The 2002 GMC Trucks Sierra 2500 sits in the heavy-duty pickup era when three-quarter-ton trucks were expected to handle work duty during the week and long highway miles on the weekend. Buyers still value these trucks for their straightforward durability, towing capability, and broad usefulness. For this exact Sierra 2500 fitment, the primary tire size is 245/75R16 in radial construction on a 16-inch rim. That keeps the tire decision focused less on finding the right size and more on choosing the right type of tire within that size, including an all-terrain option with raised white letters. Before changing anything, it makes sense to confirm the truck's actual wheels and intended use.
Which Tire Size Is Right for The 2002 GMC Trucks Sierra 2500
The 2002 GMC Trucks Sierra 2500 uses one primary tire size: 245/75R16. It is a radial fitment on a 16-inch rim, and that same size carries across the covered Base, SL, SLE, and SLT sub-models. Since the size itself is straightforward, the real choice becomes selecting the right tire type, sidewall presentation, and use-focused tread while confirming that the truck still has the correct wheel setup.
A 245/75R16 size is a metric radial designation: 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, this is the core fitment and it matches the truck's heavy-duty pickup role. Available choices in this size include BFGoodrich's All Terrain TA KO2 with raised white letter sidewall styling. It is the size to evaluate when the goal is maintaining the intended 16-inch fitment while choosing a tire suited to the truck's work, road, or mixed-use demands.
Tire fitment is straightforward across the covered 2002 GMC Trucks Sierra 2500 sub-models. Base, SL, SLE, and SLT versions all share the same 245/75R16 radial size, so sub-model selection matters less than confirming that the truck still wears the correct 16-inch wheels.

2002 GMC Trucks Sierra 2500 Base
The 2002 GMC Trucks Sierra 2500 Base uses the same 245/75R16 radial fitment as the other covered sub-models. That keeps tire selection centered on tread type, sidewall appearance, and wheel compatibility rather than on sub-model-specific size differences.
The 2002 GMC Trucks Sierra 2500 SL also uses 245/75R16 radial tires on a 16-inch wheel. For this sub-model, the main decision is choosing a tire that matches how the truck is actually used, especially if it sees both paved-road and off-pavement driving.
The 2002 GMC Trucks Sierra 2500 SLE shares the same 245/75R16 radial size used throughout this fitment group. Tire choice comes down to selecting the right product characteristics within that size and confirming the wheel width remains appropriate for the tire.
The 2002 GMC Trucks Sierra 2500 SLT uses the same 245/75R16 radial tire size as the other listed trims. That makes the fitment process simpler, with attention shifting toward tire style, load capability, and whether the truck still has its intended wheel setup.
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)

Tire Size & Fitment
What tire size fits a 2002 GMC Trucks Sierra 2500?
The 2002 GMC Trucks Sierra 2500 uses 245/75R16 tires in radial construction. That is the primary fitment across the covered Base, SL, SLE, and SLT sub-models, so the tire-size question is unusually straightforward for this truck.
Once the size is confirmed, the next step is making sure the truck still has 16-inch wheels that match the intended setup. A Sierra 2500 that has been changed to aftermarket wheels, different offsets, or another diameter should be checked carefully before choosing a new 245/75R16 tire.
What size rim does a 2002 GMC Trucks Sierra 2500 use?
This 2002 GMC Trucks Sierra 2500 fitment uses a 16-inch rim with the 245/75R16 tire size. Available tires in this size include options built for a rim-width range of 6.5 to 8.0 inches, which helps frame the wheel-compatibility side of the decision.
Rim diameter is the first item to verify, but wheel width matters too. A truck with replacement wheels may still be 16-inch diameter while using a width or offset that changes sidewall shape, clearance, or overall fitment behavior, so checking the actual wheel before purchase is worthwhile.
Do all 2002 GMC Trucks Sierra 2500 sub-models use the same tire size?
Yes. The covered 2002 GMC Trucks Sierra 2500 Base, SL, SLE, and SLT sub-models all use the same 245/75R16 radial tire size. There is no split here by trim level, which makes sub-model fitment much easier to sort out than on many other truck applications.
That shared fitment does not remove the need to inspect the truck itself. Over time, many heavy-duty pickups receive different wheels, suspension changes, or tire-size upgrades, so the practical check is whether the truck still matches the original 16-inch fitment before selecting a replacement tire.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 2002 GMC Trucks Sierra 2500?
Start with the correct 245/75R16 size, radial construction, and 16-inch rim requirement. From there, compare the tire's intended use, sidewall style, rim-width compatibility, and load-related specifications so the replacement suits how the Sierra 2500 is actually driven or worked.
A three-quarter-ton pickup often sees more demanding service than a light-duty truck, so appearance should not be the only deciding factor. It helps to match the tread type to the truck's job, confirm the wheel falls within the approved width range, and avoid assuming every 16-inch wheel setup behaves the same.
What sidewall styles are available for 2002 GMC Trucks Sierra 2500 tires?
The available 245/75R16 option for this 2002 GMC Trucks Sierra 2500 uses an RWL sidewall, meaning raised white letters. That gives the truck a more assertive period-appropriate light-truck look than a plain blackwall sidewall would provide.
Sidewall style is mostly an appearance choice, but it can matter if the truck is being kept close to a certain visual theme. A raised white letter presentation tends to suit many early-2000s truck builds, while buyers focused strictly on utility may place more weight on tread and load-related details.
What brands offer tires for the 2002 GMC Trucks Sierra 2500?
The current fitment offering in 245/75R16 for the 2002 GMC Trucks Sierra 2500 includes BFGoodrich. In this case, the brand appears in an all-terrain truck application rather than through a wider mix of touring, highway, and vintage-style product lines.
With only one visible brand choice in this fitment group, the decision shifts toward whether the tire's overall character suits the truck's needs. Buyers should focus on construction, wheel-width compatibility, sidewall presentation, and how much on-road versus off-road use the Sierra 2500 actually sees.
Restoration & Appearance
Which tire should I choose for a period-style 2002 GMC Trucks Sierra 2500?
A period-style starting point for a 2002 GMC Trucks Sierra 2500 is staying with the 245/75R16 radial size on a 16-inch wheel. That preserves the truck's basic fitment profile while letting the buyer choose a tire that still looks at home on an early-2000s heavy-duty pickup.
Appearance then comes down to the character of the tire itself. An all-terrain design with raised white letters gives a more era-appropriate truck presentation than a generic modern look, but buyers focused on strict originality should still compare details against photos, sales literature, or marque-specific references.
How does tire construction affect the appearance of a restored 2002 GMC Trucks Sierra 2500?
For this 2002 GMC Trucks Sierra 2500 fitment, radial construction is already the primary format, so the appearance question is less about bias-ply versus radial and more about tread style, sidewall treatment, and overall stance. The tire's visual character shapes the truck's finished look more than its construction category alone.
A truck restored with a road-focused tire can look very different from one wearing an all-terrain pattern and raised white letters, even in the same 245/75R16 size. Keeping the size correct helps preserve proportion, while the sidewall and tread style fine-tune whether the result feels stock-minded, work-truck, or more aggressive.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2002 GMC Trucks Sierra 2500?
Yes. Even though the core fitment is 245/75R16 on a 16-inch rim, modifications can change how that size works on a 2002 GMC Trucks Sierra 2500. Different wheel widths, offsets, suspension changes, or body alterations may affect clearance and overall tire position.
A truck that still carries its intended wheel setup is easier to match correctly. Once aftermarket wheels or ride-height changes enter the picture, it is smart to inspect inner-fender space, steering travel, and wheel dimensions rather than assuming the standard size will behave exactly the same as before.
What should I inspect before driving a 2002 GMC Trucks Sierra 2500 on new tires?
Inspect the wheels for the correct 16-inch diameter and appropriate width, then check lug hardware, valve stems, and overall wheel condition. On the tires themselves, confirm proper inflation, look for shipping or mounting damage, and make sure the tread and sidewalls are cleanly seated after installation.
A heavy-duty pickup also deserves a quick look at suspension, steering, and brake condition before regular road use. Uneven wear, looseness, or alignment issues can shorten tire life quickly, so a brief inspection after the first miles can help catch rubbing, pressure loss, or handling changes early.
How should 245/75R16 tires on a collector 2002 GMC Trucks Sierra 2500 be maintained?
Maintain 245/75R16 tires on a collector-use 2002 GMC Trucks Sierra 2500 by keeping inflation at the appropriate level for the tire and use, inspecting for cracking, cuts, bulges, and irregular wear, and checking for air loss during periods of storage. Regular movement helps prevent long-term flat spotting.
Storage conditions matter on low-use trucks. Keeping the Sierra 2500 away from prolonged sun, moisture, and ozone sources helps preserve the sidewalls, while occasional inspections of tread, wheel condition, and overall ride feel make it easier to catch age-related problems before a longer drive or towing trip.
