The 1991 Chevrolet Trucks K2500 belongs to an era when Chevrolet heavy-duty pickups were expected to balance real work capability with everyday road use. These trucks remain popular because they sit squarely between restoration interest and practical service, so tire choice still matters for both stance and function. The 1991 Chevrolet Trucks K2500 uses radial 16-inch fitments, with 225/75R16 and 245/75R16 both appearing across the model range. That keeps the decision centered on confirming the exact sub-model, then comparing the available all-terrain tire setup and sidewall presentation. For a truck that may still haul, tow, cruise, or show, wheel size and overall tire proportions should be checked before changing sizes.
Which Tire Size Is Right for The 1991 Chevrolet Trucks K2500
The 1991 Chevrolet Trucks K2500 uses two primary tire sizes, and both are radial fitments built for 16-inch rims. Size choice depends first on the exact sub-model, since some versions use either 225/75R16 or 245/75R16 while extended cab models are tied to 245/75R16. Once that is confirmed, the next step is comparing tire width, rim-width compatibility, load capacity, and the type of all-terrain presentation you want from the truck.
225/75R16 is a metric radial size in which 225 refers to section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 16 is the rim diameter in inches. On the 1991 Chevrolet Trucks K2500, this size is one of the standard 16-inch fitments and keeps the truck in a modern radial sizing format. Available choices in this size include BFGoodrich's All Terrain TA KO2 with raised white letter sidewalls. It is a useful size to evaluate when maintaining the truck's intended fitment range without stepping up to the wider 245-series option.
Fit(s): Cheyenne, Cheyenne Ext. Cab, Silverado, and Silverado Ext. Cab
Construction: Radial|Rim: 16 in
245/75R16 follows the same metric radial format, with a 245-millimeter section width, a 75-series profile, radial construction, and a 16-inch rim diameter. For the 1991 Chevrolet Trucks K2500, this size appears across multiple sub-models and is the sole fitment for the extended cab versions listed here. BFGoodrich offers this size in the All Terrain TA KO2 with raised white letter sidewalls, giving it a traditional truck look with an off-road-oriented tread character. It deserves a closer look when the truck calls for the broader footprint and the wheel setup supports the size correctly.
Sub-model fitment matters on the 1991 Chevrolet Trucks K2500 because not every version uses the same size range. Cheyenne and Silverado can use either listed size, while the extended cab variants are tied to 245/75R16, so identifying the exact truck comes first.

1991 Chevrolet Trucks K2500 Cheyenne
The 1991 Chevrolet Trucks K2500 Cheyenne can use either of the primary radial 16-inch sizes offered for this model line. That means tire selection starts with confirming which wheel and tire setup is already on the truck before comparing width, load capacity, and all-terrain product details.
The 1991 Chevrolet Trucks K2500 Cheyenne Ext. Cab uses the wider 245/75R16 radial fitment. Tire choice is therefore more straightforward, with the main decision shifting to wheel-width compatibility, load needs, and whether the truck's stance and clearance remain appropriate if anything has been modified.
The 1991 Chevrolet Trucks K2500 Silverado can be fitted with either 225/75R16 or 245/75R16 radial tires. That makes it important to verify the actual wheel and tire combination on the truck so the replacement keeps the correct 16-inch fitment and matches the intended use.
The 1991 Chevrolet Trucks K2500 Silverado Ext. Cab uses 245/75R16 radial tires. With only one primary size in play for this sub-model, the buyer can focus on choosing the right all-terrain tire characteristics and confirming that the wheel width still suits the tire properly.
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 1991 Chevrolet Trucks K2500 Tires for Sale
Available 1991 Chevrolet Trucks K2500 tire choices center on BFGoodrich All Terrain TA KO2 radials in both primary 16-inch sizes. The comparison is straightforward, with raised white letter sidewalls, different rim-width ranges, and different load capacities shaping the decision between 225/75R16 and 245/75R16.
Common questions for the 1991 Chevrolet Trucks K2500 usually come down to the right tire size by sub-model, 16-inch rim fitment, radial tire selection, sidewall appearance, and the checks worth making before putting a work-ready or collector-era truck back on the road.
Tire Size & Fitment
What tire size fits a 1991 Chevrolet Trucks K2500?
The 1991 Chevrolet Trucks K2500 uses two primary tire sizes: 225/75R16 and 245/75R16. Both are radial tires for 16-inch rims, but the exact size depends on the sub-model. Cheyenne and Silverado can use either size, while Cheyenne Ext. Cab and Silverado Ext. Cab use 245/75R16.
That makes identification of the exact truck configuration the first step before choosing a replacement. It is also smart to confirm what is currently mounted, especially on older trucks that may have had wheel or tire changes over the years. Matching the proper size helps maintain appropriate proportions, load capability, and clearance.
What size rim does a 1991 Chevrolet Trucks K2500 use?
Both primary tire sizes used on the 1991 Chevrolet Trucks K2500 mount on 16-inch rims. The two listed fitments, 225/75R16 and 245/75R16, share the same rim diameter, so the main difference is tire width and overall size rather than wheel diameter.
Rim diameter is only part of the picture on a heavy-duty pickup. Wheel width should also be checked, since the available 225/75R16 and 245/75R16 products do not use the same rim-width range. A truck with aftermarket wheels, replacement steel wheels, or a changed suspension setup deserves a quick measurement before new tires go on.
Do all 1991 Chevrolet Trucks K2500 sub-models use the same tire size?
No, not all 1991 Chevrolet Trucks K2500 sub-models use the same tire size. Cheyenne and Silverado can use either 225/75R16 or 245/75R16, while the Cheyenne Ext. Cab and Silverado Ext. Cab use 245/75R16 as their listed fitment.
That difference matters because a broader size range on some trims does not mean every K2500 should be treated the same. The most reliable approach is to confirm the sub-model first, then verify the current wheel setup on the truck. That keeps the replacement centered on the correct 16-inch fitment and avoids choosing a tire by appearance alone.
Choosing the Right Tire
What should I consider when choosing a 1991 Chevrolet Trucks K2500 tire?
Start with the correct primary size for the truck: 225/75R16 or 245/75R16, depending on the sub-model and wheel setup. Both are radial 16-inch fitments, so the choice is less about construction type and more about selecting the right dimensions, load capacity, and wheel-width compatibility for how the K2500 is actually used.
The available tires also differ in measurable ways beyond size alone. Comparing max load figures, product weight, and recommended rim-width range helps narrow the best match for a truck that may still see hauling, towing, or rougher surface use. Keeping those practical details in line usually matters more than choosing by tread appearance alone.
What sidewall styles are available for 1991 Chevrolet Trucks K2500 tires?
The available 1991 Chevrolet Trucks K2500 products here use an RWL sidewall, which means raised white letters. That gives the truck a traditional all-terrain appearance that fits well with the square-body Chevrolet pickup look of the early 1990s.
Sidewall style is mostly an appearance decision once the correct size and wheel compatibility are confirmed, but it still changes how the truck presents itself. Raised white letters tend to emphasize the tire visually, especially on restored or well-kept pickups. If preserving a more subdued look matters, the buyer should focus first on size and construction, then compare sidewall treatment.
What brands offer tires for the 1991 Chevrolet Trucks K2500?
BFGoodrich is the brand offered for the 1991 Chevrolet Trucks K2500 in the currently available primary sizes. Both 225/75R16 and 245/75R16 appear in the All Terrain TA KO2 series, giving the truck a consistent radial all-terrain option across the fitments used here.
With one brand and one series represented, the main comparison shifts to the tire size itself rather than brand-to-brand differences. That keeps attention on whether the truck needs 225/75R16 or 245/75R16, along with rim-width range, load capacity, and the role the truck plays today. A K2500 used mainly on-road may be evaluated differently than one that still sees heavier work.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Chevrolet Trucks K2500?
A period-style 1991 Chevrolet Trucks K2500 tire choice starts with the correct primary size for the truck's sub-model and wheel setup, either 225/75R16 or 245/75R16. Since this truck uses radial 16-inch fitments, a size-correct radial with a traditional truck presentation is the best starting point for preserving the right overall look.
Appearance should be balanced against how the truck is used. A restoration-minded owner may care most about maintaining factory-era proportions, while a regularly driven K2500 may also need to prioritize load capacity and wheel compatibility. If originality is being judged closely, vehicle-specific literature or marque knowledge can help confirm whether the current tire look matches the intended presentation.
How does tire construction affect the appearance of a restored 1991 Chevrolet Trucks K2500?
Tire construction has less visual impact here than it would on a much older vehicle because the 1991 Chevrolet Trucks K2500 already uses radial tire sizes as its primary fitment. The more noticeable appearance differences come from the tire's overall size, sidewall treatment, tread character, and how full the tire looks within the wheel opening.
For a restored truck, keeping the correct radial size usually does more for the finished stance than chasing construction changes. A 225/75R16 and a 245/75R16 do not present the same footprint or visual fullness, so choosing the size that belongs with the truck's sub-model and wheel setup is important. Raised white letters also create a more assertive period truck look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Chevrolet Trucks K2500?
Yes, modifications can affect tire fitment on a 1991 Chevrolet Trucks K2500 even when the replacement tire is one of the correct primary sizes. Changes to wheel width, wheel offset, ride height, springs, steering components, or body clearance can all alter how a 225/75R16 or 245/75R16 sits and moves on the truck.
That matters most on older pickups that may have changed hands several times. A quick check of wheel dimensions, steering clearance, and fender space can prevent problems that a stock truck might not have. It is especially worthwhile when moving between the two listed sizes, since they do not share the same section width or overall diameter.
What should I inspect before driving a 1991 Chevrolet Trucks K2500 on new tires?
Before driving a 1991 Chevrolet Trucks K2500 on new tires, inspect the wheels for correct diameter and width, confirm lug hardware condition, and make sure the tires are inflated appropriately for the intended load. It also helps to look over the steering and suspension for looseness, uneven wear causes, and any signs of contact around the wheel openings.
A new tire cannot correct worn front-end parts or an incorrect wheel setup. After installation, check that the truck tracks properly, clears at full steering lock, and shows no rubbing under compression. On a K2500 that still works for a living, load capacity should be part of the pre-drive checklist rather than an afterthought.
How should 225/75R16 and 245/75R16 tires on a collector-era 1991 Chevrolet Trucks K2500 be maintained?
Tires on a collector-era 1991 Chevrolet Trucks K2500 should be maintained with regular pressure checks, visual inspections, and periodic evaluation for aging even if the truck is driven infrequently. Watch for cracking, cuts, bulges, irregular tread wear, and slow air loss, and keep the tires clean and protected from prolonged sunlight and harsh storage conditions.
Low annual mileage can hide tire problems on an older pickup, so condition matters just as much as tread depth. It also helps to move the truck occasionally or avoid long periods sitting on one spot to reduce flat-spotting. Before a longer trip, inspect the spare and confirm that all four road tires still match the intended size and service role.
