Where can I find Street tires for a 1972 Cl350 Honda Motorcycle?

If you know the sizes, try your local dealers or tire company websites. If you don't know the size, ask at the local Honda dealer if they can locate the size or find a Clymer manual for the 72 Honda. Tire size is a 3.50 - 18 on the rear, and a 3.50 - 19 on the front, both require tubes.
