The 1991 Mazda MX-6 sits in an interesting spot among early-1990s sport coupes, blending front-wheel-drive practicality with a sleeker, more driver-focused feel than many mainstream two-doors of the period. Buyers looking after one today often want tires that respect that balance between everyday road manners and era-appropriate appearance. Tire fitment on the 1991 Mazda MX-6 is fully radial, with 185/70R14, 195/60R15, and 205/60R15 sizes used depending on sub-model. That opens the door to different sidewall looks, brand choices, and touring or performance-minded tire series. The key is confirming the exact trim and wheel diameter before choosing a tire that matches the car's intended use and presentation.
Which Tire Size Is Right for The 1991 Mazda MX-6
Three primary tire sizes apply to the 1991 Mazda MX-6, and the right one depends on the exact sub-model and wheel diameter. DX, LE, and LX models use a 14-inch setup, while GT models use 15-inch tires in two different widths. Before comparing brands or sidewall styles, confirm whether the car is a DX, GT, LE, or LX and verify the wheel diameter actually on the vehicle, especially if it has been changed over the years.
In 185/70R14, the 185 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 14 is the wheel diameter in inches. This size is used on 14-inch-wheel MX-6 sub-models and keeps the fitment in a conventional modern metric radial format familiar to most buyers. Available choices include blackwall and wide whitewall designs from brands such as BFGoodrich, Avon, Dunlop, Michelin, and Vredestein across several distinct tire series. It is a useful size for owners balancing standard road use with a more customized or restoration-minded appearance choice.
A 195/60R15 tire uses a 195-millimeter nominal section width, a 60-series profile, radial construction, and a 15-inch rim. On the 1991 Mazda MX-6, this size applies to certain GT configurations, so it should not be treated as a universal fitment across the full model line. Product choices include blackwall, wide whitewall, redline, and raised white letter styles, with BFGoodrich and Michelin represented in the available selection. This size makes sense for buyers who have confirmed a 15-inch GT wheel setup and want to compare appearance-focused options alongside more conventional radial offerings.
The 205/60R15 format indicates a 205-millimeter nominal section width, a 60-series aspect ratio, radial construction, and a 15-inch wheel diameter. This is the wider of the two 15-inch MX-6 GT fitments, so wheel width and vehicle setup deserve close attention before settling on a tire. Available options include blackwall, wide whitewall, and raised white letter styles from Michelin, American Classic, Coker Classic, and BFGoodrich in several different series. It gives GT owners a broader visual range, from understated modern-looking tires to more traditional sidewall treatments.
Sub-model fitment matters on the 1991 Mazda MX-6 because tire size is not the same across the full range. DX, LE, and LX models share one 14-inch radial size, while GT models use 15-inch radial fitments, making trim and wheel confirmation the first step before choosing tires.

1991 Mazda MX-6 DX
The 1991 Mazda MX-6 DX uses a 14-inch radial tire setup centered on 185/70R14. That keeps tire selection focused on choosing the right blackwall or whitewall presentation and comparing touring-oriented product lines rather than sorting through multiple fitment sizes.
The 1991 Mazda MX-6 GT uses 15-inch radial tire fitments, with both 195/60R15 and 205/60R15 associated with the model. Tire selection starts with confirming which wheel setup is on the car, then comparing sidewall style, series, and rim-width suitability within the correct size.
The 1991 Mazda MX-6 LE shares the 185/70R14 radial fitment used on the 14-inch-wheel cars. Once that size is confirmed, the decision usually comes down to whether the car calls for a straightforward blackwall look or a more distinctive whitewall treatment.
The 1991 Mazda MX-6 LX also uses 185/70R14 radial tires on a 14-inch rim. That makes tire buying more straightforward, with the main choices centered on brand, tire series, and whether the car is being kept closer to a stock-looking road setup or given a more customized appearance.
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 MX-6?
The 1991 Mazda MX-6 uses three tire sizes depending on sub-model: 185/70R14, 195/60R15, and 205/60R15. DX, LE, and LX models use 185/70R14, while GT models use 15-inch tire fitments in 195/60R15 or 205/60R15.
The practical step is to identify the exact trim and confirm the wheel diameter currently on the car. A 14-inch tire will not mount on a 15-inch wheel, and a GT should not be assumed to use the same tire size as a DX, LE, or LX without checking the actual setup first.
What size rim does a 1991 Mazda MX-6 use?
The 1991 Mazda MX-6 uses either a 14-inch or 15-inch rim, depending on sub-model and tire size. The 185/70R14 fitment uses a 14-inch wheel, while 195/60R15 and 205/60R15 fitments use 15-inch wheels.
Rim diameter should be verified before looking at tire styles or brands, because tire size must match the wheel exactly. On an older MX-6, it is also smart to confirm whether the car still has its original wheel setup or has been changed to a different diameter at some point in its life.
Why does the 1991 Mazda MX-6 have more than one tire size?
The 1991 Mazda MX-6 has more than one tire size because fitment varies by sub-model. DX, LE, and LX models share 185/70R14, while GT models use 15-inch sizes, including 195/60R15 and 205/60R15.
That means tire selection is tied to the specific version of the car rather than the model name alone. It also means a buyer should not rely only on appearance, since both 15-inch GT sizes are close in profile but still need to be matched to the actual wheel and vehicle setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 1991 Mazda MX-6?
Start with the correct size for the exact MX-6 sub-model and wheel diameter, then compare the tire's construction, rim-width range, sidewall style, and overall character. Since all primary fitments for the 1991 Mazda MX-6 are radial, the decision is more about selecting the right radial in the right size than choosing between basic construction types.
After fitment is confirmed, think about how the car will be used and presented. A blackwall tire gives a more understated modern look, while whitewall, redline, or raised white letter options change the appearance significantly. Brand and series differences also matter when matching the tire to a touring-oriented or sportier period-style presentation.
What sidewall styles are available for 1991 Mazda MX-6 tires?
Available sidewall styles for the 1991 Mazda MX-6 include blackwall, wide whitewall, redline, and RWL, which is raised white letter. The exact sidewall choices depend on the tire size, with the broadest visual variety appearing in the 15-inch GT fitments.
Sidewall style affects appearance much more than fitment, so the first priority is still getting the correct size for the sub-model and wheel. Once that is settled, the choice becomes a matter of whether the car should retain a restrained factory-era look, a customized presentation, or a more performance-themed visual style.
What brands offer tires for the 1991 Mazda MX-6?
Brands available for 1991 Mazda MX-6 tire sizes include BFGoodrich, Michelin, Avon, Dunlop, Vredestein, American Classic, and Coker Classic. Brand availability varies by size, so the exact selection depends on whether the car uses 185/70R14, 195/60R15, or 205/60R15.
That variety gives buyers room to compare visual style, tire series, and rim-width compatibility within the proper fitment. The most useful approach is to narrow the search by size first, then compare brands within that size instead of trying to choose a brand before confirming which tire dimensions belong on the car.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Mazda MX-6?
A period-style 1991 Mazda MX-6 tire choice starts with the correct original fitment family for the specific sub-model: 185/70R14 for DX, LE, and LX, or a 15-inch radial size for GT. From there, the best match depends on whether the goal is a restrained blackwall look or a more distinctive whitewall, redline, or raised white letter presentation.
For a restoration-oriented car, the safest approach is to preserve the proper size and wheel diameter before focusing on appearance details. When exact originality matters, vehicle-specific photos, brochures, club knowledge, and restoration references can help narrow down which visual treatment best suits the car's era and intended presentation.
How does tire construction affect the appearance of a restored 1991 Mazda MX-6?
On the 1991 Mazda MX-6, primary fitment is already radial, so the appearance question is less about switching from bias-ply to radial and more about choosing the right radial style. Blackwall tires give the cleanest contemporary look, while whitewall, redline, and raised white letter versions push the car toward different period-inspired visual directions.
A restored MX-6 can look noticeably different depending on sidewall treatment even when the size remains correct. Keeping the proper dimensions for the sub-model helps preserve stance and proportion, while the sidewall design lets the owner decide whether the finished car leans closer to stock, sporty, or customized late-1980s and early-1990s style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Mazda MX-6?
Yes, modifications can affect tire fitment on a 1991 Mazda MX-6 even when the tire size looks close to stock. Aftermarket wheels, changes in wheel width, suspension lowering, and body or fender alterations can all change the clearance available for 185/70R14, 195/60R15, or 205/60R15 tires.
A modified MX-6 should be checked for wheel diameter, wheel width, steering clearance, and room under compression before a tire is chosen. That matters especially on GT models using 15-inch tires, where two different widths are already part of the fitment picture and small setup changes can affect the result.
What should I inspect before driving a 1991 Mazda MX-6 on new tires?
Before driving a 1991 Mazda MX-6 on new tires, inspect the wheels for correct diameter and condition, confirm the tire size matches the sub-model, and check that the tires are mounted and inflated properly. It is also wise to look at the suspension, steering components, and alignment if the car has been sitting or has uneven tire wear history.
A short clearance check is worthwhile before regular driving, especially at full steering lock and over suspension movement. Older coupes can also have issues unrelated to the tire itself, such as worn bushings or bent wheels, so a careful inspection helps the new tires perform as intended instead of masking other problems.
How often should tires on a 1991 Mazda MX-6 be inspected?
Tires on a 1991 Mazda MX-6 should be inspected regularly, not just when tread looks low. A collector or low-use car deserves frequent visual checks for cracking, bulges, cuts, uneven wear, and slow air loss, while a regularly driven MX-6 should be looked over as part of routine maintenance.
Inspection matters because age and storage conditions can affect a lightly used tire long before it appears worn out. Checking pressure, sidewall condition, and tread surface before longer drives is especially important on a car that may spend stretches parked, since time and environment can be just as important as mileage.
