TIRES

Maximum tire pressure under any circumstances is 30 p.s.i. Equal tire pressure should be maintained on all tires. Check tire sidewalls for proper inflation.

When installing a tire to the rim, be certain rim is clean and free of rust. Lubricate both the tire and rim generously. Never inflate to over 30 p.s.i. to seat beads.

WARNING: Excessive pressure (over 30 p.s.i.) when seating beads may cause tire/ rim assembly to burst with force sufficient to cause serious injury.
