1972 Mazda 808 Tires

The 1972 Mazda 808 uses two primary tire sizes: 155R13 in radial construction and 6.15-13 in bias-ply construction. Both sizes are associated with 13-inch rims, so the fitment question is less about wheel diameter and more about which construction and size format your particular car is set up to use.

That matters because a radial 155R13 and a bias-ply 6.15-13 are not the same kind of tire even though they share the same rim diameter. Before choosing, confirm what is currently on the car, inspect the wheel width, and consider whether you want a more traditional period-style setup or a radial tire in the correct 13-inch format.

The primary tire fitments for the 1972 Mazda 808 both use a 13-inch rim diameter. That applies to the radial 155R13 option as well as the 6.15-13 bias-ply option, making 13 inches the key wheel diameter for covered 808 configurations.

Rim diameter is only one part of the fitment picture, so it is still worth checking the actual wheel on the car before ordering tires. Width can matter just as much, especially on a vehicle that may have been changed over the years with replacement steel wheels, aftermarket wheels, or aluminum-wheel packages.

Yes. The covered 1972 Mazda 808 sub-models all share the same two tire-size choices: 155R13 radial and 6.15-13 bias-ply. That includes Sedan & Coupe, Sedan & Coupe w/aluminum wheels, Wagon, and Wagon w/aluminum wheels, so the fitment pattern stays consistent across those versions.

Even with shared fitment, the practical choice still depends on the car in front of you. A 808 that has remained close to a traditional setup may point you toward bias-ply, while one already using radial tires may be better evaluated around the 155R13 format and the wheel dimensions required by the tire you select.

6.15-13 is a bias-ply tire size for the 1972 Mazda 808. It uses the older numeric sizing format, where the first number describes nominal section width in inches and the 13 identifies the rim diameter, making it distinctly different from the 155R13 radial option.

That distinction affects both appearance and selection. Owners usually look at 6.15-13 when they want a more traditional tire presentation or want to keep the car aligned with period-style bias-ply fitment. Before changing away from it, confirm wheel dimensions and check clearances rather than assuming another construction behaves the same way.

155R13 is the radial tire size used on the 1972 Mazda 808. In this format, 155 is the nominal section width in millimeters, R indicates radial construction, and 13 is the wheel diameter, giving the car a more modern size convention than the numeric bias-ply alternative.

That makes 155R13 the right place to start if your 808 already has radial tires or if you want to stay with a classic radial format on a 13-inch wheel. Selection then becomes a matter of comparing available blackwall products, checking rim-width compatibility, and making sure the wheel and suspension setup still matches the intended tire.

Either can be appropriate for a 1972 Mazda 808 because both a 6.15-13 bias-ply and a 155R13 radial are primary fitment choices. The better direction depends on whether your priority is a traditional tire presentation or retaining a radial setup already matched to the car’s current wheels and use.

Construction choice should be made deliberately, not casually. A collector car kept close to period style may suit bias-ply, while a 808 already using radial tires may be easier to keep in that format. Wheel width, suspension condition, and tire-to-body clearance should all be checked before changing construction on an older vehicle.

Start with the basics: correct 13-inch rim diameter, radial construction, and the actual wheel width on the car. For the 1972 Mazda 808, available 155R13 options also vary by tire series and brand, with Michelin and Dunlop both offering blackwall tires in this size.

Once the fitment basics are confirmed, the decision becomes more about character and compatibility than about size alone. Compare the tire series, check the rim-width specification where it is given, and think about whether the car is being kept in a period-style road setup or simply needs a proper radial in the correct format.

The available 155R13 radial products for the 1972 Mazda 808 are offered in blackwall form. That gives the buyer a straightforward sidewall presentation in the currently available radial assortment rather than a wide range of appearance treatments.

Because sidewall variety is limited in the visible 155R13 selection, the more useful comparisons are brand, tire series, and wheel compatibility. If appearance is especially important on a restoration-oriented car, sidewall treatment should be considered alongside construction choice, since a bias-ply path may create a different overall visual impression.

Michelin and Dunlop both offer 155R13 radial tires for the 1972 Mazda 808. In the available assortment, Michelin appears through the XAS-FF series and Dunlop through the SP Sport Aquajet series, giving buyers two established period-style radial names to compare in the same basic size category.

Brand alone should not drive the decision. It is smarter to compare the exact tire series, confirm the tire matches your wheel dimensions, and decide whether the car is better served by staying with a radial 155R13 or by moving back toward the traditional 6.15-13 bias-ply format for appearance reasons.

For a period-style 1972 Mazda 808, the decision usually starts with construction. The 6.15-13 bias-ply size gives the car a more traditional presentation, while 155R13 keeps it in a classic radial format that still suits the era but presents the car differently.

Appearance goals should be matched to the kind of restoration being pursued. A driver-focused car may stay with radial construction, while a more preservation-minded build may lean toward bias-ply. When exact originality matters, compare your car against marque references, period photos, and vehicle-specific historical documentation before settling on one direction.

Tire construction changes more than road feel on a restored 1972 Mazda 808; it also changes the car’s visual character. A 6.15-13 bias-ply gives a more traditional vintage presentation, while a 155R13 radial introduces a later-style sizing format and the look associated with radial construction.

That is why restoration buyers should treat tire choice as part of the finished car’s overall stance and personality. The wheel design, ride height, and intended use all influence how the tire looks once mounted, so construction should be chosen with the completed car in mind rather than as a last-minute detail.

Yes. Even though the 1972 Mazda 808 uses 13-inch tire fitments, modifications can still change what works on the car. Aftermarket wheels, different wheel widths, suspension changes, or body alterations can all affect whether a given 155R13 radial or 6.15-13 bias-ply setup remains appropriate.

That is especially important on an older Japanese collector car that may have changed hands several times. A quick inspection of wheel diameter, wheel width, inner and outer clearance, and steering movement can prevent an expensive mistake. Tire selection should follow the car’s actual current configuration, not assumptions about how it left the factory.

Before driving a 1972 Mazda 808 on new tires, inspect the wheels for correct diameter and general condition, confirm the tires are seated properly, and verify there is no interference at full steering lock. It is also worth checking for suspension wear, uneven stance, or any issue that could affect tire clearance.

A collector car that has been parked for long periods deserves extra attention. Look over the valve stems, recheck pressure after initial use, and make sure the car tracks cleanly without rubbing or vibration. A short local drive followed by another inspection is a sensible way to confirm everything is working as intended.

Tires on a collector 1972 Mazda 808 should be checked regularly for pressure, cracking, cuts, bulges, uneven wear, and slow air loss. Low-mileage cars are easy to overlook, but age and storage conditions can matter just as much as tread depth on a vintage vehicle that sees occasional use.

Storage habits make a difference too. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and periodic movement can reduce flat-spotting on a vehicle that sits for extended periods. Before any longer drive, inspect the tires again rather than assuming they are road-ready because the car is rarely used.
