The 1986 Mazda RX-7 sits at an interesting point in the model’s development, blending the lightweight rotary-sports-car character enthusiasts expect with trim levels that moved from a simple driver’s coupe to more upscale and performance-focused versions. Tire selection matters here because this RX-7 does not use one universal setup across the lineup. The Base, GXL, and Turbo each use a different radial tire size on a different rim diameter. That creates real choice not only in size, but also in sidewall style, tire series, and overall presentation, from blackwall sport radials to whitewall options. Getting the right tire starts with matching the exact sub-model and wheel diameter before comparing appearance or driving priorities.
Which Tire Size Is Right for The 1986 Mazda RX-7
Three tire sizes apply to the 1986 Mazda RX-7, and they vary by sub-model and rim diameter rather than by interchangeable style choice alone. The first step is confirming whether the car is a Base, GXL, or Turbo and then verifying the wheel diameter on the car, since the lineup uses 14-inch, 15-inch, and 16-inch radial fitments. Once that is settled, the decision shifts to tire series, sidewall treatment, and the kind of road use or period-inspired appearance you want.
A 185/70R14 tire uses a 185-millimeter section width, a 70-series profile, radial construction, and a 14-inch rim. On the 1986 Mazda RX-7, this size is the smaller radial fitment used on the Base model and keeps the selection focused on proper wheel match first. Available choices include blackwall sport and classic-series tires from Avon, Dunlop, Michelin, and Vredestein, along with a BFGoodrich Silvertown Radial in a wide whitewall presentation. This size makes sense when the goal is to stay with the Base-model wheel setup while choosing between a more traditional look and a more understated blackwall appearance.
A 205/60R15 tire is a metric radial with a 205-millimeter section width, 60-series aspect ratio, and 15-inch rim diameter. This size serves the 1986 Mazda RX-7 GXL and represents a distinct step away from the Base-model 14-inch setup, so it should be matched to the correct wheels rather than treated as a universal RX-7 tire. Product choices include blackwall, wide whitewall, and raised white letter sidewall styles from Michelin, American Classic, Coker Classic, and BFGoodrich. It is the right path for an RX-7 that needs the GXL fitment while still leaving room to prioritize either a sportier look or a more restoration-oriented presentation.
A 205/55R16 tire keeps the same 205-millimeter nominal width as the 15-inch option but uses a lower 55-series profile on a 16-inch rim. On the 1986 Mazda RX-7, this is the Turbo fitment, so the important question is not whether it resembles the other RX-7 sizes, but whether the car actually has the Turbo wheel setup. Most choices in this size lean toward blackwall performance-oriented radial series from BFGoodrich and Michelin, though a wide whitewall American Classic Radial is also available. This size suits owners who need the 16-inch Turbo specification and want to compare performance-style tires against a more distinctive visual treatment.
Sub-model fitment matters on the 1986 Mazda RX-7 because each covered version uses its own tire size and wheel diameter. Identifying whether the car is a Base, GXL, or Turbo is the key first step before comparing tire series, sidewall styles, or other product details.

1986 Mazda RX-7 Base
The 1986 Mazda RX-7 Base uses a 14-inch radial fitment centered on 185/70R14. That keeps the tire search straightforward, but the right choice still depends on whether the priority is a blackwall sport-classic look or a more distinctive wide whitewall presentation.
The 1986 Mazda RX-7 GXL uses a 15-inch radial setup built around 205/60R15. Tire selection here comes down to confirming the correct wheel size and then deciding between blackwall, raised white letter, or wide whitewall styles within that fitment.
The 1986 Mazda RX-7 Turbo uses a 16-inch radial tire size, making it distinct from the Base and GXL. That makes wheel verification especially important before shopping, after which the real comparison becomes performance-oriented blackwall series versus a more unusual wide whitewall option.
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 1986 Mazda RX-7 tire FAQs focus on the questions that matter most for this car: which size matches each sub-model, how wheel diameter affects selection, and how to compare available radial choices by style, brand, and intended use.
Tire Size & Fitment
What tire size fits a 1986 Mazda RX-7?
The 1986 Mazda RX-7 uses three different tire sizes depending on sub-model. The Base uses 185/70R14, the GXL uses 205/60R15, and the Turbo uses 205/55R16. All three are radial sizes, and each one corresponds to a different wheel diameter.
The practical takeaway is that there is no single tire size for every 1986 RX-7. Start by confirming the exact sub-model, then verify the wheels currently on the car, especially if it has changed hands or has been modified over time. Matching the tire to the correct rim diameter comes before comparing brands, sidewall treatments, or tire series.
What size rim does a 1986 Mazda RX-7 use?
Rim diameter depends on which 1986 Mazda RX-7 you have. The Base uses a 14-inch rim with 185/70R14 tires, the GXL uses a 15-inch rim with 205/60R15 tires, and the Turbo uses a 16-inch rim with 205/55R16 tires. Each size is tied to its own wheel diameter.
Checking the actual wheel on the car is important because the RX-7 lineup spans three diameters in the same model year. A tire in the correct width and profile still will not work if the rim diameter is wrong. Reading the existing tire sidewall and measuring the wheel setup can prevent ordering a size meant for a different RX-7 sub-model.
Why does the 1986 Mazda RX-7 have more than one tire size?
The 1986 Mazda RX-7 has more than one tire size because the Base, GXL, and Turbo use different wheel and tire packages. Those differences are reflected in 185/70R14, 205/60R15, and 205/55R16 fitments. The tire size changes with the sub-model rather than serving as a universal year-wide specification.
That matters because tire selection begins with identifying the exact version of the car, not just the year and model name. It also means a used RX-7 may no longer wear its original wheel diameter, so a quick inspection is worthwhile. Once the correct size is confirmed, you can narrow the choice by appearance, series, and intended driving use.
Choosing the Right Tire
What should I consider when choosing a tire for a 1986 Mazda RX-7?
Start with the exact fitment for the car: 185/70R14 for Base, 205/60R15 for GXL, or 205/55R16 for Turbo. From there, compare the available radial options by rim-width compatibility, sidewall style, tire series, and the kind of visual character you want, since some sizes lean toward sport blackwalls while others also include whitewall or raised white letter choices.
A sensible final check is how the RX-7 is actually used. A car kept close to its original appearance may call for a more traditional-looking radial, while a frequently driven example may lead you toward a more modern performance-style tire. Wheel size, stance, and clearance should all be confirmed before settling on a specific product.
What sidewall styles are available for 1986 Mazda RX-7 tires?
Sidewall choices for the 1986 Mazda RX-7 include blackwall, wide whitewall, and raised white letter depending on tire size. Blackwall options appear across all three fitments, wide whitewalls are available in each of the covered sizes, and raised white letter appears in 205/60R15 through the BFGoodrich Radial T/A.
That gives the RX-7 owner a broader appearance range than many mid-1980s sports cars. The right choice depends on whether the car is being kept visually understated, given a more custom or nostalgic presentation, or matched to a certain period-inspired style. Sidewall treatment does not change the need to stay with the correct size and rim diameter for the sub-model.
What brands offer tires for the 1986 Mazda RX-7?
Tires for the 1986 Mazda RX-7 are available from BFGoodrich, Michelin, Avon, Dunlop, Vredestein, American Classic, and Coker Classic. Brand availability depends on size, so the full range differs between the Base, GXL, and Turbo fitments. Some sizes emphasize classic touring or vintage-style radial lines, while others include more performance-oriented modern series.
Brand choice should come after confirming the correct size for the specific RX-7. Once the fitment is settled, compare how each brand’s available series aligns with the car’s intended look and use. It is more useful to compare the actual product characteristics in the proper size than to choose a brand first and try to make the fitment work afterward.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Mazda RX-7?
A period-style 1986 Mazda RX-7 tire choice begins with the correct sub-model size: 185/70R14, 205/60R15, or 205/55R16. From there, the visual direction matters. Blackwall radials usually preserve a more understated sports-car look, while certain wide whitewall offerings create a much more customized or distinct presentation within the correct size.
Owners pursuing a restoration-oriented result should separate accurate fitment from exact originality. The right starting point is the proper size and wheel diameter for the car, then a sidewall style that matches the intended look. If exact historical presentation matters, compare your choice against marque references, period photos, or other vehicle-specific documentation before making a final decision.
How does tire construction affect the appearance of a restored 1986 Mazda RX-7?
Construction is straightforward on the 1986 Mazda RX-7 because the covered fitments are radial tires, so the appearance differences come more from tire series and sidewall style than from choosing between bias-ply and radial. A blackwall radial can look subtle and sporty, while a wide whitewall or raised white letter treatment changes the car’s visual character much more dramatically.
That means restoration-minded owners should focus less on construction type and more on the look created by the actual tire offered in the correct size. Proportion, sidewall treatment, and wheel diameter all contribute to how authentic or customized the finished car appears. Keeping the proper sub-model fitment is the foundation for any appearance-driven tire decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Mazda RX-7?
Yes. Modifications can affect tire fitment on a 1986 Mazda RX-7 even when the tire size itself is correct for a Base, GXL, or Turbo. Aftermarket wheels, different offsets, lowered suspension, altered springs, or body changes can all influence how much room the tire has during steering and suspension travel.
That is especially important on a model year that already uses three wheel diameters across the lineup. A used RX-7 may not still carry its original wheel setup, so check the actual rim size and width before choosing a tire. Clearance at the fender, inner wheelhouse, and steering range should be verified anytime the car departs from a stock-style configuration.
What should I inspect before driving a 1986 Mazda RX-7 on new tires?
Before driving a 1986 Mazda RX-7 on new tires, inspect the wheels for damage, confirm the tire size matches the sub-model’s rim diameter, and make sure inflation is set correctly for the tire being used. It is also wise to look over valve stems, lug hardware, alignment condition, and any signs of rubbing around the suspension or fender edges.
A short, careful shakedown drive is a good final step. Pay attention to steering feel, vibration, pull, and clearance as the car moves through turns and bumps. On an older sports car, tires often reveal pre-existing issues such as worn suspension parts or alignment problems, so the first miles should be used to confirm the whole setup is working together properly.
How should tires on a collector 1986 Mazda RX-7 be maintained?
Tires on a collector 1986 Mazda RX-7 should be maintained with regular pressure checks, visual inspections, and careful storage habits. Look for cracking, cuts, bulges, uneven tread wear, and slow air loss, especially if the car spends long periods parked. Collector cars often age their tires by time and storage conditions long before tread is actually worn out.
Clean, dry storage away from prolonged sunlight, excess heat, and ozone-producing equipment helps preserve tire condition. Driving the car periodically can also help reveal vibration, flat-spotting, or handling changes before a longer trip. Even with low mileage, an RX-7 benefits from routine tire inspection because age-related deterioration is easy to miss on a lightly used vehicle.
