The 1991 Mitsubishi Trucks Montero came from the era when sport utility vehicles were expected to handle real road trips, rough weather, and light trail use without giving up everyday comfort. Its upright proportions and truck-based character make tire choice especially important, because stance, sidewall look, and road manners all play into how the vehicle feels today. This Montero uses radial tire fitments in either 225/75R15 or 235/75R15, depending on the specific sub-model. Available choices range from traditional whitewall radials to raised white letter all-terrain styling. The right selection starts with confirming the exact trim, then balancing appearance, intended use, and wheel compatibility.
Which Tire Size Is Right for The 1991 Mitsubishi Trucks Montero
The 1991 Mitsubishi Trucks Montero uses two primary tire sizes, and the difference comes down to sub-model rather than construction or wheel diameter. Both fitments are radial tires for 15-inch rims, so the first step is identifying whether your Montero is a Base, LS, RS, or 3.0L-equipped model before comparing sidewall style, tire series, or overall tire character.
A 225/75R15 tire uses a 225-millimeter section width, a 75-series aspect ratio, radial construction, and a 15-inch rim diameter. On the 1991 Mitsubishi Trucks Montero, this size is the primary fitment for the Base model and keeps the selection firmly in modern radial territory. Available choices include BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar, with narrow and wide whitewall treatments across several series. This size makes the most sense when the vehicle still uses its correct Base-model wheel and you want to match fitment first, then choose the appearance that suits the truck.
A 235/75R15 tire follows the same metric radial format, but with a wider 235-millimeter section width and the same 75-series profile on a 15-inch rim. This size is used on the LS, RS, and Montero models equipped with the 3.0L engine, making it the larger of the two primary fitments. Product choices span BFGoodrich, American Classic, Coker Classic, Maxxis, Tornel, and Travelstar, with options that include raised white letters, narrow whitewalls, and wide whitewalls. It is the size to evaluate when your Montero is one of the higher-spec configurations and wheel setup should be confirmed before ordering.
Sub-model fitment matters on the 1991 Mitsubishi Trucks Montero because the covered versions do not all use the same tire size. The wheel diameter stays at 15 inches, but choosing the correct tire starts with confirming whether the truck is a Base, LS, RS, or 3.0L-equipped model.

1991 Mitsubishi Trucks Montero Base
The 1991 Mitsubishi Trucks Montero Base uses the smaller of the two primary radial fitments for this model line. That makes wheel and trim identification important before comparing whitewall styles, brands, or tire series intended for a more traditional road-going appearance.
The 1991 Mitsubishi Trucks Montero LS uses the larger primary radial size shared by several upper configurations. Tire selection here comes down to whether the goal is a more classic whitewall presentation or a more utility-focused look such as raised white letter styling.
The 1991 Mitsubishi Trucks Montero RS uses the same larger radial fitment found on other non-Base configurations. That gives the owner room to compare sidewall style, tire series, and rim-width compatibility while still staying within the correct primary size family.
The 1991 Mitsubishi Trucks Montero w/3.0L Eng. uses the larger of the two 15-inch radial fitments offered across this page. The key is confirming that the truck still has the wheel setup intended for that size before narrowing the choice by brand, sidewall treatment, or use case.
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.

Common 1991 Mitsubishi Trucks Montero tire questions usually come down to trim-specific sizing, 15-inch rim fitment, available radial styles, and how to choose between a classic-looking whitewall and a more utility-focused tire.
Tire Size & Fitment
What tire size fits a 1991 Mitsubishi Trucks Montero?
A 1991 Mitsubishi Trucks Montero uses either 225/75R15 or 235/75R15 radial tires, depending on the sub-model. The Base uses 225/75R15, while the LS, RS, and Montero models equipped with the 3.0L engine use 235/75R15.
That means the right size is tied to the exact version of the truck, not just the year and model name. Before choosing a tire, confirm the sub-model and make sure the vehicle still has its intended 15-inch wheel setup, especially if wheels or suspension have been changed over the years.
What size rim does a 1991 Mitsubishi Trucks Montero use?
Both primary tire sizes for the 1991 Mitsubishi Trucks Montero are built around a 15-inch rim diameter. Whether the truck uses 225/75R15 or 235/75R15, the rim diameter remains the same even though the section width and overall tire dimensions differ.
Rim diameter is only part of the fitment picture, so it helps to verify wheel width as well before selecting a tire. Several available products are intended for different rim-width ranges, and that matters when comparing classic whitewall radials against more utility-oriented options in the same 15-inch diameter.
Do all 1991 Mitsubishi Trucks Montero sub-models use the same tire size?
No. The 1991 Mitsubishi Trucks Montero Base uses 225/75R15, while the LS, RS, and w/3.0L Eng. versions use 235/75R15. All are radial tires on 15-inch rims, but the actual tire size is not shared across every covered sub-model.
This is why trim identification matters before ordering. A Montero that has changed hands several times may also have replacement wheels, so matching the tire to both the sub-model and the current wheel setup is the safest way to avoid choosing a size that does not suit the truck’s configuration.
Choosing the Right Tire
What should I consider when choosing a 1991 Mitsubishi Trucks Montero tire?
Start with the correct primary size for the truck’s sub-model: 225/75R15 for the Base or 235/75R15 for the LS, RS, and 3.0L-equipped versions. After that, compare sidewall treatment, tire series, rim-width compatibility, and the kind of look or use you want from the vehicle.
Some owners want a classic whitewall presentation that softens the Montero’s truck-based appearance, while others prefer a more rugged style. It also helps to compare load figures and wheel-width suitability among the available tires so the selection matches the vehicle’s setup rather than just the sidewall appearance.
What sidewall styles are available for 1991 Mitsubishi Trucks Montero tires?
Sidewall choices for the 1991 Mitsubishi Trucks Montero include narrow whitewall, wide whitewall, and raised white letter styling, depending on the tire size and product line. The 235/75R15 fitment also includes an all-terrain option with RWL lettering for a more utility-focused presentation.
That variety lets the tire play a larger role in the truck’s finished look. Whitewall radials tend to suit a more restoration-oriented or boulevard-style presentation, while raised white letters lean toward an SUV or light off-road character, so the best choice depends on how the Montero is driven and shown.
What brands offer tires for the 1991 Mitsubishi Trucks Montero?
Available brands for the 1991 Mitsubishi Trucks Montero include BFGoodrich, Coker Classic, American Classic, Maxxis, Travelstar, and Tornel, with availability varying by tire size. Some lines focus on whitewall radial styling, while others emphasize a more traditional SUV or all-terrain appearance.
Brand alone should not drive the decision. It makes more sense to compare the tire within the correct size, then look at sidewall style, series, rim-width range, and overall presentation. That approach keeps the focus on proper fitment and the character you want the truck to have on the road.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Mitsubishi Trucks Montero?
A period-style 1991 Mitsubishi Trucks Montero tire choice usually starts with the correct sub-model size, then moves to sidewall presentation. Whitewall radials in 225/75R15 or 235/75R15 can give the truck a more traditional, restoration-oriented look while keeping it within its proper radial fitment family.
The final decision depends on how original or personalized the vehicle is meant to appear. A narrow whitewall tends to be more restrained, while a wide whitewall makes a stronger styling statement, so owners aiming for historical accuracy should compare the finished look against period photos or marque-specific reference material.
How does tire construction affect the appearance of a restored 1991 Mitsubishi Trucks Montero?
On the 1991 Mitsubishi Trucks Montero, the primary fitments are radial tires, so the biggest appearance differences come from sidewall style and tread character rather than from choosing between bias-ply and radial construction. Whitewall radials can make the truck look more formal, while raised white letters create a more rugged period feel.
Because the Montero sits at the edge of modern SUV styling, tire appearance has a strong effect on the finished stance. Matching the correct size to the correct sub-model keeps proportions in line, and selecting the sidewall treatment carefully helps the truck look intentional instead of mismatched or overly generic.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Mitsubishi Trucks Montero?
Yes. A 1991 Mitsubishi Trucks Montero may have had aftermarket wheels, suspension changes, or other alterations over the years, and any of those can affect how a 225/75R15 or 235/75R15 tire sits on the vehicle. Wheel width and overall clearance matter just as much as the nominal size on the sidewall.
A truck that has been lifted, lowered, or fitted with different wheels should be measured before a new tire is chosen. Checking steering clearance, fender space, and the actual wheel dimensions helps avoid treating the original size recommendation as automatic when the current setup may no longer match factory-era hardware.
What should I inspect before driving a 1991 Mitsubishi Trucks Montero on new tires?
Before putting a 1991 Mitsubishi Trucks Montero into regular road use on new tires, inspect the wheels, valve stems, lug hardware, suspension condition, and alignment. It also makes sense to confirm that the selected tire matches the truck’s sub-model and wheel dimensions rather than assuming any 15-inch tire is suitable.
After installation, check inflation, look for any contact at full steering lock, and recheck for air loss once the vehicle has been driven. Older SUVs can hide worn steering or suspension parts, so a fresh set of tires should be paired with a general condition review rather than treated as the only item needing attention.
How should 225/75R15 and 235/75R15 tires on a collector 1991 Mitsubishi Trucks Montero be maintained?
Collector-use 225/75R15 and 235/75R15 tires should be maintained with regular pressure checks, visual inspection, and clean storage habits. Low-mileage trucks are not exempt from tire aging, so sidewall cracking, bulges, cuts, flat spotting, and slow air loss deserve attention even when tread wear is minimal.
A Montero that spends long periods parked benefits from being stored away from prolonged sunlight, moisture, and ozone sources. Moving the vehicle occasionally, keeping inflation consistent, and inspecting the tires before longer drives helps preserve both appearance and roadworthiness, especially on vehicles that are used more for enjoyment than daily transportation.
