Tire Mounting and Dismounting

Use a tire changing machine to mount or dismount tires. Follow the equipment manufacturer's instructions. Do not use hand tools or tire irons to change tires as they may damage the tire beads or wheel rim.

Wheel rim bead seats should be cleaned with a wire brush or coarse steel wool to remove lubricants old rubber and light rust. Before mounting a tire, the bead area should be well lubricated with an approved tire lubricant.

After mounting, inflate the tire to 220 kPa (32 psi) so that beads are completely seated. Install valve core and inflate to proper pressure.

WARNING: To avoid serious personal injury, do not stand over tire when inflating. Bead may break when it snaps over safety hump. Do not exceed 220 kPa (32 psi) pressure when inflating any tire if beads are not seated. If 220 kPa (32 psi) pressure will not seat beads, deflate, relubricate the beads and reinflate. Overinflation may cause the bead to break and cause serious personal injury.
