The 1983 Mazda RX-7 sits in the sweet spot of the first-generation FB rotary sports car, blending light weight, sharp proportions, and the distinct character that made the RX-7 such a standout among early 1980s imports. Tire choice matters on this car because fitment varies by sub-model, with 13-inch and 14-inch radial setups both in play. Depending on the exact version, the RX-7 uses 165R13, 185/70R13, or 195/60R14 tires, and the available choices range from blackwall performance-oriented radials to redline and wide whitewall styles in certain sizes. The right selection starts with the exact sub-model and wheel diameter, then moves to appearance, road use, and overall period feel.
Which Tire Size Is Right for The 1983 Mazda RX-7
Three primary tire sizes apply to the 1983 Mazda RX-7, and they do not all serve the same configuration. Fitment varies by sub-model and wheel package, with both 13-inch and 14-inch radial setups used across the range. The first step is confirming the exact sub-model and actual wheel diameter on the car, especially if aluminum wheels or later wheel changes are involved.
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 where 185 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 13 is the wheel diameter in inches. On the 1983 Mazda RX-7, this size is a primary fitment across several sub-models and keeps the car on a 13-inch wheel. Available choices include BFGoodrich, Avon, Dunlop, Michelin, and Vredestein, with blackwall, redline, and wide whitewall sidewall treatments depending on the tire series. This size suits buyers who want the most common 13-inch RX-7 fitment while still choosing between a traditional look and a more sport-focused presentation.
195/60R14 is a metric radial size that uses a 195-millimeter nominal section width, a 60-series profile, and a 14-inch wheel diameter. For the 1983 Mazda RX-7, this size applies to the Limited Edition and represents a distinct 14-inch fitment rather than an interchangeable variation of the 13-inch setups. The available product selection in this size centers on a blackwall Michelin MXV3-A, giving the car a distinctly modern-for-its-era low-profile radial appearance. This is the size to evaluate when the car retains its 14-inch wheel package and the goal is to preserve that specific stance and fitment character.
165R13 is a Euro-metric radial size in which 165 is the nominal section width in millimeters, R indicates radial construction, and 13 is the wheel diameter in inches. Because no aspect ratio is stated in this format, it is typically understood as a taller-profile Euro-metric radial style rather than a low-profile modern metric size. On the 1983 Mazda RX-7, this size appears on certain S models, with blackwall offerings from Michelin and Dunlop in series such as XAS, XAS-FF, and SP Sport Aquajet. It is worth considering when the car uses the narrower 13-inch setup and the goal is to stay close to that earlier radial sizing convention.
Sub-model fitment matters on the 1983 Mazda RX-7 because tire size is not uniform across the range. Some versions share the same 13-inch radial setup, while others use either an alternate 13-inch size or a distinct 14-inch wheel and tire combination.

1983 Mazda RX-7 GS
The 1983 Mazda RX-7 GS uses the 185/70R13 radial size. That keeps tire selection centered on 13-inch wheel compatibility, with room to choose among blackwall, redline, or wide whitewall presentations depending on the look and use planned for the car.
The 1983 Mazda RX-7 GS w/aluminum wheels also uses the 185/70R13 radial size. Tire selection stays straightforward here, but confirming the actual wheel dimensions on the car is still worthwhile before comparing series, sidewall style, and rim-width suitability.
The 1983 Mazda RX-7 GSL uses 185/70R13 radials as its primary fitment. That gives the owner a broad range of 13-inch choices, from sport-oriented blackwall tires to more appearance-driven options that can support a restoration-minded presentation.
The 1983 Mazda RX-7 GSL w/aluminum wheels remains on the 185/70R13 radial size. The main decision is less about fitment than about tire character, including whether the car is being kept close to period style or prepared for regular road use.
The 1983 Mazda RX-7 Limited Edition uses the 195/60R14 radial size, making it the clear outlier in the lineup. Tire choice for this version starts with confirming the 14-inch wheel setup, then selecting a tire that matches the car's lower-profile fitment character.
The 1983 Mazda RX-7 S can use either 165R13 or 185/70R13, so this sub-model requires a closer look before ordering tires. The practical next step is checking the actual wheel and existing tire setup on the car, then choosing the size that matches that configuration.
The 1983 Mazda RX-7 S w/aluminum wheels can also appear with either 165R13 or 185/70R13 radial tires. Because both are 13-inch sizes with different sizing conventions, confirming the current wheel and tire combination is the best starting point before comparing 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 1983 Mazda RX-7?
A 1983 Mazda RX-7 can use three different primary tire sizes: 165R13, 185/70R13, and 195/60R14. The correct size depends on the exact sub-model and wheel package, with most GS and GSL versions using 185/70R13, the Limited Edition using 195/60R14, and certain S models using either 165R13 or 185/70R13.
The practical first step is matching the tire size to the car's actual wheel diameter and configuration. Since the RX-7 lineup includes both 13-inch and 14-inch fitments, and some S models can appear with more than one size, it is smart to inspect the wheels currently on the car before comparing brands, sidewall styles, or tire series.
What size rim does a 1983 Mazda RX-7 use?
The 1983 Mazda RX-7 uses either a 13-inch or 14-inch rim, depending on the sub-model and tire size. The 165R13 and 185/70R13 tire fitments are built around 13-inch wheels, while the 195/60R14 fitment uses a 14-inch wheel.
Rim diameter is the first thing to confirm because a 13-inch tire cannot be mounted on a 14-inch wheel, and the reverse is equally true. On a car that has changed hands over the years, the current wheel setup may not match the original sub-model configuration, so checking the wheel itself before selecting tires helps avoid a preventable fitment mistake.
Why does the 1983 Mazda RX-7 have more than one tire size?
The 1983 Mazda RX-7 has more than one tire size because tire fitment varies across the model range. Most versions stay with 13-inch radial sizes, but the Limited Edition uses a 14-inch setup, and certain S models can appear with either 165R13 or 185/70R13.
That means tire selection is tied to the exact version of the car and the wheels actually installed on it. A buyer should identify the sub-model, then confirm the current wheel diameter and existing tire markings before choosing a replacement, especially on cars that may have received wheel swaps, trim changes, or earlier restoration work.
Choosing the Right Tire
What should I consider when choosing a 1983 Mazda RX-7 tire?
Start with the correct primary size for the exact 1983 Mazda RX-7 sub-model, since this car uses 165R13, 185/70R13, or 195/60R14 depending on configuration. After size, the next factors are wheel diameter, radial construction, intended use, and the character of the tire series available in that fitment.
Appearance also matters because some 185/70R13 options are available in redline or wide whitewall, while other RX-7 sizes lean toward blackwall sport and touring styles. It helps to decide whether the car is being kept close to a period presentation, driven regularly on the road, or set up for a more performance-oriented feel within the correct size.
What sidewall styles are available for 1983 Mazda RX-7 tires?
Sidewall style depends on the tire size chosen for the 1983 Mazda RX-7. In 185/70R13, available sidewall treatments include blackwall, redline, and wide whitewall, while the available 165R13 and 195/60R14 products center on blackwall construction.
That makes 185/70R13 the most flexible size for owners who care about visual presentation as much as fitment. The right sidewall choice comes down to the look being pursued, but the decision should still begin with the correct RX-7 sub-model and wheel diameter rather than choosing a style first and trying to force the fitment afterward.
What brands offer tires for the 1983 Mazda RX-7?
Tires for the 1983 Mazda RX-7 are available from BFGoodrich, Avon, Dunlop, Michelin, and Vredestein, depending on the size. Brand availability is strongest in 185/70R13, while 165R13 and 195/60R14 have a narrower selection tied to those specific fitments.
Brand choice should be considered alongside tire series, sidewall style, and wheel compatibility rather than treated as the only decision. A buyer comparing RX-7 tires should first lock in the correct size, then look at whether the available product is aimed more at classic road use, period appearance, or a sportier 1980s-style presentation.
Restoration & Appearance
Which tire should I choose for a period-style 1983 Mazda RX-7?
A period-style 1983 Mazda RX-7 tire choice starts with the correct original fitment size for the exact sub-model, whether that is 165R13, 185/70R13, or 195/60R14. From there, the most appropriate direction usually comes from choosing a radial with proportions, sidewall treatment, and overall character that suit an early 1980s Japanese sports car.
For many owners, 185/70R13 offers the broadest visual range because it includes blackwall, redline, and wide whitewall options. If exact restoration accuracy matters beyond general period style, the safest path is to compare the car against marque references, period photography, and vehicle-specific documentation before settling on a particular sidewall treatment or tire series.
How does tire construction affect the appearance of a restored 1983 Mazda RX-7?
On the 1983 Mazda RX-7, construction is straightforward because the primary fitments are radial tires. Even so, radial tires can still vary noticeably in appearance through sidewall style, tread presentation, and overall visual character, especially when comparing blackwall sport-oriented designs with redline or wide whitewall alternatives in 185/70R13.
That means the restored look is shaped less by choosing between bias-ply and radial, and more by matching the tire's size and styling to the car's intended presentation. A Limited Edition on 195/60R14 carries a different visual attitude than an S or GS on 13-inch tires, so wheel diameter and profile should be part of the appearance decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1983 Mazda RX-7?
Yes. Modifications can change tire fitment on a 1983 Mazda RX-7 even when the tire size itself sounds correct. Aftermarket wheels, altered wheel width, different offset, suspension changes, or body clearance differences can all affect whether a 165R13, 185/70R13, or 195/60R14 setup remains appropriate on the car.
That is especially important on an RX-7 because the factory range already includes both 13-inch and 14-inch applications. Before choosing replacement tires, inspect the wheel diameter actually installed, check for steering and fender clearance at full lock and suspension travel, and make sure the car's current setup matches the size being considered.
What should I inspect before driving a 1983 Mazda RX-7 on new tires?
Before driving a 1983 Mazda RX-7 on new tires, inspect the wheels for damage, verify that the tire size matches the wheel diameter, and confirm that each tire is inflated properly for its intended use. It is also wise to check valve stems, look over the brake and suspension area, and make sure nothing rubs at steering lock.
A collector-era RX-7 may sit for long periods, so the rest of the chassis deserves attention as much as the tires do. A short test drive followed by a second inspection can reveal early clearance issues, air loss, or vibration, and it gives the owner a chance to confirm that the car feels stable on its selected tire setup.
How should tires on a collector 1983 Mazda RX-7 be maintained?
Tires on a collector 1983 Mazda RX-7 should be checked regularly for air pressure, tread wear, sidewall cracking, bulges, cuts, and signs of age-related deterioration. Even on a lightly used car, radial tires still need periodic inspection because long storage periods can hide problems until the car returns to regular road use.
Storage conditions matter as well. Keeping the RX-7 away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, while moving the car occasionally can reduce long-term flat spotting. Any tire that shows persistent air loss, visible damage, or age-related weakness deserves closer evaluation before the car is driven at speed.
