Tyre handling and safety tips

In Knowing Your Retreads, October 20222 MinutesBy NZ Trucking magazineNovember 8, 2022

Vipal Rubber presents valuable information to help you get the most from your tyres. This month – the handling and storage of tyres.

Mounting and dismounting truck tyres

• Place axle stands under the truck to ensure operational safety for removing the wheel assemblies.

• Release the tyre air pressure before removing the wheels from the vehicle.

• Use a water-based lubricant on the tyre beads for mounting/dismounting.

• Remove moisture from inside the tyre before mounting it. This will avoid rim and valve damage.

• Drain the moisture from the air-compressor receiver regularly.

• Use a certified ‘safety cage’ to inflate the tyre.

• The workplace area must have rubber tyre-changing mats.

• Match the same type of tyre and running tread pattern across the front axle.

• Match the same type of tyre and drive tread pattern across the rear axles.

• Do not exceed 2mm of height between dual wheels – the tallest tyre must be mounted on the outside position.

• The wheel must be clean and free of oxidation, cracks and deformities, which can cause damage to the tyre.

• If the fleet requires you to mark or brand the side wall of the tyre, we recommend the mark or brand be placed adjacent to the valve during the fitting process. This process facilitates quicker and easier inspection and tracking of tyres.

• Where possible, every wheel should be balanced after the tyre-fitting process is complete.

Storing tyres

• Keep tyres away from electric motors, battery chargers, and welding equipment.

• Store tyres in a sheltered area that is dry and well-ventilated, and away from direct sunlight.

• The storage area should be paved and clean, with no grease, oil, solvents or petrol.

• Keep a fire extinguisher nearby.

• Where possible, store tyres vertically on a rack or shelf. If not possible, do not stack more than eight truck tyres on top of each other. Turn the tyres over every three months.

• Remember to rotate the tyres in your stock holdings – first in, first out.
