Coker Classic | Redline | 185R15

185R15 Coker Classic Redline Tires are perfect for European sports cars, including 1969 through 1976 Triumph TR6. They are also excellent replacements for 640-15 bias ply tires that came on many classic Jaguar, BMW, Austin and Volvo applications from the '50s, '60s and '70s. Redline Radial tires combine classic styling with the smooth comfortable ride of a long-lasting radial tire. DOT and ECE (European Union) approved, with an all-season tread design and backed by our life of the tread warranty.

Genuine Redline Tire

This product features a genuine redline sidewall style, sometimes known as a red stripe, due to the thin 3/8-inch strip rubber. This means that the red rubber is added directly to the tire sidewall during initial construction of the carcass, resulting in a truly integrated, high-quality product after vulcanization. Redline tires hit the American automobile market in 1964 with the introduction of the Pontiac GTO and remained a popular muscle car tire until around 1970. Dual redline tires (two red stripes) were an option on Ford Mustangs, and are now reproduced in original bias ply construction as well as radial construction. 

Radial Tire Construction

Radial tires were first introduced by Michelin in the 1950's, and by the mid 1970's, all American cars came from the factory with radial tires. Radial tire construction means that the tire's ply layers are positioned at a 90 degree angle to the bead. This allows the tire to flex and glide over bumps and breaks in the road. Radial tires provide a smoother ride and longer tread life than bias ply tires. We offer wide whitewall radial tires, as well as narrow whitewalls, redlines, gold lines and high performance radial tires.

Have a 1969XKE Jag; need tires. Is the coker classic 185R15 aspect ration 65,70,75 or 80?
By Jane Spakoski on April 28, 2018

All radial tires, as indicated with "R" in the size, and when aspect ratio is not stated, are known to have an "80" aspect ratio. So, a 185R15 tires is equal to a 185/80R15.
