Howdy, Lovin' this conversation about tires. You can balance a square block of wood perfectly but it won't roll smoothly. Where can one find a tire truing machine? I understand why they have disappeared; (new radials are very round, better molds). However with old wire wheels and tube type tires (Mine are Firestone replicas by Coker) I know they are not round, yet balanced. Another question; Any thoughts about Nitrogen instead of regular compressor air? Should a car be jacked up to unload bias ply tires when not in use?
