Molded from isobutylene isoprene rubber (IIR), they are built to resist aging and improve airtightness compared with standard compounds. The TR-13 straight valve and reinforced valve seat help reduce leaks and cracking, while a 30 psi maximum rating keeps inflation within safe limits for typical garden and utility equipment.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these inner tubes extend the life of my wheels?\u003c\/h3\u003e\n\u003cp\u003eReplacing a failed inner tube is a quick way to bring an old wheel back into service without buying a new tire or rim.
