The 1988 Ford Trucks Bronco sits squarely in the era when full-size SUVs had become both everyday utility vehicles and highly recognizable weekend rigs. Buyers today often approach this Bronco with two different goals in mind: preserving its late-1980s character or leaning into its truck-based stance and road use. Tire fitment reflects that split, with 15-inch radial sizes including 235/75R15 and, on some sub-models, the larger 31X10.50R15. Available choices range from raised white letter all-terrain styling to narrow and wide whitewall radial options. The right selection starts with the exact sub-model and wheel setup, then balances appearance, size, and intended use.
Which Tire Size Is Right for The 1988 Ford Trucks Bronco
The 1988 Ford Trucks Bronco uses two primary tire sizes, and the correct choice depends on the sub-model. Both fitments are radial tires for 15-inch wheels, but they differ noticeably in overall size and presentation. The first step is confirming whether the Bronco is a Custom, Eddie Bauer, or XLT, then matching the tire to the wheel width and the way the vehicle is set up today.
235/75R15 is a metric radial size in which 235 identifies the nominal section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 15 is the wheel diameter in inches. On the 1988 Ford Trucks Bronco, this is one of the standard 15-inch radial fitments and is used across all covered sub-models. Product choices in this size include BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar, with RWL, narrow whitewall, and wide whitewall sidewall treatments. It suits buyers who want the broadest range of appearance options while staying within a stock-type size format.
31X10.50R15 is a flotation-style light truck radial size, with 31 referring to approximate overall tire diameter in inches, 10.50 to nominal section width, R to radial construction, and 15 to wheel diameter. On the 1988 Ford Trucks Bronco, this size applies to certain Eddie Bauer and XLT configurations rather than every sub-model. The available product in this fitment is a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, giving it a distinctly truck-oriented look. It is the size to evaluate when the Bronco needs the taller, wider 31-inch fitment and the wheel width matches that application.
Sub-model identification matters on the 1988 Ford Trucks Bronco because fitment is not the same across the range. The Custom uses one tire size, while Eddie Bauer and XLT models can use either of the two 15-inch radial sizes depending on the vehicle's wheel and tire setup.

1988 Ford Trucks Bronco Custom
The 1988 Ford Trucks Bronco Custom uses the 235/75R15 radial size. That keeps tire selection fairly straightforward, with the main decision centered on sidewall style, brand, and whether the Bronco is being kept in a stock-type appearance or given a more distinctive whitewall treatment.
The 1988 Ford Trucks Bronco Eddie Bauer can use either 235/75R15 or 31X10.50R15, both on 15-inch wheels. Selecting the right tire starts with confirming which wheel and tire combination is actually on the vehicle, since the two sizes create very different stance and use-case expectations.
The 1988 Ford Trucks Bronco XLT also spans both 235/75R15 and 31X10.50R15 radial fitments. That means tire choice is less about trim name alone and more about verifying the Bronco's current wheel width, existing tire size, and whether the vehicle remains in a stock-type 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 1988 Ford Trucks Bronco Tires for Sale
Available 1988 Ford Trucks Bronco tires center on radial 15-inch fitments from BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. The strongest comparison points are sidewall style, tire series, and whether the Bronco needs a stock-type 235/75R15 or the larger 31X10.50R15 all-terrain fitment.
Common 1988 Ford Trucks Bronco tire questions usually come down to size by sub-model, 15-inch wheel fitment, sidewall style choices, and what to inspect before putting a stock or modified Bronco back on the road.
Tire Size & Fitment
What tire size fits a 1988 Ford Trucks Bronco?
The 1988 Ford Trucks Bronco uses two primary radial tire sizes: 235/75R15 and 31X10.50R15. The Custom uses 235/75R15, while Eddie Bauer and XLT models can use either 235/75R15 or 31X10.50R15 depending on the specific setup.
That makes sub-model and wheel verification the first step before choosing a tire. A Bronco that currently wears aftermarket wheels, replacement suspension parts, or a different wheel width may not be best served by choosing only from the trim name, so the existing wheel diameter and actual mounted size should be checked before replacing tires.
What size rim does a 1988 Ford Trucks Bronco use?
Both primary tire sizes used on the 1988 Ford Trucks Bronco mount on 15-inch wheels. The 235/75R15 and 31X10.50R15 fitments share the same 15-inch rim diameter, even though the tires differ significantly in height and width.
Wheel diameter alone does not settle the fitment question, because wheel width still matters. Product specifications for 235/75R15 and 31X10.50R15 show different rim-width ranges, so a Bronco owner should confirm not just that the wheel is 15 inches, but that its width matches the tire being considered.
Do all 1988 Ford Trucks Bronco sub-models use the same tire size?
No. The 1988 Ford Trucks Bronco Custom uses 235/75R15, while the Eddie Bauer and XLT can use either 235/75R15 or 31X10.50R15. All of these are radial tires for 15-inch wheels, but the larger 31-inch fitment is not shared across every sub-model.
That difference matters because two Broncos from the same year can need very different replacement tires. Owners should check the exact sub-model and also confirm what is on the vehicle now, especially if it has spent years with replacement wheels or truck-style upgrades that may have changed the original-looking tire setup.
Choosing the Right Tire
What should I consider when choosing a 235/75R15 tire for a 1988 Ford Trucks Bronco?
Start with the fact that 235/75R15 is a primary radial fitment used across the 1988 Ford Trucks Bronco range, including the Custom and some Eddie Bauer and XLT setups. In this size, available choices vary by brand, tire series, sidewall style, rim-width specification, weight, and load capacity.
The practical choice depends on how the Bronco is used and how it should look. A raised white letter all-terrain presentation gives a different character than narrow or wide whitewalls, while wheel width should still be matched to the tire's approved range rather than assuming every 15-inch wheel is suitable.
What sidewall styles are available for 1988 Ford Trucks Bronco tires?
Sidewall choices for the 1988 Ford Trucks Bronco include RWL, narrow whitewall, and wide whitewall. The 235/75R15 size offers the broadest variety, while 31X10.50R15 is represented here by an RWL all-terrain tire.
That variety lets the tire do a lot of the visual work on the vehicle. An RWL tire leans toward a truck and off-road look, narrow whitewalls give a subtler custom touch, and wide whitewalls create a much more distinctive appearance, so the sidewall should match the Bronco's intended presentation rather than be treated as a minor detail.
What brands offer tires for the 1988 Ford Trucks Bronco?
Available brands for the 1988 Ford Trucks Bronco include BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. Most of that variety appears in 235/75R15, while the 31X10.50R15 option here is represented by BFGoodrich.
Brand matters mainly as part of the broader selection picture, not as a shortcut to the right tire. A buyer should still compare the exact size, sidewall treatment, tire series, load rating style, and wheel-width compatibility so the finished choice suits the Bronco's appearance and intended road use.
Restoration & Appearance
Which tire should I choose for a period-style 1988 Ford Trucks Bronco?
A period-style 1988 Ford Trucks Bronco choice starts with the correct primary size for the sub-model and wheel setup, then moves to the visual character of the tire. In 235/75R15, the Bronco has access to RWL, narrow whitewall, and wide whitewall radial options, while 31X10.50R15 presents a more truck-oriented all-terrain look.
That means the best appearance choice depends on the kind of late-1980s Bronco you are trying to represent. Buyers pursuing exact originality should compare the vehicle against period photos, dealer literature, or marque-specific references, while those aiming for a faithful era look can use the correct size and an appropriate sidewall style as the starting point.
How does tire construction affect the appearance of a restored 1988 Ford Trucks Bronco?
On the 1988 Ford Trucks Bronco, primary fitment stays within radial construction, so the appearance difference comes more from size, tread style, and sidewall treatment than from choosing between bias-ply and radial. A 235/75R15 whitewall presents very differently from a 31X10.50R15 raised white letter all-terrain tire.
That visual shift can change the Bronco from a stock-type late-1980s SUV impression to something more aggressively truck-styled. During a restoration, tire construction should still match the vehicle's intended use, but the most visible decisions will usually be whether to stay with the smaller metric fitment or move toward the taller 31-inch presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1988 Ford Trucks Bronco?
Yes. On a 1988 Ford Trucks Bronco, changes such as aftermarket wheels, different wheel widths, suspension lifts, lowering, or body trimming can all affect which tire size works properly. That is especially important when comparing 235/75R15 with the larger 31X10.50R15 fitment.
Even when the wheel diameter remains 15 inches, the tire's width and overall height still interact with steering clearance and fender space. A Bronco that has been altered from a stock-type setup should be measured carefully before replacement, so the new tires match the vehicle's actual wheel and suspension configuration.
What should I inspect before driving a 1988 Ford Trucks Bronco on new tires?
Before road use, inspect the wheels for correct diameter and condition, confirm lug hardware is appropriate, and make sure the tire size matches the Bronco's setup. It is also smart to check alignment-related wear patterns, brake condition, and whether the tires clear suspension and body components from lock to lock.
A collector or lightly used Bronco should also have its older rubber parts, shocks, and steering components looked over, since fresh tires can reveal play that was easy to ignore before. Proper inflation, a careful initial road test, and a recheck for rubbing or unusual wear help settle the new setup in safely.
How should 235/75R15 or 31X10.50R15 tires on a collector 1988 Ford Trucks Bronco be maintained?
Collector-use tires on a 1988 Ford Trucks Bronco should be kept properly inflated, inspected regularly for cracking, bulges, cuts, uneven wear, and slow air loss, and rotated when appropriate for the setup. A Bronco that sits for long periods needs tire condition checks even when the tread still looks deep.
Storage matters as much as mileage on an older SUV. Keeping the Bronco away from prolonged sun, excess heat, moisture, and ozone sources helps preserve the tires, while occasional movement prevents long stationary periods from becoming harder on the carcass than normal road use. Any sign of aging or structural distress deserves immediate attention.
