Lubricate the rim flange and tire bead. Use 5P3975 Rubber Lubricant or equivalent. 4. With the valve up and starting at the valve, pry the bead over the rim flange. 5. Continue around the rim until the top bead is completely over the rim flange. 6. Turn the tire and rim over. Lubricate the tire bead and rim flange. 7. Raise the rim and position the bead into the recessed area of the rim. Insert a lever and push down to raise the rim out of the tire.8. Check the rim for any damage.Mounting the tire
