Classic Tires for Classic American Bikes
Finding the correct tires for correctly restored Harley-Davidsons often used to be troublesome or ended up in compromises. Our selection of classic tires offers the the possibility to equip almost any classic American two-wheeler with tires of authentic treads and size. We offer products of the renowned US manufacturer Coker as well as some alternatives by the Korean company Shinko. The Coker tires are so well made that even the rigorous AMCA (Antique Motorcycle Club of America) judges accept them as stock replacement.
Unlike today’s size indication classic tires were often identified by and marked with the outside diameter. To determine the required rim size you typically deduct 6” from the indicated OD.Example: a 26 x 3” tire requires a 26 - 6 = 20” rim.
