1991 Avanti Tire Fitment Guide

1991 Avanti vehicles use one tire size: 215/60R15, and it applies to the 1991 Avanti II. That size mounts on a 15-inch wheel, and the available products for it cover rim-width ranges from 5.50 to 7.50 inches depending on the tire. Some versions are intended for 5.50 to 7.50-inch rims, while others call for 6.00 to 7.50-inch rims, so the exact tire matters even within the same size code.

That makes 1991 Avanti fitment simpler than many vintage applications, because you are not sorting through multiple diameters or model-specific tire families. The key step is confirming the actual wheel width on your Avanti II and then choosing the sidewall style and speed rating that fit your goals. If the car has aftermarket wheels, verify the wheel dimensions before settling on a specific product.

On a 1991 Avanti, 215/60R15 is a metric radial size. The 215 is the nominal section width in millimeters, the 60 is the aspect ratio, meaning the sidewall height is 60 percent of the section width, the R identifies radial construction, and the 15 is the wheel diameter in inches. It is a modern sizing format compared with older numeric or alphanumeric classic-car sizes.

For a 1991 Avanti II owner, that code tells you the car uses a lower-profile radial on a 15-inch wheel rather than an older tall-sidewall bias-ply fitment. It also explains why you will see different cosmetic treatments in the same basic size, such as blackwall, redline, whitewall, or raised white letter. Once the size is confirmed, the remaining decision is about appearance, load capacity, and speed rating.

Yes. The 1991 Avanti range covered here centers on the Avanti II, and it uses 215/60R15. There is no split between multiple Avanti model cores with different tire diameters or alternate factory size families in this year-and-make grouping, so the fitment path stays consistent across the page.

That consistency means most buyers do not need to decode several model-specific combinations before narrowing the tire search. Instead, the important distinction is which 215/60R15 product best suits the car’s character, whether that means a blackwall performance-oriented look or a more traditional whitewall or redline presentation. It is still wise to compare the wheel on the car against the tire’s approved rim-width range.

1991 Avanti tires in 215/60R15 are available in several very different sidewall treatments: wide whitewall, redline, RWL, and blackwall. American Classic offers whitewall and redline versions, BFGoodrich offers a raised white letter treatment, and Dunlop offers a blackwall appearance. All of them fit the same basic size, but they create very different visual impressions on the car.

That matters on an Avanti because the body design blends classic styling cues with a more modern low-slung stance. A whitewall or redline can push the car toward a stronger retro presentation, while RWL and blackwall choices keep the look more contemporary and performance-oriented. The right choice depends less on fitment than on whether your Avanti II is being finished as a luxury-styled cruiser, a period-flavored custom, or a more understated driver.

Three brands cover the 215/60R15 fitment for 1991 Avanti vehicles: American Classic, BFGoodrich, and Dunlop. American Classic focuses on whitewall and redline radial options, BFGoodrich brings a raised white letter Radial T/A style, and Dunlop offers the Sport Classic in blackwall form. All three serve the same basic fitment but speak to different tastes in appearance and era cues.

For many Avanti owners, brand choice follows the kind of personality they want the car to project. American Classic tends to appeal to owners who want more visual nostalgia, BFGoodrich suits a stronger muscle-era visual attitude, and Dunlop fits buyers who prefer a cleaner performance-touring look. Once you have that direction in mind, compare each tire’s rim-width range, load rating, and speed rating instead of choosing by brand name alone.

For a 1991 Avanti in 215/60R15, the BFGoodrich Radial T/A and Dunlop Sport Classic differ in sidewall appearance, speed rating, load rating, and approved wheel details. The BFGoodrich uses an RWL sidewall, carries a 93S rating with a 112 mph speed ceiling, supports 1,411 pounds at 35 psi, and fits 6.00 to 7.50-inch rims. The Dunlop uses a blackwall sidewall, carries a 94V rating with a 149 mph speed ceiling, supports 1,477 pounds, and also fits a 15-inch rim.

Those differences make the choice as much about character as specification. The BFGoodrich gives the Avanti a more assertive American performance look, while the Dunlop keeps the presentation cleaner and more understated. If your wheel width falls near the narrow end of the fitment range, check that first, then decide whether the visual style and speed rating align with how you actually drive and present the car.

The 215/60R15 tires used on 1991 Avanti vehicles fit 15-inch rims, but the approved rim-width range depends on the exact product. American Classic versions cover 5.50 to 7.50 inches, while the BFGoodrich Radial T/A covers 6.00 to 7.50 inches. That difference is small, but it matters if your Avanti II has a wheel near the narrow edge of the allowable range.

Wheel width has a direct effect on how the tire sits, how the sidewall looks, and whether the contact patch shape stays within the tire maker’s intended range. A product that works well on a 5.50-inch rim may not share the same approval on a 6.00-inch minimum tire, even though both are 215/60R15. Measure the wheel, not just the tire currently mounted on it, before making a final choice.

The 215/60R15 radial options for 1991 Avanti do not carry tube-type markings in the size information here, so they are treated as tubeless radial products. That matches what most buyers would expect for a 1991 specialty coupe using a modern metric radial size on 15-inch wheels. Tube-type fitment is not the normal starting point for this application.

Even so, wheel condition still matters. If the car has original or older wheels, inspect the bead seats, valve-stem holes, and sealing surfaces carefully, because corrosion or prior repairs can affect whether a tubeless tire seals correctly. If you are working with specialty wheels or unusual restoration circumstances, it is wise to have the installer inspect the wheel before mounting the tire.

Yes, the available 1991 Avanti tire choices all share the same 215/60R15 size and 15-inch rim diameter, so they are intended for the same basic wheel diameter. The only setup detail that still needs attention is wheel width, because some products start at a 5.50-inch approved rim while others start at 6.00 inches. Diameter compatibility is straightforward, but width approval remains tire-specific.

That means an original 15-inch Avanti wheel can often accept more than one product style, from whitewall to blackwall, without changing wheel diameter. The smart next step is confirming the actual width and condition of the wheel so the tire you choose falls squarely within its approved range. That is especially important if the car has been modified at any point in its life.

A 1991 Avanti should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age rubber prematurely. Keep the tires at proper inflation and move the car periodically so one section of the tread is not carrying the load for months at a time. Radial tires generally resist storage flat-spotting better than older bias-ply designs, but long static periods are still hard on any collector-car tire.

If the Avanti will sit for an extended season, clean the tires, avoid petroleum-based dressings, and consider stands or tire cradles if the storage period will be especially long. A breathable car cover and stable indoor temperatures help the whole vehicle, not just the tires. Good storage habits preserve the sidewalls, keep the ride smoother when the car returns to use, and reduce the chance of discovering cracking right before an event or tour.

On a 1991 Avanti, tire life should be judged more by age and condition than by tread depth alone, because collector and specialty cars often accumulate limited miles. A good rule is to begin evaluating tires closely once they reach five to seven years of age and to treat ten years as a serious replacement point regardless of remaining tread. The DOT date code on the tire sidewall is the best way to confirm age.

That approach matters on an Avanti II because a low-mile car can still carry tires that look decent at a glance but have aged internally. Heat cycles, storage conditions, inflation history, and exposure to sunlight all affect rubber over time. If the tires are older, have sidewall cracking, or show any vibration or pressure-loss issues, replacement becomes a maintenance decision rather than a mileage decision.

Tires on a 1991 Avanti should be inspected before every drive and more carefully before any long outing. Check inflation, sidewall cracking, cuts, bulges, uneven wear, embedded debris, and any signs that the tire is losing air. On a collector car that may sit between drives, a quick visual check is not enough if the car has been idle for weeks or months.

A more thorough inspection every season is a sensible baseline, especially if the car attends tours, shows, or highway trips. Run your hand across the tread to feel for irregular wear and look closely at the valve stems as part of the same check. Catching age-related issues early is far easier than dealing with a failure after the car is already loaded and on the road.

A 1991 Avanti Avanti II belongs to an era when radial construction was the normal passenger-car standard, and the size used here is 215/60R15. That points you toward a modern radial fitment rather than an older bias-ply or early alphanumeric replacement path. Sidewall treatment could vary with owner taste, market presentation, or later replacement history, so the construction and size matter more than assuming one universal cosmetic style.

If originality is important, start by confirming the tire information from the car itself, period brochures, service literature, or marque specialists familiar with late Avanti production. Low-volume specialty cars sometimes differ from mainstream domestic models in small presentation details. Staying with the correct size and radial construction will usually put you on the right foundation before you narrow the choice to blackwall, whitewall, redline, or raised white letter styling.

Yes, correct tire fitment matters on a 1991 Avanti if the car is being judged for authenticity or overall presentation. Judges and knowledgeable enthusiasts often notice whether the tire size, construction type, and sidewall style suit the car’s era and intended appearance. A 215/60R15 radial is the right fitment direction for this application, but the visual message of a wide whitewall differs sharply from a blackwall or raised white letter tire.

That does not mean one sidewall is automatically wrong in every setting, because event standards can vary and some shows reward overall period flavor rather than factory-line exactness. The safest approach is to match the tire’s look to the way your Avanti is being presented and then check with Avanti clubs or event organizers if judging is a priority. On a specialty car, small visual details carry more weight than many owners expect.

For the 1991 Avanti in 215/60R15, the American Classic whitewall and American Classic redline share the same basic size, radial construction, 15-inch rim diameter, 5.50 to 7.50-inch approved rim-width range, 1,411-pound load rating at 35 psi, and asymmetrical tread family. The major distinction is cosmetic: one uses a 2-inch whitewall and the other uses a redline sidewall treatment. Their core fitment role is the same.

That makes the choice almost entirely about how you want the Avanti II to read visually. The whitewall pushes the car toward a more formal luxury-oriented presentation, while the redline gives it a sportier period-custom tone without changing the underlying size. If the car is being restored to a very specific appearance, compare photos, original sales material, and club knowledge before settling on the sidewall style.

Yes, 1991 Avanti tires in 215/60R15 can be suitable for highway driving when they are in good condition, correctly inflated, and matched to the car’s wheels. The available speed ratings in this size include S, with a 112 mph ceiling, and V, with a 149 mph ceiling, depending on the tire. Those figures are well above normal U.S. highway speeds, although real-world safety depends just as much on the age of the tire and the condition of the car itself.

An Avanti II is a specialty grand touring car, so highway confidence also depends on suspension condition, alignment, brakes, and how long the car has been sitting between drives. A higher speed rating does not override old rubber or deferred maintenance. If the tires are fresh, the pressures are correct, and the chassis is sorted, the tire size itself is not an obstacle to normal highway use.

Inflation pressure on a 1991 Avanti should follow the vehicle’s factory guidance first, with the tire maker’s maximum-pressure marking understood as a load-and-pressure limit rather than a universal running recommendation. In the available 215/60R15 products, one common load figure is 1,411 pounds at 35 psi, while another reaches 1,477 pounds. Those numbers should not be transferred loosely from one tire to another without checking the exact tire you are using.

The best practice is to verify the owner’s manual or original placard for the car’s intended operating pressure and then compare that with the sidewall information on the tire you choose. The right pressure supports ride quality, tread wear, and handling balance. If the car carries unusual weight distribution, aftermarket suspension parts, or non-original wheels, an experienced alignment or tire specialist can help fine-tune from a safe baseline.

Before a longer drive in a 1991 Avanti, inspect every tire for cracks, cuts, bulges, irregular wear, and proper cold inflation, and confirm that the spare is usable as well. Look closely at the sidewalls and valve stems, especially if the car has spent long periods parked. On a low-volume specialty car, tire condition should be part of a broader pre-trip inspection rather than a last-minute glance.

A longer outing is also the right time to check wheel balance, lug-nut torque, steering response, and any vibration that may have appeared during recent drives. Because collector cars often age out of their tires before they wear them out, appearance alone is not enough. A careful pre-drive inspection lowers the risk of turning a pleasant grand-touring trip into a roadside problem.
