The 1998 Chevrolet Trucks K1500 Suburban came from the final years of the long-running GMT400 era, when full-size SUVs were expected to handle family duty, towing, winter weather, and long highway miles with equal confidence. That broad-use character makes tire choice especially important on a vehicle like this. The 1998 Chevrolet Trucks K1500 Suburban uses a single primary tire size, 245/75R16, in radial construction on a 16-inch rim. Available choices in that size lean toward a truck-ready, all-terrain presentation, including raised white letter styling. The right selection comes down to preserving the Suburban's intended stance, matching the wheel correctly, and choosing a tire suited to how the truck is actually used today.
Which Tire Size Is Right for The 1998 Chevrolet Trucks K1500 Suburban
The 1998 Chevrolet Trucks K1500 Suburban uses one primary tire size: 245/75R16 in radial construction on a 16-inch rim. That same size carries across the covered sub-models, so the main decision is not which size fits, but which tire style and specification best matches the truck's wheel width, intended use, and overall look.
Fit(s): (Diesel), Base, LS, LS (Diesel), LT, and LT (Diesel)
Construction: Radial|Rim: 16 in
A 245/75R16 tire uses a modern metric sizing format: 245 is the nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 16 is the rim diameter in inches. On the 1998 Chevrolet Trucks K1500 Suburban, this is the primary fitment and suits the vehicle's full-size truck-based character. Available choices in this size include BFGoodrich's All-Terrain T/A KO2 with raised white letter sidewalls. It is the right size to evaluate when the goal is keeping the proper overall fitment while choosing a tire that matches the Suburban's road use and wheel setup.
1998 Chevrolet Trucks K1500 Suburban Sub-Model Tires
Tire fitment is straightforward across the covered 1998 Chevrolet Trucks K1500 Suburban sub-models because they share the same primary tire size. Checking the exact sub-model still matters so the tire can be matched to the truck's actual wheel, condition, and intended use before installation.

Tire Size & Fitment
What tire size fits a 1998 Chevrolet Trucks K1500 Suburban?
The 1998 Chevrolet Trucks K1500 Suburban uses 245/75R16 tires in radial construction. That size applies across the covered sub-models, including Base, LS, LT, and the listed diesel versions, making fitment more straightforward than on vehicles with multiple factory size combinations.
The next step is confirming that the truck still has the correct 16-inch wheel setup and an appropriate wheel width for the tire being considered. A Suburban that has seen aftermarket wheel changes, suspension work, or long-term service use should be checked at the vehicle before replacement tires are chosen.
What size rim does a 1998 Chevrolet Trucks K1500 Suburban use?
The primary tire fitment for the 1998 Chevrolet Trucks K1500 Suburban uses a 16-inch rim. The available 245/75R16 product also carries a rim-width range of 6.5 to 8.0 inches, which helps define the wheel dimensions that should be matched during tire selection.
Rim diameter and rim width both matter, especially on older full-size trucks that may have had wheels replaced over the years. Measuring the actual wheel and checking its width before mounting new tires helps prevent mismatch issues and keeps the 245/75R16 size aligned with the tire manufacturer's intended fitment range.
Do all 1998 Chevrolet Trucks K1500 Suburban sub-models use the same tire size?
Yes. The covered 1998 Chevrolet Trucks K1500 Suburban sub-models all use the same primary tire size, 245/75R16 in radial construction. That includes Base, LS, LT, and the listed diesel variants, so there is no split primary size within these sub-models.
Even with shared fitment, it is still smart to inspect the vehicle itself before buying tires. Wheel changes, replacement axles, lift components, or different service-life modifications can affect what is currently on the truck, so verifying the existing wheel and tire setup remains a worthwhile final check.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 1998 Chevrolet Trucks K1500 Suburban?
Start with the basics: correct size, radial construction, and 16-inch wheel compatibility. On this Suburban, 245/75R16 is the key fitment, so the real comparison is between tire characteristics such as sidewall style, wheel-width range, maximum load specification, and the type of driving the truck sees.
A truck used for highway cruising may call for different priorities than one used on mixed pavement and gravel. It also helps to compare the wheel's actual width against the tire's approved range and to think about whether a more traditional black sidewall or a raised white letter look better suits the Suburban's appearance.
What sidewall styles are available for 1998 Chevrolet Trucks K1500 Suburban tires?
The available 245/75R16 fitment shown for the 1998 Chevrolet Trucks K1500 Suburban includes an RWL sidewall, meaning raised white letter styling. That gives the truck a more traditional light-truck appearance than a plain black sidewall and can matter just as much as the tread style for some owners.
Sidewall appearance does not change the tire size, but it does affect how the Suburban presents visually, especially on a late-1990s truck that still carries a period truck-SUV look. Choosing a sidewall treatment should come after size and wheel compatibility are confirmed, not before.
What brands offer tires for the 1998 Chevrolet Trucks K1500 Suburban?
The available product shown in 245/75R16 for the 1998 Chevrolet Trucks K1500 Suburban is from BFGoodrich. It is part of the All-Terrain T/A KO2 line, giving this fitment a recognizable light-truck tire option with radial construction and raised white letter sidewalls.
Brand is only one part of the decision. It still makes sense to compare the tire's wheel-width range, load specification, appearance, and the way the Suburban is driven today. A mostly street-driven SUV may be judged differently from one that sees rough roads, towing duty, or seasonal weather use.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Chevrolet Trucks K1500 Suburban?
A period-style starting point for a 1998 Chevrolet Trucks K1500 Suburban is the original-size format itself: 245/75R16 radial on a 16-inch rim. Keeping the correct size preserves the truck's overall stance more faithfully than jumping to a dramatically different size simply because it is easy to source.
Appearance then comes down to the tire's visual character within that size. A raised white letter sidewall can suit the late-1990s truck-SUV look especially well, while wheel width and actual ride use still need to be considered so the finished result looks right and functions properly on the vehicle.
Does correct tire fitment matter for a 1998 Chevrolet Trucks K1500 Suburban restoration?
Yes, correct tire fitment matters because tire size shapes both the visual stance and the practical usability of a restored 1998 Chevrolet Trucks K1500 Suburban. Staying with the proper 245/75R16 format keeps the truck anchored to the kind of full-size SUV proportions it was built around.
Restoration-oriented buyers should also pay attention to wheel dimensions and sidewall presentation, not just tread. A truck can look noticeably different when the wrong diameter, width, or sidewall style is used, so confirming the actual wheel setup is just as important as selecting the right nominal tire size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Chevrolet Trucks K1500 Suburban?
Yes. A 1998 Chevrolet Trucks K1500 Suburban may use the correct 245/75R16 tire size on paper, but wheel swaps, altered offset, lift kits, lowering changes, or worn suspension parts can all change how that tire fits on the truck in practice.
Clearance should be checked at full steering lock and through suspension travel, especially if the Suburban has aftermarket wheels or non-stock ride height. Verifying the current wheel diameter and width before buying tires helps avoid choosing a size that is correct for the model but mismatched to the truck's actual setup.
What should I inspect before driving a 1998 Chevrolet Trucks K1500 Suburban on new tires?
Before regular road use, inspect tire pressure, lug-nut torque, tread seating, and visible clearance around the fenders, steering components, and suspension. It is also wise to confirm that the 245/75R16 tires are mounted on the proper 16-inch wheels and that the wheel width suits the tire.
A full-size Suburban places real demands on its tires, so the rest of the vehicle should not be ignored. Checking alignment condition, shock and spring wear, brake function, and any signs of rubbing or air loss helps make sure the new tires are working with a sound chassis rather than masking another problem.
How should 245/75R16 tires on a collector 1998 Chevrolet Trucks K1500 Suburban be maintained?
245/75R16 tires on a collector-use 1998 Chevrolet Trucks K1500 Suburban should be kept at appropriate pressure, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long periods of heat, sunlight, moisture, and ozone exposure during storage.
Low-mileage trucks often age their tires before they wear them out, so visual condition matters as much as tread depth. Periodic rotation, checking for slow air loss, and giving the Suburban occasional exercise can help, but any sign of age-related deterioration should be taken seriously before highway driving.
