1975 Mazda 808 Tires

The 1975 Mazda 808 uses two primary tire sizes: 155R13 in radial construction and 6.15-13 in bias-ply construction. Both sizes are tied to a 13-inch rim, so the main difference is not wheel diameter but the tire sizing system and construction type you want to keep on the car.

That means the real fitment decision starts with how the car is currently equipped and what kind of tire character you want. A restoration-minded owner may prefer the period-style look of a 6.15-13 bias-ply, while a driver focused on a radial setup may look at 155R13 options. Wheel width and overall clearance should still be confirmed before making a final selection.

The tire fitments used on the 1975 Mazda 808 are built around a 13-inch rim diameter. Both the 155R13 radial size and the 6.15-13 bias-ply size share that same 13-inch wheel diameter, which helps narrow the search quickly when replacing tires on a stock-style setup.

Rim diameter is only part of the fitment picture, especially on older cars that may have changed wheels over time. The safest next step is to confirm the actual wheel diameter stamped on the rim and compare wheel width against the tire being considered. That is especially useful if the car has aluminum wheels or any aftermarket wheel history.

Yes. The covered 1975 Mazda 808 Sedan & Coupe, Sedan & Coupe w/aluminum wheels, Wagon, and Wagon w/aluminum wheels all use the same two primary tire sizes: 155R13 radial and 6.15-13 bias-ply. The sub-model does not introduce a separate tire size within this fitment range.

That consistency simplifies the search, but it does not remove the need to inspect the actual wheel and tire setup on the car. A 155R13 radial and a 6.15-13 bias-ply create different ownership choices even though they share the same rim diameter. Owners should verify whether the goal is period-style restoration, regular driving, or preserving an existing wheel-and-tire combination.

Start with the correct 13-inch fitment, then look at construction, rim-width compatibility, brand, and the intended role of the car. On the 1975 Mazda 808, 155R13 is the radial size, and available choices include blackwall tires from Michelin and Dunlop in distinct tire series aimed at vintage-compatible use.

The best comparison points are whether the wheel width falls within the tire's accepted range, whether you want a more European period-style radial character, and how closely the tire suits the car's use. A lightly driven collector car may be chosen differently than a car that sees regular road miles. Matching the tire to both the wheel and the car's purpose matters more than choosing by name alone.

The available 155R13 radial products for the 1975 Mazda 808 are offered in blackwall form. That gives the car a clean, understated presentation that suits many compact cars from the mid-1970s without pushing the look toward a more aggressive muscle-car style or a heavy whitewall treatment.

Sidewall appearance should still be chosen with the overall build in mind. A blackwall tire tends to work well on a stock-looking driver or a restrained restoration, but the final visual result also depends on wheel finish, ride height, and the car's overall condition. Owners trying to preserve a particular period look should compare the tire's sidewall treatment with the rest of the vehicle rather than treating size alone as the whole decision.

The current 155R13 radial options for the 1975 Mazda 808 include Michelin and Dunlop. Within that size, Michelin appears in the XAS-FF series and Dunlop appears in the SP Sport Aquajet series, giving owners a choice between two established vintage-oriented radial offerings in the correct 13-inch category.

Brand matters most when it helps you narrow the kind of tire presentation and specification you want, not when it becomes a shortcut around fitment. The smarter comparison is still size, rim compatibility, sidewall style, and the tire series itself. Once those points line up with the Mazda's wheel setup and intended use, brand becomes part of a broader selection process instead of the only deciding factor.

A period-style 1975 Mazda 808 can be approached from two directions. The 6.15-13 bias-ply size preserves the more traditional construction and visual character associated with older tire design, while a 155R13 radial keeps the car within a vintage-compatible 13-inch size but with a more modern radial format.

The right choice depends on whether appearance, driving feel, or long-term use matters most in the restoration. A bias-ply tire usually makes the strongest visual statement for a traditional presentation, while a radial may better suit a car that sees more road time. When exact originality matters, it is worth checking marque-specific historical references before settling on a brand or sidewall treatment.

Tire construction changes more than road feel on a restored 1975 Mazda 808; it also affects the car's visual attitude. A 6.15-13 bias-ply usually supports a more traditional vintage look, while a 155R13 radial gives the car a later, more modernized presentation even though both fit the same 13-inch rim diameter.

That difference becomes noticeable once the tire is mounted and viewed in relation to the wheel, ride height, and body lines. Owners chasing a faithful period impression often start by deciding whether the car should read as original in spirit or updated for regular use. Construction choice sets that tone early, so it is worth treating as an appearance decision as well as a fitment decision.

Yes. Modifications can change how either a 155R13 radial or a 6.15-13 bias-ply works on a 1975 Mazda 808, even though both are tied to a 13-inch rim. Wheel width, offset, suspension height, alignment changes, and body or brake modifications can all alter clearance and the way the tire sits in the wheel opening.

That is why an older Mazda should be checked as it exists today rather than assumed to match a stock configuration. A car with aftermarket wheels, replacement suspension parts, or ride-height changes may need closer measurement at the fender, steering, and inner wheelhouse. Looking at the complete wheel-and-tire package prevents surprises that a simple size comparison can miss.

Before putting a 1975 Mazda 808 back on the road with new tires, inspect the wheels for correct diameter and condition, confirm lug hardware seats properly, and check that the tires clear the fenders and suspension through a full steering sweep. Tire pressure should also be set properly, and valve stems should be in sound condition.

A brief road test should be preceded by a close look at wheel bearings, brakes, and any suspension wear that could affect how the tire tracks. Older collector cars often sit for long periods, so problems outside the tire itself can show up quickly once the car is moving again. Rechecking pressure and lug torque after the first drive is a sensible final step.

Tires on a collector 1975 Mazda 808 should be kept properly inflated, inspected regularly for cracks, bulges, cuts, uneven wear, and slow air loss, and protected from long periods of heat and direct sunlight. Even a lightly used car can age its tires over time, so visual condition matters just as much as tread depth.

Storage habits make a real difference on a vintage compact that may spend weeks or months parked. Clean, dry surroundings and occasional movement help reduce flat spotting and long-term stress on one section of the tire. It is also wise to inspect the spare, since older collector cars often retain a spare that looks fine at a glance but has aged well beyond safe road use.
