I've always kept a Stop 'n Go mushroom plug kit on board my moto. I've used it only once on the road and it saved my bacon, as I was 2500 miles from home and 50 miles from a stealer to replace the tire. Yup, I did replace the tire, 'cause that what everyone said I should do. In other words, repaired tires are dangerous tires. But are they? My truck just picked up a good size wood screw in its casing, just under the cap of the tire. I grabbed the old Stop "n Go and plugged it with a mushroom plug. One knowledgeable "wrench" said I'm good to go for ever and ever, and another said, the steel mesh in the tire will eventually cut the plug in two, causing the tire to spit the plug out and go flat again. So, which is it. Door No.1 or Door No.2? We shall see because I'm not buying a new tire for my truck until I have to. Bob "Flylooper" Burns COG #5887 E Clampus Vitus, YB#1 '04 FJR 1300
