The 1985 Jeep Trucks Grand Wagoneer sits in the heart of the full-size Jeep luxury 4x4 era, blending wagon utility with upscale trim that helped define the premium sport-utility formula before it became mainstream. Buyers looking after one today often care just as much about stance and appearance as everyday drivability. This model uses a 225/75R15 radial on a 15-inch rim, so the fitment question is straightforward. The real choice comes in sidewall presentation, with wide whitewall and narrow whitewall options available across several radial tire lines and brands. For a restoration-minded truck or a road-going survivor, matching the tire’s look to the vehicle’s character matters just as much as getting the size right.
Which Tire Size Is Right for The 1985 Jeep Trucks Grand Wagoneer
The 1985 Jeep Trucks Grand Wagoneer uses one primary tire size: 225/75R15. It is a radial fitment on a 15-inch rim, and that same size carries across both the Base and Limited sub-models. Because the size itself is consistent, the real decision is choosing the right radial tire within that fitment, including sidewall style, tire series, brand, and wheel-width compatibility.
225/75R15 is a metric radial size in which 225 identifies the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 15 is the rim diameter in inches. On the 1985 Jeep Trucks Grand Wagoneer, this modern radial format suits a vehicle that often sees regular road use as well as collector attention. Available choices include BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar, with both wide whitewall and narrow whitewall presentations. That makes this size easy to tailor toward either a more formal restoration-oriented look or a practical driver setup while staying within the correct fitment.
Tire fitment is uncomplicated across the covered 1985 Grand Wagoneer sub-models. Both use the same 225/75R15 radial size, so checking the sub-model mostly helps confirm that the vehicle still has the expected 15-inch wheel setup before choosing among the available tire styles.

The 1985 Jeep Trucks Grand Wagoneer Base uses the same 225/75R15 radial fitment as the rest of the model range. That means tire selection centers on sidewall appearance, brand, and wheel-width compatibility rather than sorting through different primary sizes.
The 1985 Jeep Trucks Grand Wagoneer Limited also uses 225/75R15 radial tires on a 15-inch rim. For this sub-model, the buying decision is less about fitment variation and more about choosing the whitewall style and tire series that best match the truck’s presentation and intended 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 1985 Jeep Trucks Grand Wagoneer?
The 1985 Jeep Trucks Grand Wagoneer uses a 225/75R15 radial tire. That is the primary size for this model, and it applies across the covered Grand Wagoneer sub-models rather than changing from one trim to another.
That consistency makes size selection simple, but it is still smart to confirm that the truck still has its 15-inch wheels and has not been changed to an aftermarket setup. Once the wheel size is confirmed, the next decisions are sidewall style, brand, and whether the tire’s rim-width specification matches the wheel on the vehicle.
What size rim does a 1985 Jeep Trucks Grand Wagoneer use?
The primary tire fitment for the 1985 Jeep Trucks Grand Wagoneer is built around a 15-inch rim. The 225/75R15 size uses that 15-inch diameter, which is the key wheel measurement that must match before any tire in this size can be considered.
Rim diameter is only part of the picture, though. Product options in 225/75R15 also carry their own rim-width specifications, such as 6 to 7.5 inches, 6.00 to 8.00 inches, or 6J, so it helps to measure the actual wheel before choosing among available tires. That check matters even more if the Grand Wagoneer has replacement wheels.
Do all 1985 Jeep Trucks Grand Wagoneer sub-models use the same tire size?
Yes. The covered 1985 Jeep Trucks Grand Wagoneer sub-models use the same 225/75R15 radial tire size. Both the Base and Limited versions share that fitment, so there is no sub-model split that forces you into a different primary size.
Even with shared sizing, it still helps to look closely at the truck’s current wheel and tire package before replacing anything. A Grand Wagoneer that has been modified over the years may no longer wear the expected wheels, and that can affect rim-width compatibility, sidewall appearance, and clearance. Confirming the actual setup prevents avoidable fitment mistakes.
Choosing the Right Tire
What should I consider when choosing a 225/75R15 tire for a 1985 Jeep Trucks Grand Wagoneer?
Start with the basics: correct size, radial construction, and 15-inch rim diameter. From there, compare each 225/75R15 tire by sidewall style, rim-width specification, brand, tire series, and other details such as load figures and overall presentation.
A Grand Wagoneer often benefits from a tire that looks right on the vehicle as much as one that simply matches the size code. Wide whitewall and narrow whitewall options create very different visual results, and wheel compatibility still matters. Matching the tire to the truck’s actual wheel dimensions and intended use helps narrow the field quickly.
What sidewall styles are available for 1985 Jeep Trucks Grand Wagoneer tires?
The available 225/75R15 tires for a 1985 Jeep Trucks Grand Wagoneer include both wide whitewall and narrow whitewall styles. Wide whitewall options include 2.75-inch whitewalls, while narrow whitewall choices include 1.60-inch, 1.6-inch, 0.75-inch, and 18mm whitewall presentations.
That choice affects the truck’s overall look more than many buyers expect. A wider whitewall tends to lean toward a more formal, restoration-oriented presentation, while a narrower whitewall gives a subtler appearance. Once the visual direction is settled, compare the wheel-width specifications and tire series details so the look and fitment work together.
What brands offer tires for the 1985 Jeep Trucks Grand Wagoneer?
225/75R15 tires for the 1985 Jeep Trucks Grand Wagoneer are available from BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar. The lineup includes multiple radial tire series, including Silvertown Radial, Star Series, American Classic Radial, and Travelstar UN106.
Brand alone should not decide the purchase. It makes more sense to compare which sidewall style each brand offers, how the tire series fits the vehicle’s look, and whether the wheel on the Jeep falls within the tire’s approved rim-width range. That approach helps keep the choice grounded in fitment and appearance rather than just name recognition.
Restoration & Appearance
Which tire should I choose for a period-style 1985 Jeep Trucks Grand Wagoneer?
A period-style 1985 Jeep Trucks Grand Wagoneer starts with the correct 225/75R15 size and a radial construction that suits the vehicle’s original era. From there, the strongest visual choice usually comes down to whether a wide whitewall or narrow whitewall better matches the truck’s trim, color, and intended presentation.
A wide whitewall can give the Grand Wagoneer a more formal luxury-wagon look, while a narrow whitewall tends to feel more understated. Exact originality questions can vary by vehicle history and restoration goals, so buyers pursuing a highly authentic result should compare the tire’s appearance against period photos, build documentation, or marque-specific references before deciding.
Does correct tire fitment matter for a 1985 Jeep Trucks Grand Wagoneer restoration?
Yes, correct tire fitment matters because the tire has a major effect on the Grand Wagoneer’s stance, proportions, and overall presentation. Using the proper 225/75R15 size keeps the wheel-to-tire relationship in the right range and gives the restoration a more cohesive, era-appropriate look.
Appearance is only part of the reason to stay disciplined about fitment. The wrong size or an incompatible wheel can create clearance concerns, alter the visual balance of the truck, or force compromises in sidewall style. A restoration-oriented approach works best when size, wheel dimensions, and sidewall presentation are all considered together rather than separately.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1985 Jeep Trucks Grand Wagoneer?
Yes. A 1985 Jeep Trucks Grand Wagoneer may have wheel, suspension, or ride-height changes that affect how a 225/75R15 tire works on the vehicle. Even when the size itself is correct, aftermarket wheels can change width or offset enough to alter fitment behavior.
Checking the actual wheel dimensions before replacement is the safest approach, especially on an older Jeep that may have been altered over time. It also helps to inspect fender and steering clearance at full lock and look for signs of rubbing. That extra step matters more than the trim level, since Base and Limited share the same primary size.
What should I inspect before driving a 1985 Jeep Trucks Grand Wagoneer on new tires?
Before road use, inspect wheel condition, lug hardware, valve stems, and overall tire pressure. It is also wise to look over the suspension and steering for looseness, since a new set of tires can reveal issues that were less noticeable with worn or aged tires.
A collector-era truck should also be checked for rubbing, uneven ride height, and any mismatch between the wheel on the vehicle and the tire’s approved rim-width range. After the first short drive, recheck pressure and look for any signs of contact or irregular wear. Those simple steps help the 225/75R15 fitment perform as intended.
How should 225/75R15 tires on a collector 1985 Jeep Trucks Grand Wagoneer be maintained?
Collector-use 225/75R15 tires should be maintained with regular pressure checks, visual inspections, and attention to age-related condition. Low-mileage vehicles are not exempt from tire deterioration, so sidewall cracking, bulges, cuts, flat spotting, and slow air loss deserve as much attention as tread wear.
Storage conditions matter too. Keeping the Grand Wagoneer away from prolonged sunlight, heat, moisture, and ozone sources can help preserve the tires between drives. It also helps to move or drive the vehicle periodically so the tires are not left supporting weight in one position for long periods, especially when the Jeep sees seasonal use.
