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
The Firestone Non Skid All Black 32x4 is designed for a 24-inch rim diameter, so wheel diameter is the first requirement. A vehicle using original 24-inch tire wheels may be a strong candidate if the wheel is structurally sound and intended for 32x4 sizing. Antique wheels should be inspected for cracks, bent flanges, rust scale, or damaged spoke structure before mounting.
The listed 4.08-inch section width and 32.75-inch overall diameter help confirm outer and inner clearance. Buyers should measure space near fenders, steering arms, brake rods, and springs with the steering turned fully in both directions. Clearance checks matter because antique chassis movement can be greater than expected once the vehicle is loaded and driven.
The product page notes Firestone High Pressure tires fit many antique automobiles, including Ford Model T applications. Exact fitment still depends on production year, wheel type, and any modifications completed over the vehicle’s life. Many early vehicles changed wheel dimensions during production, so matching existing verified size markings or factory references is the safest path.
The narrow profile helps preserve original steering feel and visual proportions often associated with Model T restorations. Buyers with replacement hubs, later brake conversions, or aftermarket wheels should verify bead seat dimensions carefully. A car labeled as a Model T may no longer retain stock wheel hardware, and that can change tire requirements significantly.
Tire Size Equivalents & Conversions â–¼
There is rarely a perfect modern metric equivalent for a Firestone Non Skid All Black 32x4 because early high-pressure sizing uses a different measurement system than modern passenger tire formats. Diameter, section width, load ability, and wheel fitment all need to be considered together rather than matching one number alone.
The listed dimensions of 32.75 inches overall diameter and 4.08 inches section width show how tall and narrow the original format is. Many modern tires are wider and shorter, which can change stance, steering effort, gearing, and speedometer accuracy. Owners seeking authenticity usually stay with the original 32x4 format instead of converting.
Original wheel width is important because sidewall shape and bead seating depend on correct rim proportions. Very narrow or very wide wheels can distort tire profile, change tread contact behavior, and affect ride quality. Antique wheels should be measured carefully rather than assumed correct based on appearance.
The product page notes dimensional measurements are non-scientific and can vary with rim width and inflation pressure. That is an important buying signal because tire shape is influenced by the wheel underneath it. Preserving intended wheel width helps the Firestone Non Skid All Black 32x4 perform and look as expected.
Performance & Use Case â–¼
The Firestone Non Skid All Black 32x4 is built for vintage applications, so local road driving at moderate speeds is a natural use case when the vehicle is mechanically sound. Owners can expect authentic vintage response rather than modern isolation. Steering feedback and road texture are usually more noticeable.
The tall narrow profile can roll smoothly over imperfections, but pavement seams and crowned roads may still be felt through the chassis. Proper inflation pressure is important because antique vehicles are light and sensitive to pressure changes. Moderate speeds and regular inspections are the best approach for enjoyable local use.
The Firestone Non Skid All Black 32x4 is a strong candidate for show-focused owners because the product emphasizes period-correct construction, authentic sidewall branding, and proportions suited to early vehicles. Correct tire appearance often has a large visual impact because antique cars display so much wheel and sidewall area.
Concours-minded buyers usually value accurate stance, proper sidewall style, and era-correct sizing more than ultimate modern handling. The blackwall finish suits many restorations seeking an honest factory-era presentation. Clean mounting, correct inflation, and detailed wheel hardware often make the total presentation even stronger.
Construction, Durability & Load Capacity â–¼
Bias ply construction uses overlapping cord layers arranged diagonally across the casing. That design was standard for many decades and is historically correct for antique vehicles. Owners choosing the Firestone Non Skid All Black 32x4 usually do so because they want authentic period construction rather than a modern reinterpretation.
In use, bias ply tires often feel different from radials in steering response, tracking, and sidewall behavior. Regular pressure checks and realistic speed expectations are important. The design is durable when used appropriately, but driving habits should match the vintage vehicle and tire combination.
The product lists 6 ply nylon construction, which indicates a robust casing structure suited to vintage load demands. Nylon has long been valued for strength and resilience in tire construction. For antique applications, that can support dependable service when the tire is maintained correctly.
Durability still depends on storage, inflation pressure, alignment, and road hazards. Underinflation can create excess heat, while overloading can stress the casing unnecessarily. Even a strong tire benefits from regular inspections for cuts, sidewall damage, and uneven wear. Good maintenance is part of durability.
The Firestone Non Skid All Black 32x4 is primarily an authenticity-focused product. Construction type, sizing format, sidewall presentation, and intended applications all align with vintage restoration priorities rather than modern sports-car priorities.
That does not mean poor usability. It means the tire should be evaluated within the context of antique vehicle operation. Buyers wanting correct looks, proper fitment, and period driving character will usually see the most value. Buyers chasing modern performance metrics should choose with that difference in mind.
Installation & Maintenance â–¼
Yes, the product page lists the Firestone Non Skid All Black 32x4 as Tube Type. That means a proper tube is part of the installation system rather than an optional extra. Tube sizing, valve stem style, and overall condition should match the wheel and tire application.
Tube-type installation also means the wheel interior must be clean and smooth. Rust flakes, burrs, and debris can damage a tube over time. Many owners also use the recommended flap or liner when applicable to protect the tube from spoke ends or wheel irregularities.
Clean, dry, indoor storage is best. Keep the tire away from direct sunlight, electric motors, ozone sources, and extreme temperatures. Long exposure to damaging environments can age rubber faster than careful seasonal use ever would.
If the vehicle is stored for months, maintaining correct pressure and moving the car occasionally can help reduce flat spotting. Some owners place the vehicle on stands depending on storage conditions and chassis design. A brief inspection before the next driving season is always worthwhile.
