8. Unseat back tire bead. Use hydraulic tool. If insufficient clearance, use shorty ram between vehicle frame and back flange. (Photo 7) 9. Use boom truck and sling or tire handler to remove tire. 45 Stand clear when using a cable or chain sling. It can snap and lash out. 10. With assistance, remove back flange.
Demounting Tube-Type Off-The-Road Tires Read safety instructions (pages 26-35) before proceeding. Before moving any rim or wheel component: • Wear proper personal protective equipment (PPE). • Remove the valve core. • Exhaust all air from the tire. • Run a piece of wire through the stem to be sure it is not plugged. Exhaust air from both tires of a dual assembly before working on either. Inflation Procedures for Proper Mounting After Tire & Rim Assembly Has Been Placed on Machine During mounting, all off-the-road tires must be inflated, deflated, and reinflated. This procedure has two purposes. First, it helps assure that the beads are seated properly. Beads must seat against rim flanges and be in compression on tapered bead seats. Second, it removes buckles and uneven stress from flaps and tubes. Initial inflation varies with rim size: 46 1. Unseat beads as described for the size assembly involved. 2. Before removing tire from rim, be sure valve will clear gutter section. 3. Remove flap from tire. Use tool with a rounded end to pry out and away from beads. NOTE: If necessary, use a tire spreader to spread the beads. A small auto jack can be used as a spreader. 4. Remove the tube. Be careful not to pull on valve stem or enlarge any areas of damage. • Grader tires inflate to 50 PSI (3.50 Bar) • Less than 29” rim diameter tires inflate to 75 PSI (5.25 Bar) • Larger than 29” rim diameter tires inflate to 90 PSI (6.25 Bar) Failure to seat the beads can cause bead durability problems. In tubeless tires, it can also allow air leakage under the beads. Air pressure is the only positive method to fully seat off-the-road tire beads. Operating a tire will not seat an improperly mounted tire. It will result in damage to the beads and shortened tire life.
