The 1997 GMC Trucks K2500 Suburban sits in the era when heavy-duty sport utility vehicles were expected to tow, haul, and cover long miles without giving up full-size utility. Its three-quarter-ton chassis makes tire fitment more than a cosmetic decision, because the right size also supports the truck’s working character. For this model, the primary fitment is 245/75R16 in radial construction on a 16-inch rim. Available choices in this size lean toward an all-terrain, raised white letter presentation rather than a vintage-style sidewall treatment. The real decision is matching that correct size to your Suburban’s intended use, wheel setup, and load needs.
Which Tire Size Is Right for The 1997 GMC Trucks K2500 Suburban
The 1997 GMC Trucks K2500 Suburban uses one primary tire size: 245/75R16. It is a radial fitment for a 16-inch rim, and that same size is shared across Base, SLE, and SLT sub-models. With the size itself established, the decision shifts to choosing the right tire within that fitment and confirming that the wheel width, load capacity, and overall vehicle setup still suit the tire you plan to run.
245/75R16 is a metric radial size in which 245 refers to nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On a 1997 GMC Trucks K2500 Suburban, that radial format suits the truck’s late-1990s heavy-duty utility role and 16-inch wheel fitment. Available choices in this size include BFGoodrich’s All Terrain TA KO2 with a raised white letter sidewall. It is the right starting point when the goal is to keep the Suburban in its proper size while choosing a tread and sidewall style that matches how the vehicle is used.
Tire fitment is straightforward across the covered 1997 GMC Trucks K2500 Suburban sub-models. Base, SLE, and SLT all use the same 245/75R16 radial size, so the main task is confirming the actual wheels on the vehicle and then selecting the tire characteristics that best match your use.

1997 GMC Trucks K2500 Suburban Base
The 1997 GMC Trucks K2500 Suburban Base uses the same 245/75R16 radial fitment as the other covered sub-models. That keeps size selection simple and lets the focus move to wheel-width compatibility, load needs, and whether an all-terrain tire profile suits the way the truck is driven.
The 1997 GMC Trucks K2500 Suburban SLE also uses 245/75R16 radial tires on a 16-inch wheel fitment. Since the size remains consistent, the buying decision centers more on tire construction details, sidewall presentation, and making sure the truck has not been changed from its original wheel setup.
The 1997 GMC Trucks K2500 Suburban SLT shares the same 245/75R16 radial tire size as Base and SLE versions. That means tire selection is less about trim level and more about choosing a tire that meets the Suburban’s wheel dimensions, expected load, and real road or trail use.
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 1997 GMC Trucks K2500 Suburban?
The 1997 GMC Trucks K2500 Suburban uses 245/75R16 tires. That size is a radial fitment and applies across the covered Base, SLE, and SLT sub-models, so the primary size question is straightforward for this vehicle.
What still needs to be checked is the actual wheel and vehicle setup on the truck in front of you. A Suburban that has aftermarket wheels, suspension changes, or a mixed set of replacement parts may need closer inspection before tire selection, even when 245/75R16 is the correct original fitment size.
What size rim does a 1997 GMC Trucks K2500 Suburban use?
The 1997 GMC Trucks K2500 Suburban uses a 16-inch rim with its 245/75R16 tire size. Available tires in this fitment 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.
Diameter is only the first checkpoint. It is also important to confirm wheel width, especially on a truck that may have seen replacement wheels over the years. Staying within the tire’s supported rim-width range helps preserve the intended tire shape and gives a better baseline for clearance and load support.
Do all 1997 GMC Trucks K2500 Suburban sub-models use the same tire size?
Yes. Base, SLE, and SLT versions of the 1997 GMC Trucks K2500 Suburban all use the same 245/75R16 radial tire size. That shared fitment removes the usual need to sort between trim-specific tire sizes before looking at tire choices.
Even with consistent sub-model fitment, the truck’s present condition still matters. A Suburban used for towing, hauling, or fitted with non-original wheels should be checked for wheel width, tire load suitability, and clearance at full steering lock so the replacement tire matches the way the vehicle is actually set up.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 1997 GMC Trucks K2500 Suburban?
Start with the correct 245/75R16 size and radial construction, then compare the tire’s intended use, rim-width compatibility, and load capacity. For this Suburban, available product details include a 6.5- to 8.0-inch rim-width range and a maximum load capacity of 3,042 lbs @ 80 psi.
A three-quarter-ton Suburban places more importance on support and real-world use than a purely cosmetic tire choice. It helps to think about how the truck is driven, whether it sees towing or cargo duty, and whether the wheel setup is still stock before settling on a final tire within the correct size.
What sidewall styles are available for 1997 GMC Trucks K2500 Suburban tires?
Available 245/75R16 fitment for the 1997 GMC Trucks K2500 Suburban includes an RWL sidewall, commonly described as raised white letter. That gives the truck a more assertive late-1990s light-truck look than a plain blackwall presentation.
Sidewall style does not change the vehicle’s basic fitment, but it does affect the finished appearance. Raised white letters tend to suit owners who want a more traditional SUV or truck stance, while the more important checks remain the tire’s size, wheel compatibility, and whether the tread style matches the Suburban’s use.
What brands offer tires for the 1997 GMC Trucks K2500 Suburban?
BFGoodrich is represented in the 245/75R16 fitment for the 1997 GMC Trucks K2500 Suburban with the All Terrain TA KO2 series. That makes the available selection more about evaluating the tire’s specifications and intended use than comparing a long list of competing brands in this exact fitment set.
Brand alone should not decide the purchase on a heavy-duty Suburban. It is more useful to compare whether the tire matches the wheel width, carries the appropriate load for the truck’s duties, and delivers the tread and sidewall character that makes sense for road use, trail use, or mixed driving.
Restoration & Appearance
Which tire should I choose for a period-style 1997 GMC Trucks K2500 Suburban?
A period-style approach starts with the correct 245/75R16 radial size on a 16-inch wheel. On this 1997 GMC Trucks K2500 Suburban, that means keeping the proper overall fitment first, then choosing a tire whose tread and sidewall character suit the truck’s late-1990s heavy-duty SUV appearance.
A raised white letter all-terrain tire gives a distinctly era-appropriate light-truck presentation, but appearance should stay secondary to fitment. Owners aiming for a more exact restoration look should compare surviving original examples, brochures, or marque-specific references so the final choice matches the truck’s intended finished style.
How does tire construction affect the appearance of a restored 1997 GMC Trucks K2500 Suburban?
Construction is simple on this vehicle because the primary fitment is already radial. That means appearance differences are shaped less by bias-ply versus radial concerns and more by the tire’s tread pattern, sidewall styling, and how the finished tire fills the wheel opening in the correct 245/75R16 size.
For a restoration-oriented truck, keeping the proper size matters because an oversized or undersized replacement can change the visual balance quickly. Sidewall presentation also plays a major role, so details such as raised white letters versus a plainer look can shift the Suburban from work-truck plainness to a more period-style sport utility character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1997 GMC Trucks K2500 Suburban?
Yes. Even though 245/75R16 is the correct tire size for a 1997 GMC Trucks K2500 Suburban, wheel swaps, suspension lifts, lowering, worn springs, or body changes can alter how that size sits and clears. The tire size itself may remain correct while the truck’s current setup creates new fitment variables.
That is why it helps to inspect wheel width, steering clearance, and space at the fenders before replacing tires on a modified Suburban. A heavy-duty SUV can hide small fitment issues until it is loaded or turned sharply, so checking the actual vehicle prevents surprises after the new tires are mounted.
What should I inspect before driving a 1997 GMC Trucks K2500 Suburban on new tires?
Inspect the wheels for correct diameter and width, confirm the tires are inflated appropriately for their application, and look over suspension and steering components for looseness or wear. It also makes sense to check for any signs of rubbing at the inner fenders, frame, or steering stops once the new tires are installed.
A 1997 GMC Trucks K2500 Suburban is a substantial vehicle, so roadworthiness depends on more than fresh rubber alone. Wheel hardware, alignment condition, brake feel, and even old shock absorbers can influence how a new set of tires behaves, especially on a truck expected to carry passengers, cargo, or trailer weight.
How should 245/75R16 tires on a collector 1997 GMC Trucks K2500 Suburban be maintained?
Collector-use tires still need regular air-pressure checks, visual inspections, and protection from long periods of heat, sunlight, and moisture. On 245/75R16 tires, watch for sidewall cracking, bulges, cuts, uneven tread wear, and gradual air loss, especially if the Suburban spends long stretches parked between drives.
Maintenance also includes moving the truck often enough to avoid letting one area of the tire sit under load for too long. Before a longer trip, check tread condition, valve stems, and overall tire age, because a low-use heavy SUV can appear fine at a glance while still needing closer attention before highway use.
