Coker Classic | 4 Inch Whitewall | L78-15

Coker Classic L78-15 bias ply 4 inch wide whitewall tires are an excellent upgrade for a car that originally had 800-15 or 820-15 tires. This includes many American classic cars from the 1950s and 1960s, like Cadillac, Lincoln and more. The L78 tires also work well on hot rods and custom cars, as the 4 inch whitewall provides the timeless old school look. Coker wide white wall tires feature genuine whitewall construction and authentic deluxe tread designs. These Coker Classic bias ply wide whitewalls are made in the USA. DOT and ECE (European Union) approved, and backed by our life of the tread warranty.

Genuine Wide Whitewall Tire

This product features a genuine wide whitewall sidewall style. This means that the bright white rubber is added directly to the tire sidewall during initial construction of the carcass, resulting in a truly integrated, high-quality product after vulcanization. Wide whitewall tires were a very popular choice from the 1930's through the end of the 1950's, and were eventually phased out of mainstream production by 1962. Originally, wide whitewall tires featured a bias ply construction, but now Coker Tire offers them in original style bias ply and modern radial construction.

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.

Is this the same as a 205/75/15?
By Edwin J Parra on January 31, 2019

This would be more like a 235/75R15. A 670-15 would be more like a 205/75R15. Click Here

Will these work for stock 1955 Chevrolet wheels, or 205/75-15 replacement?
By Mark Carrillo on July 24, 2018

These are about 3 sizes larger than standard equipment, so we could not insure fitment. We suggest either a 670-15 or a 205/75R15 for a 1955 Chevrolet.
