Tire Mounting and Dismounting
Use a tire changing machine to mount or dismount tires. Follow
equipment manufacturer's instructions. Do not use hand tools or
tire irons alone to change tires as they may damage tire beads or
wheel rim.
Rim bead seats should be cleaned with a wire brush or coarse steel
wool to remove lubricants, old rubber and light rust. Before mounting
or dismounting a tire, bead area should be well lubricated with
approved tire lubricant.
After mounting, inflate to specified pressure shown on tire infor-
mation placard so that beads are completely seated.
WARNING:
Do not stand over tire when inflating. Bead may break
when bead snaps over rim's safety hump and cause seri-
ous personal injury.
Do not exceed specified pressure when inflating. If spec-
ified pressure will not seat beads, deflate, re-lubricate
and reinflate.
Over inflation may cause bead to break and cause seri-
ous personal injury.
Install valve core and inflate to proper pressure.
Tire Repair
There are many different materials and techniques on the market
to repair tires. As not all of these work on all types of tires, tire
manufacturers have published detailed instructions on how and
when to repair tires. These instructions can be obtained from
each tire manufacturer.
Balancing Wheels
There are two types of wheel and tire balance: static and
dynamic.
Static balance, as shown in left figure, is the equal distribution of
weight around the wheel. Wheels that are statically unbalanced
cause a bouncing action called tramp. This condition will eventu-
ally cause uneven tire wear.
1. Heavy spot wheel tramp
2. Add balance weights here.
3. C/L of spindle
