The 1974 Mazda 808 came from an era when compact imports were gaining real traction in the U.S., offering tidy dimensions, efficient engineering, and a more European-flavored road feel than many domestic small cars. For owners restoring or maintaining one today, tire choice plays a big role in preserving that character. The 1974 Mazda 808 uses two primary 13-inch fitment paths: a 155R13 radial and a 6.15-13 bias-ply. That gives buyers a meaningful choice between a more modern radial presentation and a more traditional period-style bias-ply look. The right decision depends on the car's wheels, the appearance you want, and how closely you want to stay to the original driving feel.
Which Tire Size Is Right for The 1974 Mazda 808
The 1974 Mazda 808 uses two primary tire sizes, and both fitment paths share the same 13-inch rim diameter. The main decision is not wheel diameter but construction, since the car can be fitted with either a 155R13 radial or a 6.15-13 bias-ply across the covered sub-models. Choosing between them comes down to the type of driving, the look you want, and whether the car is being kept in a more restoration-oriented configuration.
Fit(s): Sedan & Coupe, Sedan & Coupe w/aluminum wheels, Wagon, and Wagon w/aluminum wheels
Construction: Radial|Rim: 13 in
155R13 is a Euro-metric radial size in which 155 refers to nominal section width in millimeters, R indicates radial construction, and 13 is the wheel diameter in inches. On a 1974 Mazda 808, this size represents the radial fitment path and suits owners who want a more modern tire construction while staying within the vehicle's correct 13-inch format. Available choices include Michelin and Dunlop offerings in blackwall form, with series such as Michelin XAS-FF and SP Sport Aquajet. This size is worth considering when road use, radial construction, and a traditional imported-car appearance all matter.
Fit(s): Sedan & Coupe, Sedan & Coupe w/aluminum wheels, Wagon, and Wagon w/aluminum wheels
Construction: Bias Ply|Rim: 13 in
6.15-13 is a numeric bias-ply size where 6.15 indicates nominal section width in inches and 13 identifies the wheel diameter. For the 1974 Mazda 808, it represents the vintage bias-ply fitment route and is most relevant for owners aiming to retain an earlier tire construction and a more period-style look. Bias-ply construction changes both the visual character and the way the car feels on the road compared with a radial. This size deserves a close look when restoration priorities, wheel originality, and traditional presentation carry more weight than moving to radial construction.
Tire fitment stays straightforward across the covered 1974 Mazda 808 sub-models because each one uses the same two primary 13-inch tire-size choices. Checking the exact sub-model still helps confirm the wheel setup before choosing between the radial and bias-ply fitment paths.

1974 Mazda 808 Sedan & Coupe
The 1974 Mazda 808 Sedan & Coupe uses the same two primary tire choices found across the model line: 155R13 radial and 6.15-13 bias-ply. That gives owners room to choose between a more modern radial construction and a more traditional period-style bias-ply presentation on a 13-inch wheel.
The 1974 Mazda 808 Sedan & Coupe w/aluminum wheels follows the same tire-size pattern, with both 155R13 radial and 6.15-13 bias-ply fitments available. The key step here is confirming the actual wheel dimensions before selecting a tire, especially if appearance and construction type are both part of the decision.
The 1974 Mazda 808 Wagon shares the same dual fitment approach, using either 155R13 radial or 6.15-13 bias-ply tires. That keeps tire selection focused on how the wagon will be used, whether the goal is a road-friendly radial setup or a more traditional bias-ply look.
The 1974 Mazda 808 Wagon w/aluminum wheels also uses 155R13 radial and 6.15-13 bias-ply tire sizes. Tire choice comes down to construction preference and wheel confirmation, particularly for owners trying to balance period-style appearance with practical road use.
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.
Best 1974 Mazda 808 Tires for Sale
Available 155R13 radial options for the 1974 Mazda 808 include Michelin and Dunlop blackwall tires in series such as Michelin XAS-FF and SP Sport Aquajet. These choices give buyers a useful comparison in brand, tire series, and rim-width compatibility within the correct 13-inch radial fitment.
Common 1974 Mazda 808 tire questions usually center on choosing between 155R13 radial and 6.15-13 bias-ply fitments, understanding 13-inch wheel requirements, and sorting through radial product options for road use, appearance, and restoration goals.
Tire Size & Fitment
What tire size fits a 1974 Mazda 808?
The 1974 Mazda 808 uses two primary tire sizes: 155R13 in radial construction and 6.15-13 in bias-ply construction. Both sizes apply across the covered Sedan & Coupe, Sedan & Coupe w/aluminum wheels, Wagon, and Wagon w/aluminum wheels configurations, so the basic fitment pattern stays consistent throughout the model range.
That means the main choice is construction rather than chasing a different wheel diameter for different sub-models. Owners should still confirm the actual wheels on the car, especially after decades of use or modification, then decide whether a radial or bias-ply tire better matches the car's intended appearance, driving use, and overall setup.
What size rim does a 1974 Mazda 808 use?
The 1974 Mazda 808 uses a 13-inch rim diameter with both of its primary tire sizes. The 155R13 radial and the 6.15-13 bias-ply both correspond to the same 13-inch wheel diameter, which keeps the basic wheel-size question relatively simple compared with vehicles that changed rim size by trim level.
Rim diameter is only one part of fitment, so it is worth checking the wheel width and the actual wheel currently on the car before ordering tires. That matters even more if the Mazda has aluminum wheels, replacement wheels, or older service parts, since the correct 13-inch diameter alone does not answer every clearance and compatibility question.
Do all 1974 Mazda 808 sub-models use the same tire size?
Yes. The covered 1974 Mazda 808 sub-models all share the same two primary 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 there is no separate tire-size split among those configurations.
Since the size options stay the same, sub-model identification mainly helps confirm the wheel setup rather than leading to a different size chart. The practical decision is choosing which construction better suits the car, then checking the wheels themselves to make sure the selected tire works with the current rim width and overall vehicle condition.
Bias-Ply & Radial Options
Is 6.15-13 a bias-ply or radial tire for the 1974 Mazda 808?
On the 1974 Mazda 808, 6.15-13 is a bias-ply tire size. It uses the older numeric bias-ply sizing format, where the leading number refers to nominal section width in inches and the 13 identifies the wheel diameter. That makes it the traditional-construction alternative to the car's 155R13 radial fitment.
Choosing 6.15-13 usually points toward a more period-style look and an older tire construction feel. Before selecting it, confirm that the car still has a wheel setup suited to that fitment and think through whether the goal is restoration-oriented presentation, occasional collector use, or more regular driving where a radial might be the preferred direction.
Should I use bias-ply or radial tires on a 1974 Mazda 808?
A 1974 Mazda 808 can be fitted with either a 155R13 radial or a 6.15-13 bias-ply, so the right choice depends on what matters most for the car. The radial route follows a more modern construction, while the bias-ply route keeps a more traditional vintage tire format and appearance on the same 13-inch wheel diameter.
Owners focused on period-style presentation often lean toward bias-ply, while owners planning more road use often consider the radial path first. The best next step is to confirm the wheels on the car, then choose the construction that matches its use, visual goals, and the kind of driving character you want to preserve.
What should I check before converting my 1974 Mazda 808 from bias-ply to radial tires?
A conversion from 6.15-13 bias-ply to 155R13 radial starts with confirming that the car's wheels are the correct 13-inch diameter and suitable for the radial tire's rim-width requirements. It is also important to inspect the overall wheel condition and make sure the rest of the car's tire fitment space has not been altered by suspension or body changes.
Radial conversion should be approached as a fitment decision, not as an automatic interchange. Check steering and fender clearance, look at the suspension condition, and verify that all four tires will match in size and construction. On an older Mazda 808, that careful review matters just as much as the tire size itself.
Choosing the Right Tire
What should I consider when choosing a 155R13 tire for a 1974 Mazda 808?
Start with the basics: the 155R13 tire needs to match the Mazda's 13-inch wheel diameter and work with the wheel width actually on the car. For this size, available radial options include blackwall tires from Michelin and Dunlop, so the decision can include brand preference, tire series, and how closely the tire suits the character of the car.
Beyond the size itself, compare the tire's intended presentation and wheel compatibility. A buyer restoring a stock-looking compact may care about maintaining a traditional imported-car appearance, while another owner may focus more on practical road use. It also helps to confirm that the Mazda still wears its original-style wheels rather than later replacements.
What sidewall styles are available for 1974 Mazda 808 tires?
The available 155R13 radial products for the 1974 Mazda 808 use a blackwall sidewall style. That gives the car a clean, understated presentation that fits the compact imported look of the period without introducing whitewall or raised-letter styling that would shift the car's appearance in a different direction.
Sidewall style matters because it changes the overall look even when the size stays correct. For an owner trying to keep the Mazda visually restrained and era-appropriate in a broad sense, blackwall is the natural choice among the current 155R13 products. It should still be paired with the right construction and wheel setup for the car.
What brands offer tires for the 1974 Mazda 808?
In the 155R13 radial fitment, the 1974 Mazda 808 has product options from Michelin and Dunlop. Those choices appear in blackwall form and include tire series such as Michelin XAS-FF and SP Sport Aquajet, giving buyers more than one period-relevant radial path within the correct 13-inch size range.
Brand alone should not drive the entire decision. Compare the specific tire series, confirm wheel compatibility, and think about whether the car is being prepared for regular road use or a restoration-oriented presentation. The best choice is usually the one that aligns the correct size with the Mazda's wheel setup and the look you want.
Restoration & Appearance
Which tire should I choose for a period-style 1974 Mazda 808?
For a period-style 1974 Mazda 808, the first decision is whether to stay with the traditional 6.15-13 bias-ply format or use the 155R13 radial fitment that also applies to the car. Bias-ply usually speaks more directly to an older visual and driving presentation, while the radial route keeps the correct general size family with a more modern construction.
Appearance goals should be balanced against how the car will actually be driven. A display-focused or restoration-oriented Mazda may point toward bias-ply, while a road car may justify the radial path. When exact originality matters, it is wise to compare the tire decision against marque-specific restoration references and the car's actual wheel equipment.
How does tire construction affect the appearance of a restored 1974 Mazda 808?
Tire construction changes more than ride and handling on a restored 1974 Mazda 808; it also changes the car's visual character. A 6.15-13 bias-ply gives the car a more traditional vintage presentation, while a 155R13 radial tends to look more like a later road-use choice even though it remains a correct primary fitment path for the model.
That difference becomes noticeable on a compact car where tire shape and stance are easy to see. Owners trying to preserve a strong period impression often weigh construction almost as heavily as size. The best appearance result usually comes from matching the tire style to the wheel type, trim level, and overall restoration direction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1974 Mazda 808?
Yes. A 1974 Mazda 808 may have started with 13-inch fitment, but later wheel changes, altered suspension height, replacement fenders, or non-original aluminum wheels can all affect tire selection. Even when using the correct 155R13 radial or 6.15-13 bias-ply size, the actual car may no longer match its original wheel and clearance conditions.
That is why the tire choice should begin with a physical inspection rather than size alone. Check wheel diameter and width, look at steering and fender clearance, and make sure the car has even suspension height side to side. Small older cars can be especially sensitive to wheel changes that seem minor at first glance.
What should I inspect before driving a 1974 Mazda 808 on new tires?
Before road use, inspect the wheels for damage or corrosion, confirm the tire beads are seated properly, and verify that all four tires match the intended size and construction. It also helps to look over the suspension, steering components, and alignment condition, since a new set of tires cannot compensate for worn hardware on an older 1974 Mazda 808.
A short low-speed test drive is a smart next step after installation. Listen for rubbing, watch for pull or vibration, and recheck inflation after the first drive cycle. On a collector-era compact, simple issues like aged valve stems, old wheel hardware, or uneven ride height can affect how well a new tire setup works.
How should 155R13 or 6.15-13 tires on a collector 1974 Mazda 808 be maintained?
Collector-car tire care starts with regular pressure checks and visual inspection, whether the 1974 Mazda 808 is running 155R13 radials or 6.15-13 bias-ply tires. Look for cracking, cuts, bulges, irregular wear, and signs of air loss. Cars that are driven infrequently should not be ignored simply because the tread still looks good.
Storage conditions matter almost as much as mileage on an older Mazda. Keep the car away from prolonged sunlight, excess heat, moisture, and ozone sources, and inspect the tires before every meaningful drive. A vehicle that sits for long periods should also have its tires checked for flat spotting and age-related condition changes.
