1991 Acura Tire Fitment Guide

1991 Acura vehicles use four sizes across three model lines. The Integra uses 195/60R14, the Legend uses 205/60R15, and the NSX uses a staggered combination of 205/50R15 front and 225/50R16 rear. Those sizes do not interchange across the full Acura range for the year, and the rim diameters involved are 14, 15, and 16 inches depending on model and axle position.

That means the first step is identifying the exact model, and in the case of the NSX, confirming whether you are choosing a front or rear tire. If you start with year and make alone, it is easy to end up with the wrong diameter or the wrong staggered position. Treat 1991 Acura fitment as model-specific rather than brand-wide.

On a 1991 Acura, 195/60R14 is a metric radial size. The 195 is the nominal section width in millimeters, 60 is the aspect ratio, R means radial construction, and 14 is the wheel diameter in inches. For 1991 Acura applications, that size belongs to the Integra.

Understanding the code helps you avoid confusing it with the 15-inch and 16-inch Acura sizes used elsewhere in the lineup. Even though the width number may seem close to other Acura fitments, the wheel diameter and sidewall profile are different. If your Integra still has its original wheel diameter, 195/60R14 is the size family you should be checking first.

No, 1991 Acura models do not use the same tire size. The Integra uses 195/60R14, the Legend uses 205/60R15, and the NSX uses 205/50R15 in front with 225/50R16 in the rear. Acura's lineup that year covered compact sport, executive luxury, and exotic performance roles, so tire dimensions changed with the model's purpose.

That variation matters because wheel diameter, sidewall height, and front-to-rear balance all affect how the car sits and drives. It also means a buyer should verify the exact model before comparing brands or sidewall styles. For an NSX owner, axle position matters just as much as model identification because the car was built around a staggered setup.

1991 Acura tire choices include more than one sidewall look, depending on size. The Integra's 195/60R14 appears in blackwall form, the NSX rear size 225/50R16 is also available in blackwall, and the Legend's 205/60R15 opens up the broadest visual range with blackwall, wide whitewall, and raised white letter options. All of these are radial constructions.

For a stock-looking Integra or NSX, blackwall is the most natural visual match to Acura's early-1990s design language. The Legend can stay similarly restrained with a blackwall, while whitewall or RWL versions take the car in a more personalized direction. If originality matters, choose the sidewall style that best suits the way your particular Acura is being restored or presented.

Michelin, American Classic, Coker Classic, and BFGoodrich all have coverage within the 1991 Acura range. Michelin appears in 195/60R14, 205/60R15, and 225/50R16 applications. BFGoodrich covers 205/60R15 and 225/50R16, while American Classic and Coker Classic appear in the 205/60R15 size used on the Legend.

Brand choice depends largely on which Acura model you own and the kind of presentation you want. The Legend's 205/60R15 size gives the widest mix of visual styles and brand personalities, while the NSX rear size stays focused on blackwall performance-oriented radial options. Once the correct size is pinned down, brand selection becomes much easier and more meaningful.

For the 1991 Acura Legend in 205/60R15, BFGoodrich Radial T/A and Michelin Primacy 3 differ in sidewall style, speed rating, and some fitment details. The BFGoodrich uses an RWL sidewall, carries an S rating to 112 mph, fits 5.50- to 7.50-inch rims, and shows a 1,301-pound maximum load at 35 psi. The Michelin Primacy 3 uses a blackwall sidewall, carries a W rating to 168 mph, and fits 5.5- to 7.5-inch rims.

That makes the choice less about basic fit and more about appearance and tire character. A buyer who wants a sportier period accessory look may lean toward the RWL BFGoodrich, while a cleaner modern luxury appearance points toward the blackwall Michelin. The higher marked speed rating on the Michelin does not change the need to drive within the capabilities of the Legend itself.

Rim width guidance for 1991 Acura tires depends on the size. In 205/60R15 for the Legend, examples are specified for 5.5- to 7.5-inch rims. In 225/50R16 for the NSX rear, the available fitment range is 6.0- to 8.0-inch rims. A 14-inch diameter is confirmed for 195/60R14 and a 15-inch diameter is confirmed for 205/50R15, but width guidance is not expanded here.

The practical takeaway is to verify both wheel diameter and wheel width before choosing a tire, especially if your Acura is wearing replacement or aftermarket wheels. Diameter mismatch is an immediate stop, but width also influences how the tire seats and presents on the rim. On an NSX, keep front and rear wheel specifications separate because the car uses different tire sizes on each axle.

Most 1991 Acura tire applications here are radial passenger-car fitments that appear in tubeless form, but tube status is not uniform across every product marking. The 195/60R14 Michelin example is marked TL, and the 225/50R16 Michelin example is also marked TL. In 205/60R15 for the Legend, some products show no tube designation in the size marking, so tube status varies by product rather than staying fully consistent across the size.

That means the safest approach is to check the exact sidewall marking and the wheel type you plan to use before final installation. If the car still wears its factory-style one-piece tubeless wheel, many modern radial products will align with that setup, but the individual tire marking remains the final word. Valve stem condition should also be part of the decision.

A 1991 Acura should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, furnaces, and other ozone-producing equipment. Keep the tires clean, maintain inflation, and move the car periodically so the same contact patch is not carrying the full load for months at a time. Radials generally tolerate storage better than old bias-ply designs, but they still age from time, heat, and environment.

If the car will sit for an extended season, placing it on stands or at least rolling it occasionally helps reduce flat spotting and stress on one part of the casing. Collector cars such as a 1991 Acura NSX, Legend, or Integra often accumulate little mileage, so storage conditions become just as important as road use. Good storage habits protect both ride quality and appearance.

On a 1991 Acura, tire life should be judged more by age than mileage, especially on collector-owned cars that may be driven only occasionally. A sound rule is to begin evaluating tires closely once they are around five to seven years old and to treat the ten-year mark as a serious replacement threshold regardless of remaining tread. The DOT date code on the sidewall is the best way to determine actual age.

That matters because a lightly used tire can still harden, crack, or lose structural resilience long before the tread looks worn out. A garage-kept NSX that sees weekend use and a daily-driven Legend may reach replacement for different reasons, but age remains central for both. If the date code and physical condition point to an older tire, replacement deserves priority over tread depth alone.

Tires on a 1991 Acura should be checked before every drive and inspected more thoroughly before any longer trip. Look for sidewall cracking, punctures, unusual tread wear, cuts, bulges, vibration complaints, and pressure loss. If your chosen product has a tubeless marking, inspect valve stems and bead areas as well, since air loss is often tied to those points rather than the tread itself.

Frequent inspections matter because these cars are old enough that a tire issue may appear after long storage, infrequent use, or age-related rubber hardening. On an NSX, compare front and rear tires separately since they are different sizes and may age or wear differently. Catching a problem in the garage is far preferable to discovering it on the road.

A 1991 Acura NSX would have been built around a radial tire package, and the correct fitment pattern for the model is a staggered setup with 205/50R15 in front and 225/50R16 in the rear. That aligns with the NSX's role as a modern high-performance exotic at the start of the 1990s, when low-profile radial construction was already standard practice for this kind of car.

For a restoration, the most important points are preserving the front-and-rear size relationship, keeping the proper wheel diameters, and choosing a sidewall appearance that suits the period. If you are chasing exact market or delivery-spec details, consult Acura marque specialists or NSX clubs, especially when judging standards or regional variations matter. The size layout itself is the foundation.

Yes, correct tire fitment matters when showing a 1991 Acura because judges and knowledgeable enthusiasts notice size, construction type, sidewall style, and overall stance. A Legend wearing an out-of-character custom sidewall treatment, or an NSX missing its proper staggered front-and-rear sizing, can look immediately wrong even before anyone studies the rest of the car. Tire profile has a strong effect on proportions.

The level of scrutiny depends on the event. A local cars-and-coffee crowd may care mostly that the car looks right and sits correctly, while marque judging can be more exacting about visual authenticity. If concours accuracy is your goal, use the model-correct size first and then verify sidewall expectations with Acura clubs or event rulebooks before making a final choice.

For the 1991 Acura Legend in 205/60R15, American Classic Radial and Coker Classic Star Series are both radial wide whitewall options, but they differ in some published load and fitment details. The American Classic shows a 1,301-pound maximum load at 35 psi and fits 5.50- to 7.50-inch rims. The Coker Classic Star Series shows a 1,521-pound maximum load at 32 psi, and both carry the same overall size code.

That makes them similar in overall concept but not identical in specification. A buyer comparing the two should think about the exact look of the whitewall, the intended use of the Legend, and the wheel dimensions already on the car. For a restoration or a custom-oriented presentation, those visual and setup differences can matter just as much as the basic 205/60R15 size match.

1991 Acura tire options here are all radial constructions, and where speed ratings appear they span S, V, W, and Y markings depending on size and product. That means some carry a stated ceiling of 112 mph, while others are marked to 130, 168, or 186+ mph. For normal highway use, those ratings are generally well above legal cruising speeds, especially on the Integra and Legend.

Safety on the road still depends on more than the speed symbol. Tire age, inflation, wheel condition, alignment, suspension health, and the car's own braking and chassis condition are just as important on a 1991 Acura. On an NSX in particular, maintaining the proper staggered setup is part of preserving the handling balance the car was engineered to have.

Inflation pressure for a 1991 Acura should start with the factory vehicle recommendation, then be checked against the tire manufacturer's sidewall and service information for the exact product you choose. Some available products include load-and-pressure references, such as 205/60R15 examples showing 1,301 pounds at 35 psi and 1,521 pounds at 32 psi, plus a 225/50R16 example showing 1,389 at 51. Those figures are tire capacities, not universal Acura settings.

Do not transfer one pressure number from a Legend tire to an NSX tire or from one brand to another simply because the dimensions look similar. Acura's original recommendation is tied to the vehicle's weight distribution, suspension tuning, and intended ride quality. Use the car's placard or manual as the baseline, then confirm that your exact tire supports that operating range.

Before taking a 1991 Acura on a longer drive, inspect all tires for cracking, tread damage, punctures, bulges, and signs of air loss, and verify pressures when the tires are cold. Check valve stems, confirm the spare is serviceable, and on an NSX make sure the front and rear sizes are correctly positioned. Uneven wear can also point to alignment or suspension issues that deserve attention before distance driving.

A pre-trip tire inspection should be part of a wider mechanical check on a car of this age. Brake condition, fluids, belts, hoses, cooling system health, and battery condition all matter alongside the tires. Even a well-kept 1991 Acura can develop age-related issues that only show up after long storage or infrequent use, so a deliberate once-over is time well spent.
