1989 Ford Trucks Bronco Tires

The 1989 Ford Trucks Bronco uses two primary tire sizes: 235/75R15 and 31X10.50R15. Both are radial tires built for 15-inch wheels, so the fitment question is not about bias-ply versus radial, but about confirming which of those two sizes belongs on the individual Bronco you are replacing tires on.

That matters because the two sizes do not represent the same tire profile or overall package. A Bronco may still have its original-style setup, or it may have been changed over time with different wheels, suspension height, or tire upgrades. Checking the current tire size, wheel width, and clearance before ordering helps avoid choosing the wrong 15-inch radial simply because both sizes are associated with the same year and model.

The tire fitments associated with the 1989 Ford Trucks Bronco use a 15-inch rim diameter. That is true for both 235/75R15 and 31X10.50R15, so the wheel diameter stays consistent even though the two tire sizes differ in section width and overall tire proportions.

Rim diameter is only part of the fitment picture, though. Product specifications within these sizes show different recommended rim-width ranges, so a 15-inch wheel still needs the right width for the tire being considered. Before replacing tires, confirm both the wheel diameter and the actual wheel width on the Bronco, especially if aftermarket wheels or a larger 31-inch tire setup may have been added at some point.

The 1989 Ford Trucks Bronco is associated with both 235/75R15 and 31X10.50R15 because this full-size SUV could appear with different wheel-and-tire setups while staying on a 15-inch rim. One size follows a more conventional metric radial format, while the other is a flotation-style light truck radial with a larger stated overall diameter and width.

For an owner, that means the right replacement starts with the Bronco in front of you rather than the trim badge alone. Custom, Eddie Bauer, and XLT can all be linked to either size, so the practical step is to read the current tires, confirm wheel width, and make sure the chosen size matches the truck’s present stance, clearance, and intended use.

Start by confirming whether the Bronco is using 235/75R15 or 31X10.50R15, since both are valid 15-inch radial fitments for this model. From there, compare the tire’s intended character, sidewall style, rim-width compatibility, and load specification. The available choices range from all-terrain raised white letter tires to classic-style radials with narrow or wide whitewalls.

The best choice depends on how the Bronco is set up and how it is meant to look and drive. A truck kept close to a stock-style road setup may point one direction, while a Bronco already wearing a 31-inch tire package points another. Matching the tire to the existing wheels, appearance goal, and real-world use usually matters more than the trim name alone.

Sidewall choices for the 1989 Ford Trucks Bronco include raised white letter, narrow whitewall, and wide whitewall designs. Raised white letter appears on the BFGoodrich all-terrain offerings, while 235/75R15 also opens the door to several classic radial options with whitewall treatments that range from subtle to much more pronounced.

That sidewall decision changes the Bronco’s presentation almost as much as the tire size itself. Raised white letter gives a more truck-oriented late-1980s look, while narrow and wide whitewalls can push the vehicle toward a custom, restoration-inspired, or cruiser style. Once the correct size is confirmed, sidewall choice becomes one of the clearest ways to match the tire to the Bronco’s appearance.

Tires for the 1989 Ford Trucks Bronco are available from BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. Brand choice varies by size, with 235/75R15 offering the broadest spread of options and 31X10.50R15 represented here by a BFGoodrich all-terrain raised white letter tire.

Brand matters mainly because it often aligns with a certain style of tire rather than changing the basic fitment rules. Some options lean toward classic whitewall presentation, while others emphasize light truck appearance and all-terrain character. After confirming the correct size, compare each brand’s series, sidewall treatment, rim-width range, and load figures to narrow the field in a practical way.

A period-style choice for a 1989 Ford Trucks Bronco depends on which of the two primary sizes the truck is already set up to use. In 235/75R15, the available radials include both raised white letter and multiple whitewall options, while 31X10.50R15 takes the Bronco toward a more truck-oriented all-terrain look on the same 15-inch rim diameter.

That gives a restoration-minded owner room to shape the truck’s character without leaving the correct year-and-model fitment path. A more original-feeling appearance may call for staying close to the existing size and sidewall style already associated with the Bronco. If exact historical accuracy matters beyond general period style, compare against marque references, photos, or original vehicle paperwork before committing.

For the 1989 Ford Trucks Bronco, the primary fitments are radial in both available sizes, so the appearance question is less about choosing bias-ply or radial and more about how the radial tire is styled. In practice, sidewall treatment and overall tire size do most of the visual work here, from raised white letters to narrow or wide whitewalls.

That means a restored Bronco can look very different even while remaining within the correct radial fitment family. A 235/75R15 whitewall radial creates a far different impression than a 31X10.50R15 raised white letter all-terrain. For appearance-focused projects, match the tire not just to the wheel diameter, but to the truck’s stance, trim level presentation, and the era-specific look you want to preserve.

Yes. Even though the 1989 Ford Trucks Bronco is associated with 235/75R15 and 31X10.50R15 on 15-inch wheels, modifications can change which tire works properly on a specific truck. Aftermarket wheels, altered wheel width, suspension lifts, lowering, steering changes, or body trimming can all affect how much room the tire has.

That is especially important when moving between the standard metric radial and the larger flotation-style size. A Bronco with changed wheels may still have the correct diameter but an unsuitable width for a given tire. Before replacing anything, inspect the current setup closely and make sure wheel width, tire clearance, and steering travel all agree with the size you intend to run.

Before putting a 1989 Ford Trucks Bronco into regular road use on new tires, inspect the wheels for the correct 15-inch diameter and suitable width, then confirm that the installed tire size matches the Bronco’s actual setup. It also helps to check suspension components, steering travel, and visible clearance around the fenders and inner wheelhouses.

After installation, keep an eye on inflation pressure, bead seating, and any signs of rubbing during turns or suspension movement. On an older full-size SUV, it is also wise to inspect shocks, springs, and front-end components that can influence how the tire sits and behaves. A short local test drive followed by a second visual inspection can catch fitment issues before longer trips.

Tires on a collector 1989 Ford Trucks Bronco should be inspected regularly even if the truck is not driven often. Check for cracking, cuts, bulges, irregular wear, and gradual air loss, and keep inflation pressure consistent with the tire being used. Low annual mileage does not stop tires from aging, especially on a heavier truck-based vehicle.

Storage conditions matter almost as much as mileage. Keeping the Bronco away from prolonged sunlight, heat, standing moisture, and ozone sources helps preserve the tires, whether it wears all-terrain raised white letter radials or a whitewall setup. It also helps to move the truck occasionally so the tires are not parked in one spot for long periods while carrying the full vehicle weight.
