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. 

Pro-Trac Tires

Pro-Trac made their name in the seventies, giving drivers a wild set tire size choices to get that perfect stance going. Front runners and all the rear tire you'd want are all a part of that classic Pro-Trac setup. Tubs and mini-tubs can get down with the original recipe right here, Pro-Trac tires.

Tire section width is listed at 12.6 on N50 15 Pro Trac, do you what size was tire mounted on to come up with 12.6? (10 in wheel)
By Bruce on April 25, 2018

The section width is an average number based on the tire being mounted on a rim between 8" and 10" wide. None of the numbers are scientific and can vary depending on the rim, the weight of the vehicle, and the tire inflation.
