Blackwall Tire
Since the introduction of carbon black rocked the tire industry, the original recipe for most tires has been a solid black sidewall. For classics and collector cars alike, it's hard to beat the no-nonsense appeal of a classic blackwall style tire. British sports car, classic truck and even hot rod enthusiasts love the way a nice period correct blackwall tire looks on their vehicles.
Bias Ply Construction
Bias ply tire construction is a method that was used from the 1900's through the 1970's on passenger cars and light trucks. Bias ply tires feature ply cords that run at a 45 degree angle to the bead, and overlap in a crisscross pattern, depending on how many ply layers are used. This creates a strong tire, but bias ply tires have a tendency to follow breaks or ruts in the pavement. Bias ply tires are the most authentic choice for classic car restorations and traditional hot rod builds. Coker Tire offers a huge variety of bias ply tires for many applications.

Frequently Asked Questions
Fitment & Compatibility â–¼
Will the Firestone 700-18 Classic Blackwall Bias Ply Tire fit my vintage vehicle with 18 inch wheels? â–¼
The Firestone 700-18 Classic Blackwall Bias Ply Tire is designed specifically for vehicles that originally used a 700-18 bias ply size and require an 18 inch rim. It fits wheels between 3.75 and 4.00 inches wide, which aligns with many pre-1970s trucks, British cars, and early commercial vehicles.
With an overall diameter of 32.50 inches and section width of 8.00 inches, it maintains period-correct proportions. Fitment depends on original specifications, so checking your vehicle’s factory size or current tire markings is essential before installation.
Will the Firestone 700-18 Classic Blackwall Bias Ply Tire work with modern brake upgrades? â–¼
The Firestone 700-18 Classic Blackwall Bias Ply Tire itself does not directly interfere with brake upgrades, but wheel clearance becomes critical. Many disc brake conversions require wider or differently offset wheels, which may fall outside the 3.75 to 4.00 inch range.
If wider wheels are used, the tire’s shape may change, affecting section width and contact patch. Additionally, altered offset can push the tire closer to fenders or suspension components, so careful mock-up is recommended before final fitment.
Tire Size Equivalents & Conversions â–¼
What modern radial size is closest to the Firestone 700-18 Classic Blackwall Bias Ply Tire? â–¼
The Firestone 700-18 Classic Blackwall Bias Ply Tire does not have a perfect modern radial equivalent, but sizes like 225/75R18 or similar may come close in diameter depending on the application.
However, radial replacements often have shorter sidewalls and different section widths, which changes stance and handling. If authenticity and original geometry are priorities, staying with the 700-18 bias ply size is the better choice.
How does the Firestone 700-18 Classic Blackwall Bias Ply Tire compare to metric sizing in width? â–¼
The Firestone 700-18 Classic Blackwall Bias Ply Tire has an 8.00 inch section width, which roughly corresponds to a metric width around 200 to 215 mm depending on conversion.
However, bias ply tires have a more rounded tread profile, so the actual contact patch is narrower than a comparable radial. This affects grip and steering feel compared to modern tires.
Performance & Use Case â–¼
How will the Firestone 700-18 Classic Blackwall Bias Ply Tire drive on modern highways? â–¼
The Firestone 700-18 Classic Blackwall Bias Ply Tire provides a period-correct driving experience rather than modern radial precision. It will feel softer and more compliant due to the tall sidewall.
At highway speeds, expect some wandering or tracking along road grooves. This is normal for bias ply construction and requires more steering input compared to modern tires.
Construction, Durability & Load Capacity â–¼
What does the 6 ply construction of the Firestone 700-18 Classic Blackwall Bias Ply Tire mean? â–¼
The Firestone 700-18 Classic Blackwall Bias Ply Tire uses a 6 ply poly construction, which provides strength and durability suitable for vintage trucks and heavier vehicles.
This construction supports a maximum load of 1520 lbs at 36 psi. It offers resistance to punctures and maintains structural integrity under load.
Installation & Maintenance â–¼
How should the Firestone 700-18 Classic Blackwall Bias Ply Tire be inflated? â–¼
The Firestone 700-18 Classic Blackwall Bias Ply Tire should be inflated according to load requirements, up to a maximum of 36 psi. Proper inflation ensures optimal performance.
Underinflation increases heat and wear, while overinflation reduces contact patch and ride comfort. Regular pressure checks are essential.
How should the Firestone 700-18 Classic Blackwall Bias Ply Tire be stored when not in use? â–¼
The Firestone 700-18 Classic Blackwall Bias Ply Tire should be stored in a cool, dry environment away from direct sunlight. This prevents material degradation.
Keeping the tire off the ground and maintaining slight inflation helps preserve its shape during long-term storage.
