The 1991 Chevrolet Trucks C2500 sits in an era when Chevrolet heavy-duty pickups were expected to handle real work while still serving as everyday transportation. Buyers today often keep these trucks on the road for towing, hauling, weekend use, or preservation as honest square-body-era survivors. Tire fitment centers on two radial sizes, 225/75R16 and 245/75R16, both built around a 16-inch wheel. That makes the key decision less about vintage construction and more about choosing the right width, load-carrying capacity, and overall stance. For a truck that may have seen wheel changes over the years, confirming the exact size already on the vehicle remains an important first step.
Which Tire Size Is Right for The 1991 Chevrolet Trucks C2500
The 1991 Chevrolet Trucks C2500 uses two primary tire sizes, and both are radial tires designed for 16-inch rims. Cheyenne and Silverado sub-models can use either size, so the first thing to confirm is which wheel and tire combination is actually on the truck now. Once that is settled, the decision comes down to width, load capacity, rim compatibility, and the look and stance you want to maintain.
225/75R16 is a metric radial size in which 225 refers to the nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 16 is the rim diameter in inches. On a 1991 Chevrolet Trucks C2500, this size keeps the fitment in a modern radial format appropriate to the truck's original era. Available choices in this size include a BFGoodrich All Terrain TA KO2 with raised white letter sidewalls. It is a useful size to evaluate when maintaining a slightly narrower footprint on a 16-inch wheel with truck-duty capability.
245/75R16 is also a metric radial size, with a 245-millimeter nominal section width, a 75-series profile, radial construction, and a 16-inch rim requirement. For the 1991 Chevrolet Trucks C2500, it represents the wider of the two primary fitment choices and stays within the truck's radial tire context. This size is available in BFGoodrich's All Terrain TA KO2 line with raised white letter sidewalls. It is worth considering when the truck already carries the wider setup or when wheel width and intended use support the larger tire.
Tire fitment is fairly straightforward across the covered 1991 Chevrolet Trucks C2500 sub-models because both Cheyenne and Silverado use the same two radial size options. What matters most is confirming which 16-inch wheel and tire combination is on the individual truck before choosing a replacement.

1991 Chevrolet Trucks C2500 Cheyenne
The 1991 Chevrolet Trucks C2500 Cheyenne can use either of the two primary 16-inch radial tire sizes offered for this truck. That means tire selection depends less on trim name and more on confirming the current wheel width, the size already in use, and the load needs of the truck.
The 1991 Chevrolet Trucks C2500 Silverado also uses the same two 16-inch radial size options found on the broader model line. The practical choice is deciding whether the truck should stay with its current width or move only after checking wheel compatibility, stance, and working 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 1991 Chevrolet Trucks C2500?
The 1991 Chevrolet Trucks C2500 uses two primary tire sizes: 225/75R16 and 245/75R16. Both are radial tires built for 16-inch rims, and both Cheyenne and Silverado sub-models can use either size depending on the truck's wheel and tire setup.
That means the right choice is not determined by trim alone. The most useful next step is checking the truck's current tire sidewall and wheel width so the replacement size matches the setup already in service, along with the truck's intended hauling, towing, or general road use.
What size rim does a 1991 Chevrolet Trucks C2500 use?
The supported tire sizes for the 1991 Chevrolet Trucks C2500 both use a 16-inch rim diameter. That applies to 225/75R16 and 245/75R16 fitments, so confirming a 16-inch wheel is the starting point before comparing specific replacement tires.
Rim diameter is only part of the picture on a truck like this. Wheel width still matters, especially because the available 225/75R16 and 245/75R16 products have different rim-width ranges, so checking the actual wheel dimensions helps prevent choosing a tire that is correct in diameter but mismatched to the wheel.
Do all 1991 Chevrolet Trucks C2500 sub-models use the same tire size?
Cheyenne and Silverado share the same tire-size choices on the 1991 Chevrolet Trucks C2500. Each sub-model can use either 225/75R16 or 245/75R16, both in radial construction on a 16-inch rim.
Since the sub-models share the same size options, the real question becomes which combination is on the truck now. Many older pickups have had wheels changed over time, so checking the current tire size, wheel width, and overall clearance is more important than relying on the trim badge alone.
Choosing the Right Tire
What should I consider when choosing a tire for a 1991 Chevrolet Trucks C2500?
Start with the correct primary size for the truck, which will be either 225/75R16 or 245/75R16 on a 16-inch rim. Since both available options are radial truck tires, the main differences come down to tire width, load capacity, rim-width compatibility, and how the truck is actually used.
A C2500 that spends more time hauling or towing may call for a different choice than one used mostly for occasional cruising. It also helps to compare the current wheel setup and stance before changing widths, especially on a truck that may have seen aftermarket wheels or suspension changes over the years.
What sidewall styles are available for 1991 Chevrolet Trucks C2500 tires?
The available tire options for the 1991 Chevrolet Trucks C2500 use an RWL sidewall, meaning raised white letters. That gives these 16-inch radial truck tires a more traditional light-truck appearance than a plain blackwall sidewall treatment.
Sidewall style does not change the basic fitment, but it does affect the truck's visual presentation. Raised white letters tend to suit a period-style pickup look, so owners who want to preserve that character often weigh sidewall appearance alongside the more practical factors of size, wheel compatibility, and load rating.
What tire series are available for the 1991 Chevrolet Trucks C2500?
The available tire series for this fitment is the BFGoodrich All Terrain TA KO2. It is offered in both 225/75R16 and 245/75R16, giving the 1991 Chevrolet Trucks C2500 a consistent all-terrain radial option across the two primary sizes.
Because the series remains the same in both sizes, the main comparison shifts to dimensions and specifications rather than tread family. Checking rim-width range, load capacity, and the truck's current setup will help determine whether the narrower or wider version makes more sense for the way the C2500 is driven.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Chevrolet Trucks C2500?
A period-style 1991 Chevrolet Trucks C2500 should start with one of its correct primary radial sizes, either 225/75R16 or 245/75R16, depending on the truck's wheel setup. Staying with the right size family preserves the truck's overall proportions more effectively than choosing an unrelated modern size.
Appearance then comes down to details such as width and sidewall treatment. The available RWL presentation suits the visual character many early-1990s full-size pickups carried, but the better choice still depends on matching the existing wheels, maintaining usable clearance, and keeping the truck's stance in line with your restoration goals.
How does tire construction affect the appearance of a restored 1991 Chevrolet Trucks C2500?
On a 1991 Chevrolet Trucks C2500, tire construction is less of a vintage-versus-modern debate because the primary fitments are already radial. That means the truck's restored appearance is influenced more by the selected size, sidewall styling, and overall tire profile than by switching between bias-ply and radial construction.
A restoration-minded owner will usually get the cleanest result by keeping the tire visually appropriate to the truck's era and wheel package. Width changes can alter the stance noticeably, so it helps to compare the current setup carefully before changing from 225/75R16 to 245/75R16 or the reverse.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Chevrolet Trucks C2500?
Yes, modifications can affect tire fitment on a 1991 Chevrolet Trucks C2500 even when the tire size itself is one of the correct options. Wheel width changes, aftermarket offsets, suspension alterations, and body or steering clearance differences can all influence whether 225/75R16 or 245/75R16 remains the better choice.
An older truck often has a history that is not obvious at first glance. Measuring the wheels, checking clearance at full steering lock, and looking for signs of rubbing around suspension and fender areas will help confirm that the selected replacement tire matches the truck's current configuration rather than its original one.
What should I inspect before driving a 1991 Chevrolet Trucks C2500 on new tires?
Before driving a 1991 Chevrolet Trucks C2500 on new tires, inspect the wheels for correct diameter and width, check that the tires are inflated properly, and look over suspension and steering components for looseness or wear. Lug hardware, valve stems, and overall clearance should also be checked carefully.
A fresh set of tires cannot compensate for worn mechanical parts or wheel issues. It is smart to recheck clearance after installation, especially if the truck uses the wider 245/75R16 size, then monitor early wear patterns and air retention during the first several drives to catch setup problems quickly.
How should tires on a collector 1991 Chevrolet Trucks C2500 be maintained?
Tires on a collector 1991 Chevrolet Trucks C2500 should be kept at appropriate pressure, inspected regularly for cracking, cuts, bulges, and uneven wear, and monitored for slow air loss. Even a truck that is driven sparingly still needs routine tire attention because age and storage conditions affect rubber over time.
Long periods of sitting can be hard on any collector truck tire. Clean, dry storage away from prolonged sunlight and ozone sources helps preserve condition, and occasional checks of tread, sidewalls, and wheel hardware make it easier to spot problems before a local cruise, towing duty, or a longer highway run.
