The 2008 GMC Trucks Yukon XL 2500 sits in the heavy-duty end of the full-size SUV market, built for buyers who needed Suburban-sized passenger and cargo space with three-quarter-ton capability. That makes tire choice more than a styling decision, because this vehicle’s size, weight, and intended use place real importance on proper load support and wheel compatibility. The primary fitment is a 245/75R16 radial on a 16-inch rim, and both SLE and SLT models use that same size. Available choices in this fitment lean toward truck-oriented radial construction, so the key decision is selecting the right specification for towing, road use, and the actual wheel setup on the vehicle.
Which Tire Size Is Right for The 2008 GMC Trucks Yukon XL 2500
The 2008 GMC Trucks Yukon XL 2500 uses one primary tire size: 245/75R16, a radial fitment for a 16-inch rim. That size is shared across the covered SLE and SLT sub-models, so the main decision is not which primary size fits, but which radial tire specification best suits the vehicle’s load demands, wheel width, and intended use.
A 245/75R16 size uses a 245-millimeter nominal section width, a 75-series aspect ratio, radial construction, and a 16-inch rim diameter. On the 2008 GMC Trucks Yukon XL 2500, this is the standard radial fitment and it matches the vehicle’s heavy-duty full-size SUV role. Available choices in this size include BFGoodrich’s All-Terrain T/A KO2 with raised white letter sidewalls, giving the tire a more truck-focused appearance. It is the size to use when the vehicle still retains its original wheel diameter and the goal is to stay with the proper overall fitment category.
Tire fitment is straightforward across the covered 2008 GMC Trucks Yukon XL 2500 sub-models, because both use the same primary size. Checking the exact trim still matters as a good confirmation step before comparing tire specifications, wheel width requirements, and intended use.

2008 GMC Trucks Yukon XL 2500 SLE
The 2008 GMC Trucks Yukon XL 2500 SLE uses the same 245/75R16 radial fitment found across this model range. That keeps selection focused on choosing the right truck-oriented radial tire for the wheel setup, load needs, and whether the vehicle sees mostly highway driving, hauling, or mixed-use service.
The 2008 GMC Trucks Yukon XL 2500 SLT also uses the 245/75R16 radial tire size. With size fitment staying consistent, the practical choice becomes comparing tire specifications, sidewall presentation, and wheel-width compatibility rather than sorting through different primary tire sizes.
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 2008 GMC Trucks Yukon XL 2500?
The 2008 GMC Trucks Yukon XL 2500 uses a 245/75R16 radial tire. That is the primary fitment for both the SLE and SLT sub-models, so there is no split in tire size across the covered trims.
That consistency makes selection simpler, but the size alone is not the whole decision. It is still important to confirm that the vehicle has 16-inch wheels in the proper width range and that no aftermarket wheel or suspension changes have altered the fitment before choosing a replacement tire.
What size rim does a 2008 GMC Trucks Yukon XL 2500 use?
The primary tire fitment for the 2008 GMC Trucks Yukon XL 2500 is built around a 16-inch rim. In the available 245/75R16 product selection, the supported rim-width range is 6.5 to 8.0 inches, which gives a useful starting point when checking wheel compatibility.
Rim diameter needs to match the tire size exactly, and rim width matters as well on a heavy-duty SUV. A wheel that is too narrow, too wide, or not the intended diameter can affect tire shape, clearance, and load-carrying behavior, so verifying the actual wheels on the vehicle is worth doing before replacement.
Do all 2008 GMC Trucks Yukon XL 2500 sub-models use the same tire size?
Yes. The covered 2008 GMC Trucks Yukon XL 2500 sub-models use the same 245/75R16 radial tire size. Both the SLE and SLT versions share that primary fitment, so trim level does not create a different size requirement here.
That means the buying decision centers more on tire specification than on trim-specific sizing. Once the sub-model is confirmed, attention can shift to wheel width, intended use, sidewall style, and whether the SUV still has its original wheel and suspension setup or has been modified over time.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 2008 GMC Trucks Yukon XL 2500?
Start with the correct size, which is 245/75R16, and then look at construction, load capability, and wheel compatibility. The available radial option in this fitment carries a maximum load rating of 3,042 lbs at 80 psi and is intended for a 16-inch rim with a 6.5 to 8.0 inch width range.
A Yukon XL 2500 can see family use, cargo duty, towing, or mixed on-road driving, so the tire needs to match how the vehicle is actually used. Sidewall appearance also matters to some owners, and the current option uses raised white letters, which gives the SUV a more truck-oriented presentation.
What sidewall styles are available for 2008 GMC Trucks Yukon XL 2500 tires?
The current 245/75R16 product selection for the 2008 GMC Trucks Yukon XL 2500 includes an RWL sidewall, meaning raised white letter styling. That gives the tire a more traditional light-truck look than a plain black sidewall and can change the overall visual character of the SUV.
Sidewall style does not change the underlying size requirement, but it can affect how the vehicle looks once mounted. Buyers who want a more rugged or period truck presentation often pay close attention to this detail, especially on full-size SUVs that still retain factory-style wheels and trim.
What brands offer tires for the 2008 GMC Trucks Yukon XL 2500?
The available 245/75R16 fitment for the 2008 GMC Trucks Yukon XL 2500 currently includes a BFGoodrich option. It is offered in the All-Terrain T/A KO2 series, which is a truck-focused radial choice rather than a passenger-car-style touring tire.
Brand is only one part of the selection process. It still makes sense to compare the tire’s load rating, wheel-width compatibility, sidewall style, and how closely the tread character matches the way the Yukon XL 2500 is driven, whether that means daily road use, trail access, towing, or occasional hauling.
Restoration & Appearance
Which tire should I choose for a period-style 2008 GMC Trucks Yukon XL 2500?
A period-style approach for a 2008 GMC Trucks Yukon XL 2500 starts with the correct 245/75R16 radial size on a 16-inch wheel. Keeping the proper size preserves the SUV’s intended stance more effectively than chasing an oversized or undersized substitute that changes the visual balance.
Appearance then comes down to the tire’s overall character, including tread style and sidewall treatment. An RWL sidewall gives this fitment a distinctly truck-oriented look, while the final choice should still be guided by how original the vehicle remains and whether the goal is stock-style presentation or a more utility-focused stance.
Does correct tire fitment matter for a 2008 GMC Trucks Yukon XL 2500 restoration?
Yes, correct tire fitment matters because a large SUV like the 2008 GMC Trucks Yukon XL 2500 depends on the right size and wheel relationship for both appearance and function. The correct primary size is 245/75R16, and moving away from that can alter how the vehicle sits and fills the wheel openings.
Fitment also affects practical use, especially on a three-quarter-ton platform that may carry passengers, cargo, or towing loads. A restoration-minded owner should confirm the actual wheels on the vehicle, avoid assuming later modifications are harmless, and use period photos or model-specific references if exact appearance is especially important.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 GMC Trucks Yukon XL 2500?
Yes. Even though the primary size is 245/75R16, wheel swaps, suspension lifts, lowering changes, and altered offsets can all affect how that size sits on a 2008 GMC Trucks Yukon XL 2500. A modified vehicle may no longer behave like one that still has its original wheel and suspension relationship.
Checking the actual wheel diameter and width is the first step, followed by looking at steering clearance and space around the fenders and suspension. Those details matter on a full-size heavy-duty SUV, especially if the vehicle has seen aftermarket changes over the years or is used for towing and cargo duty.
What should I inspect before driving a 2008 GMC Trucks Yukon XL 2500 on new tires?
Before road use, inspect wheel condition, lug hardware, valve stems, and tire pressure, then confirm that all four tires are the correct 245/75R16 size. It also helps to look over the suspension and steering components, since worn parts can affect how a newly installed tire behaves.
A slow walkaround is worthwhile on a Yukon XL 2500 because this is a large, heavy vehicle that may sit unused for periods and then return to hauling duty. Pay attention to clearance at full steering lock, check for uneven ride height, and watch for vibration or pull during the first drive.
How often should tires on a 2008 GMC Trucks Yukon XL 2500 be inspected?
Tires on a 2008 GMC Trucks Yukon XL 2500 should be inspected regularly, not just when tread appears worn. Pressure, tread condition, sidewall damage, irregular wear, and signs of air loss are all worth checking often, especially on a vehicle that may carry heavy loads or spend time parked between uses.
Routine inspections matter because age, storage conditions, and underinflation can affect a tire long before it looks obviously worn. A quick monthly check is a sensible habit, and any vibration, pulling, cracking, bulge, or persistent pressure loss should be addressed before the SUV is used for highway travel or towing.
