Depends. Two things wear out tires -- mileage and dry rot. If tread's good, keep riding. But keep an eye on sidewalls for tell- tale indications of dry rot (surface cracking), caused by 1) lack of use. Rubber is composed of compounds that require exercise. They're meant to flex. If they don't flex, they lose their elasticity over time and become brittle, therefore subject to blow when ridden over sudden obstacles (potholes, bumps, etc.) 2) UV rays from sunlight and lack of use. Same result as above.
Rule of thumb with anything made of rubber (including gaskets, diaphragms, o-rings -- if it's old, it's questionable and you'd probably be better off renewing it. If for no other reason than peace of mind. Otherwise known as preventive maintenance. -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
