Though not a major area of focus in , there are many safety precautions to be observed when handling while on the wheel. In fact, the handling or rules are almost like rules for . Meanwhile in a highlighted format, there are safety precautions expected when dealing with the wheels:
- Do not mix radial, bias ply, and belted bias on the same except in emergencies.
- Normally install a new during repairs on the same axle replacing only one at a time and pair it with the texture having the most tread.
- Always follow the manufacturers’ pressure recommendation. Radial appear to be under-inflated in comparison with bias ply or belted at the same inflation pressure.
- Generally, rotate radial from front to rear and from rear to front. However,, certain manufacturers give optional diagonal rotation plan for radial specification.
- Although tread may differ or seem the same, are built by different manufacturers with identical T.P.C. specification.
- To tight wheels, tighten all lug nuts, then loosen each side as hard as possible. Or start and rock from drive to reverse, allowing to move several feet each way before applying brakes hard. Never use heat to loosen tight wheels.
- Replace faulty wheels with new ones equivalent to original equipment wheels for load capacity, diameter, rim width, offset, and mounting configuration.
- Tighten wheel nuts in sequence and to proper torque to avoid bending wheel or brake drum or rotor.
- Follow equipment manufacturer’s instruction for checking wheel and assembly balance and to ensure maximum life.
THE CAUSES OF WEARS ON AND THEIR TYPES
Excessive or uneven tread wear results from underinflation, rapid stops, fast acceleration, misalignment, and/or unbalanced conditions. Road surface condition also affects life. Gravel roads and rough finished concrete will wear quickly. Smooth concrete and asphalt surfaces help in promoting maximum life. Normal wearing condition causes the tread to be reduced evenly and smoothly.
There are many types of wears peculiar with , however, these few highlighted below seem to be the most frequent occurring in :
- Spotty wear: this wear pattern usually results from a combination of conditions, including the design of the particular tread. Under inflation and incorrect camber are the main factors, along with excessive term or foe-out.
- Over inflation: this causes to wear excessively at the center of the tread surface. In addition, there are usually a little wear on the outer edges of the . This causes early failure at the center ribs and breaks in the sidewall.
- Under inflation: is characterized by excessive wear on the two tread ribs aadjacent to the inner and outer shoulder ribs. In many cases, under inflation also causes spotty wear.
- Toe-in and toe-out wear: the amount of toe-in and foe-out is one of the most importanat factors governing wear. Unless toe-in is correct, the will have a scrubbing action on the road surface, and excessive wear will result. Excessive foe-in produces a feather-edge on the inner edges of the tread ribs, which can be felt by reverse. The feather-edge is produced on the outer-edges of the tread rib.
- Camber wear: excessive camber will produce wear on one side of the thread. If there is too much positive camber, the thread wear will be on the outer ribs. If camber is negative, the wear will occur on the inner side of the thread. If there is excessive wear on both inner and outer areas of the thread. It probably was caused by excessive skidding on turns.
- Cornering wear: when considering any tire thread wear condition and what caused it, remember that excessive or uneven wear usually results from a combination of conditions. Tires wear at different rate on all four wheels due to driving conditions, weight of vehicle, power on the driving wheels, crown of the road, alignment of wheels, overloading the vehicles, tire inflation and probably most important of all, driving habits of the person behind the steering wheel. Since, fast starts, quick stops, high speeds and fast turns, etc. do take their role in the overall life of the tire. Therefore, conservative driving habits promote maximum life of the tire and decrease expenses of the overall vehicle maintenance.
