The 2010 GMC Trucks Yukon XL 1500 sits squarely in the era of full-size SUVs built to carry people, cargo, and long-distance road miles without giving up truck-based capability. Its extended-wheelbase layout makes tire selection more than a cosmetic choice, because the right size affects stance, ride, and everyday usefulness. This Yukon XL 1500 uses radial tires, but fitment varies by sub-model and wheel package across 17-, 18-, and 20-inch rims. That means the decision starts with identifying the exact trim and wheel diameter, then narrowing down the right tire style within that size. Owners should also confirm the current wheel setup before replacing tires on a used or modified truck.
Which Tire Size Is Right for The 2010 GMC Trucks Yukon XL 1500
Three primary tire sizes apply to the 2010 GMC Trucks Yukon XL 1500, and they differ by sub-model and wheel diameter rather than by old-style bias-ply versus radial construction. The first step is confirming the exact trim and whether the truck is on 17-, 18-, or 20-inch wheels, because each size is tied to a specific rim diameter. Once that is settled, the remaining decision is choosing the right product within the correct size for the truck's intended use and appearance.
275/55R20 is a metric radial size in which 275 represents the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2010 GMC Trucks Yukon XL 1500, this size belongs to 20-inch wheel applications and is the fitment used on the Denali as well as certain SLE and SLT configurations. Its role in the lineup makes wheel confirmation especially important on used SUVs that may have changed hands or been upgraded. Choose this size only after verifying that the truck is actually equipped with 20-inch rims.
265/70R17 is a metric radial size, with 265 indicating section width in millimeters, 70 showing the aspect ratio, and 17 identifying the rim diameter. For the 2010 GMC Trucks Yukon XL 1500, this size is used on certain SLE and SLT models fitted with 17-inch wheels. Available products in this size include BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls and differing load capacities, giving buyers a more truck-oriented choice within the correct fitment. It is a useful size to evaluate when the Yukon XL is expected to handle heavier-duty road or mixed-use driving.
265/65R18 follows the same metric radial sizing system, with 265 as the section width in millimeters, 65 as the aspect ratio, and 18 as the wheel diameter. On the 2010 GMC Trucks Yukon XL 1500, this size is tied to the SLE XFE configuration, so trim identification matters before selecting a replacement. Its dimensions place it close to the other primary sizes in overall diameter, but the 18-inch rim requirement means it cannot be chosen on wheel diameter alone by appearance. Buyers should confirm the truck's exact sub-model and current wheels before moving ahead with this fitment.
Sub-model fitment matters on the 2010 GMC Trucks Yukon XL 1500 because tire size changes with trim and wheel package. Some versions share the same size options, while others use one specific size tied to a different rim diameter.

2010 GMC Trucks Yukon XL 1500 Denali
The 2010 GMC Trucks Yukon XL 1500 Denali uses the 275/55R20 radial tire size. Tire selection for this sub-model starts with keeping the 20-inch wheel fitment intact, then choosing the right replacement tire style and service characteristics for how the SUV is driven.
The 2010 GMC Trucks Yukon XL 1500 SLE can use either a 265/70R17 or 275/55R20 radial tire, depending on the wheel setup. That makes it especially important to check the actual rim diameter on the vehicle before choosing a replacement, particularly if the truck has seen wheel changes over time.
The 2010 GMC Trucks Yukon XL 1500 SLE XFE uses the 265/65R18 radial tire size. Tire selection here is straightforward once the 18-inch wheel fitment is confirmed, and the main task becomes matching the correct size to the vehicle's present wheel and road-use setup.
The 2010 GMC Trucks Yukon XL 1500 SLT can use either 265/70R17 or 275/55R20 radial tires depending on its wheel package. Buyers should verify the wheel diameter on the truck rather than choosing by trim name alone, since the replacement size follows the actual rim in 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.

Tire Size & Fitment
What tire size fits a 2010 GMC Trucks Yukon XL 1500?
The 2010 GMC Trucks Yukon XL 1500 uses three primary tire sizes: 265/70R17, 265/65R18, and 275/55R20. All are radial tires, and the correct one depends on the sub-model and wheel package rather than a single universal fitment across the entire Yukon XL 1500 range.
The most important first step is confirming the actual wheel diameter on the truck. An SLE or SLT may use either 17-inch or 20-inch wheels, while the Denali uses 275/55R20 and the SLE XFE uses 265/65R18, so checking the trim badge alone is not always enough.
What size rim does a 2010 GMC Trucks Yukon XL 1500 use?
A 2010 GMC Trucks Yukon XL 1500 may use 17-inch, 18-inch, or 20-inch rims depending on the specific sub-model and wheel package. The matching tire sizes are 265/70R17 for 17-inch rims, 265/65R18 for 18-inch rims, and 275/55R20 for 20-inch rims.
Rim diameter is the key fitment checkpoint because the tire must match the wheel exactly. Before replacing tires, inspect the wheels currently on the SUV, especially if it has been bought used or may have aftermarket wheels, since trim names and present wheel equipment do not always match.
Do all 2010 GMC Trucks Yukon XL 1500 sub-models use the same tire size?
No, the 2010 GMC Trucks Yukon XL 1500 does not use one tire size across every sub-model. The Denali uses 275/55R20, the SLE XFE uses 265/65R18, and SLE and SLT models may use either 265/70R17 or 275/55R20 depending on how the vehicle was equipped.
That variation means tire selection starts with identifying both the exact sub-model and the wheel diameter actually on the SUV. A Yukon XL 1500 with replacement wheels or a previous wheel-package change can easily lead to ordering the wrong size unless the current setup is checked first.
Choosing the Right Tire
What should I consider when choosing a tire for a 2010 GMC Trucks Yukon XL 1500?
Start with the correct primary size for the SUV: 265/70R17, 265/65R18, or 275/55R20 depending on trim and wheel package. After that, compare the construction, service description, load capacity, rim-width compatibility, and the type of driving the Yukon XL 1500 will actually see.
A long-wheelbase SUV places real demands on tires, so replacement choice should reflect how the vehicle is used. A road-focused setup may call for a different tread character than a truck used for mixed pavement and utility work, and any selection should still match the wheel diameter and overall vehicle setup.
What sidewall styles are available for 2010 GMC Trucks Yukon XL 1500 tires?
Within the currently available Yukon XL 1500 products, the visible sidewall style offered in 265/70R17 is RWL, or raised white letter. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options available in this size.
Sidewall style affects appearance but should come after the correct size and wheel fitment are confirmed. On a full-size GMC SUV, raised white letters create a more truck-oriented presentation, but the buyer still needs to compare the tire's load specification, rim-width range, and intended use before making a final choice.
What brands offer tires for the 2010 GMC Trucks Yukon XL 1500?
BFGoodrich is represented among the currently available products for the 2010 GMC Trucks Yukon XL 1500, specifically in the 265/70R17 size. The available offering is the All-Terrain T/A KO2 series in radial construction with raised white letter sidewalls.
Brand matters only after confirming the correct size for the sub-model and wheel package. Once the fitment is settled, compare the actual tire specifications within that size, including load capacity, weight, sidewall presentation, and compatible rim-width range, since those details shape how suitable the tire is for the truck's use.
Restoration & Appearance
Which tire should I choose for a period-style 2010 GMC Trucks Yukon XL 1500?
A period-style approach on a 2010 GMC Trucks Yukon XL 1500 usually starts with keeping the correct original-format size for the specific trim and wheel package, whether that is 265/70R17, 265/65R18, or 275/55R20. Because this is a modern SUV, the correct radial size and wheel diameter matter more than chasing an older collector-style construction.
Appearance still plays a role, especially if the truck is being preserved in a stock-looking configuration. The cleanest result usually comes from matching the existing wheel setup and choosing a tread and sidewall treatment that suits the vehicle's character without changing proportions or creating an obviously mismatched stance.
Does correct tire fitment matter for a 2010 GMC Trucks Yukon XL 1500 restoration or preservation project?
Yes, correct tire fitment matters because the Yukon XL 1500 was offered with multiple wheel-and-tire combinations tied to different trims. Using the right size helps preserve the intended proportions of the SUV and keeps the wheel diameter aligned with the vehicle's existing configuration.
That is especially important on a preserved or lightly restored truck where visual balance matters as much as function. If exact presentation is a priority, compare the current wheels to the sub-model's proper size range and avoid assuming that any 17-, 18-, or 20-inch tire package will look equally appropriate.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 GMC Trucks Yukon XL 1500?
Yes, modifications can affect tire fitment on a 2010 GMC Trucks Yukon XL 1500 even when the basic tire size seems close to stock. Wheel changes, altered offset, suspension lifts or lowering, and body or fender modifications can all change the clearance available around a 265/70R17, 265/65R18, or 275/55R20 tire.
Any Yukon XL that has aftermarket wheels should be measured rather than judged by trim name alone. Tire replacement should account for the actual wheel diameter and width on the vehicle, along with steering clearance and space at the fenders, because a modified SUV may no longer match its original factory-type setup.
What should I inspect before driving a 2010 GMC Trucks Yukon XL 1500 on new tires?
Before road use, inspect the wheel diameter, lug hardware, valve stems, tire pressure, and overall tire condition to make sure the replacement set is ready for service. It also helps to confirm that the installed size matches the Yukon XL 1500's actual wheels and that there is no rubbing at full steering lock.
A large SUV can mask early fitment issues until it is loaded, turned sharply, or driven at highway speed. After installation, recheck for air loss, uneven seating, and any contact with suspension or body components, especially if the truck has non-stock wheels or has sat unused for extended periods.
How often should tires on a 2010 GMC Trucks Yukon XL 1500 be inspected?
Tires on a 2010 GMC Trucks Yukon XL 1500 should be inspected regularly, not just when tread appears low. Frequent checks for pressure loss, irregular wear, cracking, cuts, bulges, and embedded damage are especially important on a heavy full-size SUV that may carry passengers and cargo over long distances.
Routine inspection is even more important on a vehicle that sees seasonal use or spends long periods parked. Looking over the tires before longer trips helps catch age-related issues early, and it is a good time to confirm that the wheel-and-tire package still clears properly if the SUV has had wheel or suspension changes.
