Goodyear 's DuraSealGoodyear 's DuraSeal technology allows tires to be manufactured with a gel-like, solvent-free compound built into the inner liner. The DuraSeal system, says the company, instantly and consistently seals punctures up to 1/4 inch in the tread area, and the self-repair will last until the tire is retreaded. The system is designed to remain effective even after retreading. According to the company, DuraSeal adds about 5 to 7 pounds to the weight of a tire, provides excellent sealing efficiency at temperatures from minus 40F to 100F and does not affect a tire's operating temperature, high-speed performance, durability or rolling resistance. DuraSeal adds an approximate 12 percent price premium to the tire.
