Do & Don'ts of Tyre Handling


Tyre Handling / Transporting tires

Off-The Road tires are very heavy, poor handling of an unfitted tire can cause serious injury. When transporting tire, particular care must be taken to ensure that the beads & inner of the tire are not damaged. Even a minor damage on bead or inner liner will result in premature failure due to air seeping into the body of the tire causing a separation. In order to eliminate the risk of damage at the bead area and other problems which could result due improper handling, we strongly advise that –

The tire is not lifted on the bead with a crane hook.

Flat straps ( wide fiber / rubber sling or belts ) to be used.



Do not use ropes, steel slings or chains.

The tire is lifted under the tread and not on the beads when a fork lift is used.



Storage

In order to avoid premature ageing and damage to tires, they should be stored in a cool dry place indoors and away from direct sunlight, electric motors, oil, fuels, grease, lubricants & other volatile substances.

If this cannot be done, the tires must be covered with a waterproof tarpaulin to protect from Ozone sources, Ultra-violet rays & weather. tires should be stored vertically on the roll, one against the other.

Avoid stacking one over the other. Tubes, flaps & O-rings may be stocked in their original packing or unwrapped on racks / shelves – never suspended.

When storing tires fitted on rims, reduce inflation pressure.



Do's


Use proper rim size for recommended load/speed & inflation pressure.

Check inflation pressure at required intervals. Maintain the correct inflation pressure at all times.

If the tire is new, compensate the inflation pressure for growth of the tire.

Rim should be checked for any leakage during inflation.

Never mount 16" tire on 16.1" rim

When seating the beads, never inflate the tire beyond 35 psi OR 2.5 bar.

If operating pressure is less than 35 psi OR 2.5 bar, first inflate the tire with 35 psi to allow the bead to take its proper position on the rim and then de flate to operating pressure.

If operating pressure is more than 35 psi OR 2.5 bar, first inflate the tire with 35 psi to allow the bead to take its proper position on the rim and then inflate further to get operating pressure.

Before inflating the tire ensure that tire is centered on the rim.

Inflate the tire after keeping the assembly in the cage.

Always inspect inside of tire for loose cord, Cuts, Penetrating objects or other casing damage.

Always replace a tire with one having the same rim diameter designation and suffix letters. e.g.10.5/65-16 ,10.5-16

Check for leakage of air from rim parts, lock/flange ring o- ring.

Use vegetable oils, soaps for flanges & o- ring while mounting the tire for proper bead seating.

Always inspect valve cores for proper air retention. replace damaged or leaky cores.

Tube valve should be covered with cap to prevent penetration of dirt.

Always use sealing valve caps to prevent loss of air.

For tractor drive wheels, for on road jobs, maintain minimum pressure of 1.4 bar.

For tractor drive wheel tires, for field work, never lower pressure below 1.1 bar. Always use new tube with a new tire.See the direction of rotation while mounting a tire, in case of directional tire.

Don'ts


Never use damaged tire, if used would cause soil / small stones along with the water enter the cut portion & damage the carcass leading to tread separation.

Avoid/spinning of tire subjected to muddy terrain with stones it falls prey to severe cuts.

Never re-use the same o- ring while remounting the tire.

Never use tube type tire as tube less.

Never lower inflation pressure by bleeding as it increases heat built up.

Never reinflate a tire that has been operated in run-flat or underinflated condition. Demount and inspect the tire and all rim parts before refilling.

Never use any rim part that is bent, having dents, pitted form corrosion, cracked or worn.

Remove rust, dirt or any foreign material from rim parts.

Never try to make up for larger differences by changing the inflation pressure.

Never use petroleum based lubricant.
