Stop & Go International is a tire repair brand based in the United States that has marketed mushroom-plug tire repair systems since 1980 per their product packaging. The defining feature of the Stop & Go system is a one-piece molded mushroom plug installed from the outside of the tire using a spring-loaded pistol-grip plugger tool — the brand markets this as quicker, cleaner, and producing a better seal than rope/string plug kits because the mushroom cap seats against the inner tire wall. Stop & Go kits are aimed at the motorcycle, ATV, and powersports markets in particular, where small-volume tubeless tires are common; the kits also work on passenger car tires within the plug's size range.
