The 1998 Chevrolet Trucks K1500 comes from the final years of Chevrolet’s GMT400 pickup era, a generation known for blending everyday usability with the rugged four-wheel-drive character that made these trucks longtime favorites on the road, at the jobsite, and on back-country routes. For this exact K1500, the tire decision centers on two primary radial sizes, 245/75R16 and 265/75R16, both built for 16-inch rims. That keeps the focus less on bias-ply-versus-radial questions and more on confirming the truck’s actual wheel and size setup. With BFGoodrich All-Terrain T/A KO2 options and raised white letter styling available, the right choice depends on stance, wheel width, and intended use.
Which Tire Size Is Right for The 1998 Chevrolet Trucks K1500
The 1998 Chevrolet Trucks K1500 uses two primary tire sizes, and both are radial tires for 16-inch rims. Since Cheyenne, Silverado, and WT models can use either size, the key step is confirming which wheel-and-tire setup is actually on the truck before choosing a replacement. Once size is confirmed, the decision becomes selecting the right width, rim-width match, and product specifications for how the truck is driven.
245/75R16 is a metric radial size in which 245 refers to section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 16 is the required rim diameter in inches. On the 1998 Chevrolet Trucks K1500, this size represents one of the standard 16-inch radial fitments and keeps the truck in a modern light-truck sizing format familiar to many owners. Available options include BFGoodrich’s All-Terrain T/A KO2 with raised white letter sidewalls. This size is worth considering when matching an existing 16-inch wheel setup and preserving the truck’s current tire width and overall stance.
265/75R16 follows the same metric radial format, with 265 indicating section width in millimeters, 75 showing the aspect ratio, R for radial construction, and 16 for rim diameter. For the 1998 Chevrolet Trucks K1500, it is the wider of the two primary 16-inch fitments and remains part of the truck’s radial-era tire selection. BFGoodrich All-Terrain T/A KO2 is available in this size as a raised white letter option. It is a practical size to evaluate when the truck already wears the wider factory-type fitment or when wheel width and clearance support that setup.
Tire fitment is straightforward across the covered 1998 Chevrolet Trucks K1500 sub-models because Cheyenne, Silverado, and WT can all use the same two primary sizes. The important step is verifying which 16-inch size is actually mounted on the truck before selecting a replacement.

1998 Chevrolet Trucks K1500 Cheyenne
The 1998 Chevrolet Trucks K1500 Cheyenne can use either of the two primary 16-inch radial sizes offered for this truck. That means tire selection starts with confirming the current wheel-and-tire setup, then choosing the size and product specifications that match the truck’s stance and intended use.
The 1998 Chevrolet Trucks K1500 Silverado shares the same basic tire-fitment situation, with both primary 16-inch radial sizes applying to this sub-model. The real decision is not trim-specific sizing so much as verifying the truck’s existing wheel setup and selecting the correct replacement width and rim-width range.
The 1998 Chevrolet Trucks K1500 WT also uses the same two 16-inch radial tire sizes found elsewhere in the K1500 lineup. That makes wheel confirmation especially important, since the correct replacement depends on the actual tire size mounted on the truck rather than the sub-model name alone.
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.
Best 1998 Chevrolet Trucks K1500 Tires for Sale
Available 1998 Chevrolet Trucks K1500 tire choices center on BFGoodrich All-Terrain T/A KO2 fitments in both 245/75R16 and 265/75R16. The product grid lets you compare raised white letter styling, radial construction, rim-width compatibility, load capacity, and other size-specific specifications.
Common 1998 Chevrolet Trucks K1500 tire questions usually come down to confirming whether the truck uses 245/75R16 or 265/75R16, checking 16-inch wheel fitment, and comparing the available all-terrain replacement options for appearance, use, and maintenance.
Tire Size & Fitment
What tire size fits a 1998 Chevrolet Trucks K1500?
A 1998 Chevrolet Trucks K1500 uses either 245/75R16 or 265/75R16, and both are radial tire sizes for 16-inch rims. Cheyenne, Silverado, and WT versions can all use those same primary sizes, so the truck does not break into separate trim-specific tire sizing the way some other vehicles do.
That means the first step is confirming which of those two sizes is actually on the truck now. Checking the sidewall size, wheel width, and overall clearance matters before replacing a tire, especially on older trucks that may have had wheel changes, suspension work, or prior size substitutions during their service life.
What size rim does a 1998 Chevrolet Trucks K1500 use?
The primary tire sizes for a 1998 Chevrolet Trucks K1500 both use a 16-inch rim diameter. That applies whether the truck is fitted with 245/75R16 or 265/75R16, so the key shared fitment point is the 16-inch wheel rather than a change in diameter between the two sizes.
Rim diameter is only part of the fitment picture, though. Wheel width also matters, because the available 245/75R16 and 265/75R16 products call for different rim-width ranges. Before replacing tires, confirm the wheel’s actual diameter and width so the selected tire matches both the truck and the wheel already in service.
Do all 1998 Chevrolet Trucks K1500 sub-models use the same tire size?
Cheyenne, Silverado, and WT versions of the 1998 Chevrolet Trucks K1500 share the same two primary tire sizes: 245/75R16 and 265/75R16. In other words, the covered sub-models use the same fitment range rather than each trim having its own separate tire size assignment.
That shared fitment range does not mean every individual truck should automatically switch between the two sizes without checking details first. Owners should confirm the wheel width, current installed size, and any clearance-sensitive changes such as aftermarket wheels or altered ride height before choosing between the narrower and wider K1500 tire options.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 or 265/75R16 tire for a 1998 Chevrolet Trucks K1500?
Start by confirming which of the two primary sizes your 1998 Chevrolet Trucks K1500 actually uses, since both 245/75R16 and 265/75R16 are correct fitments for this model family. From there, compare construction, intended use, rim-width compatibility, load capacity, and the truck’s current wheel setup rather than choosing only by appearance.
A K1500 used for regular road driving may call for different priorities than one that sees rougher surfaces or a more aggressive stance. It also helps to compare the product’s rim-width range and load figure with the existing wheel and how the truck is used, especially if it still handles work, towing, or mixed on-road and off-road driving.
What sidewall styles are available for 1998 Chevrolet Trucks K1500 tires?
The available tire options for this 1998 Chevrolet Trucks K1500 use RWL sidewalls, meaning raised white letters. That gives the truck a more traditional light-truck appearance than a plain blackwall and suits owners who want an all-terrain tire with a recognizable period-appropriate late-1990s visual style.
Sidewall appearance should still come after confirming the correct tire size and wheel fitment. Once those basics are right, raised white letters become a styling decision that can change the truck’s look significantly, especially on a GMT400 pickup where the tire sidewall is a visible part of the overall stance and presentation.
What tire series are available for the 1998 Chevrolet Trucks K1500?
The available tire series for the 1998 Chevrolet Trucks K1500 is the BFGoodrich All-Terrain T/A KO2. It is offered in both primary sizes, 245/75R16 and 265/75R16, and gives buyers a consistent all-terrain product family to compare across the truck’s two supported 16-inch radial fitments.
Because the series remains the same across both sizes, the main comparison shifts to width, wheel compatibility, load rating, and how the truck is used. That simplifies brand and series selection, but it makes size confirmation even more important, since the practical difference comes from the tire dimensions and wheel match rather than a different tread family.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Chevrolet Trucks K1500?
For a period-style 1998 Chevrolet Trucks K1500, the starting point is keeping the truck in one of its correct primary sizes, either 245/75R16 or 265/75R16, on the proper 16-inch wheel. Since this truck is already in the radial era, the period-style question is more about size, stance, and sidewall presentation than about returning to older bias-ply construction.
A raised white letter all-terrain tire can support that late-1990s truck look well, especially on a four-wheel-drive pickup. Owners focused on a highly exact restoration should still compare the truck’s current setup with original vehicle paperwork, sales literature, or marque-specific references so appearance choices stay in line with the build being recreated.
Does correct tire fitment matter for a 1998 Chevrolet Trucks K1500 restoration?
Correct tire fitment matters on a 1998 Chevrolet Trucks K1500 restoration because tire size affects the truck’s stance, wheelwell appearance, and overall visual balance. Staying with the proper 16-inch rim diameter and the appropriate 245/75R16 or 265/75R16 sizing keeps the restored truck closer to the way this generation of K1500 was meant to sit and present itself.
Fitment also matters mechanically, not just visually. A restoration-minded owner should confirm the wheel width, current suspension height, and any non-original wheel changes before settling on a replacement tire, since a truck can look correct at a glance yet still have a setup that changes how a replacement tire sits or clears.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Chevrolet Trucks K1500?
Yes, modifications can affect tire fitment on a 1998 Chevrolet Trucks K1500 even when the truck stays with one of its correct primary sizes. Aftermarket wheels, different wheel widths, suspension lifts or drops, and body changes can all alter how a 245/75R16 or 265/75R16 tire sits in the wheel opening and clears through steering travel.
That is why replacement should begin with the actual truck in front of you, not assumptions about what it left the factory with decades ago. A quick check of wheel width, installed tire size, steering clearance, and suspension condition helps avoid choosing a tire that matches the model family on paper but conflicts with the truck’s present setup.
What should I inspect before driving a 1998 Chevrolet Trucks K1500 on new tires?
Before driving a 1998 Chevrolet Trucks K1500 on new tires, inspect the wheels for correct diameter and width, verify lug hardware condition, and make sure the tires are inflated appropriately for the application. It also helps to check steering components, shocks, and alignment condition so the new tires are not immediately compromised by worn front-end or suspension parts.
A short clearance check is just as important, especially on a four-wheel-drive truck. Turn the steering from lock to lock, look for contact near the fenders and suspension, and watch for uneven ride height or sagging springs that could reduce space. Catching those issues early helps the new tires wear more evenly and behave more predictably on the road.
How should 245/75R16 or 265/75R16 tires on a collector 1998 Chevrolet Trucks K1500 be maintained?
Tires on a collector-grade 1998 Chevrolet Trucks K1500 should be checked regularly for air loss, tread wear, sidewall cracking, bulges, cuts, and signs of age-related hardening. That matters even on trucks driven only occasionally, because low annual mileage does not stop rubber from aging or prevent problems caused by long periods of storage.
Consistent pressure checks and proper storage conditions go a long way toward preserving a lightly used pickup’s tires. Keeping the truck away from prolonged sun, excess heat, standing moisture, and ozone sources helps, and periodic inspections remain important after storage because an older truck can look ready for the road while the tires need closer attention.
