The 1970 Mazda 1200 came from a period when compact Japanese cars were earning a reputation for efficiency, simple mechanical design, and everyday practicality. Whether kept as a sedan, coupe, or station wagon, it is a light, straightforward car that benefits from staying close to its intended tire proportions. This Mazda 1200 uses either a 155R13 radial or a 6.15-13 bias-ply tire, both on 13-inch rims. That gives owners a clear choice between traditional bias-ply presentation and a radial fitment, with current options centered on blackwall tires. The right decision depends on the car's wheel setup, restoration direction, and how it will actually be driven.
Which Tire Size Is Right for The 1970 Mazda 1200
The 1970 Mazda 1200 uses two primary tire sizes, and both share the same 13-inch rim diameter. The main decision is not wheel diameter, but whether your car is staying with the traditional 6.15-13 bias-ply fitment or using the 155R13 radial size. Sedan, coupe, and station wagon versions can use either size, so the choice usually comes down to construction, appearance, and how the car is set up for road use.
155R13 is a Euro-metric radial size in which 155 identifies the nominal section width in millimeters, R indicates radial construction, and 13 identifies the rim diameter in inches. On a 1970 Mazda 1200, this size represents the radial-fitment path while keeping the correct 13-inch wheel diameter. Available choices include Michelin and Dunlop blackwall radials in series such as Michelin XAS-FF and SP Sport Aquajet. This size suits owners who want a radial tire in the proper vintage diameter class while still checking wheel width and overall vehicle clearance.
6.15-13 is a numeric bias-ply size in which 6.15 refers to the nominal section width in inches and 13 identifies the rim diameter. That format reflects the traditional sizing language used on many compact cars of this era and preserves the period-style bias-ply construction associated with older tire designs. On the 1970 Mazda 1200, it serves as the classic fitment choice for owners focused on vintage presentation and original-style tire behavior. Before choosing it, confirm that the car's wheels and overall setup still match a bias-ply oriented replacement plan.
Tire fitment is straightforward across the covered 1970 Mazda 1200 sub-models because the same two primary sizes appear throughout. Checking the exact body style still helps confirm whether you want to stay with the traditional bias-ply option or move to the radial size on the car's existing 13-inch wheels.

1970 Mazda 1200 Sedan & Coupe
The 1970 Mazda 1200 Sedan & Coupe can use either the 155R13 radial or the 6.15-13 bias-ply size. That gives owners a clear choice between a more traditional period-style bias-ply presentation and a radial setup that still stays within the correct 13-inch fitment family.
The 1970 Mazda 1200 Station Wagon uses the same tire-size choices as the sedan and coupe, with both 155R13 radial and 6.15-13 bias-ply fitments available. Tire selection comes down to preserving a vintage look, matching the wheel setup, and deciding which construction best fits the wagon's intended 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.

Tire Size & Fitment
What tire size fits a 1970 Mazda 1200?
The 1970 Mazda 1200 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 real fitment decision is construction type rather than wheel diameter.
That means the next step is confirming how the car is equipped and what kind of result you want. A restoration-oriented Mazda 1200 may stay with the 6.15-13 bias-ply size, while a driver-focused car may use the 155R13 radial. Wheel width, overall clearance, and any later wheel changes should still be checked before settling on either size.
What size rim does a 1970 Mazda 1200 use?
The 1970 Mazda 1200 uses a 13-inch rim diameter with both of its primary tire sizes. That is true whether the car is fitted with the 155R13 radial size or the 6.15-13 bias-ply size.
Rim diameter is only one part of the fitment picture, so it is worth confirming the wheel itself before choosing tires. A car that still has its original-style wheels may simply need the correct construction and size, while a Mazda 1200 with replacement wheels should also be checked for width and general compatibility with the tire you are considering.
Do all 1970 Mazda 1200 sub-models use the same tire size?
Yes. The 1970 Mazda 1200 Sedan & Coupe and the 1970 Mazda 1200 Station Wagon both use the same two primary tire-size choices: 155R13 radial and 6.15-13 bias-ply. There is no separate tire-size split between those covered sub-models.
That makes sub-model identification less about finding a different size and more about confirming the tire style that suits the car. Owners can focus on whether the goal is a more traditional bias-ply appearance or a radial option in the same 13-inch fitment family, while still checking the actual wheel setup on any car that has been altered over time.
Choosing the Right Tire
What should I consider when choosing a 155R13 or 6.15-13 tire for a 1970 Mazda 1200?
Start with the correct primary size and construction for the way the car is being kept. The 1970 Mazda 1200 can use a 155R13 radial or a 6.15-13 bias-ply, so the key factors are period-style appearance, intended road use, and the actual wheel setup on the car.
After that, compare practical details such as rim compatibility, brand, tire series, and how closely the tire matches your restoration or driving goals. A lightly used collector car may point toward the bias-ply route, while a road-driven example may lean toward the radial size. Either way, inspect wheel condition and verify clearance before final selection.
What brands offer tires for the 1970 Mazda 1200?
For the 155R13 radial size, available choices include Michelin and Dunlop. Those brands appear in vintage-appropriate 13-inch radial offerings for the 1970 Mazda 1200, with both current options using a blackwall sidewall style.
Brand selection should be part of a broader comparison rather than the only decision point. It helps to look at the tire series, construction, and wheel-width suitability alongside the brand name, especially on a compact car where tire proportions matter visually. That approach gives a better match for restoration character or regular road use than choosing by brand alone.
What tire series are available for the 1970 Mazda 1200?
The 155R13 radial fitment for the 1970 Mazda 1200 includes series such as Michelin XAS-FF and Dunlop SP Sport Aquajet. Both are blackwall radial offerings in the correct 13-inch size family for owners considering the radial path.
Series names can help separate one vintage-style radial option from another when the size itself is already settled. A buyer comparing them should still keep the basic fitment priorities first: correct rim diameter, suitable wheel width, and the overall look desired on the car. Once those points are confirmed, the series choice becomes a matter of preference within the proper size.
Restoration & Appearance
Which tire should I choose for a period-style 1970 Mazda 1200?
For a period-style 1970 Mazda 1200, the 6.15-13 bias-ply size is the natural starting point because it preserves the older numeric sizing format and traditional bias-ply construction. The 155R13 radial remains a correct primary fitment choice, but it creates a different presentation and ownership experience.
The best choice depends on whether the goal is authenticity of look, regular road use, or a balance between the two. A carefully restored car may favor the bias-ply route, while a car driven more often may justify the radial option. When exact originality matters, compare the tire decision against vehicle-specific historical references and the car's actual wheel setup.
How does tire construction affect the appearance of a restored 1970 Mazda 1200?
Tire construction changes more than driving feel on a restored 1970 Mazda 1200; it also influences the car's overall visual character. A 6.15-13 bias-ply carries the traditional vintage sizing language and look, while a 155R13 radial presents the car in a later, more modern tire format.
That difference matters on a small, lightly styled car where tire proportions are easy to notice. Owners aiming for a restoration-oriented appearance often start by deciding whether the car should look period-first or road-use-first, then compare the available tire style within that direction. The choice should still be checked against wheel width and the condition of the suspension and steering components.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1970 Mazda 1200?
Yes. Even though the 1970 Mazda 1200 uses 13-inch tire sizes, later wheel changes, suspension alterations, or body modifications can change how well a tire works on the car. That is especially important when choosing between the 155R13 radial and 6.15-13 bias-ply constructions.
A Mazda 1200 with aftermarket wheels should be checked for wheel width and general compatibility before any tire is selected. Ride height changes, replacement springs, or fender work can also affect steering and body clearance. Confirming the actual setup on the car is more useful than assuming any tire in the correct nominal size will behave the same.
What should I inspect before driving a 1970 Mazda 1200 on new tires?
Before road use, inspect the wheels for condition and proper size, then confirm the tires are correctly mounted and inflated for their application. It also helps to look over the suspension, steering, and brakes on a 1970 Mazda 1200, since an older compact car can reveal worn components once fresh tires are installed.
Tire inspection should continue after installation rather than ending there. Check for adequate clearance at full steering lock, watch for uneven wear, and make sure the car tracks consistently on the road. A short local drive followed by another visual inspection is a sensible way to confirm that the wheel, tire, and chassis combination is working properly.
How should 155R13 or 6.15-13 tires on a collector 1970 Mazda 1200 be maintained?
Collector-car tires should be inspected regularly even when the 1970 Mazda 1200 is driven only occasionally. Whether the car wears 155R13 radials or 6.15-13 bias-ply tires, keep an eye on pressure, tread condition, sidewall cracking, bulges, cuts, and any sign of slow air loss.
Storage conditions matter just as much as mileage on a lightly used vintage car. Keeping the Mazda away from prolonged heat, direct sunlight, standing moisture, and ozone sources can help preserve tire condition between drives. It is also smart to inspect the tires before longer outings, since age-related deterioration may appear long before the tread looks worn out.
