Just two ounces of Goodyear Bicycle Tyre Sealant in a converted standard tyre or tubeless tyre can repair punctures up to 1/4" almost instantly to keep you rolling. Longer-lasting Goodyear Bicycle Tyre Sealant is formulated to stay liquid in tyres with even thin casings for up to seven months. Arid conditions require more frequent monitoring of sealant levels, but anti-freezing agents in our special formula allow Goodyear Bicycle Tyre Sealant to be used in temperatures as cold as -30° C. One quart will convert up to 16 tyres. Pre-measured and ready to apply to one bicycle tyre.
