Mazda 808 Tires

Mazda 808 uses two listed tire sizes across the 1972 through 1977 model years: 155R13 and 6.15-13. The 155R13 size is a radial fitment for a 13-inch rim, and the 6.15-13 size is an older numeric bias-ply size that also fits a 13-inch rim. In the current product range, the available products are tied to the 155R13 family, including 155HR13 radial equivalents from Michelin and Dunlop.

The practical difference is not just the code on the sidewall but the type of tire the car is set up to use. A Mazda 808 restored for period driving feel may lean toward the numeric bias-ply route, while a car intended for more regular road use may be better aligned with the radial-size setup. Check the size on the existing tires, confirm the wheel diameter, and decide whether authenticity or modern road manners is your priority before making the final choice.

On a Mazda 808, 6.15-13 is a numeric bias-ply tire size. The 6.15 refers to the nominal section width in inches, and the 13 identifies the rim diameter in inches. Unlike a modern metric radial code, it does not include an aspect ratio or radial construction marker, so it reflects an earlier sizing convention rather than a later radial format.

That matters because a Mazda 808 wearing 6.15-13 tires is usually being kept closer to an older-style fitment than one on 155R13 radials. Numeric bias-ply tires also behave differently on the road, with a different steering feel and ride character than radials. If your car currently has numeric tires or wheels suited to that setup, stay with that type unless you have confirmed that a radial conversion is appropriate for the wheel and the car’s intended use.

On a Mazda 808, 155R13 is a metric radial tire size for a 13-inch wheel. The 155 is the nominal section width in millimeters, the R indicates radial construction, and the 13 is the rim diameter in inches. The currently listed products in this fitment appear as 155HR13 or 155R13 radial variants, both of which remain part of the same basic 155-width, 13-inch radial family.

For a buyer, the key point is that this is the more modern of the two Mazda 808 size conventions listed for 1972-1977. If the car already carries radial tires, 155R13 is usually the place to start your fitment check. Confirm wheel diameter and wheel width, then compare the car’s existing setup against the product specifications so you stay within the intended range for the wheel.

Mazda 808 does not have one universal tube answer because two tire types are listed for the same years. The 6.15-13 numeric bias-ply size requires a tube, while the listed 155R13 radial products are tubeless-type radial tires. The correct answer depends on which size system and construction your specific Mazda 808 is using.

That means tube choice should follow tire construction, not just model year. If your Mazda 808 is being fitted with a numeric bias-ply tire, plan on tube use as part of the installation. If it is using the radial 155R13 family on appropriate wheels, tube use is not part of the listed radial setup. Check the actual wheel, valve opening, and current tire type before changing from one system to the other.

A 1972 Mazda 808 can use either 155R13 or 6.15-13, so the model year alone is not enough to settle the fitment. Both are listed for 1972, and both use a 13-inch rim, but one is a radial metric size and the other is a numeric bias-ply size. The current tire on the car, the wheel type, and the restoration goal are the deciding factors.

Start by reading the size on the tire currently mounted to the car and confirming the wheel diameter directly. Then decide whether you are preserving a period-style bias-ply setup or maintaining a radial-equipped configuration. If the car has been changed over at some point in its life, old paperwork, prior restoration records, and marque knowledge can help you separate original-style practice from later substitutions.

The currently listed Mazda 808 tire products come from Michelin and Dunlop. Michelin is represented by the XAS-FF series in 155HR13 form, while Dunlop is represented by the SP Sport Aquajet in 155R13 or 155HR13 family sizing. Both are blackwall radial offerings for the 13-inch radial fitment associated with Mazda 808.

Brand choice matters most after size and construction have been settled. Once you know your Mazda 808 should be on the 155R13 radial family rather than the 6.15-13 numeric bias-ply route, you can compare brand character, sidewall appearance, and period flavor within that radial category. If your goal is authenticity to a certain era of road feel, the tire series can matter almost as much as the size itself.

The listed Mazda 808 radial products include Michelin XAS-FF and Dunlop SP Sport Aquajet series. Both sit in the 155R13 radial family and both use blackwall styling on 13-inch rims, but they represent different brand-specific tread and design approaches within period radial technology. They are not different wheel diameters or separate model-year fitments; they are alternative series choices within the same general radial size range.

For an owner, that means series selection becomes a secondary choice after confirming the car belongs on the radial setup at all. If your Mazda 808 is staying with 155R13-family tires, series differences may influence appearance, road feel, and how closely the tire matches a certain period presentation. Compare the car’s intended use—touring, local driving, or show presentation—before deciding which series best suits the project.

A Mazda 808 should be stored clean, dry, and out of direct sunlight, with the tires kept away from ozone sources such as electric motors, battery chargers, and welding equipment. Tire pressure should be maintained at the appropriate operating level for the tire in use, and the car should sit on a clean surface rather than bare earth. Long periods of motionless storage can create flat spotting, especially on older-style constructions.

If the Mazda 808 will be parked for an extended period, move it slightly from time to time or support it in a way that reduces continuous loading on one contact patch. A collector car that alternates between storage and occasional driving tends to preserve its tires better than one left untouched for months at a stretch. Consistent storage conditions are especially important when preserving original-style appearance and sidewall finish.

Tires on a Mazda 808 should be inspected before each drive and more thoroughly at regular service intervals, even if the car covers very few miles. Look for cracking, sidewall weathering, tread separation, impact damage, irregular wear, and air loss. Collector cars can age their tires by time and storage conditions rather than mileage, so visual condition matters as much as tread depth.

A good inspection routine also helps catch mismatched equipment before it becomes a road problem. If your Mazda 808 uses radial tires, check for even wear and stable inflation. If it uses a numeric bias-ply setup, pay close attention to tube-related air retention and sidewall condition. Periodic checks by a shop familiar with vintage tires can be especially helpful when the car is driven only occasionally and issues develop slowly.

Tires on a Mazda 808 should be replaced when age, cracking, hardening, bulges, separation, or repeated air loss indicate structural decline, even if the tread still looks usable. Collector-car tires often age out before they wear out. The decision should be made on condition, service history, and inspection results rather than tread depth alone, especially on a low-mileage car that spends long periods in storage.

That is particularly important on a Mazda 808 because a car that appears lightly used may still be riding on very old rubber. If the tire’s age is uncertain, treat it cautiously and have it evaluated before regular road use. Replacement is the prudent step whenever condition raises doubt, since preserved appearance does not guarantee preserved structure on an older collector-car tire.

Mazda 808 is associated here with two size conventions across 1972 through 1977: 155R13 and 6.15-13. That tells you the model sits in a period where both a metric radial fitment and an older numeric size are relevant to the car. The currently listed products are in the 155R13 radial family, while the size range itself also includes the numeric 6.15-13 option.

For a restoration, the original-style answer depends on the specific car, its market configuration, and how it was equipped when new. A restorer concerned with strict authenticity should compare the car against factory literature, surviving originals, and marque-club knowledge rather than relying on model-year alone. The listed sizes establish the correct fitment families, but the most accurate restoration decision comes from the individual car’s history and equipment.

Correct tire fitment can affect both the presentation and judged credibility of a Mazda 808, especially when the car is restored to factory-era appearance. Judges and informed buyers often notice whether the tire size, construction type, and sidewall style suit the period of the car. A radial-equipped Mazda 808 and a bias-ply-style Mazda 808 can project very different restoration intentions even when both use 13-inch wheels.

The practical takeaway is to decide early whether the car is being restored for authenticity, regular touring, or a blend of the two. A restoration aimed at marque judging should be checked against period references and club standards before final tire selection. Even on a modest and practical classic like the Mazda 808, details such as tire type and sidewall appearance can change how complete and convincing the finished car feels.

The listed Mazda 808 products are blackwall tires. That makes blackwall the available sidewall style within the current 155R13 radial offerings, and it suits the clean, understated appearance expected on many 1970s compact sedans. No alternate sidewall style is shown in the listed products for this model group.

For a restoration, that means blackwall is the logical starting point if you are using one of the available radial products. If the goal is to keep the Mazda 808 visually consistent with its era, blackwall presentation aligns well with the practical character of the car. Owners pursuing highly exact show standards should still compare surviving photos, factory literature, and marque references for the specific body and market configuration they are restoring.

A Mazda 808 can be driven on public roads when the tires are the correct size, in sound condition, properly installed, and appropriate to the wheel setup. The listed radial products for 155R13 are intended for normal road use on a 13-inch rim, while a 6.15-13 bias-ply setup brings a different driving character and should be treated with period-correct expectations. Safety depends on condition and fitment, not simply on whether the size appears on the car.

Before regular driving, confirm the tires are not aged out, damaged, or mismatched side to side. A Mazda 808 on radial tires will generally feel more familiar to a modern driver than one on bias-ply tires, but either setup still needs careful pressure management and suspension health. Good road manners start with a complete system check rather than tire selection in isolation.

Before driving a Mazda 808, check tire pressure, visible sidewall condition, tread condition, valve stems, wheel security, and any signs of age cracking or separation. Confirm that all four tires match in size family and construction type, since the model can appear with either radial 155R13 or numeric 6.15-13 fitments. A quick walk-around catches many of the problems that matter most on a lightly used collector car.

It also pays to look beyond the tire itself. Steering, brakes, wheel bearings, and alignment all influence how safely the Mazda 808 will use its tires on the road. If the car has been off the road for a long time, treat the first drive as a recommissioning exercise rather than a casual outing. A thorough pre-drive check is especially worthwhile when an older compact car still wears an uncommon or vintage-style tire setup.

A Mazda 808 should be driven at speeds appropriate to the tire construction, condition, and the overall mechanical state of the car. A healthy radial-equipped 155R13 setup will generally suit ordinary collector-car road use better than an older-style 6.15-13 bias-ply arrangement, which calls for more modest expectations in steering response and sustained-speed comfort. Tire age and condition matter as much as the size itself when judging appropriate speed.

The safest approach is to treat the car conservatively until you know how it behaves on the fitted tires. Start with shorter drives, reassess pressure and temperature afterward, and avoid asking an older or bias-ply-equipped Mazda 808 to perform like a modern car. Even with the correct fitment, sensible speed is the one that matches the tire’s condition, the road surface, and the car’s overall preparedness.
