While modern tires are engineered to be incredibly tough and withstand extreme temperatures and pressures, premature failure can occur when tires aren’t properly maintained. Not only can this create a dangerous environment for machine operators, it can increase costs by forcing machine owners to purchase new tires more often than what is necessary. By taking some time to understand tire care, the life of your tires can be extended.
These factors can contribute to premature tire failure:
Tire Use – How aggressively are you driving? For some industrial vehicles, this may not be applicable; however, for automobiles, semi trailers and forklifts, the way you drive can protect your tires. Avoid hard turns and aggressive starts and stops that can peel away a lot of tread wear.
Low tire pressure – Under inflated tires flex a great deal during rotation, building up heat. Flexion and heat lead to premature breakdown of the rubber. Under inflation also results in uneven tread wear.
High tire pressure – Over inflation will result in the center of the tread bulging outward. Premature center wear can develop.
Tire Preventive Maintenance
Make sure to rotate tires based on the manufacturer’s recommendations. The more evenly you can wear out the tire, the longer they last. Check your tires for:
Cracks – Indicates that the tire rubber is degrading from oxidation.
Bulges – Indicates that the reinforcement belting has broken inside the tire.
Chips/Gouges – This is an area of weakness that could give out when the tire is placed under high work loading or pressures.
Tread Wear – Most tires have tread indicators, or wear bars, at intervals between the treads. When the tread is level with the indicator then it’s time to replace the tires. Look for uneven wear. This could mean that the tire is under or over inflated. It could also indicate that the vehicle requires an alignment.
Tire Pressure – Tires lose air through permeation. On average, a tire will lose one or two pounds of air per month in cool weather, and more during the warmer months. Tire pressure should be checked when cold. Manufacturer pressure recommendations are set on cold tires.
