, and confirm inflation while the tires are cold. Those basic checks matter whether the vehicle runs 255/65R18 or 255/55R20.
Longer trips also make it worth checking the spare, overall tread condition, and any sign of rubbing if the Traverse has different wheels or suspension changes. A clean visual inspection around all four wheel openings can catch small problems early, before they become a roadside issue.
