Just two ounces (59ml) of Stan's Tire Sealant in a converted standard tire or a tubeless tire can seal holes up to a 1/4" instantly. One pint will convert up to 8 tires.
Stan's Tire Sealant will stay liquid in a mountain bike tire with a thin casing for two to seven months on average. Riding in arid climates or storing the bike in a hot area will require more frequent monitoring of sealant levels. Special anti-freeze agents allow the sealant to be used in environments as cold as -30°C.
