The 2022 Cadillac Trucks XT5 sits in the modern luxury crossover space, balancing everyday comfort with the sharper road manners buyers expect from a premium midsize utility vehicle. Its clean, contemporary styling and upscale character make tire choice less about vintage-style construction and more about matching the vehicle’s exact wheel setup. The 2022 Cadillac Trucks XT5 uses radial tires in two primary sizes, 235/65R18 and 235/55R20, depending on trim and wheel package. That means the key decision is confirming whether the vehicle is on 18-inch or 20-inch wheels, then choosing a tire that matches the intended mix of appearance, ride quality, and routine road use.
Which Tire Size Is Right for The 2022 Cadillac Trucks XT5
Two tire sizes apply to the 2022 Cadillac Trucks XT5, and the correct choice depends on the vehicle’s exact sub-model and wheel diameter. Both are radial metric sizes, but they fit different rim diameters, so the first step is confirming whether the XT5 is equipped with 18-inch or 20-inch wheels before comparing tire options.
The size 235/55R20 identifies a metric radial tire that is 235 millimeters wide, uses a 55-series aspect ratio, and fits a 20-inch rim. On the 2022 Cadillac Trucks XT5, this size is part of the larger-wheel fitment and is used across every Sport model as well as some Luxury and Premium Luxury configurations. Its overall dimensions keep it close in height to the 18-inch fitment while pairing with a different wheel package. This is the size to evaluate when the XT5 already wears 20-inch wheels and the goal is to stay with the proper metric radial fitment.
The size 235/65R18 is a metric radial with a 235-millimeter section width, a 65-series profile, and an 18-inch rim diameter. For the 2022 Cadillac Trucks XT5, this size appears on certain Luxury and Premium Luxury versions that use the smaller wheel package. It carries essentially the same section width as the 20-inch fitment, but the tire and wheel relationship is different because the rim diameter changes. This is the size to confirm when the XT5 is equipped with 18-inch wheels and the owner wants to maintain the correct wheel-to-tire combination.
Sub-model fitment matters on the 2022 Cadillac Trucks XT5 because wheel and tire combinations are not completely uniform across the lineup. Luxury and Premium Luxury models can use either 18-inch or 20-inch fitment, while Sport models stay with the 20-inch radial size.

2022 Cadillac Trucks XT5 Luxury
The 2022 Cadillac Trucks XT5 Luxury can use either of the two radial tire sizes associated with this model range, depending on the wheel package installed on the vehicle. Tire selection starts with confirming whether the Luxury trim is on 18-inch or 20-inch wheels before comparing replacement options.
The 2022 Cadillac Trucks XT5 Premium Luxury also appears with either primary radial fitment, so wheel diameter needs to be verified before choosing a tire. Once the rim size is confirmed, the decision becomes selecting the correct metric radial size for the vehicle’s existing setup.
The 2022 Cadillac Trucks XT5 Sport uses the 20-inch radial fitment rather than sharing both wheel sizes used elsewhere in the XT5 range. That makes tire selection more straightforward, though the owner should still confirm the actual wheel setup if the vehicle has been changed from stock.
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 2022 Cadillac Trucks XT5 usually center on the correct tire size by trim, the difference between the 18-inch and 20-inch fitments, and what to inspect before replacing tires on a luxury crossover that may already have wheel or suspension changes.
Tire Size & Fitment
What tire size fits a 2022 Cadillac Trucks XT5?
The 2022 Cadillac Trucks XT5 uses two primary tire sizes: 235/55R20 and 235/65R18. Both are radial metric sizes, but they do not fit the same wheel diameter, so they are tied to different wheel setups within the XT5 lineup.
The practical step is to confirm the wheel diameter already on the vehicle before ordering tires. Luxury and Premium Luxury models can appear with either size, while the Sport uses 235/55R20, so the correct choice depends on the trim and the actual wheels installed on that specific XT5.
What size rim does a 2022 Cadillac Trucks XT5 use?
A 2022 Cadillac Trucks XT5 uses either an 18-inch rim or a 20-inch rim, depending on the tire size and sub-model configuration. The 235/65R18 tire fits an 18-inch wheel, while the 235/55R20 tire fits a 20-inch wheel.
That rim difference is the first thing to verify because the two tire sizes are not interchangeable across those wheel diameters. Checking the sidewall marking on the current tire or confirming the wheel size directly helps prevent ordering the right width and profile in the wrong rim diameter.
Do all 2022 Cadillac Trucks XT5 sub-models use the same tire size?
No, not every 2022 Cadillac Trucks XT5 sub-model uses the same tire size. Luxury and Premium Luxury models can use either 235/65R18 or 235/55R20, while the Sport is associated with 235/55R20 only.
That means trim level alone is helpful, but the actual wheel setup still matters on Luxury and Premium Luxury vehicles. A quick check of the tire sidewall or wheel diameter is the safest way to confirm fitment, especially if the XT5 was purchased used or has had wheels replaced since new.
Choosing the Right Tire
What should I consider when choosing a tire for a 2022 Cadillac Trucks XT5?
Start with the exact tire size already fitted to the vehicle, either 235/65R18 or 235/55R20, because the XT5 uses two different rim diameters. Since both are radial metric sizes, the main selection issue is matching the tire to the wheel package rather than choosing between old and new construction types.
After size is confirmed, compare the tire’s intended use with how the XT5 is driven. Daily commuting, highway travel, and seasonal road conditions can all influence the kind of replacement tire that makes the most sense, but the correct starting point is always the existing wheel diameter and corresponding size.
How do I choose between the available 2022 Cadillac Trucks XT5 tire sizes?
The two XT5 tire sizes are chosen by vehicle configuration, not by preference alone. A 2022 Cadillac Trucks XT5 on 18-inch wheels uses 235/65R18, while one on 20-inch wheels uses 235/55R20, so the right choice follows the wheel diameter already on the vehicle.
If the XT5 still has its original wheel setup, the current sidewall marking is usually the quickest confirmation. On a used vehicle, it is smart to verify that the wheel diameter, tire size, and trim all line up, because replacement decisions become more complicated once aftermarket wheels have been installed.
Why does the 2022 Cadillac Trucks XT5 have more than one tire size?
The 2022 Cadillac Trucks XT5 has more than one tire size because different trims and wheel packages use different rim diameters. The 18-inch fitment uses 235/65R18, and the 20-inch fitment uses 235/55R20, giving the model range more than one proper tire-and-wheel combination.
Even though the two sizes are close in overall height, they are not the same fitment because the wheels themselves differ. That is why the buyer should identify the exact trim and then confirm the actual wheel size on the vehicle before selecting a replacement tire for normal road use.
Restoration & Appearance
Does correct tire fitment matter for a 2022 Cadillac Trucks XT5?
Yes, correct tire fitment matters on a 2022 Cadillac Trucks XT5 because the vehicle uses two distinct modern radial sizes tied to two different wheel diameters. Choosing between 235/65R18 and 235/55R20 is not just a styling decision; it affects whether the tire properly matches the wheel already on the vehicle.
Appearance still plays a role, especially on a premium crossover where wheel presentation is part of the overall look, but fitment comes first. A tire that matches the vehicle’s intended wheel package helps preserve the XT5’s stance and proportions while avoiding basic sizing mistakes during replacement.
How does tire size affect the appearance of a 2022 Cadillac Trucks XT5?
Tire size changes the visual relationship between the tire and wheel on a 2022 Cadillac Trucks XT5. The 235/65R18 fitment uses an 18-inch wheel with a taller sidewall, while the 235/55R20 fitment pairs a lower-profile tire with a 20-inch wheel for a different overall presentation.
That visual difference is one reason the XT5 has more than one fitment across its trims. Staying with the size intended for the wheel already on the vehicle usually maintains the look Cadillac designed into that configuration, while a mismatch can alter proportions even before any clearance issue appears.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Cadillac Trucks XT5?
Yes, modifications can affect tire fitment on a 2022 Cadillac Trucks XT5. If the vehicle has aftermarket wheels, suspension changes, or altered ride height, the original relationship between wheel diameter, tire size, and available clearance may no longer match the standard 235/65R18 or 235/55R20 setup.
A modified XT5 should be checked for wheel diameter, wheel width, and clearance at the fenders and steering components before new tires are selected. That extra step matters most on used vehicles, where the current setup may differ from the trim’s original configuration even if the tire size looks familiar.
What should I inspect before driving a 2022 Cadillac Trucks XT5 on new tires?
Before driving a 2022 Cadillac Trucks XT5 on new tires, inspect the wheels for the correct diameter, confirm the tire size matches the vehicle’s setup, and make sure inflation is set properly. It is also worth checking for any obvious suspension wear, uneven old tire wear patterns, or damage that could affect the new tires.
A short follow-up inspection after initial road use is a smart habit as well. Looking for rubbing, unusual vibration, or signs of irregular wear helps catch wheel-balance or fitment issues early, especially on an XT5 that may have had wheel changes or curb damage before the new tires were installed.
How often should tires on a 2022 Cadillac Trucks XT5 be inspected?
Tires on a 2022 Cadillac Trucks XT5 should be inspected regularly rather than waiting for a visible problem. A routine check of tread condition, air pressure, cuts, bulges, and sidewall damage is especially useful on a modern crossover that may see daily commuting, highway use, or long stretches between service visits.
It also helps to inspect the tires before longer trips and anytime the vehicle begins to pull, vibrate, or wear tires unevenly. Catching those signs early can point to inflation, alignment, or suspension issues before they shorten tire life or create a fitment concern around the XT5’s wheel-and-tire package.
