The 2002 GMC Trucks Sierra 3500 sits in the heavy-duty end of the GMT800 pickup line, a truck built for serious payload, towing, and work-focused use while still carrying the familiar Sierra mix of utility and comfort. Tire choice matters here because the Sierra 3500 uses two different radial sizes depending on configuration: 245/75R16 on single-rear-wheel models and 225/75R16 on dual-rear-wheel front and rear positions. That means the first step is confirming whether the truck is a standard rear-wheel setup or a dually. From there, the decision shifts to matching the correct load-capable 16-inch tire to the truck's wheel setup and intended use.
Which Tire Size Is Right for The 2002 GMC Trucks Sierra 3500
The 2002 GMC Trucks Sierra 3500 uses two primary tire sizes, and the right one depends on the truck's exact configuration. Both are radial tires for 16-inch rims, but single-rear-wheel models use 245/75R16 while dual-rear-wheel front and rear positions use 225/75R16. Before choosing a tire, confirm whether the truck is a dually or a standard rear-wheel Sierra 3500.
245/75R16 is a metric radial size with a 245-millimeter nominal section width, a 75-series profile, radial construction, and a 16-inch rim diameter. On the 2002 GMC Trucks Sierra 3500, this size applies to single-rear-wheel Base, SL, SLE, and SLT models. The available product in this fitment is the BFGoodrich All-Terrain T/A KO2 with raised white letters, giving the truck a more aggressive light-truck appearance. This is the size to consider when the truck is not a dually and still retains the proper 16-inch wheel and compatible rim width.
Sub-model fitment on the 2002 GMC Trucks Sierra 3500 is tied mainly to rear-wheel configuration rather than trim level alone. Standard single-rear-wheel trims use one size, while dual-rear-wheel front and rear positions use another, so confirming the exact setup is the key first step.

2002 GMC Trucks Sierra 3500 (DRW) Front
The 2002 GMC Trucks Sierra 3500 (DRW) Front uses the narrower dually radial fitment rather than the single-rear-wheel size. Tire selection here should focus on matching the front dually wheel setup and confirming that the truck still carries the correct 16-inch front wheels.
The 2002 GMC Trucks Sierra 3500 (DRW) Rear uses the same 225/75R16 radial size as the front dually position. Rear dual-wheel spacing, wheel condition, and maintaining the proper dually setup matter just as much as choosing the correct tire size.
The 2002 GMC Trucks Sierra 3500 Base uses the larger single-rear-wheel radial fitment rather than the dually size. That makes tire choice more straightforward, with the focus shifting to load-capable 16-inch tires and wheel-width compatibility for 245/75R16.
The 2002 GMC Trucks Sierra 3500 SL uses the 245/75R16 radial size in standard single-rear-wheel form. Tire selection should stay centered on that 16-inch fitment unless the truck has been changed to a dually setup or fitted with aftermarket wheels.
The 2002 GMC Trucks Sierra 3500 SL (DRW) Front uses the 225/75R16 radial size associated with dually applications. Choosing correctly means confirming the front dual-rear-wheel configuration and avoiding the wider single-rear-wheel size used on non-DRW trims.
The 2002 GMC Trucks Sierra 3500 SL (DRW) Rear also uses 225/75R16, matching the dually arrangement rather than the standard rear-wheel setup. The important consideration is preserving proper rear dual-wheel compatibility, including wheel width and spacing.
The 2002 GMC Trucks Sierra 3500 SLE uses the 245/75R16 radial size in single-rear-wheel form. That keeps tire selection focused on the correct 16-inch wheel fitment and on choosing a tire that matches the truck's work, towing, or mixed-use role.
The 2002 GMC Trucks Sierra 3500 SLE (DRW) Front uses 225/75R16, the dually-specific radial size. Tire choice should reflect the truck's front dually wheel arrangement and not the wider 245/75R16 size used on single-rear-wheel SLE models.
The 2002 GMC Trucks Sierra 3500 SLE (DRW) Rear uses 225/75R16 on the rear dual-wheel setup. Selecting tires for this position means staying with the correct dually size and checking the rear wheel package carefully before replacing anything.
The 2002 GMC Trucks Sierra 3500 SLT uses 245/75R16 in standard single-rear-wheel configuration. The main decision is then choosing the right tire within that size while confirming that the truck still has the proper 16-inch wheels and load-capable setup.
The 2002 GMC Trucks Sierra 3500 SLT (DRW) Front uses the narrower 225/75R16 dually tire size. This fitment should be matched to the front DRW wheel arrangement, with attention to wheel condition and the truck's actual current setup.
The 2002 GMC Trucks Sierra 3500 SLT (DRW) Rear also uses 225/75R16 for the rear dual-wheel application. Tire selection should stay specific to the dually rear setup, since the single-rear-wheel 245/75R16 size serves a different configuration.
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.

These FAQs focus on the tire-size split between single-rear-wheel and dually Sierra 3500 models, 16-inch rim fitment, product selection, and the maintenance checks that matter before putting a heavy-duty truck back on the road.
Tire Size & Fitment
What tire size fits a 2002 GMC Trucks Sierra 3500?
The 2002 GMC Trucks Sierra 3500 uses two primary tire sizes depending on configuration. Single-rear-wheel Base, SL, SLE, and SLT models use 245/75R16, while dual-rear-wheel front and rear positions use 225/75R16. Both fitments are radial tires designed for 16-inch rims.
The important step is identifying whether the truck is a standard rear-wheel Sierra 3500 or a dually. A trim badge alone is not always enough on an older work truck, especially if wheels or axles have been changed, so checking the actual wheel setup before choosing a tire is the safest approach.
What size rim does a 2002 GMC Trucks Sierra 3500 use?
The primary tire fitments for the 2002 GMC Trucks Sierra 3500 are built around a 16-inch rim diameter. Both 225/75R16 and 245/75R16 use that same 16-inch wheel diameter, even though the two tire sizes serve different truck configurations.
Rim diameter is only part of the fitment picture on a heavy-duty pickup. Wheel width still matters, and the available tires in these sizes have different rim-width ranges, so it is worth confirming the actual wheels on the truck before replacing tires, especially on dually trucks or trucks with aftermarket wheels.
Why does the 2002 GMC Trucks Sierra 3500 have more than one tire size?
The size split comes from configuration differences within the Sierra 3500 lineup. Single-rear-wheel versions use 245/75R16, while dual-rear-wheel front and rear applications use 225/75R16. The truck does not use two sizes interchangeably on the same setup; each size belongs to a specific wheel arrangement.
That means the first question is not which tire looks best, but which truck configuration is in front of you. Once the rear-wheel setup is confirmed, tire selection becomes much more straightforward, and the buyer can focus on load capacity, wheel-width compatibility, and the intended use of the truck.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 2002 GMC Trucks Sierra 3500?
Start by confirming that the truck is a single-rear-wheel 2002 GMC Trucks Sierra 3500, because 245/75R16 belongs to Base, SL, SLE, and SLT models in that configuration. The available tire in this size is the BFGoodrich All-Terrain T/A KO2, a radial light-truck tire with raised white letters and a 3,042-lb maximum load capacity at 80 psi.
Wheel compatibility still needs attention, since this tire calls for a 16-inch rim and a 6.5- to 8.0-inch rim-width range. It also helps to consider how the truck is used, whether that is hauling, towing, or mixed on-road use, so the chosen tire matches the truck's real workload.
What sidewall styles are available for 2002 GMC Trucks Sierra 3500 tires?
The available products for the 2002 GMC Trucks Sierra 3500 use an RWL sidewall, which means raised white letters. That sidewall treatment appears on both primary sizes covered here, so the truck's visible tire presentation stays consistent whether it uses 225/75R16 for dually applications or 245/75R16 for single-rear-wheel models.
Sidewall style matters mostly for appearance, but it is still secondary to choosing the correct size and wheel setup. A dually truck still needs the narrower 225/75R16 fitment, and a single-rear-wheel truck still needs 245/75R16, even though both are offered with the same raised white letter look.
What brands offer tires for the 2002 GMC Trucks Sierra 3500?
The available tires for the 2002 GMC Trucks Sierra 3500 are from BFGoodrich. Both primary sizes are represented through the All-Terrain T/A KO2 series, giving the truck a single brand and series path rather than a broad mix of different manufacturers or sidewall treatments.
That makes the main comparison less about brand choice and more about selecting the correct size for the truck's configuration. Once that is settled, the useful details to compare are load capacity, tire weight, rim-width range, and whether the truck is a single-rear-wheel model or a dually.
Restoration & Appearance
Which tire should I choose for a period-style 2002 GMC Trucks Sierra 3500?
A period-style choice for a 2002 GMC Trucks Sierra 3500 starts with using the correct original fitment type for the truck's configuration: 245/75R16 for single-rear-wheel models and 225/75R16 for dually front and rear positions. Both are radial truck sizes on 16-inch rims, which suits the Sierra 3500's early-2000s heavy-duty character.
Appearance comes after fitment on a truck like this. The available option uses a raised white letter sidewall, which gives a recognizable light-truck look, but exact originality should still be checked against vehicle-specific references if the goal is a highly accurate restoration or preservation project.
Does correct tire fitment matter for a 2002 GMC Trucks Sierra 3500 restoration?
Correct tire fitment matters because the 2002 GMC Trucks Sierra 3500 was offered in both single-rear-wheel and dual-rear-wheel form, and those configurations do not share the same tire size. Using 245/75R16 on a standard rear-wheel truck and 225/75R16 on dually front and rear positions keeps the truck aligned with its intended wheel setup.
Fitment also affects how the truck sits and functions, especially on a working heavy-duty chassis. Even on a restoration-oriented project, wheel diameter, rim width, and the actual axle setup should be verified carefully, since older trucks are often altered over time with replacement wheels or converted rear ends.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2002 GMC Trucks Sierra 3500?
Yes. Wheel changes, suspension alterations, axle swaps, lift kits, lowering, or a conversion between single-rear-wheel and dual-rear-wheel setups can all affect tire fitment on a 2002 GMC Trucks Sierra 3500. That matters because this truck normally uses either 245/75R16 or 225/75R16 depending on how the chassis is configured.
A truck that has seen work use may not still match its original setup, so checking the actual wheel diameter, wheel width, and rear-wheel arrangement is important before replacing tires. Clearance at the front suspension, rear fenders, and between dual rear tires should also be inspected on modified trucks.
What should I inspect before driving a 2002 GMC Trucks Sierra 3500 on new tires?
Before road use, inspect wheel condition, lug hardware, valve stems, and the overall tire installation on the 2002 GMC Trucks Sierra 3500. Tire pressure should match the tire's intended service, and the owner should look closely for rubbing, uneven spacing on dually rear tires, or signs that the truck's wheel setup does not match the selected size.
A heavy-duty truck also deserves a close look at suspension and steering condition before longer use. Worn components can affect how a new tire behaves, and any signs of air loss, vibration, or contact with suspension or body parts should be addressed immediately rather than assumed to correct themselves.
How should tires on a collector or low-use 2002 GMC Trucks Sierra 3500 be maintained?
Low-use tires on a 2002 GMC Trucks Sierra 3500 should still be inspected regularly for cracking, cuts, bulges, irregular wear, and air loss even if the truck is driven only occasionally. This matters on heavy-duty pickups because long idle periods can hide aging or pressure loss until the truck is suddenly asked to carry weight or travel farther.
Proper inflation, clean storage conditions, and occasional movement help reduce flat spotting and prolonged stress on one section of the tire. It also helps to keep the truck away from extended heat, direct sunlight, and ozone sources, then recheck pressures and visual condition before putting it back into service.
