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.
S Speed Rating
S Speed Rated: Up to 112 mph (180 km/h). Often required OE for higher performance trim level classic automobiles.
Bias Look Radial Tire
The term "bias look radial" is something that Coker Tire created when we introduced the American Classic bias look radial product line. This means the tire has the appearance and the sizing profiles of a vintage bias ply tire, with modern radial construction. This provides an original look with a smooth ride and longer tread life, compared to bias ply tires. We offer bias look radial tires for vehicles ranging from the 1920's through the 1970's.
American Classic Radial Tires
American Classic tires are made in the USA and designed for use on classic cars, hot rods and customs. The most popular product line under the American Classic brand is the bias look radial, a tire that looks like a vintage bias ply tire but rides and handles like a modern radial tire.
American Classic Tires for Collector Cars
American Classic radial tires includes P-metric radials (such as 235/75R15) and the famous "bias look radial" (such as 670R15). American Classic radial tires are offered in wide whitewall, narrow whitewall, and black sidewall in select sizes, developed specifically for 1940's, 1950's and 1960's classic cars. These tires feature a classic tread design and a beautiful sidewall that's built into the tire from day one of production.
Please Note
- Bias Look Radial tires feature genuine radial tire construction with bias ply tire size, profile and styling. These tires are built in brand new molds using modern materials and tooling. Typically the sizing is the same as their Bias Ply equivalents with the addition of 'R' in the size value. Tire mounted on wheel for demonstration purposes only. Wheel and other accessories are not included. Please note that dimensions listed (tread width, section width and overall diameter) are non-scientific and based on an inflated tire, mounted to a wheel. Dimensions may vary due to rim width and inflation pressure. Please note Chemical Guys Tire and Rubber Cleaner and Adams Polish Tire shine has been linked to Whitewall browning and should not be used. We recommend using our line of tire care products.

Frequently Asked Questions
Fitment & Compatibility ▼
The American Classic Radial 820R15 Bias Look Radial Blackwall Tire is designed for collector vehicles that originally used bias ply tire sizing but whose owners want modern radial driving characteristics. According to the product information, it is intended for classic cars, trucks, and hot rods, making it suitable for many vehicles from the 1920s through the 1970s that originally used comparable bias ply dimensions.
Before purchasing, verify the original tire size, wheel diameter, and available clearance on your vehicle. Even when a tire appears correct on paper, wheel width, suspension modifications, ride height changes, and steering components can affect compatibility. Confirming fitment before installation helps avoid rubbing, clearance issues, and unexpected changes in vehicle stance.
The American Classic Radial 820R15 Bias Look Radial Blackwall Tire is built specifically for 15-inch wheel applications, making it a potential fit for many factory-equipped collector vehicles that originally used 15-inch wheels. Its bias-look sizing profile was created to closely resemble the dimensions and appearance of vintage bias ply tires while providing radial construction benefits.
Wheel diameter alone does not guarantee compatibility. Wheel width, bead profile, condition, and vehicle-specific fitment requirements should also be verified. Owners using original steel wheels generally find bias-look radial products easier to integrate than modern low-profile radials because the visual proportions remain closer to factory specifications.
Tire Size Equivalents & Conversions ▼
The American Classic Radial 820R15 Bias Look Radial Blackwall Tire was specifically developed around the concept of bias-look radial sizing. The product description notes that sizing is typically the same as comparable bias ply equivalents, with the addition of the letter “R” indicating radial construction.
For many collector vehicle applications, owners use the 820R15 as a radial alternative to an original 820-15 bias ply tire. Even so, fitment should always be verified on the specific vehicle. Differences in wheel width, inflation pressure, suspension geometry, and manufacturing tolerances can influence the final installed dimensions.
The American Classic Radial 820R15 Bias Look Radial Blackwall Tire was engineered to maintain the visual proportions associated with vintage bias ply tires. This design philosophy helps preserve wheelwell appearance and overall vehicle stance, making it attractive for restoration-focused applications.
The manufacturer also notes that dimensional figures can vary based on wheel width and inflation pressure. This means actual installed measurements may differ slightly from published specifications. Buyers seeking exact restoration fitment should consider mounted dimensions, wheel specifications, and vehicle-specific clearance requirements before finalizing a purchase decision.
Performance & Use Case ▼
The American Classic Radial 820R15 Bias Look Radial Blackwall Tire was designed to combine vintage appearance with the driving characteristics typically associated with radial construction. The steel belted radial design helps the tire maintain a more stable contact patch on the road, which can improve ride comfort and reduce the wandering sensation often experienced with older bias ply tires.
For owners who regularly drive their collector vehicles, the difference is often most noticeable on highways and longer trips. Steering response generally feels more predictable, and the vehicle may track straighter over uneven pavement. The result is a driving experience that preserves period-correct styling while improving everyday usability.
The American Classic Radial 820R15 Bias Look Radial Blackwall Tire was developed for collector vehicles that spend real time on the road rather than remaining exclusively on display. Its steel belted radial construction is intended to provide smoother highway performance and better long-distance comfort than many traditional bias ply alternatives.
The tire also carries an S speed rating, indicating suitability for speeds up to 112 mph under appropriate conditions. While few classic vehicle owners regularly approach those speeds, the rating provides additional confidence for normal interstate travel. Proper inflation, alignment, and suspension condition remain important factors in achieving the best highway performance.
Construction, Durability & Load Capacity ▼
The American Classic Radial 820R15 Bias Look Radial Blackwall Tire uses what Coker Tire describes as Bias Look Radial construction. This means the tire visually resembles a vintage bias ply tire while incorporating genuine radial internal construction. The design preserves classic styling cues that restoration enthusiasts value.
The concept allows owners to maintain period-correct appearance without giving up many of the benefits associated with radial technology. Vintage proportions, sidewall styling, and tread appearance remain consistent with classic vehicles, while the internal structure supports improved ride quality, durability, and road manners for modern driving conditions.
The American Classic Radial 820R15 Bias Look Radial Blackwall Tire was developed for collector vehicles that are actively driven rather than exclusively displayed. Modern materials, new molds, and steel belted radial construction all contribute to a tire designed for real-world use.
Durability depends heavily on factors such as inflation pressure, storage conditions, alignment, suspension health, and driving habits. Owners who maintain proper tire pressures and regularly inspect their vehicles typically achieve the best service life. Consistent maintenance remains one of the most important contributors to long-term performance and reliability.
Installation & Maintenance ▼
Long service life begins with proper inflation, regular inspections, and maintaining correct vehicle alignment. The American Classic Radial 820R15 Bias Look Radial Blackwall Tire can only perform at its best when suspension and steering components are functioning correctly and the tire is operated within appropriate conditions.
Owners should periodically inspect for uneven wear, verify air pressure, monitor alignment-related issues, and address suspension problems promptly. Checking clearance after any vehicle modification is also recommended. Consistent maintenance not only helps extend tire life but also preserves the ride quality, highway stability, and appearance that make this bias-look radial attractive to collector vehicle owners.
