The 2002 GMC Trucks Sierra 2500 HD came from a period when heavy-duty pickups were expected to handle real work yet still serve as everyday road vehicles. That makes tire selection more practical than cosmetic on this truck, especially if it still sees towing, hauling, or regular highway use. This Sierra 2500 HD uses a 245/75R16 radial tire on a 16-inch wheel, and that fitment stays consistent across the covered sub-models. Available choices in this size lean toward a modern all-terrain radial with raised white letter styling. The key is matching the truck's intended use with the correct size, wheel compatibility, and overall condition of the chassis and tires.
Which Tire Size Is Right for The 2002 GMC Trucks Sierra 2500 HD
The 2002 GMC Trucks Sierra 2500 HD uses one primary tire size: 245/75R16, a radial tire for a 16-inch rim. That same fitment carries across Base, SL, SLE, and SLT models, so the main decision is not which size fits, but which tire in that size best suits the truck's use, wheel width, and preferred appearance.
245/75R16 is a metric radial size in which 245 is the nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On the 2002 GMC Trucks Sierra 2500 HD, this is the primary road-use fitment and reflects the truck's heavy-duty pickup role. Available choices in this size include BFGoodrich's All Terrain TA KO2 with raised white letter sidewalls. This size is the right starting point for owners who want to keep the truck on its correct 16-inch fitment while evaluating load capacity, rim-width compatibility, and intended use.
Tire fitment is straightforward across the covered 2002 GMC Trucks Sierra 2500 HD sub-models because each one uses the same 245/75R16 radial size. Checking the exact trim still helps confirm that the truck has not been changed to a different wheel or tire package over time.

2002 GMC Trucks Sierra 2500 HD Base
The 2002 GMC Trucks Sierra 2500 HD Base uses the same 245/75R16 radial fitment as the other covered trims. That keeps tire selection focused on wheel-width compatibility, load needs, and whether the truck will spend more time on pavement, mixed use, or work duty.
The 2002 GMC Trucks Sierra 2500 HD SL also uses 245/75R16 radial tires on a 16-inch rim. For this sub-model, the practical choice is comparing available tires within that size rather than sorting through multiple original fitments.
The 2002 GMC Trucks Sierra 2500 HD SLE shares the same 245/75R16 radial tire size used across the covered Sierra 2500 HD lineup. That means the next step is choosing a tire whose construction, sidewall presentation, and service capability match how the truck is actually driven.
The 2002 GMC Trucks Sierra 2500 HD SLT uses the same 245/75R16 radial size as the other listed sub-models. Selection comes down to finding the right tire in that size for the truck's wheel setup, duty level, and desired look rather than picking between different primary fitments.
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 2002 GMC Trucks Sierra 2500 HD?
The 2002 GMC Trucks Sierra 2500 HD uses 245/75R16 tires. This is a radial fitment for a 16-inch wheel, and it is the primary tire size across the covered Base, SL, SLE, and SLT sub-models.
That consistency makes size selection simple, but the truck should still be checked carefully if it has been updated over the years. Aftermarket wheels, suspension changes, or a previous owner's tire swap can change what is currently on the truck, so confirm the actual wheel diameter and available clearance before replacing tires.
What size rim does a 2002 GMC Trucks Sierra 2500 HD use?
The primary tire fitment for the 2002 GMC Trucks Sierra 2500 HD is built around a 16-inch rim. The 245/75R16 size uses that 16-inch wheel diameter, and available products in this size include rim-width compatibility information that should be checked during selection.
Wheel diameter is only part of the fitment picture on a heavy-duty pickup. A truck can still have the correct 16-inch diameter but the wrong wheel width for a specific tire, so it helps to verify both dimensions before mounting a replacement, especially if the truck has seen work-truck service or aftermarket wheel changes.
Do all 2002 GMC Trucks Sierra 2500 HD sub-models use the same tire size?
The covered 2002 GMC Trucks Sierra 2500 HD Base, SL, SLE, and SLT sub-models all use the same 245/75R16 radial tire size. There is no split fitment among those listed trims, so the main fitment decision is not trim-specific size selection.
Even with shared trim-level fitment, it is still smart to inspect the truck before ordering replacements. A Sierra 2500 HD that has been lifted, lowered, fitted with aftermarket wheels, or changed for commercial use may need extra attention to wheel width, tire clearance, and current load demands.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 2002 GMC Trucks Sierra 2500 HD?
Start with the correct size, 245/75R16, then compare construction, load specification, and wheel compatibility. On a truck like the 2002 GMC Trucks Sierra 2500 HD, those factors matter more than appearance alone because the tire may be asked to support hauling, towing, or regular highway miles.
It also helps to match the tire to the truck's real use. A more road-focused setup may prioritize steady highway manners, while a work or mixed-surface truck may benefit from an all-terrain design, provided the wheel width, tire rating, and overall clearance remain appropriate for the vehicle's actual setup.
What sidewall styles are available for 2002 GMC Trucks Sierra 2500 HD tires?
Available 245/75R16 product choices for the 2002 GMC Trucks Sierra 2500 HD include an RWL sidewall, meaning raised white letter styling. That gives the truck a more traditional light-truck appearance than a plain blackwall while staying within the correct size and radial construction.
Sidewall style changes the look of the truck more than the fitment itself, so it should be treated as a secondary decision after confirming size and wheel specs. Owners who want a cleaner utility look may prefer more understated tires when available, while raised white letters suit a more period-truck presentation.
What brands offer tires for the 2002 GMC Trucks Sierra 2500 HD?
Current 245/75R16 fitment choices for the 2002 GMC Trucks Sierra 2500 HD include BFGoodrich. In this size, the available offering is the All Terrain TA KO2, a radial all-terrain tire with raised white letter sidewall styling.
Brand should be considered alongside the tire's actual specifications rather than by name alone. On a heavy-duty Sierra, compare the product's intended use, rim-width compatibility, and load figure with how the truck is driven, especially if it sees trailer duty, jobsite travel, or long highway runs.
Restoration & Appearance
Which tire should I choose for a period-style 2002 GMC Trucks Sierra 2500 HD?
A period-style approach for a 2002 GMC Trucks Sierra 2500 HD starts with keeping the correct 245/75R16 radial fitment on a 16-inch wheel. That preserves the truck's original sizing direction while leaving room to choose a tread and sidewall presentation that suits an early-2000s heavy-duty pickup.
Appearance decisions should follow fitment, not replace it. A truck meant to look true to its era may benefit from a traditional light-truck sidewall treatment such as raised white letters, but owners pursuing exact originality should still compare against vehicle-specific documentation and the truck's actual wheel setup.
How does tire construction affect the appearance of a restored 2002 GMC Trucks Sierra 2500 HD?
On a 2002 GMC Trucks Sierra 2500 HD, the primary fitment is already radial, so construction changes are less about vintage bias-ply character and more about choosing the right modern truck-tire look. The visual difference often comes from tread style and sidewall treatment rather than from construction type alone.
That means restoration-minded owners should pay attention to proportion, stance, and sidewall presentation once the correct 245/75R16 size is confirmed. A tire with an aggressive all-terrain tread and raised white letters creates a different impression than a simpler highway-style radial, even though both may share the same basic fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2002 GMC Trucks Sierra 2500 HD?
Yes, modifications can affect tire fitment on a 2002 GMC Trucks Sierra 2500 HD even when the original size is 245/75R16. Changes such as aftermarket wheels, altered wheel offset, suspension lifts, lowering kits, or body modifications can all influence clearance and how the tire sits in the wheel opening.
A truck that has been changed from stock should be measured before replacement tires are chosen. Checking wheel diameter, wheel width, steering clearance, and suspension travel is especially important on a heavy-duty pickup, because a setup that clears at rest can still create rubbing issues under load or during turning.
What should I inspect before driving a 2002 GMC Trucks Sierra 2500 HD on new tires?
Before driving a 2002 GMC Trucks Sierra 2500 HD on new tires, inspect the wheels, valve stems, lug hardware, and the condition of the suspension and steering components. Tire pressure should be set correctly for the application, and the tires should be checked for proper seating, visible damage, and any immediate air loss.
A short test drive followed by a second inspection is a smart step on a truck that may carry weight or see highway duty. Recheck inflation, watch for vibration or rubbing, and make sure the tire clears through full steering travel, especially if the Sierra has non-stock wheels or a changed ride height.
How should 245/75R16 tires on a 2002 GMC Trucks Sierra 2500 HD be maintained?
245/75R16 tires on a 2002 GMC Trucks Sierra 2500 HD should be maintained with regular pressure checks, visual inspections, and attention to uneven wear. Sidewall cuts, cracking, punctures, tread damage, and slow air loss matter on any vehicle, but they are especially important on a heavy-duty truck that may be carrying substantial loads.
Consistent maintenance also means watching the truck itself, not just the tire. Alignment problems, worn suspension parts, overloaded use, or long periods of storage can all shorten tire life, so it helps to inspect the full wheel-and-tire setup routinely and before longer trips or work-related driving.
