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 â–¼
The Firestone Wide Oval Radial RWL GR60-15 is designed for 15-inch wheel applications, making it a logical choice for many factory-equipped muscle cars originally fitted with 15-inch performance wheels. Owners seeking an authentic appearance often appreciate that the tire preserves the period-correct Wide Oval profile while benefiting from radial construction.
Wheel diameter alone does not guarantee compatibility. Wheel width, bead profile condition, and overall tire clearance must also be evaluated. Original steel wheels and restoration-correct rally wheels commonly work well when they are structurally sound and appropriately sized for the tire. Verifying wheel condition before installation is especially important on vehicles retaining original components.
One of the strongest reasons enthusiasts choose the Firestone Wide Oval Radial RWL GR60-15 is its ability to preserve a classic muscle car stance. The tire uses authentic sidewall styling and a period-correct profile that closely resembles original Wide Oval tires, helping maintain the visual character expected on late 1960s and early 1970s performance vehicles.
Stance is influenced by overall tire diameter, sidewall height, and wheel selection. Even small changes in diameter can alter fender gap, rake, and vehicle posture. Owners pursuing factory-correct restoration standards often appreciate that the Firestone Wide Oval Radial line was developed specifically to deliver vintage proportions while benefiting from modern radial construction.
The Firestone Wide Oval Radial RWL GR60-15 appeals to many restomod owners because it combines vintage muscle car aesthetics with modern radial tire construction. Drivers often want the appearance of an original performance tire without accepting all of the ride and handling compromises associated with traditional bias ply designs.
Regular-use vehicles generally benefit from radial characteristics such as improved ride quality, better highway manners, and more predictable handling. The tire allows owners to maintain a classic appearance while supporting modern driving expectations. For enthusiasts seeking a balance between authenticity and usability, the Firestone Wide Oval Radial RWL GR60-15 is positioned specifically for that purpose.
Tire Size Equivalents & Conversions â–¼
The Firestone Wide Oval Radial RWL GR60-15 offers a combination of period-correct proportions and modern radial technology. Enthusiasts restoring or preserving classic muscle cars often prefer maintaining factory-era visual cues, including sidewall height, raised white lettering, and the recognizable Wide Oval profile.
Low-profile modern tires can dramatically change a vehicle's appearance and alter the character of the driving experience. The Firestone Wide Oval Radial allows owners to preserve authentic styling while benefiting from contemporary construction methods. This balance is a major reason the tire remains popular among collectors, restorers, and weekend drivers.
Performance & Use Case â–¼
The Firestone Wide Oval Radial RWL GR60-15 was developed to bridge the gap between authentic vintage appearance and modern road manners. Unlike traditional bias ply tires, radial construction typically delivers more predictable tracking, improved ride comfort, and greater stability during everyday driving.
Many enthusiasts notice reduced wandering on highways and more confident cornering compared with older bias ply designs. At the same time, the tire preserves the classic Wide Oval look that muscle car owners value. This combination makes it attractive for drivers who want authenticity without giving up the usability expected from a regularly driven collector vehicle.
The Firestone Wide Oval Radial RWL GR60-15 was designed with radial construction and carries an S speed rating, indicating capability for speeds up to 112 mph. For most classic muscle car owners, this provides more than enough capacity for normal highway and interstate travel.
Long-distance driving also benefits from radial tire characteristics such as smoother ride quality and more stable road tracking. Proper inflation remains important because tire pressure influences heat buildup, wear patterns, and overall performance. Maintaining recommended pressures helps maximize comfort and durability during extended highway use.
The Firestone Wide Oval Radial RWL GR60-15 is particularly well suited for vehicles that split time between road use and show appearances. The raised white lettering, authentic sidewall details, and period-correct tread styling create the visual impact many enthusiasts expect from a classic muscle car tire.
Beyond appearance, radial construction improves real-world drivability. Owners can enjoy smoother cruising, more consistent handling, and less of the wandering behavior often associated with traditional bias ply tires. This balance of aesthetics and usability makes the tire a strong choice for collector vehicles that are regularly exercised rather than stored exclusively for display.
Construction, Durability & Load Capacity â–¼
The most significant difference is internal construction. Traditional bias ply tires use overlapping cord plies arranged diagonally across the tire, while the Firestone Wide Oval Radial RWL GR60-15 uses radial ply construction. Although the exterior appearance closely resembles the original Wide Oval design, the driving experience is noticeably different.
Many enthusiasts choose the radial version because it offers smoother highway manners, more predictable handling, and longer tread life potential. The tire preserves the authentic muscle car look while reducing some of the compromises commonly associated with bias ply tires, particularly during extended road trips and higher-speed cruising.
Yes. The Firestone Wide Oval Radial RWL GR60-15 fits the concept of a bias look radial because it combines vintage tire proportions and styling cues with genuine radial construction. The sidewall profile, raised white lettering, and overall appearance are intended to replicate the look enthusiasts associate with classic muscle car tires.
This approach allows owners to maintain restoration-correct visual appeal while gaining many advantages of radial technology. Buyers who want their vehicle to appear factory-correct from a distance often appreciate that the tire retains the character of period tires without requiring the ownership compromises of traditional bias ply construction.
The Firestone Wide Oval Radial RWL GR60-15 carries an S speed rating, which indicates capability for speeds up to 112 mph under appropriate operating conditions. This rating aligns well with the intended use of most classic muscle cars and performance-oriented collector vehicles driven on public roads.
For the majority of owners, an S speed rating provides more than sufficient capacity for normal highway use. However, speed ratings assume proper inflation, correct load conditions, and good tire condition. Maintaining alignment and tire pressures helps ensure the tire performs as intended during sustained higher-speed driving.
The Firestone Wide Oval Radial RWL GR60-15 was developed specifically for enthusiasts who want authentic styling without limiting road use. Its modern radial construction supports the needs of owners who regularly drive their classic muscle cars on local roads, highways, and weekend events.
Durability is enhanced when the vehicle's suspension, alignment, and tire pressures are maintained properly. While no tire is immune to age, road hazards, or improper maintenance, the combination of modern construction and vintage appearance makes this tire a practical option for collector vehicles that are actively enjoyed rather than stored indefinitely.
Installation & Maintenance â–¼
Before installation, confirm that your vehicle uses a compatible 15-inch wheel and has sufficient clearance for the GR60-15 size. Buyers should inspect wheel condition, verify suspension integrity, and compare the tire's dimensions against the vehicle's existing setup to avoid unexpected fitment issues.
It is also wise to evaluate steering clearance and suspension travel before mounting the tires. Vehicles with aftermarket wheels, lowered ride height, or upgraded suspension systems may require additional measurements. Taking these steps before installation helps reduce the risk of rubbing, clearance conflicts, or stance-related surprises.
The raised white lettering is one of the defining visual features of the Firestone Wide Oval Radial RWL GR60-15. Routine cleaning helps maintain a bright appearance and preserves the authentic muscle car look that many owners seek.
The product information specifically notes that certain tire cleaning and dressing products have been associated with whitewall browning. Using tire care products intended for classic tires and avoiding known problem products can help maintain the appearance of the raised white letters while supporting long-term cosmetic preservation.
The Firestone Wide Oval Radial RWL GR60-15 is designed for enthusiasts who want a blend of historical appearance and modern drivability. Buyers should understand that fitment, ride quality, and handling characteristics are influenced by wheel width, alignment, suspension condition, and inflation maintenance.
Advanced ownership considerations include monitoring tire pressure regularly, checking clearance after suspension modifications, verifying speedometer accuracy when changing tire sizes, and inspecting for rubbing under full suspension compression. Paying attention to these details helps owners maximize performance, appearance, and durability while preserving the classic muscle car experience the tire was designed to deliver.
