0 Self Healing Goodyear Tires

"Self-healing "DuraSeal" tires, which instantly seal themselves with little or no loss of air pressure, are now available from Goodyear Tire & Rubber. The "revolutionary" feature seals punctures up to ¼ inch in diameter and avoids flats, the company's executives said." - Construction Equipment

"The tires have a gel-like, nonflammable, solvent-free rubber compound built into the tire’s inner liner. The gel flows into voids and around objects less than 0.25 in. in diameter, and will do this repeatedly, letting it take care of dozens of punctures. The repair gel’s yellow color highlights punctures, making them easier to see. The tires also feature four all-steel belts, which gives the tires a solid foundation for several retreadings." - Machine Design

"DuraSeal is initially available in Goodyear's new G287 and G288 on/off-highway tires, and will be available later in other commercial truck models. Cohn said it probably won't expand to consumer tires because "there it's price, price, price, and they (most motorists) wouldn't pay for it." - Construction Equipment
