Tire Markings


1. Always follow the tire recommended air inflation pressure:

 a. an under-inflated tire causes the tire to be heavily overloaded causing the carcass to degrade in quality which weakens the casing strength that can lead to tire blow-out upon impact during service.

 b. an under-inflated tire increases the rolling resistance of the tire causing tread to shoulder separation. An increase in rolling resistance increases fuel consumption while greatly reduces the tread life of the tire.

 c. based on the study by Avon Tires of Britain, a 10% under-inflation translates to 15% reduction in the life expectancy of the tire and 2.5% increase in fuel consumption.


 a. The Storeroom temperature should be below 25°C. It should preferably be dark.

 b. Extreme humid conditions should be avoided. Condensation occurs on the tires. Tire must not be stored in condition where they are exposed to rain, splashes, etc.

 c. Tires must be protected from light, particularly direct sunlight and intense artificial light with high ultraviolet content.

 d. Ozone has a very strong deteriorating effect on tires.  The storeroom must not contain any zone producing equipment, such as fluorescent lamps or mercury vapour lamps, high voltage electrical equipment, electric motors or any other electrical equipment that may generate sparks or silent electri discharges.

 e. If possible, tires must stored freely in their natural form, so that they are not under stress, pressure or torsion.

 f. Solvents, Oils, Greases, Heat – Tires must be particularly protected from any contact with solvents, oils or greases.

 g. When handling tires in warehouse, don’t drop tires higher than 3 feet to prevent kinked bead.
