The 1989 Toyota Trucks 4Runner sits at an interesting point in the model’s development, when Toyota’s compact SUV had already earned a reputation for durability, off-road use, and everyday practicality. Buyers restoring or maintaining one today often want the tire choice to match how the truck is actually used, whether that means a more stock-style road setup or a tougher utility look. This 4Runner uses radial tires on 15-inch rims, with 225/75R15 and 31X10.50R15 both associated with the model. That creates a real choice between a conventional metric radial and a larger flotation-style light truck size. The right selection starts with confirming the truck’s exact setup and the appearance and use you want from it.
Which Tire Size Is Right for The 1989 Toyota Trucks 4Runner
The 1989 Toyota Trucks 4Runner uses two primary tire sizes, and both are radial tires for 15-inch rims. Because both the DLX and SR5 are associated with 225/75R15 and 31X10.50R15, the key step is confirming the actual wheel-and-tire setup on the vehicle before choosing a replacement. Once that is settled, the decision becomes one of profile, appearance, and intended use.
225/75R15 is a metric radial size in which 225 is the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 15 is the wheel diameter in inches. On a 1989 Toyota Trucks 4Runner, it represents the more conventional road-oriented sizing format used on a 15-inch rim. Available choices in this size include BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar, with narrow whitewall and wide whitewall sidewall treatments. It is the size to evaluate when the goal is a standard metric fitment and a more traditional overall presentation.
31X10.50R15 is a flotation-style radial size that states the tire’s approximate overall diameter first, then its nominal section width, followed by the 15-inch rim diameter. For the 1989 Toyota Trucks 4Runner, this size points to a larger, wider light truck fitment than the metric 225/75R15 option. The available product in this size is a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, giving it a more utility-focused appearance. This is the size to review when the truck already wears a larger 15-inch setup and clearance, wheel width, and intended use need to be checked carefully.
Tire fitment is straightforward across the covered 1989 Toyota Trucks 4Runner sub-models, because both DLX and SR5 are associated with the same two radial tire sizes. The important step is not choosing between trims, but confirming which 15-inch wheel-and-tire setup is actually on the truck now.

1989 Toyota Trucks 4Runner DLX
The 1989 Toyota Trucks 4Runner DLX is associated with both 225/75R15 and 31X10.50R15 radial tires on 15-inch rims. Tire selection comes down to verifying which setup the truck currently uses and then choosing the sidewall style, tread character, and overall look that best suits the vehicle.
The 1989 Toyota Trucks 4Runner SR5 is also associated with 225/75R15 and 31X10.50R15 radial tires on 15-inch rims. That means the practical decision is to confirm the wheel and tire combination already fitted, then choose between a more conventional metric radial presentation or a larger light truck style.
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 1989 Toyota Trucks 4Runner?
The 1989 Toyota Trucks 4Runner is associated with two radial tire sizes: 225/75R15 and 31X10.50R15. Both use a 15-inch rim, and both the DLX and SR5 sub-models are tied to those same sizes rather than having trim-specific tire sizes.
That means the real fitment question is not simply trim level, but which wheel-and-tire setup is currently on the truck. Checking the existing tire size, wheel width, and available clearance is especially important before moving between the narrower metric size and the larger flotation-style light truck size.
What size rim does a 1989 Toyota Trucks 4Runner use?
The 1989 Toyota Trucks 4Runner uses 15-inch rims with both of its associated tire sizes. The 225/75R15 radial and the 31X10.50R15 radial each mount on a 15-inch wheel, even though the two sizes differ significantly in overall profile and section width.
Rim diameter is only the first checkpoint, since wheel width also matters when comparing available tires. A 15-inch wheel does not automatically mean either size is suitable on every truck, so it helps to confirm the actual wheel dimensions and the truck’s present stance before ordering replacements.
Do all 1989 Toyota Trucks 4Runner sub-models use the same tire size?
The covered 1989 Toyota Trucks 4Runner sub-models share the same tire-size range. Both the DLX and SR5 are associated with 225/75R15 and 31X10.50R15 radial tires, so tire fitment does not separate cleanly by those two trim names.
That shared fitment means the deciding factor is the setup on the individual truck rather than the badge on the tailgate. A quick look at the current tires and wheels will usually tell you whether the 4Runner is using the standard metric-style size or the larger flotation-style radial.
Choosing the Right Tire
What should I consider when choosing a 225/75R15 or 31X10.50R15 tire for a 1989 Toyota Trucks 4Runner?
Start with the tire size already on the 1989 Toyota Trucks 4Runner. 225/75R15 is a conventional metric radial choice, while 31X10.50R15 is a larger flotation-style radial that brings a different overall stance, width, and product character even though both use 15-inch rims.
After confirming size, compare the available tire’s rim-width range, load capacity, sidewall style, and intended look. A truck kept for stock-style road use may point toward the metric radial options, while a 4Runner already set up around a larger utility or off-road presentation may call for the wider light truck fitment.
What sidewall styles are available for 1989 Toyota Trucks 4Runner tires?
Sidewall choices for the 1989 Toyota Trucks 4Runner include wide whitewall, narrow whitewall, and raised white letter styling. The whitewall treatments appear in 225/75R15 options, while the 31X10.50R15 all-terrain offering uses raised white letter sidewalls for a more truck-oriented presentation.
That makes sidewall style an important part of the decision, not just a cosmetic afterthought. A whitewall radial can push the truck toward a custom or vintage-inspired look, while raised white letters suit a more rugged late-1980s utility appearance, so the best choice depends on how the 4Runner is being finished and driven.
What brands offer tires for the 1989 Toyota Trucks 4Runner?
Tires for the 1989 Toyota Trucks 4Runner are available from BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar. Brand choice is concentrated in the 225/75R15 size, while the 31X10.50R15 option is represented by a BFGoodrich all-terrain tire.
Brand alone should not drive the decision. It makes more sense to compare which size each brand offers, the tire series, sidewall treatment, rim-width specification, and load figures, then match those details to the truck’s current wheel setup and the kind of appearance or road use you want.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Toyota Trucks 4Runner?
A period-style 1989 Toyota Trucks 4Runner can go in more than one direction. The 225/75R15 radial keeps the truck in a conventional metric size, while 31X10.50R15 creates a more aggressive late-1980s light truck look with a taller, wider flotation-style presentation.
The right choice depends on how the 4Runner is being restored or preserved. Owners aiming for a cleaner stock-style stance often begin with the metric radial, while trucks reflecting a more rugged accessory-era appearance may lean toward the larger light truck size after confirming wheel width and clearance.
How does tire construction affect the appearance of a restored 1989 Toyota Trucks 4Runner?
On the 1989 Toyota Trucks 4Runner, construction is straightforward because both associated primary sizes are radial tires. The visible difference comes less from bias-ply versus radial and more from the tire’s sizing format, sidewall styling, tread character, and overall width and height.
That means appearance choices are driven by presentation rather than construction conversion. A narrow or wide whitewall 225/75R15 creates a very different visual effect from a raised white letter 31X10.50R15, so restoration-minded buyers should decide whether the truck’s finish calls for a cleaner road look or a tougher truck stance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Toyota Trucks 4Runner?
Yes, modifications can change tire fitment on a 1989 Toyota Trucks 4Runner even when the wheel still measures 15 inches. Aftermarket wheels, different wheel widths, suspension lifts, lowering, or body and fender changes can all affect how a 225/75R15 or 31X10.50R15 tire sits and clears.
A truck that has been altered should be checked at full steering lock and through suspension movement before changing sizes. That is especially important when stepping into the wider 31X10.50R15 format, since a tire can share the same rim diameter yet still require different wheel and clearance conditions.
What should I inspect before driving a 1989 Toyota Trucks 4Runner on new tires?
Before driving a 1989 Toyota Trucks 4Runner on new tires, inspect the wheels for correct diameter and condition, verify lug hardware and mounting surfaces, and make sure the new tires are inflated properly. It also helps to check for any interference around the fenders, suspension, and steering components.
A collector or lightly used truck deserves the same attention after the tires are mounted. Recheck pressure after initial use, watch for uneven wear, and inspect the older suspension and steering parts that influence how the tire contacts the road, especially if the vehicle has sat for extended periods.
How should 225/75R15 or 31X10.50R15 tires on a collector 1989 Toyota Trucks 4Runner be maintained?
Collector-use tires on a 1989 Toyota Trucks 4Runner should be kept at appropriate inflation, inspected regularly for cracks, bulges, cuts, and uneven wear, and protected from long exposure to sunlight, heat, and ozone. Low-mileage trucks can age tires out long before they wear them out.
Routine maintenance also means paying attention to how the truck is stored and driven. Moving the vehicle periodically, checking for air loss, and inspecting tread and sidewalls before longer trips can help catch issues early, particularly on a 4Runner that alternates between storage, short local drives, and occasional highway use.
