The 1998 GMC Trucks C2500 Suburban sits in the last stretch of the traditional full-size SUV era, when heavy-duty Suburban models were expected to handle family hauling, towing, and long highway miles with equal confidence. Its three-quarter-ton character makes tire choice more than a cosmetic decision, because the vehicle depends on a substantial light-truck radial fitment. The 1998 GMC Trucks C2500 Suburban uses a 245/75R16 radial tire on a 16-inch rim, and that keeps the selection process focused on choosing the right product within one established size. For most owners, the key questions are load-minded road use, sidewall presentation, and wheel compatibility rather than alternate sizing.
Which Tire Size Is Right for The 1998 GMC Trucks C2500 Suburban
The 1998 GMC Trucks C2500 Suburban uses one primary tire size: 245/75R16. This is a radial tire fitment for a 16-inch rim, and it stays consistent across Base, SLE, and SLT models. That means the main decision is not sorting through multiple factory sizes, but choosing the right tire within 245/75R16 based on load capability, intended use, sidewall style, and wheel compatibility.
In 245/75R16, the 245 identifies the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 16 is the wheel diameter in inches. This modern metric radial format suits the heavy-duty character of the 1998 GMC Trucks C2500 Suburban and keeps the vehicle on its intended 16-inch rim size. Available choices in this size include BFGoodrich's All Terrain TA KO2 with raised white letter sidewalls. It is the size to use when maintaining the Suburban's established fitment while selecting a tire that matches road use, wheel width, and overall truck presentation.
Tire fitment is straightforward across the covered 1998 GMC Trucks C2500 Suburban sub-models. Base, SLE, and SLT all use the same primary tire size, so the focus stays on choosing the right 245/75R16 tire rather than sorting through different factory fitments.

1998 GMC Trucks C2500 Suburban Base
The 1998 GMC Trucks C2500 Suburban Base uses the same 245/75R16 radial tire fitment as the other covered sub-models. That keeps selection centered on tire type, sidewall appearance, and wheel-width compatibility instead of chasing a trim-specific alternate size.
The 1998 GMC Trucks C2500 Suburban SLE also uses 245/75R16 radial tires on a 16-inch rim. For SLE owners, the practical choice is comparing available products in that size for load-minded use, appearance, and compatibility with the actual wheels on the vehicle.
The 1998 GMC Trucks C2500 Suburban SLT shares the same 245/75R16 radial tire fitment. Tire shopping for the SLT is therefore about selecting the right product within the correct size and confirming the wheel setup before mounting a new set.
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 1998 GMC Trucks C2500 Suburban?
The 1998 GMC Trucks C2500 Suburban uses a 245/75R16 radial tire. That size applies across the covered Base, SLE, and SLT sub-models, so there is one primary fitment to work from when replacing tires on this vehicle.
Having one established size simplifies the search, but the job is not finished once the size matches. Confirm that the Suburban still has 16-inch wheels, then compare the tire's intended use, load specification, and wheel-width compatibility so the replacement suits the actual vehicle setup.
What size rim does a 1998 GMC Trucks C2500 Suburban use?
The primary tire fitment for the 1998 GMC Trucks C2500 Suburban uses a 16-inch rim. That matches the 245/75R16 tire size, where the final number in the size code identifies the wheel diameter in inches.
Wheel diameter is the first check before buying tires, especially on older trucks and SUVs that may have seen wheel changes over time. After confirming the 16-inch diameter, it is also worth checking actual wheel width so the chosen tire stays within the manufacturer's approved rim-width range.
Do all 1998 GMC Trucks C2500 Suburban sub-models use the same tire size?
Yes. The covered 1998 GMC Trucks C2500 Suburban Base, SLE, and SLT models all use the same 245/75R16 radial tire size. There is no trim split here that requires different primary sizing among those sub-models.
That consistency makes shopping easier, but it still helps to verify what is physically on the vehicle today. A Suburban with aftermarket wheels, suspension changes, or a previous owner's tire swap may need a closer look at wheel diameter, width, and clearance before installing new tires.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 1998 GMC Trucks C2500 Suburban?
Start with the established 245/75R16 size and make sure the tire is appropriate for a heavy-duty Suburban's weight and intended use. Construction is already radial here, so the next decisions usually involve load-minded specifications, on-road versus mixed-use driving, and wheel compatibility.
A useful comparison includes sidewall style, approved rim-width range, and how the tire will be used day to day. A Suburban that sees towing, highway travel, or occasional rough-surface driving may call for a different product emphasis than one used mainly for casual cruising and storage.
What sidewall styles are available for 1998 GMC Trucks C2500 Suburban tires?
The available 245/75R16 product offering for the 1998 GMC Trucks C2500 Suburban includes an RWL sidewall, which is a raised white letter presentation. That gives the tire a more traditional light-truck look than a plain black sidewall treatment.
Sidewall style does not change the basic fitment, but it does influence the vehicle's overall appearance. Raised white letters can suit a truck-oriented late-1990s look, while some owners may want to think about how visible lettering fits the Suburban's original wheels, trim level, and intended presentation.
What brands offer tires for the 1998 GMC Trucks C2500 Suburban?
The available tire choice in the primary 245/75R16 size includes BFGoodrich. The product offering here is the All Terrain TA KO2, a radial light-truck tire built around the Suburban's established 16-inch fitment.
Brand matters less than choosing the right specification for the vehicle's use and wheel setup. It helps to compare sidewall treatment, approved rim-width range, and load-related specs so the tire matches how the C2500 Suburban is actually driven rather than selecting on name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1998 GMC Trucks C2500 Suburban?
A period-style starting point for a 1998 GMC Trucks C2500 Suburban begins with the correct 245/75R16 radial size on a 16-inch rim. Keeping the established size preserves the truck's overall stance and avoids turning a restoration-minded project into an unnecessary fitment experiment.
Appearance then comes down to product character and sidewall presentation. An RWL tire gives the Suburban a recognizable late-1990s truck look, but exact originality can vary by vehicle history and owner preference, so anyone pursuing a highly exact restoration should compare against marque references and period photos.
How does tire construction affect the appearance of a restored 1998 GMC Trucks C2500 Suburban?
The 1998 GMC Trucks C2500 Suburban uses a radial tire fitment, so staying with a radial construction keeps the vehicle aligned with its established late-model truck presentation. On a vehicle from this era, construction choice is less about vintage bias-ply character and more about maintaining the proper modern truck profile.
Visual differences still come from details such as sidewall treatment, tread character, and how the tire fills the wheel opening in the correct size. For a restoration-oriented truck, the cleaner approach is usually to preserve the 245/75R16 fitment and choose a sidewall style that suits the Suburban's intended look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 GMC Trucks C2500 Suburban?
Yes. Even though the primary tire size is 245/75R16, modifications can change whether that size still works the same way on a particular 1998 GMC Trucks C2500 Suburban. Wheel changes, altered offsets, suspension lifts or drops, and body alterations can all affect clearance and overall fitment.
A Suburban that still uses stock-type wheels is simpler to evaluate than one with aftermarket parts. Check actual wheel diameter and width, then look at steering travel, fender clearance, and suspension space so the replacement tire matches the vehicle as it sits today.
What should I inspect before driving a 1998 GMC Trucks C2500 Suburban on new tires?
Before road use, inspect wheel condition, lug hardware, valve stems, and the tire's inflation level. It also helps to confirm that each new 245/75R16 tire seats properly on the wheel and that there is no rubbing at the front suspension, steering components, or inner fender areas.
A heavy-duty Suburban benefits from a broader once-over before regular driving resumes. Look at alignment-related wear, brake condition, and suspension play, then recheck tire pressure after the first miles of use so the new set starts out with stable wear and consistent road manners.
How should 245/75R16 tires on a collector 1998 GMC Trucks C2500 Suburban be maintained?
Collector-use tires on a 1998 GMC Trucks C2500 Suburban should be kept properly inflated, inspected regularly, and protected from long idle periods that can hide age-related deterioration. Even a tire with good tread can develop cracking, hardening, bulges, or air-loss issues if the vehicle spends long stretches parked.
Routine care includes checking pressures before driving, examining tread and sidewalls, and storing the vehicle away from prolonged sunlight, heat, and ozone sources when possible. Rolling the Suburban periodically and keeping the suspension and alignment in sound condition also helps the tires wear more evenly over time.
