I seem to remember that it's recommended 3 yrs max on steer tires and 5 yrs max on rears. That is regardless on indoor/outdoor storage and visual condition of the tires. IMHO tires are much cheaper than possible damage to coach and expenses of roadside service in the event of a blowout. (have had 2 on inside dual with minimal damage)
