Mount the tire on the rim and pump it up first without sealant. In the next step, deflate the tire and remove the valve core. Fill the tire with the desired amount of sealant. Replace the valve core and pump up the tire. To distribute the sealant well inside the tire and rim, we advise you to take a short ride or rotate the tire. Have a good ride!
