The 2024 GMC Trucks Yukon XL is a full-size SUV built around long-wheelbase utility, family hauling, and highway comfort, with enough trim variation to shift the tire conversation from simple replacement to exact configuration matching. On this vehicle, tire fitment centers on three radial sizes: 265/65R18, 275/60R20, and 275/50R22. Those sizes reflect different wheel packages across the Yukon XL lineup, so identifying the exact sub-model and wheel diameter comes first. Once that is confirmed, the decision usually comes down to preserving the intended stance and proportions of the vehicle while selecting the right tire for everyday road use, appearance, and wheel compatibility.
Which Tire Size Is Right for The 2024 GMC Trucks Yukon XL
The 2024 GMC Trucks Yukon XL uses three primary tire sizes, and the correct choice depends on the exact sub-model and wheel package. All three are radial fitments, but they do not share the same rim diameter, so the first step is confirming whether the vehicle is equipped with 18-inch, 20-inch, or 22-inch wheels before comparing tire options.
A 275/60R20 tire uses a 275-millimeter section width, a 60-series aspect ratio, radial construction, and a 20-inch rim. On the 2024 GMC Trucks Yukon XL, this size is one of the core fitments and appears across several sub-models, making it a common replacement point for owners with 20-inch wheels. Its dimensions place it close to the larger-wheel alternatives in overall height while keeping the proper 20-inch wheel requirement. This size is the right one to evaluate when the Yukon XL is equipped with the 20-inch setup and the goal is to maintain the intended fitment profile.
A 275/50R22 tire keeps the same 275-millimeter nominal width as the 20-inch option, but it uses a shorter 50-series sidewall to fit a 22-inch rim. For the 2024 GMC Trucks Yukon XL, this size is tied to trims and wheel packages that use the larger 22-inch wheel diameter. The format gives owners a straightforward modern radial sizing convention, but the wheel diameter difference means it should never be chosen by appearance alone. This is the size to consider when the vehicle already has 22-inch wheels and the tire selection needs to match that larger factory-style package.
A 265/65R18 tire combines a 265-millimeter section width with a 65-series aspect ratio and radial construction for an 18-inch rim. On the 2024 GMC Trucks Yukon XL, this size is a sub-model-specific fitment rather than a universal choice across the range. Compared with the other Yukon XL sizes, it uses a different wheel diameter and a slightly narrower nominal width, so wheel confirmation is essential before replacement. This size makes sense only when the vehicle is actually equipped with the 18-inch setup, especially on trims where multiple wheel and tire packages may appear.
Tire fitment on the 2024 GMC Trucks Yukon XL varies by sub-model, and some trims can be found with more than one factory-style size. Checking the exact trim and wheel diameter is the key step before choosing a replacement tire.

2024 GMC Trucks Yukon XL AT4
The 2024 GMC Trucks Yukon XL AT4 uses the 275/60R20 radial tire size. That makes the tire decision more straightforward, with the main focus shifting to confirming the 20-inch wheel setup and selecting a tire that preserves the intended fitment.
The 2024 GMC Trucks Yukon XL Denali can use either 275/50R22 or 275/60R20, depending on the wheel package installed on the vehicle. Tire selection starts with verifying whether the Yukon XL carries 20-inch or 22-inch wheels, since the two sizes are not interchangeable across rim diameters.
The 2024 GMC Trucks Yukon XL Denali Ultimate uses the 275/50R22 radial size. That keeps fitment focused on the 22-inch wheel package, so replacement shopping is mainly about matching the correct size and maintaining proper wheel compatibility.
The 2024 GMC Trucks Yukon XL SLE has the widest fitment spread in the lineup, with 265/65R18, 275/60R20, and 275/50R22 all appearing depending on configuration. On this trim, confirming the actual wheel diameter on the vehicle matters more than trim name alone before any replacement tire is chosen.
The 2024 GMC Trucks Yukon XL SLT uses either 275/60R20 or 275/50R22. The practical question is not which tire looks close, but which wheel diameter the SUV actually has, since the correct replacement must match that 20-inch or 22-inch 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
Owners shopping tires for a 2024 GMC Trucks Yukon XL usually need to sort out size, trim-specific wheel diameter, and the practical differences between the 18-inch, 20-inch, and 22-inch fitments before moving on to replacement selection and road-use checks.
Tire Size & Fitment
What tire size fits a 2024 GMC Trucks Yukon XL?
The 2024 GMC Trucks Yukon XL uses three radial tire sizes: 265/65R18, 275/60R20, and 275/50R22. The correct size depends on the exact sub-model and, just as importantly, the wheel package installed on the vehicle, since these sizes correspond to three different rim diameters.
The practical first step is checking the wheel itself before shopping for tires. A Yukon XL with 18-inch wheels needs 265/65R18, a 20-inch setup uses 275/60R20, and a 22-inch setup uses 275/50R22. Trim names help narrow the fitment, but the actual wheel diameter on the SUV is the final confirmation.
What size rim does a 2024 GMC Trucks Yukon XL use?
A 2024 GMC Trucks Yukon XL can use 18-inch, 20-inch, or 22-inch rims, depending on the sub-model and wheel package. Those rim diameters correspond to 265/65R18, 275/60R20, and 275/50R22 tire sizes, all in radial construction.
That matters because tire sizing is tied directly to rim diameter, not just overall vehicle model. A 20-inch tire cannot be mounted on a 22-inch wheel, and a 22-inch tire cannot be used on an 18-inch wheel. Verifying the wheel diameter stamped on the wheel or checking the current tire sidewall helps prevent ordering the wrong size.
Do all 2024 GMC Trucks Yukon XL sub-models use the same tire size?
No. The 2024 GMC Trucks Yukon XL lineup uses more than one tire size, and fitment changes by sub-model. AT4 uses 275/60R20, Denali Ultimate uses 275/50R22, while SLE, SLT, and Denali can appear with more than one size depending on wheel package.
That means the trim badge alone is not always enough to choose tires. On SLE, SLT, and Denali models, the safest approach is to confirm the size currently mounted on the vehicle and match it to the wheel diameter. This avoids confusion between 18-inch, 20-inch, and 22-inch setups that may all exist within the same broader model line.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 GMC Trucks Yukon XL?
Start with the exact tire size and wheel diameter already on the vehicle: 265/65R18, 275/60R20, or 275/50R22. All three are radial sizes, so the main selection issue is not construction type but matching the Yukon XL's specific wheel package and intended use.
After confirming size, compare how the SUV is actually used. A daily-driven family hauler, a tow vehicle, and a long-trip highway cruiser may all lead an owner to prioritize different tire characteristics. Wheel width, load needs, ride expectations, and any aftermarket wheel changes should be checked before choosing among replacement options in the correct size.
How do I choose between the available Yukon XL tire sizes if my trim offered more than one?
The right choice is the size that matches the wheel diameter installed on the vehicle. On a 2024 GMC Trucks Yukon XL, trims such as SLE, SLT, and Denali can appear with more than one tire size, but each size is tied to a specific 18-inch, 20-inch, or 22-inch wheel.
That means the decision is made by hardware, not preference alone. A larger or smaller listed Yukon XL size may look close in overall proportions, yet it still requires the matching rim diameter. Checking the current sidewall marking and measuring the wheel before replacement keeps the fitment process simple and avoids selecting a tire for the wrong wheel package.
What rim-width specifications should I compare when choosing 2024 GMC Trucks Yukon XL tires?
Rim width should always be checked alongside tire size, even when the sidewall size is correct. A 2024 GMC Trucks Yukon XL may use 18-inch, 20-inch, or 22-inch wheels, and the replacement tire needs to be suitable for the actual wheel width as well as the wheel diameter.
This becomes especially important if the Yukon XL has aftermarket wheels or if a wheel has been replaced outside the original package. Matching only the sidewall size is not enough. Verifying the wheel width, confirming that it suits the tire's approved range, and checking clearance at steering lock help prevent avoidable fitment problems on a large SUV.
Restoration & Appearance
Does correct tire fitment matter for a 2024 GMC Trucks Yukon XL restoration or preservation project?
Yes. Even on a newer full-size SUV such as the 2024 GMC Trucks Yukon XL, correct tire fitment matters if the goal is to preserve the intended look, stance, and wheel-package character of the vehicle. The three Yukon XL sizes each pair with a specific rim diameter and visual proportion.
Owners keeping the vehicle close to its original presentation should match the installed wheel package rather than substituting a different diameter for appearance alone. Using the correct size helps maintain the relationship between sidewall height and wheel size, which is especially noticeable on trims that use either 20-inch or 22-inch factory-style setups.
How does tire size affect the appearance of a 2024 GMC Trucks Yukon XL?
Tire size has a clear effect on how a 2024 GMC Trucks Yukon XL sits visually, especially because the model uses 18-inch, 20-inch, and 22-inch wheel packages. A 275/50R22 presents a shorter sidewall around a larger wheel, while 275/60R20 and 265/65R18 create a taller sidewall look.
That difference is one reason trim-specific fitment matters beyond simple mounting. Choosing the correct size helps preserve the intended balance between wheel presence and tire sidewall. On a large SUV, even small changes in that relationship can alter the overall presentation, so matching the existing wheel package is the best starting point for appearance-minded owners.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 GMC Trucks Yukon XL?
Yes. Modifications can change tire fitment on a 2024 GMC Trucks Yukon XL even when the sidewall size appears correct. Aftermarket wheels, changes in wheel offset, suspension lifts or drops, and body or brake-package changes can all affect how 265/65R18, 275/60R20, or 275/50R22 tires sit on the vehicle.
That is why a modified Yukon XL should be checked as an individual setup before replacement. Wheel diameter is only the first step. Clearance at full steering lock, space around suspension components, and fender room under compression all matter. Any change from the original wheel package deserves a careful fitment review before road use.
What should I inspect before driving a 2024 GMC Trucks Yukon XL on new tires?
Before driving a 2024 GMC Trucks Yukon XL on new tires, confirm that the size matches the installed wheel package and inspect inflation, bead seating, lug torque, and visible clearance around the suspension and body. A quick visual check should also confirm that all four tires are the intended size for that setup.
Road use is the time to catch small issues before they become larger ones. Watching for rubbing during turns, rechecking tire pressure after installation, and paying attention to vibration or pull on the first drive are sensible steps. On a large SUV, even a minor fitment error becomes more noticeable once the vehicle is loaded or driven at speed.
How often should tires on a 2024 GMC Trucks Yukon XL be inspected?
Tires on a 2024 GMC Trucks Yukon XL should be inspected regularly, not only when replacement time arrives. Routine checks should include tread wear, air pressure, visible cuts, punctures, bulges, and sidewall damage, along with a look for uneven wear that may point to alignment or suspension issues.
Frequent inspection is especially worthwhile on a full-size SUV because weight, passenger load, and long-distance use can place higher demands on the tires. A quick monthly walkaround and an additional check before travel help catch problems early. It is also wise to inspect more closely anytime the vehicle has struck a pothole or curb.
