1989 Toyota Trucks Land Cruiser Tires

The 1989 Toyota Trucks Land Cruiser uses two primary tire sizes: 235/75R15 and 31X10.50R15. Both are radial tires for 15-inch rims, and the covered Base model can use either size depending on the wheel-and-tire setup on the truck.

That means the real fitment question is not just the model year and nameplate, but which combination is already on the vehicle. Checking the sidewall of the current tires, confirming wheel width, and looking for any suspension or wheel changes will help you choose the right replacement without assuming every Land Cruiser still wears the same setup.

The 1989 Toyota Trucks Land Cruiser uses a 15-inch rim with both of its primary tire sizes, 235/75R15 and 31X10.50R15. Even though the two sizes differ significantly in overall tire dimensions, they share the same rim diameter.

A shared 15-inch diameter does not mean every wheel is equally suitable for both sizes. Rim width still matters, especially when comparing the narrower 235/75R15 to the wider 31X10.50R15, so it is worth confirming the actual wheel width before changing sizes or replacing tires on a truck that may have been modified over the years.

The 1989 Toyota Trucks Land Cruiser has more than one tire size because it can be found with two different 15-inch radial setups: 235/75R15 and 31X10.50R15. Those sizes represent different tire profiles and overall dimensions rather than different rim diameters.

In practical terms, one truck may still carry a more stock-sized metric radial, while another may have a wider flotation-style all-terrain setup. The safest approach is to identify the actual size mounted now and confirm that the wheels, clearance, and intended use match the replacement tire you are considering.

Start with the size itself, since 235/75R15 is one of the primary radial fitments for the 1989 Toyota Trucks Land Cruiser. Then compare the tire’s intended character, sidewall style, rim-width specification, and load capacity, because available choices range from all-terrain raised white letter tires to narrow and wide whitewall radials.

That makes 235/75R15 a size with very different personalities depending on the product selected. A truck kept for utility or trail use may lean toward an all-terrain presentation, while a restoration-minded or street-driven Land Cruiser may call for a cleaner whitewall look, provided the wheel width and overall setup support the tire you choose.

Sidewall styles for 1989 Toyota Trucks Land Cruiser tires include raised white letter, narrow whitewall, and wide whitewall depending on the size and tire series. The broadest sidewall variety appears in 235/75R15, while 31X10.50R15 is represented by a raised white letter all-terrain option.

Sidewall style changes the truck’s appearance as much as the tread itself, especially on a visible 15-inch setup. Raised white letters suit a more rugged late-4x4 look, while narrow or wide whitewalls create a more customized or restoration-oriented presentation, so the right choice depends on how the Land Cruiser is being finished and driven.

Tires for the 1989 Toyota Trucks Land Cruiser are available from BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar in the applicable 15-inch sizes. Brand choice is most varied in 235/75R15, while 31X10.50R15 is represented here by a BFGoodrich all-terrain option.

Choosing among brands should come after confirming the correct size on the truck. Once size is settled, compare details that affect the result you want, such as sidewall treatment, tire series, rim-width compatibility, load figure, and whether the Land Cruiser is being used more for road miles, visual presentation, or a traditional all-terrain stance.

A period-style 1989 Toyota Trucks Land Cruiser usually starts with choosing the right primary size first, either 235/75R15 or 31X10.50R15, depending on the setup already on the truck. From there, the appearance can shift substantially between a raised white letter all-terrain look and several whitewall radial styles in 235/75R15.

The best visual match depends on whether the Land Cruiser is being kept closer to a late-1980s utility-truck character or interpreted in a more customized direction. When exact historical originality matters, it is worth checking model-specific photos, build literature, or marque-club guidance before settling on a sidewall treatment purely for appearance.

On the 1989 Toyota Trucks Land Cruiser, primary fitment is already radial, so the appearance difference comes less from bias-ply versus radial and more from size, tread style, and sidewall treatment. A 235/75R15 whitewall radial gives a very different visual impression than a 31X10.50R15 raised white letter all-terrain tire.

That means restoration appearance is shaped by the overall combination rather than construction alone. Tire diameter, section width, and sidewall styling all influence how the truck sits and reads visually, so matching the intended stance and era feel is just as important as selecting a tire that works with the Land Cruiser’s wheels and use.

Yes, modifications can affect tire fitment on a 1989 Toyota Trucks Land Cruiser even when the tire size itself is one of the correct primary options. Aftermarket wheels, different wheel widths, suspension lifts, ride-height changes, or body and steering adjustments can all change how a 235/75R15 or 31X10.50R15 tire sits on the truck.

That matters most when stepping up to the larger 31X10.50R15 size, since wheel width and clearance become more important. A quick check of wheel specs, steering sweep, fender space, and suspension condition can prevent rubbing or mismatch problems on a Land Cruiser that has been altered from its original setup over time.

Before driving a 1989 Toyota Trucks Land Cruiser on new tires, inspect the wheels for correct diameter and width, verify that the lug hardware seats properly, and confirm that the tires clear the suspension, steering components, and bodywork. It also helps to check inflation pressure, valve stems, and the condition of the spare if it remains part of the truck’s road-use plan.

A Land Cruiser that has sat for long periods deserves extra attention beyond the tires alone. Looking over wheel bearings, brakes, shocks, and steering components can reveal issues that make a fresh set of tires feel worse rather than better, especially on a heavier 4x4 that may be returning to regular road use.

Tires on a collector 1989 Toyota Trucks Land Cruiser should be checked regularly for pressure loss, uneven wear, sidewall cracking, cuts, bulges, and signs of long-term aging. Even a truck that sees limited mileage can develop tire problems simply from time, storage conditions, and long periods of inactivity.

Good maintenance also means keeping the Land Cruiser stored away from prolonged sunlight, excess heat, and ozone sources when possible. Rolling the vehicle occasionally, keeping inflation consistent, and inspecting the tread and sidewalls before each drive are smart habits, particularly if the truck alternates between storage, casual use, and occasional longer trips.
