The 2007 GMC Trucks Yukon XL 1500 sits in the full-size SUV market as a long-wheelbase utility vehicle built to carry passengers, cargo, and road-trip duty with the presence and capability buyers expect from a Yukon. Tire selection matters more here than it does on a lighter collector car, because this model uses three different radial sizes depending on sub-model and wheel package: 265/70R17, 265/65R18, and 275/55R20. That means the first step is identifying the exact trim and wheel diameter, then comparing the available tire choices within the correct size. For an owner replacing tires today, the real priorities are load capability, wheel compatibility, and keeping the truck's stance and use in mind.
Which Tire Size Is Right for The 2007 GMC Trucks Yukon XL 1500
Three tire sizes apply to the 2007 GMC Trucks Yukon XL 1500, and the right one depends on the exact sub-model and wheel setup. These are all radial fitments, but they use three different rim diameters: 17, 18, and 20 inches. Before choosing a tire, confirm whether the vehicle is an SLE, SLT, or Denali and verify the wheel diameter currently on the truck, especially if wheels have ever been changed.
265/65R18 is a metric radial size in which 265 is the section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2007 GMC Trucks Yukon XL 1500, this size belongs to an 18-inch wheel package rather than the 17-inch or 20-inch alternatives used elsewhere in the range. It keeps the buyer in a modern metric sizing format that is familiar and straightforward to match to the correct wheel. This is the size to evaluate when the truck is equipped with 18-inch rims and the goal is to stay with the proper wheel-and-tire relationship.
275/55R20 is a metric radial size that uses a 275-millimeter section width, a 55-series profile, and a 20-inch rim diameter. Within the 2007 GMC Trucks Yukon XL 1500 range, this size serves the trucks equipped with 20-inch wheels and should be treated as a distinct fitment rather than a casual substitute for the 17-inch or 18-inch setups. Its lower-profile metric format gives the buyer a different wheel-package context than the taller-sidewall alternatives. This size deserves a careful wheel confirmation first, since the 20-inch rim is the key fitment difference.
265/70R17 is a metric radial size with a 265-millimeter section width, a 70-series aspect ratio, and a 17-inch wheel diameter. On the 2007 GMC Trucks Yukon XL 1500, this size is used on 17-inch wheel applications and is the one product-backed fitment in this range, with BFGoodrich All-Terrain T/A KO2 options featuring raised white letter sidewalls. Those choices also differ in load capacity and weight, which matters on a full-size SUV used for carrying people or gear. This is the size to focus on when the truck has 17-inch wheels and the owner wants to compare available all-terrain-style options.
Sub-model fitment is not the same across the 2007 GMC Trucks Yukon XL 1500 range. Tire choice depends on identifying whether the truck is a Denali, SLE, or SLT and then confirming the wheel diameter currently installed.

2007 GMC Trucks Yukon XL 1500 Denali
The 2007 GMC Trucks Yukon XL 1500 Denali uses two radial tire fitments: 265/65R18 and 275/55R20. That makes wheel-diameter confirmation the first step, especially on a truck that may have changed wheels over time.
The 2007 GMC Trucks Yukon XL 1500 SLE uses the 265/70R17 radial size. Tire selection here is more straightforward, so the focus shifts from identifying the right size to comparing load capacity, rim-width compatibility, and tread style within that fitment.
The 2007 GMC Trucks Yukon XL 1500 SLT can use either 265/70R17 or 275/55R20, depending on the wheel package. Choosing correctly starts with the actual wheel diameter on the vehicle, then moves to selecting a tire that suits the truck's intended road use.
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.

Available product coverage in this fitment centers on 265/70R17, with BFGoodrich All-Terrain T/A KO2 choices in raised white letter styling. The main differences to compare are load capacity, weight, and the shared 7.0 to 9.0 inch rim-width specification.
Owners of a 2007 GMC Trucks Yukon XL 1500 usually need to sort out the correct tire size by sub-model and wheel diameter first. From there, the important questions turn to rim fitment, available tire choices, modifications, and pre-drive inspection.
Tire Size & Fitment
What tire size fits a 2007 GMC Trucks Yukon XL 1500?
The 2007 GMC Trucks Yukon XL 1500 uses three radial tire sizes: 265/70R17, 265/65R18, and 275/55R20. The correct size depends on the sub-model and wheel package. SLE uses 265/70R17, Denali uses 265/65R18 or 275/55R20, and SLT uses 265/70R17 or 275/55R20.
That makes the first decision simple but important: identify the exact trim and confirm the wheel diameter on the truck now. A Yukon XL 1500 that has had wheel changes over the years may no longer match its original setup, so checking the sidewall and measuring the wheel before replacement helps avoid choosing the right size for the wrong rim.
What size rim does a 2007 GMC Trucks Yukon XL 1500 use?
A 2007 GMC Trucks Yukon XL 1500 can use 17-inch, 18-inch, or 20-inch rims depending on sub-model and wheel package. The associated tire sizes are 265/70R17 for 17-inch rims, 265/65R18 for 18-inch rims, and 275/55R20 for 20-inch rims.
Wheel diameter is the key fitment checkpoint on this vehicle because the tire sizes are tied directly to different rim sizes. Looking only at the overall tire shape is not enough. Confirm the wheel diameter stamped on the rim or read the current tire sidewall, then match the replacement tire to that wheel before comparing tread type, load rating, or brand.
Why does the 2007 GMC Trucks Yukon XL 1500 have more than one tire size?
The 2007 GMC Trucks Yukon XL 1500 has more than one tire size because different sub-models and wheel packages were equipped with different rim diameters. SLE uses a 17-inch setup, Denali uses 18-inch or 20-inch fitments, and SLT can use either 17-inch or 20-inch tires.
That means tire selection is not just a year-make-model question on this truck. A buyer needs to know the specific trim and verify the actual wheels on the vehicle, especially if it has been upgraded or modified. Once that is confirmed, the correct size becomes much easier to narrow down and compare within the proper rim diameter.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2007 GMC Trucks Yukon XL 1500?
Start with the basics that matter most on a full-size SUV: correct size, radial construction, and wheel compatibility. In 265/70R17, the available BFGoodrich All-Terrain T/A KO2 choices share the same size and raised white letter appearance, but they differ in load capacity, inflation basis for that load, and tire weight.
Those details matter because a Yukon XL 1500 may see family use, cargo duty, or longer highway driving where load support is part of the buying decision. Compare the tire's intended use with the truck's real-world demands, and make sure the wheel falls within the stated 7.0 to 9.0 inch rim-width range before settling on a specific version.
What sidewall styles are available for 2007 GMC Trucks Yukon XL 1500 tires?
Among the currently covered product options for this fitment, 265/70R17 is available with an RWL sidewall, meaning raised white letters. That gives the Yukon XL 1500 a more traditional truck-oriented presentation than a plain black sidewall and can noticeably affect the vehicle's finished look.
Sidewall style is an appearance decision, but it should come after the correct size, construction, and wheel fitment are confirmed. On a truck like this, the sidewall treatment can either emphasize a utility look or keep things more understated. Buyers replacing one axle at a time should also think about how the new sidewall style will visually match the remaining tires.
What brands offer tires for the 2007 GMC Trucks Yukon XL 1500?
Current product coverage for the 2007 GMC Trucks Yukon XL 1500 includes BFGoodrich in 265/70R17. The available tire series is the All-Terrain T/A KO2, and it appears in more than one load version within that same size.
Brand is only one part of the choice. Once the right size is confirmed for the truck's wheel package, compare whether the available tire's load capacity, weight, and rim-width specification suit how the Yukon XL 1500 is actually used. On a long-wheelbase SUV, those practical details usually matter more than choosing by brand name alone.
Restoration & Appearance
Does correct tire fitment matter for a 2007 GMC Trucks Yukon XL 1500 restoration?
Yes. Correct tire fitment matters on a 2007 GMC Trucks Yukon XL 1500 because the truck uses different radial sizes tied to different wheel diameters and trim levels. Choosing the wrong size can change the vehicle's appearance and create an obvious mismatch between the tire, the wheel, and the stance of the SUV.
For a restoration-minded owner, the best starting point is matching the truck to the proper 17-inch, 18-inch, or 20-inch setup before worrying about tread pattern or sidewall details. If originality is especially important, compare the current wheel-and-tire package against vehicle records, period sales material, or marque-specific references rather than relying on appearance alone.
Which sidewall style suits a period-style 2007 GMC Trucks Yukon XL 1500?
A raised white letter sidewall can suit a period-style 2007 GMC Trucks Yukon XL 1500 if the goal is a truck-oriented appearance with a familiar late-2000s visual character. In the covered 265/70R17 product range, RWL is the sidewall treatment available, and it gives the tire a more expressive look than a plain black sidewall.
Appearance should still follow fitment, not lead it. Confirm the correct size and wheel diameter first, then decide whether the white-letter presentation fits the way the truck is being preserved or driven. A Yukon XL 1500 kept close to its original character may benefit from consistency across all four tires rather than mixing sidewall styles.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 GMC Trucks Yukon XL 1500?
Yes. Modifications can affect tire fitment on a 2007 GMC Trucks Yukon XL 1500 even when the tire size itself is correct for the model range. Aftermarket wheels, changes in wheel width, suspension lifts or lowering, and body or steering changes can alter clearance at the fender, suspension components, or full-lock turning points.
That is especially important on a vehicle that already has three possible rim diameters from the factory fitment range. A modified truck should be checked as an individual setup before replacement tires are chosen. Measure the existing wheel diameter, verify wheel width, and inspect for rubbing marks so the next tire matches the actual configuration, not just the badge on the tailgate.
What should I inspect before driving a 2007 GMC Trucks Yukon XL 1500 on new tires?
Check that the new tires match the correct size for the truck's wheel diameter, then inspect wheel condition, valve stems, and visible clearance around the suspension and fenders. Tire pressure should be set appropriately, and the sidewalls should be free from shipping damage, cuts, or mounting-related scuffs before the vehicle goes back into normal use.
A short initial road test is worthwhile on a Yukon XL 1500 because its size and weight can reveal vibration, pull, or clearance issues quickly. After the first drive, recheck air pressure and look for any signs of rubbing at full steering lock. Catching those issues early is better than assuming a correct size guarantees the whole setup is sorted.
What should I check before a longer drive in a 2007 GMC Trucks Yukon XL 1500?
Before a longer drive, confirm that all four tires are the correct size for the installed wheels and that inflation is consistent across the vehicle. Inspect tread and sidewalls for cuts, cracking, bulges, or uneven wear, and make sure there is no slow air loss that could become a larger problem once the truck is loaded and traveling at speed.
A long-wheelbase SUV places steady demands on its tires, so it is worth checking wheel-lug torque, visible clearance, and the condition of the spare as well. Pay extra attention if the Yukon XL 1500 has been sitting for extended periods or sees seasonal use. Low-use vehicles can look fine at a glance while still hiding age, flat-spotting, or pressure loss.
