The 1982 Mazda RX-7 sits in the early years of Mazda’s rotary-powered sports car, when light weight, sharp proportions, and balanced handling defined the car’s appeal. For owners today, tire choice plays a big role in preserving that character because this RX-7 uses 13-inch radial fitments, with 185/70R13 and 165R13 both appearing across the model range. That creates a decision not just about size, but also about sub-model fitment, sidewall appearance, and whether a touring-style or sport-oriented radial better matches the car. Getting the right tire starts with confirming the exact RX-7 configuration and the wheels currently on the car.
Which Tire Size Is Right for The 1982 Mazda RX-7
Two primary tire sizes apply to the 1982 Mazda RX-7, and both are radial tires built for 13-inch rims. The correct choice depends first on the exact sub-model, since GS and GSL configurations use 185/70R13 while S models may use either 165R13 or 185/70R13. Once that is confirmed, the decision shifts to tire series, sidewall style, and the kind of driving or presentation the car is meant to have.
Fit(s): GS, GS w/aluminum wheels, GSL, GSL w/aluminum wheels, S, and S w/aluminum wheels
Construction: Radial|Rim: 13 in
185/70R13 is a metric radial size: 185 identifies the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 13 is the wheel diameter in inches. On the 1982 Mazda RX-7, this size suits the car’s period sports-car character while keeping a modern metric sizing convention. Available choices include BFGoodrich, Avon, Dunlop, Michelin, and Vredestein, with blackwall, redline, and wide whitewall presentations across series such as Silvertown Radial, CR6ZZ, Sport Classic, and Sprint Classic. This size is the key choice for GS and GSL fitment and also appears on S models, so exact configuration and wheel setup still matter.
165R13 is a Euro-metric radial size in which 165 indicates nominal section width in millimeters, R marks radial construction, and 13 is the rim diameter in inches. Because no aspect ratio is stated in the size itself, this format is commonly associated with a traditional taller-profile radial look. On the 1982 Mazda RX-7, 165R13 appears on S-model fitment, giving owners a narrower classic-style radial option. Michelin and Dunlop choices are available in blackwall form, making this size worth evaluating when preserving the intended stance, steering feel, or wheel pairing of an S configuration.
Sub-model fitment matters on the 1982 Mazda RX-7 because not every version uses the same tire size. GS and GSL models stay consistent with 185/70R13, while S models can use either 165R13 or 185/70R13, so the exact trim and wheel setup should be confirmed before choosing tires.

1982 Mazda RX-7 GS
The 1982 Mazda RX-7 GS uses the 185/70R13 radial size on a 13-inch rim. That keeps selection focused on comparing available tire series and sidewall treatments rather than deciding between multiple primary sizes.
The 1982 Mazda RX-7 GS w/aluminum wheels also uses 185/70R13 radial tires. Tire choice here comes down to the kind of appearance and road use desired, while still confirming that the wheel width matches the tire being considered.
The 1982 Mazda RX-7 GSL uses the 185/70R13 radial fitment. That makes it easier to compare blackwall and specialty sidewall options within the same size while keeping the car on its correct 13-inch tire diameter.
The 1982 Mazda RX-7 GSL w/aluminum wheels uses 185/70R13 radial tires as well. Buyers can concentrate on tire character, brand, and presentation, with wheel-width compatibility still worth checking before final selection.
The 1982 Mazda RX-7 S can use either 165R13 or 185/70R13, both in radial construction. That makes this the sub-model where confirming the actual wheel and existing fitment is especially important before choosing between a narrower classic-profile radial and a wider modern metric size.
The 1982 Mazda RX-7 S w/aluminum wheels also appears with both 165R13 and 185/70R13 radial fitments. Tire selection should start with the wheels currently on the car, then move to the preferred balance of traditional appearance, handling feel, and available product options.
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 1982 Mazda RX-7?
The 1982 Mazda RX-7 uses two primary radial tire sizes: 185/70R13 and 165R13. GS and GSL models use 185/70R13, while S models appear with either 165R13 or 185/70R13, both on 13-inch rims. That means the exact trim and wheel setup determine which size belongs on the car.
The practical step is to verify the specific sub-model and the wheels currently installed before choosing a tire. Many RX-7s have changed hands, and some may have different wheels than they left with, so checking the sidewall on the existing tire and confirming wheel width can prevent ordering the wrong size.
What size rim does a 1982 Mazda RX-7 use?
The 1982 Mazda RX-7 uses 13-inch rims with both of its primary tire sizes. Both 185/70R13 and 165R13 are built around a 13-inch wheel diameter, so the rim diameter stays consistent even though the tire widths and profiles vary by sub-model and application.
Rim diameter is only part of the fitment picture, so it helps to confirm wheel width as well before selecting a specific tire. Some 185/70R13 products call for wider rim ranges than 165R13 tires, and that can influence which tire series or sidewall treatment makes sense for the wheels on the car.
Why does the 1982 Mazda RX-7 have more than one tire size?
More than one tire size appears because the 1982 Mazda RX-7 was offered in different sub-model configurations. GS and GSL versions use 185/70R13, while S models may use either 165R13 or 185/70R13, so the size question is tied to trim level and wheel setup rather than one universal fitment.
That matters because the two sizes are not just different labels; they represent different tire profiles and product selections. A buyer should match the tire to the exact sub-model and wheel dimensions on the car, then decide whether the goal is a traditional narrow radial look or a broader selection in 185/70R13.
Choosing the Right Tire
What should I consider when choosing a 185/70R13 tire for a 1982 Mazda RX-7?
A 185/70R13 choice for a 1982 Mazda RX-7 starts with confirming that this is the correct primary size for the car, which it is for GS and GSL models and for some S configurations. From there, selection comes down to radial tire series, sidewall style, brand, rim-width compatibility, and the kind of road use or presentation the car is meant to have.
Some 185/70R13 options lean toward traditional appearance, while others have a stronger vintage-sport emphasis. It helps to compare the wheel width on the car against the approved rim-width range for the tire being considered, then decide whether blackwall, redline, or wide whitewall better suits the RX-7’s intended look.
What sidewall styles are available for 1982 Mazda RX-7 tires?
Sidewall choices for the 1982 Mazda RX-7 include blackwall, redline, and wide whitewall, depending on tire size and series. The broadest variety appears in 185/70R13, where blackwall options are joined by BFGoodrich Silvertown Radial versions with redline and 2-inch whitewall sidewalls.
That means sidewall style can be part of the decision once the correct size is confirmed. A blackwall tends to preserve a cleaner sports-car presentation, while a redline or wide whitewall creates a stronger visual statement, so the right choice depends on whether the RX-7 is being kept closer to a sporty period look or a custom appearance.
What brands offer tires for the 1982 Mazda RX-7?
Tires for the 1982 Mazda RX-7 are available from BFGoodrich, Avon, Dunlop, Michelin, and Vredestein across the applicable 13-inch radial sizes. Brand availability depends on the size, with 185/70R13 offering the widest spread of choices and 165R13 concentrating on Michelin and Dunlop products.
Brand alone should not be the only filter. A better approach is to start with the correct size, then compare each tire’s series character, sidewall treatment, and rim-width suitability so the final selection matches both the car’s configuration and the owner’s goals for appearance, road use, and overall period feel.
Restoration & Appearance
Which tire should I choose for a period-style 1982 Mazda RX-7?
A period-style 1982 Mazda RX-7 tire choice starts with using the correct primary size for the exact sub-model: 185/70R13 for GS and GSL, or 165R13 or 185/70R13 for S versions. From there, the most authentic-looking direction usually comes from a radial with a traditional profile, restrained sidewall design, and proportions that suit the car’s early-1980s shape.
That does not automatically mean one series or brand is the only correct answer, because restoration goals vary. Owners pursuing a historically faithful presentation should compare sidewall appearance carefully and, when exact originality matters, consult marque references, period photography, or restoration documentation before settling on a specific tire style.
How does tire construction affect the appearance of a restored 1982 Mazda RX-7?
On a restored 1982 Mazda RX-7, tire construction is straightforward because the primary fitments are radial rather than bias-ply. Even so, construction still influences appearance through sidewall shape, tread presentation, and the sizing format itself, especially when comparing the narrower classic-style 165R13 with the modern metric 185/70R13.
The visible effect is often as important as the mechanical fit. A blackwall radial can keep the car looking clean and sport-oriented, while redline or wide whitewall versions in 185/70R13 create a much different visual message, so restoration-minded owners should choose a tire that supports the car’s intended era feel rather than only chasing availability.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1982 Mazda RX-7?
Yes, modifications can affect tire fitment on a 1982 Mazda RX-7 even when the tire size itself is correct. Aftermarket wheels, altered wheel width, suspension changes, lowering, or body modifications can change clearance and can also affect whether a 165R13 or 185/70R13 works properly on the car.
A modified RX-7 should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before tires are chosen. It is also wise to inspect for rubbing marks and to compare the wheel setup side to side, since an otherwise correct radial size may still create issues when the chassis or wheels no longer match stock geometry.
What should I inspect before driving a 1982 Mazda RX-7 on new tires?
Before driving a 1982 Mazda RX-7 on new tires, inspect the wheels for damage, confirm lug hardware is correct, and make sure the selected tire size matches the car’s sub-model and wheel dimensions. Tire pressures should be set properly, and the sidewalls and tread should be checked after mounting to confirm the tires seated evenly.
A short initial road test is a smart follow-up. Pay attention to steering feel, vibration, pulling, or any sign of contact at full lock and over bumps, because these clues can reveal wheel-balance issues, alignment problems, or clearance concerns that should be corrected before the car is used for regular cruising or longer trips.
How should 185/70R13 and 165R13 tires on a collector 1982 Mazda RX-7 be maintained?
Collector-car tires on a 1982 Mazda RX-7 should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Both 185/70R13 and 165R13 radials should be watched for cracking, cuts, bulges, uneven wear, and gradual air loss, especially on a car that spends long periods parked rather than driven weekly.
Storage conditions matter nearly as much as mileage on a low-use RX-7. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the rubber, and moving the car occasionally or changing its resting position can help reduce flat spotting during long periods between drives.
