The 1991 Dodge Trucks Ramcharger came at the end of the full-size two-door SUV era, combining truck-based durability with the shorter-wheelbase character that made these models appealing for both daily use and recreational driving. For tire selection, that matters because this Ramcharger uses radial fitments on 15-inch wheels, with most sub-models running 235/75R15 while the w/Snow Pkg. uses 31X10.50R15. That opens up very different choices, from all-terrain raised white letter styling to wide and narrow whitewall radial options in the standard size. The right decision starts with confirming the exact sub-model and then matching the tire’s look and use to the vehicle’s current wheel and suspension setup.
Which Tire Size Is Right for The 1991 Dodge Trucks Ramcharger
Two primary tire sizes apply to the 1991 Dodge Trucks Ramcharger, and the difference comes down to sub-model rather than wheel diameter. Both sizes are radial tires for 15-inch rims, so the first step is confirming whether the vehicle is a Base, Canyon Sport, Royal SE, or w/Snow Pkg. model before comparing tread style, sidewall appearance, and wheel-width compatibility.
235/75R15 is a metric radial size in which 235 identifies the nominal section width in millimeters, 75 is the aspect ratio, and 15 is the wheel diameter in inches. On the 1991 Dodge Trucks Ramcharger, this is the standard radial fitment used on the Base, Canyon Sport, and Royal SE sub-models. Available choices range from BFGoodrich all-terrain raised white letter tires to restoration-oriented whitewall radials from American Classic, Coker Classic, BFGoodrich Silvertown, Maxxis, Tornel, and Travelstar. This size is the one to focus on if your Ramcharger keeps the standard 15-inch setup and you want the broadest mix of appearance and use-oriented options.
31X10.50R15 is a flotation-style radial size that expresses the tire’s overall diameter and section width more directly than a standard metric passenger size, with a 31-inch outside diameter, 10.50-inch section width, and 15-inch rim diameter. On the 1991 Dodge Trucks Ramcharger, this size is tied to the w/Snow Pkg. configuration rather than the other sub-models. The available product focus here is a BFGoodrich All-Terrain T/A KO2 with raised white letter styling, giving this fitment a distinctly truck-oriented presentation. This is the size to evaluate when the vehicle has the snow-package wheel and tire setup and you want to preserve that larger-format radial fitment.
Sub-model fitment matters on the 1991 Dodge Trucks Ramcharger because most versions share one size, while the w/Snow Pkg. uses a different radial fitment. Identifying the exact sub-model keeps the tire search centered on the correct size before comparing whitewall, raised white letter, or all-terrain options.

1991 Dodge Trucks Ramcharger Base
The 1991 Dodge Trucks Ramcharger Base uses the standard 235/75R15 radial fitment on a 15-inch wheel. That gives the buyer the widest selection on this vehicle, including truck-style raised white letter tires as well as narrow and wide whitewall radials.
The 1991 Dodge Trucks Ramcharger Canyon Sport also uses 235/75R15 radial tires on 15-inch rims. Tire selection here is less about finding a different fitment and more about choosing the right sidewall style, series, and wheel-width match for the vehicle’s intended look and use.
The 1991 Dodge Trucks Ramcharger Royal SE shares the 235/75R15 radial size used by the other standard Ramcharger trims. That keeps fitment straightforward, so the main decision becomes whether to stay with a truck-oriented RWL tire or choose one of the available whitewall radial styles.
The 1991 Dodge Trucks Ramcharger w/Snow Pkg. uses the larger 31X10.50R15 radial fitment on a 15-inch rim. That makes wheel-width confirmation more important, since this configuration follows a different tire format and a more specialized all-terrain style than the standard sub-models.
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 Dodge Trucks Ramcharger Tires for Sale
Available Ramcharger tire choices center on 235/75R15 and 31X10.50R15 radials, with BFGoodrich, American Classic, Coker Classic, Maxxis, Tornel, and Travelstar represented. The main differences are all-terrain versus classic radial series, raised white letter versus narrow or wide whitewall styling, and wheel-width compatibility across the 15-inch fitments.
Common 1991 Dodge Trucks Ramcharger tire questions usually come down to sub-model fitment, 15-inch wheel compatibility, sidewall style choices, and how to match a standard or snow-package setup to the vehicle’s intended use.
Tire Size & Fitment
What tire size fits a 1991 Dodge Trucks Ramcharger?
A 1991 Dodge Trucks Ramcharger uses one of two radial tire sizes, depending on sub-model. Base, Canyon Sport, and Royal SE models use 235/75R15, while the Ramcharger w/Snow Pkg. uses 31X10.50R15. Both fitments are built around a 15-inch wheel, but they are not the same overall tire size or format.
The practical step is identifying the exact sub-model and then confirming the wheel already on the vehicle. Many older SUVs have seen wheel, suspension, or tire changes over time, so matching the current setup matters just as much as knowing the original fitment path for that version of the Ramcharger.
What size rim does a 1991 Dodge Trucks Ramcharger use?
The 1991 Dodge Trucks Ramcharger uses 15-inch rims with both of its primary tire sizes. The standard 235/75R15 fitment and the larger 31X10.50R15 snow-package fitment are both designed around a 15-inch wheel diameter, even though the tires themselves differ in width and overall profile.
Wheel diameter is only part of the fitment picture, especially on a truck-based SUV. Rim width also matters when choosing among available tires, since 235/75R15 products and the 31X10.50R15 all-terrain option have different wheel-width ranges. Checking the actual wheel before purchase helps avoid a mismatch between tire shape and wheel dimensions.
Do all 1991 Dodge Trucks Ramcharger sub-models use the same tire size?
No. The 1991 Dodge Trucks Ramcharger Base, Canyon Sport, and Royal SE use 235/75R15 radial tires, while the 1991 Dodge Trucks Ramcharger w/Snow Pkg. uses 31X10.50R15 radial tires. That means fitment is mostly consistent across the standard trims, but the snow-package version follows a different size path.
That difference changes more than the sidewall marking. It affects the tire format, the available product selection, and the wheel-width range you need to verify. A buyer comparing Ramcharger tires should start by confirming whether the vehicle is a standard trim or the snow-package model before narrowing down brand, sidewall style, or tread type.
Choosing the Right Tire
What should I consider when choosing a 235/75R15 tire for a 1991 Dodge Trucks Ramcharger?
Start with the vehicle’s role and appearance goals. On a 1991 Dodge Trucks Ramcharger, 235/75R15 is used on the Base, Canyon Sport, and Royal SE, and the available options include all-terrain raised white letter tires as well as narrow and wide whitewall radials in several classic-oriented series.
Selection becomes easier once the use case is clear. A truck-style look may point toward the BFGoodrich all-terrain option, while a more vintage or custom presentation may favor one of the whitewall radials. Wheel width should also be checked, since the available 235/75R15 products do not all share the exact same rim-width specification.
What sidewall styles are available for 1991 Dodge Trucks Ramcharger tires?
Sidewall choices for the 1991 Dodge Trucks Ramcharger include raised white letter, narrow whitewall, and wide whitewall styles. The 235/75R15 fitment offers the broadest appearance range, while the 31X10.50R15 snow-package fitment is represented by a raised white letter all-terrain radial.
That gives the Ramcharger owner a clear visual decision to make before drilling into product details. Raised white letter sidewalls lean toward a more truck-oriented presentation, while narrow and wide whitewalls shift the look in a more classic or custom direction. The right choice depends on how the vehicle is finished and how it is meant to be used.
What brands offer tires for the 1991 Dodge Trucks Ramcharger?
Tires for the 1991 Dodge Trucks Ramcharger are available from BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. Brand coverage is strongest in the 235/75R15 size, while the 31X10.50R15 fitment is represented by BFGoodrich in an all-terrain radial with raised white letter styling.
Brand choice should be treated as one part of a broader fitment decision, not the only deciding factor. It helps to compare the tire series, sidewall presentation, load figures, and wheel-width compatibility within the correct size for the sub-model. That approach keeps the focus on the Ramcharger’s actual setup instead of shopping by name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Dodge Trucks Ramcharger?
A period-style 1991 Dodge Trucks Ramcharger tire choice starts with the correct size for the sub-model, then moves to the visual character of the tire. Standard trims using 235/75R15 have the widest appearance range, including raised white letter, narrow whitewall, and wide whitewall radials across several classic-oriented series.
The right look depends on how the Ramcharger is being presented. A more truck-focused restoration may favor raised white letters, while a custom or classic street presentation may lean toward a whitewall radial. Exact originality questions should be checked against marque-specific reference material, since size alone does not prove a particular sidewall treatment.
How does tire construction affect the appearance of a restored 1991 Dodge Trucks Ramcharger?
On the 1991 Dodge Trucks Ramcharger, the primary fitments are radial tires, so the visual effect comes less from choosing between bias-ply and radial construction and more from the tire format and sidewall design. A 235/75R15 radial can look very different depending on whether it carries raised white letters, a narrow whitewall, or a wide whitewall.
That means appearance decisions should be made with the whole vehicle in mind, including wheel style, ride height, and intended era feel. The w/Snow Pkg. fitment in 31X10.50R15 also creates a more substantial truck-oriented visual stance than the standard-size tires, so preserving the correct sub-model fitment has a noticeable effect on the finished look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Dodge Trucks Ramcharger?
Yes. A 1991 Dodge Trucks Ramcharger may have had wheel, suspension, or ride-height changes over the years, and those modifications can affect whether a tire still matches the vehicle correctly. That matters even more when comparing the standard 235/75R15 setup with the larger 31X10.50R15 fitment used on the w/Snow Pkg. model.
Clearance at the fender, steering components, and suspension travel should be checked any time the truck no longer sits on its original-style wheel and tire package. Wheel width also deserves attention, since available Ramcharger tires in these sizes call for different rim-width ranges and may not suit every aftermarket wheel equally well.
What should I inspect before driving a 1991 Dodge Trucks Ramcharger on new tires?
Before road use, inspect the wheels for the correct 15-inch diameter and suitable width for the chosen tire, then check inflation, valve stems, and overall clearance. It is also worth looking over suspension and steering components so the new tires are not being asked to work around worn parts on an older truck-based chassis.
A short test drive should confirm that the Ramcharger tracks properly and does not rub at full steering lock or over suspension movement. After a brief run, recheck pressure and look for any signs of interference. That extra step is especially helpful on vehicles that have sat for long periods or no longer wear their original wheel setup.
How should tires on a collector 1991 Dodge Trucks Ramcharger be maintained?
Collector-vehicle tire care for a 1991 Dodge Trucks Ramcharger starts with regular pressure checks, visual inspections, and attention to age-related deterioration. Even if tread depth looks good, an older tire can still develop cracking, flat-spotting, bulges, or other issues from long storage, sun exposure, or simple time in service.
Routine inspection matters more on vehicles that are driven occasionally than on daily transportation. Keeping the Ramcharger stored away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, and moving the vehicle periodically can reduce stress from sitting. Any sign of persistent air loss, sidewall damage, or vibration deserves immediate attention before road use.
