The 1976 Mazda Truck Rotary Truck stands apart from other compact pickups of its era, pairing a light-duty truck chassis with Mazda’s rotary-engine identity at a time when small imported trucks were gaining real traction in the U.S. market. That unusual combination makes tire choice more than a routine replacement decision, especially for an owner trying to preserve the truck’s character. This model uses a 735-14 bias-ply tire on a 14-inch rim. In that size, available choices include traditional blackwall and narrow whitewall treatments in BFGoodrich’s Silvertown Classic Bias Ply series, along with modern radial equivalents for owners considering a different driving setup.
Which Tire Size Is Right for The 1976 Mazda Truck Rotary Truck
The 1976 Mazda Truck Rotary Truck uses one primary tire size: 735-14. That is a bias-ply fitment on a 14-inch rim, and the same size carries across the covered Base model. The main decision is not sorting through multiple primary sizes, but choosing the right look within 735-14 or deciding whether a modern radial equivalent makes sense for the truck’s wheels, use, and overall setup.
A 735-14 numeric bias-ply size uses the leading number to indicate an approximate nominal section width of 7.35 inches, while the final number identifies a 14-inch rim. On the 1976 Mazda Truck Rotary Truck, this is the primary vintage-style fitment and suits an owner who wants to stay with the truck’s original-style construction approach. Available options in this size include BFGoodrich Silvertown Classic Bias Ply tires in blackwall and 1.00 inch narrow whitewall form. It is the right place to start when the goal is period-style appearance, correct rim compatibility, and a traditional bias-ply presentation.
Fitment is straightforward for the covered 1976 Mazda Truck Rotary Truck sub-model. The key point is confirming that the truck still has its original 14-inch wheel setup before choosing among the available 735-14 bias-ply options or evaluating a radial equivalent.

1976 Mazda Truck Rotary Truck Base
The 1976 Mazda Truck Rotary Truck Base uses the same 735-14 bias-ply tire as the main model fitment. That keeps selection focused on tire appearance and driving goals, with the choice centered on blackwall versus narrow whitewall or on whether a radial alternative should be checked against the truck’s wheel and clearance needs.
Bias-Ply to Radial Tire Conversion for the 1976 Mazda Truck Rotary Truck
The original 735-14 tire size has three radial-equivalent options. 185R14 is the 80-series metric radial equivalent, P195/75R14 is the 75-series P-metric radial equivalent, and P205/70R14 is the 70-series P-metric radial equivalent. These choices step through different sizing conventions and profile families while staying in a comparable replacement conversation for the original size. A 4 to 6 inch rim-width range is associated with these equivalents, so wheel width, overall dimensions, and clearance should all be checked before changing from the primary bias-ply fitment.
Modern Radial Equivalents

Tire Size & Fitment
What tire size fits a 1976 Mazda Truck Rotary Truck?
The 1976 Mazda Truck Rotary Truck uses a 735-14 tire size. That is a numeric bias-ply fitment built for a 14-inch rim, and it is the primary size associated with this model.
For most buyers, the next step is confirming that the truck still carries the correct wheel diameter and has not been changed to a different aftermarket setup over the years. Once that is settled, the real choice becomes staying with a 735-14 bias-ply for a traditional look or comparing the available radial equivalents if road-use priorities point in that direction.
What size rim does a 1976 Mazda Truck Rotary Truck use?
The primary tire fitment for the 1976 Mazda Truck Rotary Truck is built around a 14-inch rim. The 735-14 size itself confirms that wheel diameter, and the available bias-ply products in this fitment are also built for a 14-inch wheel.
Wheel diameter should be verified before any tire purchase, especially on an older truck that may have seen replacement wheels at some point in its life. Width matters too: the available 735-14 bias-ply tires are paired with 5.00 to 5.50 inch rim widths, while the radial equivalents reference a 4 to 6 inch range, so both diameter and width deserve a quick check.
Does the 1976 Mazda Truck Rotary Truck Base use the same tire size?
Yes. The 1976 Mazda Truck Rotary Truck Base uses the same 735-14 bias-ply tire size as the main model fitment. That keeps tire selection simple, with no separate primary size to sort out for the covered sub-model.
Even with shared fitment, it is still worth checking the truck itself before replacing tires. Older pickups are often updated with different wheels, and that can affect both rim width and the practical suitability of either a bias-ply tire or a radial equivalent. Once the wheel setup is confirmed, the choice mainly comes down to appearance, construction, and intended driving use.
Bias-Ply & Radial Options
Is 735-14 a bias-ply or radial tire for the 1976 Mazda Truck Rotary Truck?
On the 1976 Mazda Truck Rotary Truck, 735-14 is the primary bias-ply tire size. The available products in that size are bias-ply tires, which makes this the traditional fitment path for owners who want to stay with the original-style construction approach.
That matters because construction choice affects both appearance and setup decisions. A bias-ply tire preserves a more vintage presentation, while a radial alternative moves the truck into a different fitment conversation. Before changing construction, check wheel width, overall tire dimensions, and clearance at the fenders and steering components rather than assuming every 14-inch option behaves the same way.
What radial tire sizes are equivalent to 735-14?
Radial equivalents for 735-14 include 185R14 as an 80-series metric radial, P195/75R14 as a 75-series P-metric radial, and P205/70R14 as a 70-series P-metric radial. No bias-look radial equivalent is attached to this size in the available fitment range.
Those options give the owner more than one radial format to consider, but they should be treated as alternatives rather than automatic replacements. A 4 to 6 inch rim-width range is associated with the equivalents, so wheel width is an important first check. After that, compare the actual truck’s clearance and overall stance before moving away from the original 735-14 bias-ply setup.
What should I check before converting my 1976 Mazda Truck Rotary Truck from bias-ply to radial tires?
Start by confirming the truck’s wheel diameter and width, then compare the chosen radial equivalent against the original 735-14 fitment. For this truck, the radial alternatives are 185R14, P195/75R14, and P205/70R14, with a referenced rim-width range of 4 to 6 inches.
Clearance should be checked at the front suspension, steering travel, and fender openings before making the switch. It is also smart to look at the truck’s overall condition, including springs, alignment, and any modifications that may affect space around the tire. Converting from bias-ply to radial is a setup decision, not just a size-label decision, even when the rim diameter stays at 14 inches.
Choosing the Right Tire
What should I consider when choosing a 735-14 tire for a 1976 Mazda Truck Rotary Truck?
Begin with the correct primary size and construction. For the 1976 Mazda Truck Rotary Truck, that means a 735-14 bias-ply tire on a 14-inch rim, with available products in BFGoodrich’s Silvertown Classic Bias Ply line.
From there, the decision usually comes down to how the truck will be presented and used. A blackwall gives a plainer, utility-oriented look, while a narrow whitewall changes the visual character without changing size. Rim-width compatibility should still be confirmed, especially on a truck that may no longer have its original wheels, and restoration goals may point toward keeping the traditional bias-ply construction.
What sidewall styles are available for 1976 Mazda Truck Rotary Truck tires?
The available 735-14 tires for the 1976 Mazda Truck Rotary Truck come in two sidewall styles: blackwall and narrow whitewall. Both are offered within the same BFGoodrich Silvertown Classic Bias Ply series, so the difference is primarily visual rather than a change in tire size or basic construction.
That makes sidewall style an appearance decision tied closely to the way the truck is being restored or presented. A blackwall tends to keep the look simple and work-truck oriented, while a narrow whitewall adds a more dressed-up vintage touch. Either way, the buyer should still confirm wheel dimensions and overall tire condition priorities instead of choosing by sidewall style alone.
How do I choose between the available 735-14 tires for a 1976 Mazda Truck Rotary Truck?
The available 735-14 options are closely related, so the main differences are sidewall treatment, product weight, and the look you want on the truck. Both choices are BFGoodrich bias-ply tires in the Silvertown Classic Bias Ply series and share the same 14-inch rim diameter with a 5.00 to 5.50 inch rim-width specification.
That means selection is less about sorting through unrelated tire types and more about matching the truck’s presentation and use. A restoration-minded owner may focus first on visual character, while a buyer preparing the truck for regular casual driving may concentrate on wheel compatibility and overall setup. It also helps to confirm the actual wheel before choosing, since older trucks are often changed over time.
Restoration & Appearance
Which tire should I choose for a period-style 1976 Mazda Truck Rotary Truck?
A 735-14 bias-ply tire is the natural starting point for a period-style 1976 Mazda Truck Rotary Truck because it matches the truck’s primary vintage fitment approach. In the available range, that means BFGoodrich Silvertown Classic Bias Ply options rather than moving immediately to a modern radial substitute.
The remaining choice is largely about presentation. A blackwall keeps the look restrained, while a narrow whitewall gives the truck a more styled vintage appearance. When exact restoration accuracy matters beyond general period style, it is worth checking marque references or vehicle-specific historical material before settling on a sidewall treatment simply because it is available in the correct size.
How does tire construction affect the appearance of a restored 1976 Mazda Truck Rotary Truck?
Construction changes the visual character of the truck more than many buyers expect. A 735-14 bias-ply keeps the 1976 Mazda Truck Rotary Truck in a traditional vintage format, while a radial equivalent such as 185R14, P195/75R14, or P205/70R14 introduces a more modern sizing convention.
That difference can matter on a restored pickup where stance, sidewall shape, and overall presentation are part of the vehicle’s appeal. Owners focused on a period-style result often stay with the primary bias-ply size, while those prioritizing a different road-use feel may consider a radial alternative. Either path should still be checked against wheel width and clearance before the final decision is made.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1976 Mazda Truck Rotary Truck?
Yes. Modifications can change the way a tire fits on a 1976 Mazda Truck Rotary Truck even when the original size is known. Different wheels, altered ride height, suspension changes, or body modifications can all affect whether a 735-14 bias-ply or one of its radial equivalents remains a sensible choice.
That is why wheel diameter alone is not enough. Width, offset, steering clearance, and fender space should all be checked on the truck as it sits today. This matters even more when considering 185R14, P195/75R14, or P205/70R14 in place of the original-style bias-ply tire, since equivalent sizing still needs to be matched to the actual vehicle setup.
What should I inspect before driving a 1976 Mazda Truck Rotary Truck on new tires?
Before road use, inspect the wheels for correct diameter and visible damage, then check that the tires are mounted in the proper size and construction for the intended setup. It is also wise to look over suspension and steering components on a 1976 Mazda Truck Rotary Truck, especially if the truck has been sitting or has seen infrequent use.
A good pre-drive check should also include tire pressure, lug hardware, tread condition, sidewall condition, and any signs of rubbing once the truck is on the ground and turned lock to lock. Older collector vehicles can hide age-related issues even after new tires are installed, so a short, careful test drive and a follow-up inspection are worthwhile.
How should 735-14 tires on a collector 1976 Mazda Truck Rotary Truck be maintained?
Collector-vehicle tire care starts with regular inspection, even when mileage is low. On a 1976 Mazda Truck Rotary Truck running 735-14 tires, that means checking pressure, looking for cuts, bulges, cracking, uneven wear, or slow air loss, and making sure the truck is not spending long periods with neglected tires under load.
Storage conditions matter almost as much as driving habits. Keeping the truck away from prolonged heat, direct sunlight, moisture, and ozone sources can help preserve tire condition over time. It also helps to move the vehicle periodically and inspect the tread and sidewalls before every road outing, since vintage trucks often sit far longer between drives than modern daily drivers.
