1989 Mitsubishi Trucks Montero Tires

A 1989 Mitsubishi Trucks Montero uses either 225/75R15 or 235/75R15, depending on the exact sub-model. Base and SP models use 225/75R15, while LS, Sport, w/3.0L Eng., and SP w/3.0L Eng. use 235/75R15. Both are radial tire sizes built for 15-inch rims.

The important step is matching the tire size to the specific Montero configuration instead of choosing by appearance alone. A 15-inch wheel is common across both sizes, but the section width and overall tire dimensions are different, so the sub-model and current wheel setup should be confirmed before making a final tire choice.

The 1989 Mitsubishi Trucks Montero uses a 15-inch rim with both of its primary tire sizes, 225/75R15 and 235/75R15. That shared rim diameter simplifies the first level of fitment, since both sizes are built around the same 15-inch wheel diameter even though they are not the same tire.

Rim diameter is only one part of the fitment picture. Wheel width still matters, especially when comparing different radial products within the same size, and many Monteros have seen wheel changes over the years. Measuring the actual wheel on the vehicle helps prevent choosing a tire whose recommended wheel range does not match your setup.

The 1989 Mitsubishi Trucks Montero has more than one tire size because fitment varies by sub-model. Some versions use 225/75R15, while others use 235/75R15, even though all of them use radial construction on 15-inch rims. The difference is tied to the specific Montero configuration rather than a universal one-size-fits-all setup.

That means the right starting point is the exact trim or engine designation on the vehicle. Once the sub-model is confirmed, the remaining decision is easier and shifts toward tire style, series, and wheel compatibility. This matters especially on older SUVs, where replacement wheels or previous tire changes may no longer match the original-size pattern.

Start with the correct primary size for the exact 1989 Mitsubishi Trucks Montero sub-model, since some use 225/75R15 and others use 235/75R15. After size, compare tire construction, sidewall style, brand, tire series, load capacity, and the wheel-width range that each product is built to work with.

The best choice depends on how the Montero is actually used and how you want it to look. A whitewall radial gives a more traditional presentation, while the raised white letter all-terrain option in 235/75R15 leans more toward truck character. Wheel condition, suspension height, and the vehicle's current stance are all worth checking before deciding.

Sidewall choices for the 1989 Mitsubishi Trucks Montero include narrow whitewall, wide whitewall, and raised white letter styles, depending on tire size and product line. The 225/75R15 options stay focused on whitewall presentations, while 235/75R15 includes both whitewall radials and a raised white letter all-terrain choice.

That makes sidewall style one of the main visual decisions once the correct size is confirmed. Whitewalls can suit a more restoration-oriented or period-style Montero, while raised white letters create a more utility-driven look. Appearance should still be balanced against the product's wheel-width requirements and the way the truck is driven and displayed.

Available brands for the 1989 Mitsubishi Trucks Montero include BFGoodrich, Coker Classic, American Classic, Maxxis, Tornel, and Travelstar. Brand availability depends on whether your Montero uses 225/75R15 or 235/75R15, and the mix also changes by tire series and sidewall style within each size.

Brand alone should not be the only filter. It helps to compare the full tire package, including size, sidewall treatment, series character, rim-width range, and load figure at the stated pressure. On a vehicle like the Montero, the right tire often comes down to matching the visual style and wheel setup just as carefully as the name on the sidewall.

A period-style 1989 Mitsubishi Trucks Montero usually starts with the correct primary size for the specific sub-model, then moves to a radial with a traditional sidewall treatment. Whitewall options in both 225/75R15 and 235/75R15 create a more vintage presentation than a modern truck tire, while still keeping radial construction.

The appearance that feels right depends on the truck's role and finish. A cleaner, more restored Montero may suit narrow or wide whitewalls, while a more trail-oriented look may point elsewhere. Exact originality questions should be checked against marque-specific references or period photos, since correct size does not automatically define exact original appearance.

On the 1989 Mitsubishi Trucks Montero, the primary fitments are already radial, so the appearance difference comes less from bias-ply versus radial construction and more from sidewall style and tire series. Narrow whitewalls, wide whitewalls, and raised white letters each change the truck's visual character in a noticeable way.

That matters on a restored SUV because tires strongly influence stance and period impression. A whitewall radial can give the Montero a more refined late-1980s look, while an RWL all-terrain reads more rugged and truck-oriented. The most convincing result usually comes from matching the tire's visual style to the vehicle's trim, finish, and intended use.

Yes, modifications can affect tire fitment on a 1989 Mitsubishi Trucks Montero even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, suspension lifts or lowering, and body or fender alterations can all change how a 225/75R15 or 235/75R15 tire sits on the vehicle.

That is why the actual wheel and vehicle setup should be checked before settling on a replacement tire. Diameter alone does not tell the whole story, and an older SUV may no longer be running its original wheels. Steering clearance, suspension travel, and visible tire-to-body spacing are all worth reviewing before road use.

Before driving a 1989 Mitsubishi Trucks Montero on new tires, inspect the wheels for damage, confirm the tire size matches the sub-model, and make sure the wheel width falls within the tire's usable range. It also helps to check valve stems, lug hardware, and overall mounting condition before putting miles on the vehicle.

A short inspection drive is a smart next step. Watch for rubbing during turns, listen for contact over bumps, and confirm that inflation is set appropriately for the tire being used. On an older Montero, suspension wear or alignment issues can show up quickly after a tire change, so early rechecking helps catch problems before they grow.

Tires on a collector 1989 Mitsubishi Trucks Montero should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and checked for air loss during storage. Even when tread looks good, low-use collector vehicles can age their tires through time, temperature swings, and long stationary periods.

Storage conditions make a real difference on a vintage SUV. Keeping the Montero away from prolonged sunlight, excess moisture, and ozone sources helps preserve the rubber, while moving the vehicle occasionally can reduce flat spotting from sitting too long. A careful visual inspection before each season or longer drive is a sensible habit.
