The 1991 Chevrolet Trucks C3500 sits in the final years of Chevrolet’s square-body heavy-duty truck era, a period known for straightforward work-truck engineering and serious one-ton capability. In dual-rear-wheel form, these trucks are often kept for hauling, farm use, commercial service, or preservation as honest late-classic pickups. Tire selection centers on two 16-inch fitments: a modern 225/75R16 radial and a traditional 750-16 bias-ply. That opens the door to very different choices, from an all-terrain raised white letter radial to blackwall, wide whitewall, and truck-oriented bias-ply designs. The right direction depends on whether the truck’s priority is utility, restoration-style appearance, or maintaining the wheel and tire character already on the vehicle.
Which Tire Size Is Right for The 1991 Chevrolet Trucks C3500
The 1991 Chevrolet Trucks C3500 uses two primary tire sizes, and both mount on 16-inch wheels. Choosing the right one starts with confirming whether the truck is staying with a modern 225/75R16 radial setup or a 750-16 bias-ply setup, since construction, appearance, and intended use differ more than rim diameter here.
225/75R16 is a metric radial size where 225 identifies section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 16 is the wheel diameter in inches. On the 1991 Chevrolet Trucks C3500, this size represents the modern radial fitment path and is used on a 16-inch rim. Available choices in this size include a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls and a 6.0 to 7.0 inch rim-width range. It is the size to evaluate when the truck is set up for contemporary radial service and the owner wants a more modern truck-tire presentation.
750-16 is a numeric bias-ply size in which 7.50 refers to the nominal section width in inches and 16 identifies the wheel diameter. For the 1991 Chevrolet Trucks C3500, this size carries a traditional bias-ply look and opens up the broadest range of period-style and truck-oriented choices. Available options include Firestone, Lester, BFGoodrich, and STA products, with blackwall and wide whitewall sidewall treatments across classic bias-ply, military, highway, and traction-style series. It is the size to consider when preserving a more traditional appearance or matching an existing bias-ply wheel-and-tire setup.
Sub-model fitment on the 1991 Chevrolet Trucks C3500 is mostly straightforward, but it still helps to confirm whether the truck is identified as a full DRW model or by separate front and rear positions. The main distinction is that the complete DRW trim listings show both radial and bias-ply paths, while the front and rear position listings stay with the radial size.

The 1991 Chevrolet Trucks C3500 Cheyenne (DRW) is associated with both 225/75R16 radial and 750-16 bias-ply fitments on 16-inch wheels. Tire selection here depends on whether the truck is being kept in a more traditional bias-ply style or maintained with a modern radial setup.
The 1991 Chevrolet Trucks C3500 Cheyenne (DRW) Front uses the 225/75R16 radial size. That makes front tire selection more focused on choosing the right radial product and confirming that the wheel width and overall truck setup still match this modern metric fitment.
The 1991 Chevrolet Trucks C3500 Cheyenne (DRW) Rear also uses the 225/75R16 radial size. For rear tire selection, the main consideration is maintaining the correct radial setup and checking that the dual-wheel arrangement has the right wheel dimensions and spacing for the chosen tire.
The 1991 Chevrolet Trucks C3500 Silverado (DRW) is associated with both 225/75R16 radial and 750-16 bias-ply options on 16-inch rims. That gives the owner a clear choice between modern radial truck use and a more traditional bias-ply presentation with broader sidewall and series variety.
The 1991 Chevrolet Trucks C3500 Silverado (DRW) Front uses a 225/75R16 radial tire. Choosing among front tire options is mainly about selecting the radial design that suits the truck’s use and confirming compatibility with the wheel width already on the vehicle.
The 1991 Chevrolet Trucks C3500 Silverado (DRW) Rear uses a 225/75R16 radial tire as well. Rear tire choice should stay centered on the correct radial size while also checking dual-wheel clearance, matching tire type across the axle, and overall condition of the rear wheel setup.
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 C3500 Tires for Sale
Available 1991 Chevrolet Trucks C3500 tire choices split clearly between a BFGoodrich 225/75R16 radial all-terrain and a much broader group of 750-16 bias-ply options from Firestone, Lester, BFGoodrich, and STA. In 750-16, buyers can compare blackwall versus wide whitewall styling, classic bias-ply series, and heavier-duty truck-oriented designs.
Owners of a 1991 Chevrolet Trucks C3500 usually need to sort out size, 16-inch wheel fitment, radial versus bias-ply construction, sidewall style, and truck-use priorities before choosing a tire. These questions focus on the practical details that matter most on this exact C3500.
Tire Size & Fitment
What tire size fits a 1991 Chevrolet Trucks C3500?
The 1991 Chevrolet Trucks C3500 uses two primary tire sizes: 225/75R16 in radial construction and 750-16 in bias-ply construction. Both sizes are tied to 16-inch wheels, but they represent different tire formats and different approaches to how the truck is set up.
The practical choice is not just the number on the sidewall. It is also whether the truck is staying with a modern radial arrangement or a traditional bias-ply arrangement, and whether the current wheels match the intended tire. A DRW truck should also be checked carefully for correct wheel dimensions and dual-wheel spacing before changing tire type.
What size rim does a 1991 Chevrolet Trucks C3500 use?
The tire fitments associated with the 1991 Chevrolet Trucks C3500 use a 16-inch rim diameter. That applies to both the 225/75R16 radial size and the 750-16 bias-ply size, so the wheel diameter remains consistent even though the tire constructions differ.
Rim diameter is only part of the fitment picture. Wheel width still matters, especially because the available 225/75R16 product is tied to a 6.0 to 7.0 inch rim-width range, while several 750-16 bias-ply products are built around 5.00 to 6.00 inch wheels. Checking the actual wheel before selecting a tire helps avoid mismatching the construction to the rim.
Do all 1991 Chevrolet Trucks C3500 sub-models use the same tire size?
Not every 1991 Chevrolet Trucks C3500 sub-model is presented the same way. The Cheyenne (DRW) and Silverado (DRW) listings show both 225/75R16 radial and 750-16 bias-ply fitments, while the separate front and rear DRW position listings use 225/75R16 radial.
That means the exact sub-model or position matters before choosing a tire. A buyer looking at the complete DRW truck may be deciding between two fitment paths, while someone replacing front or rear tires by position is dealing with a radial-only listing. Matching the replacement to the truck’s current wheel-and-tire setup is the safest next step.
Bias-Ply & Radial Options
Is 750-16 a bias-ply or radial tire for the 1991 Chevrolet Trucks C3500?
On the 1991 Chevrolet Trucks C3500, 750-16 is a bias-ply tire size. It uses the older numeric sizing format and is available in traditional bias-ply styles ranging from classic blackwall and wide whitewall designs to truck and military-oriented tread patterns.
That matters because a bias-ply 750-16 has a different construction character and visual presence than a 225/75R16 radial, even though both use 16-inch rims. Before changing from one construction to the other, confirm the wheel width, check the truck’s current setup, and make sure the intended tire suits the way the C3500 will actually be used.
Should I use bias-ply or radial tires on a 1991 Chevrolet Trucks C3500?
Either construction can be relevant on a 1991 Chevrolet Trucks C3500, depending on the setup being maintained. The radial path here is 225/75R16, while the bias-ply path is 750-16. The decision usually comes down to whether the truck is being kept in a modern service style or a more traditional presentation.
A radial choice makes sense when the truck already uses the metric radial setup and the owner wants to stay with that arrangement. A bias-ply choice often suits restoration-minded use or a truck that already runs 750-16 tires. Wheel width, dual-wheel clearance, and consistency across the axle should all be checked before changing construction.
What should I check before converting my 1991 Chevrolet Trucks C3500 from bias-ply to radial tires?
Start by confirming that the truck’s wheels are correct for the radial size being considered, since the 1991 Chevrolet Trucks C3500 uses 225/75R16 as its radial fitment path. The wheel diameter may already be 16 inches, but width and the overall wheel setup still need to suit the radial tire.
A dual-rear-wheel truck adds another layer, because spacing between the rear tires and the exact wheel arrangement should be inspected before any conversion. It also helps to compare the current tire setup front to rear and make sure the suspension, steering clearance, and intended load use all align with the change rather than treating the switch as automatic.
Choosing the Right Tire
What should I consider when choosing a tire for a 1991 Chevrolet Trucks C3500?
Start with the truck’s actual fitment path: 225/75R16 radial or 750-16 bias-ply. That choice shapes nearly everything else, including construction, appearance, wheel-width compatibility, and whether the truck is being kept in a modern working setup or a more traditional heavy-duty presentation.
After size and construction are settled, compare the tire’s intended use and specifications. Some 750-16 products are classic-style blackwalls or wide whitewalls, while others are more truck-oriented with different load figures and series names. A 225/75R16 radial all-terrain points in a different direction entirely, so matching the tire to the truck’s purpose is essential.
What sidewall styles are available for 1991 Chevrolet Trucks C3500 tires?
Sidewall choices for the 1991 Chevrolet Trucks C3500 include raised white letter, blackwall, and wide whitewall depending on the tire size and product selected. The 225/75R16 radial option carries a raised white letter presentation, while 750-16 bias-ply options are offered in both blackwall and wide whitewall styles.
That makes sidewall style an important part of the decision, especially on a truck that may be restored, preserved, or shown as often as it is driven. A blackwall usually suits a more utilitarian look, a wide whitewall creates a stronger vintage visual statement, and raised white letters give the radial option a more modern truck appearance.
What brands offer tires for the 1991 Chevrolet Trucks C3500?
Tires for the 1991 Chevrolet Trucks C3500 are available from BFGoodrich, Firestone, Lester, and STA. BFGoodrich appears in both the 225/75R16 radial and 750-16 bias-ply fitments, while Firestone, Lester, and STA are represented among the 750-16 bias-ply choices.
Brand is only one part of the comparison. The more useful next step is looking at which series, sidewall treatments, and construction types each brand offers in the size the truck actually uses. On this C3500, that distinction matters because the radial choice is narrow, while the 750-16 bias-ply range covers several very different tire personalities.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Chevrolet Trucks C3500?
For a period-style 1991 Chevrolet Trucks C3500, the 750-16 bias-ply fitment is the more traditional starting point. That size is available in classic bias-ply and truck-oriented series, giving the truck a more vintage heavy-duty look than the 225/75R16 radial path.
Appearance goals still matter within that size. A blackwall 750-16 keeps the look more work-truck oriented, while a wide whitewall creates a much more stylized presentation. When exact originality is important, it is smart to compare the truck against marque references, surviving examples, or period documentation before settling on a brand or sidewall treatment.
How does tire construction affect the appearance of a restored 1991 Chevrolet Trucks C3500?
Tire construction changes the visual character of a restored 1991 Chevrolet Trucks C3500 in a noticeable way. A 750-16 bias-ply gives the truck a more traditional profile and opens the door to classic blackwall or wide whitewall styles, while the 225/75R16 radial presents a more modern truck look.
That visual difference can matter as much as the size itself on a late-classic pickup. Owners restoring a truck toward its earlier 1990s work-truck feel often focus on the bias-ply presentation, while owners preserving a later-service appearance may stay with the radial setup. The wheel width and overall stance should support whichever direction is chosen.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Chevrolet Trucks C3500?
Yes, modifications can affect tire fitment on a 1991 Chevrolet Trucks C3500 even when the tire size itself is correct. Changes to wheel width, wheel offset, suspension height, rear dual-wheel hardware, or brake components can alter how a 225/75R16 radial or 750-16 bias-ply sits on the truck.
That is especially important on a DRW truck, where inner and outer rear tire spacing needs to remain appropriate. An owner dealing with aftermarket wheels or suspension changes should check clearance at the fenders, steering range, and between dual rear tires before selecting replacements. The tire size alone does not confirm that a modified setup is still compatible.
What should I inspect before driving a 1991 Chevrolet Trucks C3500 on new tires?
Before driving a 1991 Chevrolet Trucks C3500 on new tires, inspect the wheels for damage, confirm the wheel size and width match the chosen tire, and make sure the tires are mounted and inflated correctly for their application. It also helps to verify that the front and rear positions are using the intended size and construction.
A heavy-duty older truck deserves a broader walk-around before road use. Look for rubbing at full steering lock, check dual-rear-wheel spacing, inspect valve stems, and confirm that suspension and steering components are in sound condition. After the first miles, recheck inflation and look for any signs that the tires are contacting the body or wheel hardware.
How should tires on a collector 1991 Chevrolet Trucks C3500 be maintained?
Tires on a collector 1991 Chevrolet Trucks C3500 should be kept properly inflated, inspected regularly, and protected from long periods of heat, sunlight, moisture, and ozone exposure. Even a truck that is driven only occasionally can develop aging issues such as cracking, flat spotting, air loss, or sidewall damage over time.
Regular checks matter more than mileage on many preserved trucks. Inspect tread and sidewalls before each outing, watch for bulges or cuts, and pay close attention to matching condition across a dual-rear-wheel setup. Clean, dry storage and periodic movement help, but any tire showing questionable age or structural condition deserves professional evaluation before road use.
