I used a front rib type tire Avon Speedmaster MK II 3.25-19 and a close match to the original, a Heidenau 3.25-19 M/C for a retro look. The bike wobbles excessively on limited access highways when linear grooves are scored into the concrete. On a modified original Bridgestone 350 build I put an Avon Roadrunner 100/90-18 on the rear.
