The 1989 Mazda RX-7 sits squarely in the FC-generation era, when Mazda’s rotary sports car blended light weight, sharp handling, and a distinctly late-1980s Japanese performance character. Buyers looking at one today are often balancing originality, road manners, and the specific setup of the exact sub-model. Tire fitment for the 1989 Mazda RX-7 stays in radial construction, but size changes across the range from 185/70R14 to 205/60R15 and 205/55R16. That opens up meaningful choice in blackwall, raised white letter, and whitewall presentations across several tire series and brands. The right selection starts with the correct sub-model and wheel diameter, then moves to appearance, intended use, and overall fitment condition.
Which Tire Size Is Right for The 1989 Mazda RX-7
The 1989 Mazda RX-7 uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All three are radial sizes, but they are split across 14-inch, 15-inch, and 16-inch rims, so confirming the car’s actual wheel setup comes first. Once that is established, the decision shifts to tire style, brand, series, and whether the goal is a more original-looking presentation or a more modern performance-oriented radial choice.
185/70R14 is a metric radial size with a nominal section width of 185 millimeters, a 70-series profile, and fitment for a 14-inch rim. On the 1989 Mazda RX-7, this size suits the sub-models that use the smaller factory wheel diameter and keeps the fitment in the vehicle’s original radial construction. Available choices include blackwall and wide whitewall styles from BFGoodrich, Avon, Dunlop, Michelin, and Vredestein across series such as Silvertown Radial, CR6ZZ, Sport Classic, Michelin XAS, and Sprint Classic. It is the size to evaluate when preserving the correct 14-inch wheel setup matters as much as the tire’s appearance or road character.
205/60R15 is a metric radial with a 205-millimeter section width, a 60-series profile, and a 15-inch rim diameter. For the 1989 Mazda RX-7, this size belongs to specific mid-range configurations, making wheel confirmation important before selecting a tire. Product choices include blackwall, raised white letter, and wide whitewall presentations from Michelin, American Classic, Coker Classic, and BFGoodrich, with series such as Primacy 3, Star Series, American Classic Radial, and Radial T/A. This size is a strong focal point when the car needs the correct 15-inch fitment but the owner also wants to choose between sportier sidewall styling and a more restoration-oriented look.
205/55R16 is a metric radial size that combines a 205-millimeter section width with a lower 55-series profile on a 16-inch rim. On the 1989 Mazda RX-7, this size is used on the higher-spec sub-models that carry the largest wheel diameter in the range. Available tires include blackwall and wide whitewall options from BFGoodrich, Michelin, and American Classic, spanning series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Michelin SX MXX3 N2, and American Classic Radial. This is the size to focus on when the car has its correct 16-inch setup and the buyer wants to balance sporty late-1980s character with appearance preferences.
Sub-model fitment matters on the 1989 Mazda RX-7 because the range is split across three different tire sizes and three different rim diameters. Identifying the exact version of the car is the first step, since the tire choice changes with the Base, Convertible, GXL-family, GTU-family, and Turbo configurations.

1989 Mazda RX-7 Base
The 1989 Mazda RX-7 Base uses the 185/70R14 radial size, placing it on the smallest wheel diameter in the model range. That makes the main decision less about alternate fitments and more about choosing the right 14-inch radial style, series, and appearance for the car’s intended use.
The 1989 Mazda RX-7 Convertible uses the 205/60R15 radial size, which is shared with some other sub-models but not the entire lineup. Tire selection here starts with keeping the 15-inch fitment correct, then comparing blackwall, raised white letter, or whitewall presentations depending on the look you want.
The 1989 Mazda RX-7 GTU uses the 205/55R16 radial size, matching the larger-wheel fitment used on the higher-spec performance variants. That means the focus should be on the correct 16-inch radial options and on confirming that the car still retains the proper wheel setup before choosing among available tire series.
The 1989 Mazda RX-7 GTUs also uses the 205/55R16 radial size, keeping it aligned with the 16-inch fitment found on other upper-range versions. Tire selection is therefore centered on choosing the right radial style and series for that wheel diameter rather than sorting through multiple primary sizes.
The 1989 Mazda RX-7 GXL uses the 205/60R15 radial size, making it part of the 15-inch fitment group within the lineup. The practical choice is between the available tire styles and series in that size while making sure the wheel diameter and overall setup still match the car.
The 1989 Mazda RX-7 GXL 2+2 uses the 205/60R15 radial size, the same basic fitment used by other 15-inch RX-7 sub-models for this year. That keeps the selection process straightforward: confirm the 15-inch wheels, then choose the radial tire that best suits the car’s appearance and driving plans.
The 1989 Mazda RX-7 Turbo uses the 205/55R16 radial size, placing it in the 16-inch group with the GTU variants. Buyers should concentrate on that specific wheel diameter and compare the available radial series based on whether the goal is a sport-focused blackwall look or a more unusual whitewall presentation.
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.

These 1989 Mazda RX-7 tire FAQs focus on the three correct size groups, the sub-model differences between 14-inch, 15-inch, and 16-inch fitments, and the practical choices in radial style, appearance, and road-use preparation.
Tire Size & Fitment
What tire size fits a 1989 Mazda RX-7?
The 1989 Mazda RX-7 uses three different tire sizes depending on sub-model: 185/70R14, 205/60R15, and 205/55R16. All are radial tire sizes, but they correspond to different wheel diameters, so there is not one universal fitment for every 1989 RX-7 configuration.
The key step is identifying the exact sub-model and confirming the wheel diameter currently on the car. A Base uses 185/70R14, Convertible, GXL, and GXL 2+2 use 205/60R15, while GTU, GTUs, and Turbo use 205/55R16. If the car has been changed from its original wheels, measure the rim before choosing tires.
What size rim does a 1989 Mazda RX-7 use?
A 1989 Mazda RX-7 can use a 14-inch, 15-inch, or 16-inch rim depending on sub-model. The Base uses a 14-inch rim with 185/70R14 tires, Convertible and GXL-family models use a 15-inch rim with 205/60R15 tires, and GTU-family and Turbo models use a 16-inch rim with 205/55R16 tires.
That matters because the tire size and rim diameter must match exactly. A 15-inch tire does not mount on a 14-inch or 16-inch wheel, even if the section width looks close. On an older RX-7, it is worth checking the actual wheel size at the car, since aftermarket wheels or swapped factory wheels can change what tire is appropriate.
Do all 1989 Mazda RX-7 sub-models use the same tire size?
No. The 1989 Mazda RX-7 lineup is split across three tire sizes, so sub-model selection directly affects fitment. The Base uses 185/70R14, the Convertible, GXL, and GXL 2+2 use 205/60R15, and the GTU, GTUs, and Turbo use 205/55R16.
That means tire shopping starts with the exact version of the car, not just the year and model name. It also means wheel diameter needs to be confirmed before any comparison of brands or tire series begins. Once the sub-model is pinned down, the choice becomes much easier because every fitment here stays within radial construction.
Choosing the Right Tire
What should I consider when choosing a 1989 Mazda RX-7 tire?
Start with the correct tire size for the exact 1989 Mazda RX-7 sub-model and the wheel diameter actually on the car. After that, compare radial construction details such as tire series, sidewall style, rim-width compatibility, load figures where shown, and the overall look you want for the car.
A Base on 185/70R14 presents a different buying decision than a Turbo on 205/55R16. Some owners want a clean blackwall sport look, while others prefer a whitewall or raised white letter presentation for a more distinctive appearance. Matching the tire to the car’s use, wheel setup, and visual goals is more important than choosing by brand name alone.
What sidewall styles are available for 1989 Mazda RX-7 tires?
Sidewall choices for the 1989 Mazda RX-7 include blackwall, wide whitewall, and raised white letter depending on tire size. Blackwall is the most common style across the 14-inch, 15-inch, and 16-inch fitments, while wide whitewall options appear in all three size groups and raised white letter appears in 205/60R15.
That variety matters because sidewall styling changes the character of the car even when the size remains correct. A blackwall tends to preserve a more understated sport-coupe look, while whitewall and raised white letter options create a more customized or restoration-minded presentation. The right choice depends on the exact wheel size and the visual direction of the car.
What brands offer tires for the 1989 Mazda RX-7?
Tires for the 1989 Mazda RX-7 are available from BFGoodrich, Michelin, Avon, Dunlop, Vredestein, American Classic, and Coker Classic depending on size. Brand availability changes by fitment, so the 14-inch, 15-inch, and 16-inch RX-7 sizes do not all share the same mix of tire lines.
The practical approach is to narrow the search to the correct size first, then compare the brands that actually serve that wheel diameter. From there, look at sidewall style, tire series, and rim-width compatibility rather than assuming one brand covers every need. That keeps the choice focused on fitment and intended appearance instead of broad brand preference.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Mazda RX-7?
A period-style 1989 Mazda RX-7 tire starts with the correct sub-model size and wheel diameter, then moves to the visual presentation that best suits the car. Blackwall tires keep a sport-oriented late-1980s look, while selected wide whitewall and raised white letter options create a more customized or collector-oriented appearance.
Because the RX-7 range uses three different fitments, the first priority is keeping the car on its proper 14-inch, 15-inch, or 16-inch setup. After that, compare tire series and sidewall style in the correct size. Owners pursuing exact originality should cross-check the car against marque references or historical documentation before treating any current sidewall style as exact.
How does tire construction affect the appearance of a restored 1989 Mazda RX-7?
For the 1989 Mazda RX-7, the primary fitments are already radial, so the construction question is less about bias-ply versus radial appearance and more about how the chosen radial tire is presented. Sidewall treatment, overall tread style, and tire series have a greater effect on the restored look than construction type alone.
That makes size accuracy especially important on a restoration-minded RX-7. The right 14-inch, 15-inch, or 16-inch radial fitment helps preserve the proportions intended for that sub-model, while a mismatched wheel and tire package can change the car’s stance noticeably. Once the fitment is correct, the sidewall style becomes the main visual decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Mazda RX-7?
Yes. Modifications can change tire fitment on a 1989 Mazda RX-7 even when the original size for the sub-model is known. Aftermarket wheels, altered wheel width, suspension changes, or body modifications can affect clearance, steering travel, and the relationship between the tire and the fender opening.
A careful check should include actual wheel diameter, wheel width, and how much room exists at full steering lock and under compression. This matters even more on an RX-7 because the model range already spans 14-inch, 15-inch, and 16-inch fitments. Any car that no longer carries its stock wheel setup should be measured rather than assumed.
What should I inspect before driving a 1989 Mazda RX-7 on new tires?
Before driving a 1989 Mazda RX-7 on new tires, inspect the wheels for damage, confirm the tire size matches the car’s actual rim diameter, and check that inflation is set correctly for the tires being installed. It is also smart to look over suspension and steering components so the new tires are not asked to compensate for worn hardware.
A road-ready inspection should also include sidewall clearance, tread-to-body clearance, lug hardware condition, and signs of rubbing from previous tires. Older enthusiast cars may have sat for long periods, so it helps to watch for air loss, vibration, or uneven contact once the car is back in use. A short initial drive and recheck can catch issues early.
How should 1989 Mazda RX-7 tires be maintained?
1989 Mazda RX-7 tires should be maintained with regular pressure checks, periodic visual inspections, and close attention to age and condition, especially on low-mileage collector cars. Look for cracking, bulges, cuts, uneven wear, and any sign of recurring air loss, since time can affect tires even when the car is not driven often.
Storage conditions matter as much as mileage on an older sports car. Keeping the RX-7 away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires between drives. It also helps to inspect them before longer trips, because a car that feels fine on short outings can still reveal age-related issues once speed and distance increase.
