Genuine Raised White Letter Tire
This is a raised white letter tire, sometimes called RWL for short. Raised white letter tires became common in the late sixties on muscle cars like the Pontiac GTO and high performance pony cars, like the Ford Mustang. Raised white letter tires feature white rubber that is built into the tire's sidewall when the carcass is being assembled. The letters are formed when the tire is vulcanized in a curing mold, and then buffed clean to reveal bright white letters. Look for this classic style from our featured brands like Pro-Trac, Firestone Wide Oval and BFGoodrich Radial T/A tires.
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.
Firestone Wide Oval Radial Tires
Firestone Wide Oval radial tires take the popular styling and fitment of the original bias ply Wide Oval and give it the excellent handling and ride quality of a modern radial. Available in 10 sizes, the Firestone Wide Oval radial product line is a favorite for muscle car enthusiasts.
AWARD WINNER!
The SEMA Automotive Restoration Market Organization (ARMO) awarded Coker Tire a 2025 Best New Product award in the Drivetrain, Brakes and Suspension category, recognizing the Firestone Wide Oval radial size product line expansion.
Firestone Tires for Collector Vehicles
The vintage line of Firestone tires fits a wide range of cars, trucks and motorcycles built from the 1900's through the 1970's. Firestone Non Skid tires, Firestone Deluxe Champion tires, Firestone Wide Oval tires and many more famous styles and sizes are available to fit military vehicles, motorcycles and classic commercial trucks. With whitewalls, redlines, raised white letters and other classic sidewall styles, this product line is one of the most extensive and popular brands for classic cars.

Frequently Asked Questions
Fitment & Compatibility ▼
The Firestone Wide Oval Radial RWL ER60-15 is designed for classic performance vehicles that require a 15-inch wheel application and a vintage-style tire profile. Fitment depends on the vehicle’s original specifications, wheel width, suspension clearance, and brake setup. This tire features a 25.80-inch overall diameter and 8.60-inch section width, which should be compared with your current tire dimensions.
Before installation, verify fender clearance, steering movement, and suspension travel. Vehicles with modified brakes, lowered suspension, or aftermarket wheels may require additional checks to confirm proper compatibility.
The Firestone Wide Oval Radial RWL ER60-15 can be compatible with original muscle car wheels when the wheel diameter, width, and vehicle specifications match the tire requirements. The tire is designed around classic performance applications where period-correct appearance is important.
Owners should confirm that their wheels support the tire’s dimensions and load requirements. Original wheels that have been restored, widened, or replaced should be measured carefully to ensure proper fitment and correct sidewall appearance.
The Firestone Wide Oval Radial RWL ER60-15 may fit vehicles with upgraded brakes or suspension components, but clearance must be verified. Brake conversions, larger calipers, altered spindles, and modified suspension systems can change the available space around the tire and wheel assembly.
The tire’s 15-inch rim requirement does not automatically guarantee compatibility with every brake upgrade. Check clearance during full steering lock and suspension compression to prevent rubbing or interference during real-world driving.
Tire Size Equivalents & Conversions ▼

The Firestone Wide Oval Radial RWL ER60-15 may replace another 15-inch tire size if the overall dimensions, load requirements, and vehicle clearances are appropriate. Wheel diameter alone does not guarantee compatibility because width and profile also affect fitment.
Before changing sizes, compare the existing tire’s overall diameter, section width, and intended use. This helps prevent issues with rubbing, altered stance, and changes in vehicle handling characteristics.
