The 2017 GMC Trucks Yukon XL sits in the full-size SUV class with the long-wheelbase proportions, passenger room, and cargo capacity that make these trucks a common choice for family hauling, towing, and road-trip duty. Tire selection matters because this Yukon XL uses three different radial fitments depending on configuration: 265/65R18, 275/55R20, and 285/45R22. That gives owners a choice not just in brand, but in wheel diameter and overall tire presentation. The right starting point is confirming the exact sub-model and wheel setup, then choosing a tire that matches how the vehicle is actually used on the road.
Which Tire Size Is Right for The 2017 GMC Trucks Yukon XL
The 2017 GMC Trucks Yukon XL uses three primary tire sizes, and the correct one depends first on the exact sub-model and wheel diameter. All three are radial metric sizes, but they correspond to different 18-inch, 20-inch, and 22-inch wheel setups, so confirming the wheel currently on the vehicle is the key first step before comparing replacement tires.
A 275/55R20 tire is a metric radial size in which 275 identifies nominal section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 20 is the required rim diameter in inches. On the 2017 GMC Trucks Yukon XL, this size represents one of the primary full-size SUV fitments and balances modern sizing with a substantial sidewall. Its dimensions place it close to the other Yukon XL fitments in overall height, but it belongs on a 20-inch wheel. This size makes sense when the vehicle is already equipped with the corresponding 20-inch setup and clearance remains stock or properly verified.
A 285/45R22 tire uses the same metric radial naming format, with 285 indicating nominal width in millimeters, 45 indicating the profile, and 22 identifying the wheel diameter. For the 2017 GMC Trucks Yukon XL, this fitment is tied to a larger-diameter wheel and a shorter sidewall appearance than the 18-inch and 20-inch alternatives. It is still a primary radial fitment, but it should not be treated as interchangeable with the other sizes without matching the wheel diameter. This size is the one to evaluate when the vehicle has a 22-inch wheel package and the goal is to preserve that stance and presentation.
A 265/65R18 tire is a metric radial size where 265 is the nominal section width in millimeters, 65 is the aspect ratio, and 18 is the rim diameter in inches. On the 2017 GMC Trucks Yukon XL, this is the 18-inch primary fitment and carries the tallest sidewall profile of the three stock size formats used here. That makes wheel confirmation especially important, since an 18-inch tire cannot be mounted on the 20-inch or 22-inch wheel setups used elsewhere in the Yukon XL range. It is the right size to compare when the vehicle retains its 18-inch wheel configuration.
Sub-model fitment on the 2017 GMC Trucks Yukon XL is not completely uniform, so identifying the exact trim and wheel package matters before choosing tires. The main distinction is whether the vehicle uses the 18-inch, 20-inch, or 22-inch setup tied to its current configuration.

2017 GMC Trucks Yukon XL Denali
The 2017 GMC Trucks Yukon XL Denali uses either 275/55R20 or 285/45R22 radial tires. Tire selection starts with confirming whether the Denali is on its 20-inch or 22-inch wheels, then choosing within that size rather than assuming both options apply to the same wheel.
The 2017 GMC Trucks Yukon XL SLE can use 265/65R18, 275/55R20, or 285/45R22 radial tires depending on wheel setup. That makes wheel diameter the critical checkpoint before replacement, especially on vehicles that may have changed wheels since new.
The 2017 GMC Trucks Yukon XL SLT also spans 265/65R18, 275/55R20, and 285/45R22 radial fitments. The practical decision is confirming the actual wheel on the vehicle first, then comparing tires within the correct size for road use, load needs, and overall appearance.
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 2017 GMC Trucks Yukon XL usually center on identifying the correct tire size by sub-model and wheel diameter, then understanding how those 18-inch, 20-inch, and 22-inch radial fitments affect replacement choices, maintenance, and day-to-day road use.
Tire Size & Fitment
What tire size fits a 2017 GMC Trucks Yukon XL?
The 2017 GMC Trucks Yukon XL uses three primary tire sizes: 265/65R18, 275/55R20, and 285/45R22. All three are radial fitments, but they do not apply universally across every Yukon XL in the same way because the correct tire depends on the vehicle's specific sub-model and wheel diameter.
The most important step is confirming the wheel currently on the SUV before choosing a replacement tire. An 18-inch tire belongs on an 18-inch wheel, a 20-inch tire on a 20-inch wheel, and a 22-inch tire on a 22-inch wheel, so the actual wheel setup matters more than assuming one size fits every Yukon XL.
What size rim does a 2017 GMC Trucks Yukon XL use?
A 2017 GMC Trucks Yukon XL can use 18-inch, 20-inch, or 22-inch rims, depending on the tire size installed. The three corresponding fitments are 265/65R18 on an 18-inch rim, 275/55R20 on a 20-inch rim, and 285/45R22 on a 22-inch rim.
Rim diameter should be checked before anything else because it determines which tire size family the vehicle can use. Measuring the wheel or reading the size on the current tire is a practical starting point, especially on used Yukon XL models that may have had wheel upgrades or replacements at some point in their service life.
Do all 2017 GMC Trucks Yukon XL sub-models use the same tire size?
No, the 2017 GMC Trucks Yukon XL sub-models do not all use the same tire size. Denali uses 275/55R20 or 285/45R22, while SLE and SLT can use 265/65R18, 275/55R20, or 285/45R22 depending on their wheel setup.
That means trim name alone is helpful, but it is still not the only thing to verify. The vehicle's actual wheel diameter matters just as much, since many Yukon XL models can appear similar at a glance while using different wheel-and-tire packages that require different replacement sizes.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 GMC Trucks Yukon XL?
Start with the correct size for the vehicle's actual wheel setup: 265/65R18, 275/55R20, or 285/45R22. On a 2017 GMC Trucks Yukon XL, size selection comes before any other decision because the SUV uses multiple rim diameters across its sub-model range.
After size is confirmed, compare the tire's intended use with how the Yukon XL is driven. A family hauler, highway cruiser, or tow vehicle may place different demands on ride quality, load support, and tread design, so wheel compatibility, overall condition of the suspension, and clearance at full steering lock are all worth checking.
How do I choose between the available 2017 GMC Trucks Yukon XL tire sizes?
The correct size is chosen by the wheel already on the vehicle, not by preference alone. A 2017 GMC Trucks Yukon XL using 18-inch wheels takes 265/65R18, a 20-inch setup takes 275/55R20, and a 22-inch setup takes 285/45R22.
That makes this less about picking among three interchangeable sizes and more about matching the tire to the existing wheel package. If the Yukon XL has aftermarket wheels or a previous owner changed the setup, verify the wheel diameter and make sure the replacement tire maintains proper clearance before mounting a new set.
What rim-width specifications should I compare when choosing 2017 GMC Trucks Yukon XL tires?
Rim width matters because a tire must be supported by a wheel that suits its size and intended profile. On a 2017 GMC Trucks Yukon XL, that question becomes especially important when replacing worn tires on wheels that may not be original to the vehicle.
The practical approach is to confirm both wheel diameter and actual wheel width before selecting a new tire, particularly on 20-inch and 22-inch setups. That helps avoid a mismatch in sidewall shape or fitment and gives a clearer picture of how the new tire will sit in the wheel opening and steer under load.
Restoration & Appearance
Does correct tire fitment matter for a 2017 GMC Trucks Yukon XL restoration?
Yes, correct tire fitment still matters on a 2017 GMC Trucks Yukon XL, even though it is a much newer vehicle than a traditional collector car. Using the proper 18-inch, 20-inch, or 22-inch size helps preserve the vehicle's intended stance, wheel-to-tire proportion, and overall presentation.
Appearance is only part of the equation, though. A Yukon XL that is being refreshed, preserved, or kept close to its original character should also retain a size that matches the wheel package actually on the vehicle, since changing tire size without confirming wheel specs can alter both how it looks and how it sits.
How does tire size affect the appearance of a 2017 GMC Trucks Yukon XL?
Tire size has a noticeable effect on how a 2017 GMC Trucks Yukon XL presents itself because the vehicle can use 18-inch, 20-inch, or 22-inch wheel-and-tire packages. The 265/65R18 carries a taller sidewall look, while the 285/45R22 gives a larger-wheel, shorter-sidewall appearance.
That visual difference matters when replacing only two tires or trying to maintain a consistent look across the entire vehicle. Matching the existing size keeps the proportions intact, while any wheel or tire change should be checked carefully so the Yukon XL still has the appearance and clearance the owner expects.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 GMC Trucks Yukon XL?
Yes, modifications can affect tire fitment on a 2017 GMC Trucks Yukon XL. Wheel changes, suspension alterations, leveling kits, lowering, or body-trim adjustments can all influence how a 265/65R18, 275/55R20, or 285/45R22 tire sits and clears during steering and suspension movement.
A Yukon XL with aftermarket wheels should be checked for actual wheel diameter, width, and clearance before a replacement tire is chosen. Even when the size on the sidewall looks familiar, the total setup may differ from stock enough to change how the tire behaves near the fender, suspension, or steering components.
What should I inspect before driving a 2017 GMC Trucks Yukon XL on new tires?
Before driving a 2017 GMC Trucks Yukon XL on new tires, inspect the wheel condition, valve stems, lug hardware, and inflation pressure, then confirm the tire size matches the wheel diameter. It also makes sense to look over the suspension and steering components so the new tires are not being asked to work around existing wear.
A short clearance check is worthwhile before regular use, especially if the vehicle has 22-inch wheels or any non-stock setup. Turning the steering from lock to lock and watching for rubbing can catch problems early, while a quick road test can reveal vibration, pull, or other signs that the tires or wheels need attention.
How often should tires on a 2017 GMC Trucks Yukon XL be inspected?
Tires on a 2017 GMC Trucks Yukon XL should be inspected regularly rather than only when tread looks low. A visual check for uneven wear, cuts, cracking, bulges, and air loss is a smart habit on any full-size SUV, especially one that may carry passengers, cargo, or towing loads.
Routine pressure checks and periodic close inspection become even more important when the Yukon XL spends time parked or sees seasonal use. Catching a wear pattern early can point to alignment or suspension issues, and spotting age-related damage before a trip helps prevent a small problem from turning into a roadside interruption.
