The 1991 Mazda RX-7 sits at an interesting point in the model’s evolution, carrying the lightweight, rotary-powered character that made the second-generation car a favorite with drivers who value balance and responsiveness. It is also a year where trim level matters more than ever for tire selection. The 1991 Mazda RX-7 uses radial tires in two different sizes, with 205/60R15 fitted to Base and Convertible models and 205/55R16 fitted to the Turbo. Available choices range from blackwall performance-oriented radials to wide whitewall and raised white letter styles. The right decision starts with confirming the exact sub-model and wheel diameter, then matching the tire’s look and road-use intent to the car.
Which Tire Size Is Right for The 1991 Mazda RX-7
Two tire sizes apply to the 1991 Mazda RX-7, and the correct choice depends on the exact sub-model and wheel diameter. Base and Convertible models use a 15-inch radial fitment in 205/60R15, while the Turbo uses a 16-inch radial fitment in 205/55R16. Before comparing brands, sidewall styles, or tire series, confirm whether the car is a Base, Convertible, or Turbo and verify the wheels currently on the vehicle.
In 205/60R15, the 205 identifies the tire's nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 15 is the rim diameter in inches. On the 1991 Mazda RX-7, this is the primary fitment for Base and Convertible models, making it the size to match when keeping those configurations on their original wheel diameter. Available choices include blackwall, wide whitewall, and raised white letter styles from brands such as Michelin, American Classic, Coker Classic, and BFGoodrich. That gives buyers room to choose between a more understated modern look, a restoration-oriented presentation, or a more traditional performance appearance.
In 205/55R16, the 205 is the nominal section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 16 is the wheel diameter in inches. For the 1991 Mazda RX-7, this size belongs with the Turbo, so it should be selected only after confirming that the car retains the correct 16-inch wheel setup. Product choices in this size include blackwall performance-focused series from BFGoodrich and Michelin, along with a wide whitewall option from American Classic. Buyers usually land on this size by preserving Turbo fitment first, then narrowing the choice by intended appearance and the character of the tire series.
Sub-model fitment on the 1991 Mazda RX-7 is not the same across the range, so the trim name matters before choosing a tire. Base and Convertible cars share one radial size, while the Turbo moves to a different size on a different rim diameter.

1991 Mazda RX-7 Base
The 1991 Mazda RX-7 Base uses the 205/60R15 radial size on a 15-inch wheel. Tire selection here is mostly about choosing the right brand, sidewall treatment, and overall appearance while keeping the correct size for the Base configuration.
The 1991 Mazda RX-7 Convertible shares the 205/60R15 radial fitment used on the Base model. That keeps sizing straightforward, so the main decision becomes whether the car calls for a clean blackwall look, a wide whitewall presentation, or a raised white letter style.
The 1991 Mazda RX-7 Turbo uses the 205/55R16 radial size on a 16-inch wheel rather than the 15-inch fitment used by the other sub-models. That makes wheel confirmation especially important before comparing tires, since performance-oriented blackwall choices and a whitewall alternative are both available in this size.
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.

Tire Size & Fitment
What tire size fits a 1991 Mazda RX-7?
The 1991 Mazda RX-7 uses two different radial tire sizes depending on sub-model. Base and Convertible models use 205/60R15, while the Turbo uses 205/55R16. Both are metric radial sizes, but they are tied to different wheel diameters, so they are not the same fitment choice across the range.
The first step is identifying whether the car is a Base, Convertible, or Turbo, then confirming the wheel diameter currently on the car. Many older sports cars have seen wheel changes over time, so the actual wheel setup should match the intended tire size before comparing brands, sidewall styles, or tire series.
What size rim does a 1991 Mazda RX-7 use?
A 1991 Mazda RX-7 uses either a 15-inch or 16-inch rim, depending on sub-model. The Base and Convertible use the 205/60R15 tire on a 15-inch rim, while the Turbo uses the 205/55R16 tire on a 16-inch rim. Rim diameter is part of the tire size itself and must match exactly.
That makes wheel confirmation one of the most important fitment checks on this car. A 15-inch tire cannot be mounted on a 16-inch wheel, and a 16-inch tire cannot be mounted on a 15-inch wheel. If the RX-7 has aftermarket wheels, verify both diameter and width before settling on a tire.
Do all 1991 Mazda RX-7 sub-models use the same tire size?
No, the 1991 Mazda RX-7 does not use one tire size across every sub-model. The Base and Convertible share 205/60R15, but the Turbo uses 205/55R16. That split means the correct tire choice depends on the specific version of the car rather than the model name alone.
This matters because the size difference also brings a wheel-diameter difference with it. A buyer choosing tires by year and model only can easily end up in the wrong category without checking the sub-model first. On an RX-7 that has been modified, the wheel currently fitted should always be checked before ordering replacement tires.
Choosing the Right Tire
What should I consider when choosing a tire for a 1991 Mazda RX-7?
Start with the correct size for the exact sub-model: 205/60R15 for the Base and Convertible, or 205/55R16 for the Turbo. From there, look at the tire’s construction, rim-width compatibility, load information where given, sidewall style, and the character of the tire series. Those factors shape both appearance and how the car presents on the road.
A blackwall radial usually suits a more understated or performance-oriented look, while wide whitewall and raised white letter options change the visual character of the car significantly. It also helps to think about how the RX-7 will be used, whether that means weekend driving, shows, or a more restoration-minded presentation built around period-style appearance.
What sidewall styles are available for 1991 Mazda RX-7 tires?
Sidewall choices for the 1991 Mazda RX-7 include blackwall, wide whitewall, and raised white letter styles, depending on tire size. The 205/60R15 fitment offers all three looks, while the 205/55R16 fitment includes blackwall options and a wide whitewall alternative. That creates a wider appearance range than many modern sport-compact applications.
The sidewall choice changes the car’s presentation more than many buyers expect. Blackwalls keep the look clean and restrained, raised white letters lean toward a traditional performance style, and wide whitewalls create a custom or restoration-oriented visual statement. Once the correct size is confirmed, sidewall style becomes one of the easiest ways to tailor the car’s personality.
What brands offer tires for the 1991 Mazda RX-7?
Tires for the 1991 Mazda RX-7 are available from Michelin, BFGoodrich, American Classic, and Coker Classic, depending on the size selected. The 205/60R15 fitment includes offerings from all four brands, while the 205/55R16 fitment includes BFGoodrich, Michelin, and American Classic. Each brand appears in radial construction for this application.
Brand choice matters most after the correct size and wheel diameter have been confirmed. At that point, the real comparison is between tire series, sidewall treatments, and the overall look the car needs. Some options lean toward a modern blackwall presentation, while others are aimed more at traditional styling or restoration-oriented appearance.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Mazda RX-7?
A period-style choice for a 1991 Mazda RX-7 starts with using the correct sub-model size first, then selecting a tire that matches the car’s intended presentation. For Base and Convertible models, 205/60R15 opens up blackwall, wide whitewall, and raised white letter options. For the Turbo, 205/55R16 keeps the proper wheel diameter while offering blackwall and wide whitewall choices.
The right answer depends on whether the car is being preserved with a sporty early-1990s look, customized for show use, or restored with a more traditional visual theme. Exact originality questions should be checked against marque-specific references, old photos, or owner documentation, since appearance options in the correct size are broader than one single historical presentation.
How does tire construction affect the appearance of a restored 1991 Mazda RX-7?
On a 1991 Mazda RX-7, tire construction is straightforward because the primary fitments are radial rather than bias-ply. That means the visual difference usually comes less from construction type and more from sidewall treatment, brand character, and the tire series selected. In practical terms, the appearance decision centers on blackwall, raised white letter, or wide whitewall styling.
A restored RX-7 can look notably different with each of those sidewall styles even when the size remains correct. Blackwalls tend to preserve a cleaner, more restrained sports-car presentation, while whitewall or raised white letter options push the car toward a more customized or period-flavored look. Keeping the proper size for the sub-model is still the first restoration requirement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Mazda RX-7?
Yes, modifications can affect tire fitment on a 1991 Mazda RX-7 even when the tire size itself is correct for the model. Aftermarket wheels, altered wheel width, suspension changes, or ride-height changes can all influence clearance and how the tire sits within the car’s wheel openings. That matters especially because this RX-7 uses both 15-inch and 16-inch fitments depending on sub-model.
A modified car should have its actual wheel diameter and width checked before replacement tires are chosen. Steering clearance, fender clearance, and the condition of suspension components also deserve attention. Even a stock-size tire can behave differently on a changed setup, so the physical wheel-and-vehicle combination should guide the final decision.
What should I inspect before driving a 1991 Mazda RX-7 on new tires?
Before driving a 1991 Mazda RX-7 on new tires, inspect the wheels for the correct diameter, check that the tires are seated properly, and confirm that inflation pressure matches the tire and wheel setup being used. It is also smart to look over suspension, steering, and brake components so the new tires are not being asked to compensate for worn hardware.
An older RX-7 should also be checked for clearance at full steering lock and through normal suspension travel, especially if it has non-original wheels or a changed ride height. After the first few drives, recheck pressure and look for any signs of rubbing or uneven wear. Those early inspections help catch setup issues before they become tire problems.
How should tires on a collector 1991 Mazda RX-7 be maintained?
Tires on a collector 1991 Mazda RX-7 should be maintained with regular pressure checks, visual inspections, and attention to age as well as tread depth. Even when the car is driven infrequently, sidewall cracking, flat spotting, cuts, bulges, and slow air loss can develop over time. Low-mileage collector use does not stop rubber from aging.
Storage conditions matter too. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires between drives. It is also worth moving the vehicle periodically or driving it enough to avoid long-term flat spotting. A quick inspection before each outing is a sensible habit on any lightly used RX-7.
