1991 Mitsubishi Tire Fitment Guide

1991 Mitsubishi vehicles use eight sizes across five models: 225/55R16 and 245/45R17 for the 3000GT; 185/70R14 and 205/55R16 for the Eclipse; 185/70R14 and 195/60R15 for the Galant; 155/80R13, 175/70R13, and 195/60R14 for the Mirage; and 155/80R13 plus 175/70R13 for the Precis. Rim diameters span 13, 14, 15, 16, and 17 inches, so the year and make alone are not enough to choose a tire correctly.

That means fitment starts with identifying the model and then confirming the wheel diameter already on the car. Rim width guidance also changes by size, with examples including 4.00 to 5.50 inches for some 155/80R13 applications, 5.00 to 6.50 inches for 185/70R14, 5.50 to 7.00 inches for 195/60R15, 5.5 to 7.5 inches for 205/55R16, 6.0 to 8.0 inches for 225/55R16, and 7.5 to 9.0 inches for 245/45R17. Checking the wheel before ordering helps avoid a mismatch even within the same model family.

On a 1991 Mitsubishi, 225/55R16 is a metric radial size. The 225 is the nominal section width in millimeters, 55 is the aspect ratio, R means radial construction, and 16 is the wheel diameter in inches. Within the 1991 Mitsubishi range, that size belongs to the 3000GT and uses 16-inch wheels.

Understanding the code matters because a 225/55R16 is not interchangeable with a 245/45R17 just because both belong to a 3000GT family. The section width, sidewall profile, and wheel diameter all change, and that affects what tire will physically mount and how the car sits. If your 3000GT wears 16-inch wheels, 225/55R16 is the fitment to verify against the actual wheel and any existing placard or owner documentation.

No. 1991 Mitsubishi models do not share one universal tire size. The compact Precis and some Mirage applications use 13-inch sizes, the Eclipse and Galant use 14-, 15-, or 16-inch fitments depending on model, and the 3000GT moves into 16- and 17-inch performance sizes. Only a few sizes are shared across models, such as 185/70R14 between the Eclipse and Galant, and 155/80R13 or 175/70R13 between the Mirage and Precis.

That spread reflects how broad Mitsubishi's lineup had become by 1991, from economy transportation to a flagship sports coupe. For a buyer, the practical takeaway is simple: start with the exact model name before you start comparing brands or sidewall styles. If the car has had wheel changes over the years, confirm the current wheel diameter as well, because some models had more than one valid tire size within the same model year.

Sidewall style varies widely across 1991 Mitsubishi sizes. Performance-oriented sizes such as 225/55R16, 245/45R17, 205/55R16, 175/70R13, and 195/60R14 are blackwall-only here, while 185/70R14 adds a wide whitewall choice, 195/60R15 expands to blackwall, wide whitewall, redline, and raised white letter, and 155/80R13 offers narrow and wide whitewall styles. That means the look of the tire can change substantially even when the size stays correct.

For a 1991 Mitsubishi 3000GT or sport-focused Eclipse, blackwalls usually align most naturally with the period's factory performance appearance. On a Galant, Mirage, or Precis, a whitewall or redline can create a more customized or nostalgic presentation even though that is more a style decision than a fitment one. The right choice comes down to whether you want an OEM-flavored look, a period-accessory feel, or a cleaner modern appearance.

1991 Mitsubishi tire fitments are covered by BFGoodrich, M&H Racemaster, Nitto, Avon, Dunlop, Michelin, Travelstar, Maxxis, and Tornel. Brand coverage changes by size: BFGoodrich handles 225/55R16, 205/55R16, and much of 195/60R15; M&H Racemaster, BFGoodrich, and Nitto appear in 245/45R17; Avon, Dunlop, Michelin, and BFGoodrich appear in 185/70R14; and the 13-inch compact sizes spread across Travelstar, BFGoodrich, Maxxis, Tornel, and Avon.

That mix means brand choice is driven first by size, then by the kind of look or use you want from the car. Some sizes focus almost entirely on blackwall sport radials, while others give you whitewall, redline, or raised white letter options. If you are comparing brands for a 1991 Mitsubishi, narrow the decision by confirming the exact size first, then compare speed rating, sidewall style, and rim-width suitability within that size.

For a 1991 Mitsubishi Galant in 195/60R15, BFGoodrich Radial T/A and Michelin Primacy 3 serve different purposes even though they share the same basic fitment. The BFGoodrich Radial T/A uses an RWL sidewall and carries an S speed rating with a 112 mph ceiling, while the Michelin Primacy 3 is a blackwall tire with a V speed rating and a 149 mph ceiling. Both fit 15-inch wheels, and both work within roughly the same 5.5- to 7-inch rim-width range.

The practical difference is appearance and character. A Radial T/A leans into a more period-style enthusiast look because the raised white letters are part of the tire's visual appeal, while the Michelin blackwall presents a cleaner, more understated finish. If your Galant is being kept close to a subtle factory-style appearance, the Michelin approach may fit that goal better; if you want a more expressive sidewall, the BFGoodrich stands apart immediately.

Rim width depends on the size used on the 1991 Mitsubishi model. 155/80R13 products span examples from 4.00 to 5.50 inches, 175/70R13 uses 4.5 to 6.0 inches, 185/70R14 runs from about 4.5 to 6.5 inches, 195/60R15 uses 5.5 to 7.0 inches, 205/55R16 uses 5.5 to 7.5 inches, 225/55R16 uses 6.0 to 8.0 inches, and 245/45R17 uses either an 8-inch wheel or a broader range around 7.5 to 9.0 inches depending on the tire.

Those ranges are important because two tires with the same size code can still differ slightly in their preferred wheel width. Before choosing a tire for a 1991 Mitsubishi, measure or confirm the wheel you actually have on the car, especially if it may have been changed from original. Matching the tire to the proper wheel width helps preserve the intended section shape and avoids forcing a tire onto a rim that is too narrow or too wide.

Tube use varies by size and by product within the 1991 Mitsubishi range. Some tires are clearly marked TL, such as the Michelin XAS in 185/70R14, the Michelin SX MXX3 N2 in 205/55R16, the Michelin Primacy 3 in 195/60R15, and the Michelin MXV3-A in 195/60R14, which identifies them as tubeless. Many other products do not carry a tube marking in the size description, so the correct setup depends on the specific tire and wheel combination rather than the year and make alone.

The practical step is to confirm both the tire marking and the wheel type before final installation. A tubeless tire still depends on a wheel that is suitable for tubeless service and in good condition, while older or damaged wheels may call for more caution. If you are working with original wheels on a 1991 Mitsubishi that has seen decades of use, inspect bead seats and valve-stem areas carefully before deciding how the tire should be set up.

No, original 1991 Mitsubishi wheels cannot be assumed to work with every size across the full model range because wheel diameters differ substantially. The lineup uses 13-, 14-, 15-, 16-, and 17-inch fitments, and a tire must match the wheel diameter exactly. A 155/80R13 cannot mount on a 14-inch wheel, just as a 245/45R17 cannot mount on a 16-inch wheel.

Even within the same model family, more than one wheel diameter may have been used, so it is wise to inspect the wheel itself rather than rely on memory or appearance. Once diameter is confirmed, check the tire's acceptable rim-width range against the wheel you have. That matters particularly on cars like the Mirage, Eclipse, and 3000GT, where more than one valid size existed and the wheel package changes the correct tire choice.

A 1991 Mitsubishi stores best in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age rubber. Keep the tires clean, maintain inflation, and move the car occasionally so one part of the tread does not carry the load for months at a time. Because every size here is radial, long static periods are generally easier on the tread shape than with older bias-ply designs, but flat-spotting and surface cracking can still develop with neglect.

Collectors who park a 1991 Mitsubishi for the season often gain extra protection by rolling the car periodically or using stands in a way that does not stress the suspension. Moisture control matters just as much as sunlight because damp floors and repeated temperature swings accelerate aging. If the car is stored with decorative whitewall or redline tires, keep those sidewalls clean and free from harsh petroleum-based dressings that can stain or dry the rubber.

Tires on a 1991 Mitsubishi should be judged more by age and condition than by mileage, especially on collector-driven cars. A sensible rule is to evaluate them closely once they reach about five to seven years of age and to treat around ten years as a serious replacement point even if tread remains. The DOT date code on the sidewall tells you when the tire was built, which is often more useful than asking how many miles the car has covered.

That matters because many enthusiast cars spend long stretches parked, and rubber can age out before it wears out. A 3000GT driven only on sunny weekends and a Precis used occasionally around town can both develop age-related issues despite low mileage. If the sidewalls are hardening, checking, or losing flexibility, the tire's calendar age is telling you more than the tread depth is.

Tires on a 1991 Mitsubishi should be inspected before every drive and given a more thorough check before any longer trip. Look for cracking, bulges, cuts, irregular tread wear, punctures, and any sign that the tire is losing pressure between outings. On tubeless products, pay close attention to valve stems and bead sealing, and on any car with older wheels, inspect the wheel condition as part of the same routine.

A short local drive can hide problems that become obvious only after heat builds at sustained speed. That is especially true on hobby cars that sit for weeks and then go straight onto the road. Regular inspection also helps you catch alignment or suspension issues early, since unusual shoulder wear or feathering often appears in the tire before the car gives a more obvious warning.

A 1991 Mitsubishi 3000GT originally belongs in the radial era, and the 3000GT fitments here are 225/55R16 and 245/45R17. Those sizes reflect the model's performance-oriented character and its place as Mitsubishi's flagship sports coupe in the early 1990s. Original-equipment branding can vary by market and specification, so the most reliable authenticity check is the car's own placard, owner's literature, and marque-specific references rather than assuming one tire brand was universal.

For restoration purposes, construction type is straightforward because a 1991 3000GT should be on radials, not bias-ply tires. The finer authenticity decision is usually the exact size, wheel diameter, and sidewall appearance appropriate to the car's version and market. If you are preparing a 3000GT for judged display, compare the current wheels and tire markings against period materials and consult a Mitsubishi enthusiast group for trim-specific confirmation.

Yes, correct tire fitment matters on a 1991 Mitsubishi if the car is being judged for originality or presented as a careful restoration. Judges and knowledgeable enthusiasts notice whether the tire size matches the model, whether the wheel diameter is correct, and whether the sidewall style suits the era and character of the car. A 3000GT wearing the wrong wheel diameter or a compact Mirage carrying a size meant for another model would stand out quickly.

The standard is often stricter for presentation than for casual driving. A blackwall usually looks most natural on sportier 1991 Mitsubishi applications, while whitewalls, redlines, or raised white letters create a more customized or accessory-style appearance on some sizes. If a particular event has detailed authenticity rules, verify them through the hosting club or marque specialists before finalizing the tire choice.

For a 1991 Mitsubishi 3000GT, BFGoodrich offers both g-Force Sport COMP-2 and g-Force COMP-2 A/S in 225/55R16, and both carry a 95W marking with a 168 mph ceiling where that speed symbol appears. They share the same 16-inch rim diameter, the same 6.0- to 8.0-inch rim-width range, the same blackwall appearance, and essentially the same product weight at 26 pounds. The main difference is the series itself rather than a visible change in fitment dimensions.

For the buyer, that means the decision is less about whether the tire will mount correctly and more about which BFGoodrich line better suits the way the car is used. Since both fit the same wheel range and carry the same W-speed capability in this size, comparing the series is a matter of tire family preference rather than sizing. Either way, the tire still needs to match a 16-inch 3000GT wheel, not the separate 17-inch fitment.

Yes, 1991 Mitsubishi tires can be suitable for highway driving when the tire's condition, speed rating, and load capability match the way the car is actually used. Several sizes carry modern speed symbols, including S at 112 mph, T at 118 mph, H at 130 mph, V at 149 mph, W at 168 mph, and Y at 186-plus mph depending on size and product. Those limits are well above normal U.S. highway speeds, and on many older enthusiast cars the vehicle's brakes, suspension condition, and overall mechanical state matter as much as the tire's speed capability.

The key is to evaluate the exact tire on the exact car rather than treating all 1991 Mitsubishi fitments as equal. A compact Precis on a 13-inch T- or H-rated tire and a 3000GT on a W-rated 17-inch performance tire have very different mission profiles. Before a sustained highway run, confirm pressure, inspect for age cracking and damage, and make sure the car itself is roadworthy enough to use the tire safely at speed.

Inflation pressure on a 1991 Mitsubishi depends on the exact tire size, the product itself, and the vehicle's original recommendation. Several tires here include maximum load and pressure references, such as 1521 pounds at 51 psi for some 225/55R16 and 245/45R17 applications, 1201 pounds at 35 psi for one 185/70R14, 1190 pounds at 35 psi for one 195/60R15, and 959 pounds at 35 psi for some 155/80R13 products. Those figures are tire capacity limits, not a blanket instruction to run every Mitsubishi at that pressure.

The best approach is to start with the factory pressure recommendation for the specific 1991 Mitsubishi model and size, then confirm that the chosen tire is appropriate for that operating pressure. Avoid transferring a pressure from one size to another just because both belong to a 1991 Mitsubishi. If the car has been fitted with a different wheel or a reproduction tire with a different construction emphasis, consult the tire maker's guidance alongside the vehicle's original literature.

Before taking a 1991 Mitsubishi on a longer drive, inspect every tire for cracking, cuts, bulges, punctures, uneven wear, and proper cold inflation pressure. Check the valve stems, confirm that the spare is usable, and make sure the tire size on the car matches the wheel diameter at each corner. If the car has sat for long periods, look for flat-spotting and verify that each tire is holding pressure evenly.

Tires are only one part of the preparation, but they are the only part actually touching the road. A longer trip in a 3000GT, Eclipse, Galant, Mirage, or Precis also deserves a quick look at brakes, steering, suspension, and fluid levels because age-related issues often show up when a hobby car is finally driven at sustained speed. Catching a weak tire or valve stem in the garage is much better than discovering it on the shoulder.
