1991 Mitsubishi Trucks Tire Fitment Guide

1991 Mitsubishi Trucks vehicles use four sizes: 195/75R14, 205/75R14, 225/75R15, and 235/75R15. The Mighty Max uses 195/75R14, 205/75R14, and 225/75R15, while the Montero uses 225/75R15 and 235/75R15. The 14-inch sizes mount on 14-inch wheels, and the 15-inch sizes mount on 15-inch wheels. Rim-width guidance appears across several of these sizes, including 5.00 to 7.00 inches and 5.50 to 7.50 inches for the 14-inch options, plus 6.00 to 8.50 inches depending on the 15-inch tire.

That means fitment starts with model identification and wheel diameter, not just the year and make. A Mighty Max owner may need either a 14-inch or 15-inch tire, while a Montero owner stays within the 15-inch group. Once the size is confirmed, the next comparison is usually sidewall style, since these are all radial constructions rather than a mix of bias-ply and radial formats.

On a 1991 Mitsubishi Trucks tire, 195/75R14 is a metric radial code. The 195 is the nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 14 is the wheel diameter in inches. On this year and make, that size belongs to the Mighty Max and mounts on a 14-inch wheel.

For a buyer, the important point is that 195/75R14 is not interchangeable with the 15-inch sizes without a wheel change. It is also narrower than the 205/75R14 option used on some Mighty Max applications, so the visual result and wheel compatibility can differ. If your truck already wears 14-inch wheels, checking the sidewall size on the tire and confirming wheel diameter before ordering is the safest starting point.

No, 1991 Mitsubishi Trucks models do not all use the same tire size. The Mighty Max spans three sizes across two wheel diameters, while the Montero uses two sizes and stays with 15-inch wheels. Only 225/75R15 is shared by both model lines, so there is no single size that covers every truck and SUV in the range.

That matters because a buyer who knows only the year and make can still end up with the wrong tire. A Mighty Max with 14-inch wheels needs a very different fitment path from a Montero on 15s. Checking the model badge, existing tire sidewall, and wheel diameter before comparing brands or whitewall styles will narrow the search quickly and avoid a mismatch.

1991 Mitsubishi Trucks tires come in several sidewall treatments depending on size. The 195/75R14, 205/75R14, and 225/75R15 sizes are available with narrow whitewall and wide whitewall styles, while 235/75R15 adds an RWL option alongside narrow and wide whitewalls. That gives owners of both the Mighty Max and Montero a broader appearance range than a plain blackwall-only fitment would.

The right choice depends on how you want the truck or SUV to present. A whitewall usually pushes the look toward a more classic, custom, or carefully restored appearance, while RWL reads more utility-oriented and better suits a period truck or SUV flavor. Sidewall style does not override size fitment, so choose the correct size first and then the look that matches your build.

1991 Mitsubishi Trucks tire coverage includes Coker Classic, Tornel, Maxxis, BFGoodrich, and American Classic, depending on size. The 195/75R14 is available from Coker Classic, Tornel, and Maxxis; 205/75R14 from American Classic, Coker Classic, and Maxxis; 225/75R15 from BFGoodrich, Coker Classic, and American Classic; and 235/75R15 from BFGoodrich, American Classic, Maxxis, and Coker Classic. All of these offerings are radial tires.

Brand choice usually comes down to the visual style you want and the exact size your truck or SUV requires. Some sizes lean more heavily toward classic whitewall presentation, while others include a more truck-like raised-white-letter look. Once the size is settled, comparing brand, sidewall treatment, and any published load or speed information is the best way to narrow the field.

In 225/75R15 for 1991 Mitsubishi Trucks, BFGoodrich Silvertown Radial appears with a 2.75-inch wide whitewall, a 1,874-pound load rating at 35 psi, a 15-inch rim diameter, and a 6.00-to-8.00-inch rim-width range. American Classic Radial in the same size uses a 1.6-inch narrow whitewall, the same 1,874-pound load rating at 35 psi, a 15-inch rim diameter, and the same 6.00-to-8.00-inch rim-width range. The main difference here is appearance rather than a dramatic spec split.

That makes the decision fairly straightforward if 225/75R15 is the correct fitment for your Mighty Max or Montero. Choose the BFGoodrich option if you want a fuller whitewall presentation, or the American Classic if you want a subtler white stripe on the same basic size. Checking your vehicle's intended visual style before choosing between the two is more useful than chasing a performance difference that the shared core dimensions do not suggest.

Rim-width guidance for 1991 Mitsubishi Trucks varies by tire size. In 195/75R14, products span 5.00 to 7.00 inches and 5.00 to 6.50 inches. In 205/75R14, the range runs from 5.00 to 7.00 inches and 5.50 to 7.50 inches. In 225/75R15, products cover 6.00 to 8.00 inches and 6.00 to 7.50 inches, while 235/75R15 extends from 6.0 to 7.0 inches on one product and up to 6.00 to 8.50 inches on others.

Those ranges show why wheel measurement matters before settling on a specific tire, even after the basic size is correct. A tire may be right in diameter but still better suited to a narrower or wider wheel within the accepted range. Measuring the wheel and matching it to the exact product's approved rim-width window is the best final check before moving ahead.

The available 1991 Mitsubishi Trucks sizes are offered as radial tires without tube-type markings such as TT. Their size markings appear in standard metric radial form, including examples like P195/75R14, 225/75R15, and 235/75R15 104S. That points toward modern tubeless-style construction rather than tube-type fitment for these applications.

Even so, the wheel itself still matters. An original wheel in poor condition, a damaged bead seat, or a restoration-specific setup can affect whether additional steps are appropriate. If you are reusing older wheels, inspect the rims carefully and confirm the exact tire-and-wheel pairing before installation rather than assuming every original wheel is automatically ready for modern tubeless service.

A 1991 Mitsubishi Trucks vehicle stores best on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources. Keeping the vehicle off bare dirt and away from standing moisture helps protect both the tires and the wheels. If the truck or SUV will sit for long periods, rolling it occasionally changes the contact patch and reduces the chance of flat spotting.

Collector vehicles often age their tires more from environment than from mileage. Tire covers, a clean concrete floor, and periodic pressure checks go a long way toward preserving sidewalls and tread shape. If the vehicle will remain parked for an extended season, some owners also use stands to reduce sustained load, but the tires should still be inspected carefully before going back into regular road use.

On a 1991 Mitsubishi Trucks vehicle, tire life is usually judged more by age and condition than by mileage alone. A good rule is to begin evaluating older collector-car and collector-truck tires closely around the five- to seven-year mark and to treat about ten years as a serious replacement point, even if tread remains. The DOT date code on the sidewall is the most useful starting point for establishing age.

That matters because a lightly used Mighty Max or Montero may still wear tires that look acceptable at a glance but have hardened rubber or developing sidewall cracks. Age, storage conditions, inflation history, and exposure to heat all influence service life. If there is any doubt, a close inspection by a tire professional familiar with older vehicles is worth more than relying on tread depth alone.

Tires on a 1991 Mitsubishi Trucks vehicle should be checked before every drive and inspected more thoroughly before any longer outing. Look for sidewall cracking, cuts, bulges, uneven wear, embedded debris, and pressure loss, and make sure the spare is still serviceable if the vehicle carries one. A quick walk-around catches problems early, especially on trucks and SUVs that may spend long stretches parked between drives.

A more detailed inspection every few months is a smart habit even for low-mileage use. Check valve stems, confirm inflation when the tires are cold, and pay attention to any vibration or pull that develops on the road. Early signs of aging or damage are easier to address in the garage than on the shoulder of the highway.

For a 1991 Mitsubishi Trucks Mighty Max, the period-correct starting point is radial construction, not bias-ply. The size itself depends on the truck, with 195/75R14, 205/75R14, and 225/75R15 all appearing within the model line. Whitewall radial offerings exist in those sizes today, but the exact original appearance can vary with wheel package, market, and trim details.

That means originality work on a Mighty Max should begin with the actual truck in front of you. Check the existing tire placard information if present, compare wheel diameter, and verify whether the truck's intended restoration theme calls for a cleaner factory-style look or a more personalized period style. For event-level authenticity, a Mitsubishi marque expert or original sales literature is still the best final reference.

Correct tire fitment absolutely matters when showing a 1991 Mitsubishi Trucks, even on a relatively modern collector vehicle. Judges and knowledgeable enthusiasts notice whether the size matches the model, whether the construction suits the era, and whether the sidewall style looks appropriate for the vehicle's intended presentation. A Montero wearing the wrong wheel diameter or a Mighty Max wearing a size outside its proper fitment family can stand out quickly.

The practical standard depends on the type of event. A local cruise-in may reward overall presentation, while stricter judged settings pay closer attention to size, profile, and whitewall or lettered sidewall appearance. If the goal is maximum authenticity, use the correct model-specific size first and then confirm the preferred sidewall treatment against period photos, brochures, or marque-club guidance.

In 235/75R15 for 1991 Mitsubishi Trucks, Coker Classic Star Series uses a 3.125-inch wide whitewall, carries a 2,271-pound load rating at 32 psi, fits a 15-inch rim, and suits 6-to-8-inch rim widths. Maxxis uses a .75-inch narrow whitewall, carries a 2,028-pound load rating at 35 psi, fits a 15-inch rim, and suits 6.00-to-8.00-inch rim widths. Both are radial tires, but they deliver a noticeably different visual effect.

That difference makes them useful for two distinct restoration directions on a Montero. The Coker Classic option pushes harder toward a strong vintage whitewall statement, while the Maxxis version keeps the same basic size with a subtler stripe. If appearance matters as much as fitment, compare the whitewall width to the rest of the vehicle's trim before choosing.

1991 Mitsubishi Trucks tire offerings here are all radial constructions, which is a familiar format for normal road use. The clearest speed information appears in 235/75R15, where one BFGoodrich option carries an S rating, meaning a 112 mph ceiling. That figure is far beyond ordinary highway speeds, and in real use the vehicle's condition, alignment, brakes, suspension, and load are usually more important than the tire's theoretical top-speed capability.

Safety still depends on the complete package rather than the sidewall code alone. A well-maintained Mighty Max or Montero on fresh, correctly inflated tires is very different from one riding on aged rubber or neglected wheels. Before sustained highway use, verify tire age, condition, balance, and pressure, and make sure the vehicle itself is mechanically ready for the trip.

Inflation pressure on 1991 Mitsubishi Trucks tires depends on the exact size and product. Examples include 195/75R14 options rated at 1,399 pounds at 35 psi and 1,521 pounds at 32 psi, 205/75R14 options rated at 1,532 pounds at 35 psi, 225/75R15 options rated at 1,874 pounds at 35 psi and 2,094 pounds at 32 psi, and 235/75R15 options rated at 1,985 pounds at 50 psi, 2,028 pounds at 35 psi, and 2,271 pounds at 32 psi.

Those figures are tire ratings, not a blanket inflation recommendation for every Mighty Max or Montero. Start with the vehicle's factory guidance for normal use, then compare it with the specific tire's construction and load information. Do not transfer one pressure figure from a different size or product, especially when moving between passenger-style whitewall radials and more truck-oriented alternatives.

Before a longer drive in a 1991 Mitsubishi Trucks vehicle, inspect all four tires and the spare for cracking, punctures, bulges, irregular wear, and proper cold inflation. Confirm that the size on the vehicle matches the wheel diameter, and look closely at valve stems and bead areas for age or damage. A longer trip is also the right time to verify lug torque, jack and spare readiness, and overall tread condition.

Tires are only one part of the preparation, but they are one of the easiest places to prevent trouble. A Mighty Max or Montero that has sat for weeks or months deserves an especially careful look before returning to sustained road use. Pair the tire inspection with a general check of brakes, fluids, steering, and suspension so the whole vehicle is as ready as the tires are.
