There are many factors may trigger the occurrence of irregular wear. Among those, mechanical malfunctions of vehicles such as misalignment and uniformity of the tire and wheel assembly are the major factors.

Tire and wheel imbalance may result in irregular tire wear. Steering axle and drive axle tires should be balanced dynamically for best results. Vibration may also be the result of mismatch of the high and low spots of the tire and wheel. To resolve vibration problems, the runout of tire and rim should be measured.

Wheel weights are used to balance wheels. Wheel weights come in a wide variety of sizes. They also come in many different shapes. The different shapes accommodate the different wheels they must fit. Using the improper weight will normally result in the weight coming off the wheel and a need for re-balance.

A properly done wheel balance will last the life of the tire unless the tire must be removed from the wheel, or the wheel or tire is altered. Tires wear evenly around their circumference, so wear will not affect balance. If the proper weights are used and they are properly installed, will not come off.

Many other factors can and do cause vibration like wheel balance. It is important to remember that round and balanced are two different things. For instance, an out of round tire. An out of round tire can be balanced. A square block could also be balanced, but it will also not roll without vibration.

Every piece of tire out from Paxxon has been tested following the A TMC recommended practice (RP) which is a specification or practice that assists equipment users, vehicle/component manufacturers and other industry suppliers in the purchase, design, maintenance and performance of commercial vehicle equipment. Current Technology Maintenance Council limits from RP 214B Tire/Wheel End Balance and Runout section.

Warning: Serious injury or death may result from a tire failure. Many tire failures are preceded by vibration, bumps, bulges or other anomalies. If an unusual vibration occurs while driving your vehicle or you notice a bump, bulge, or an anomaly not associated with normal tire performance, have your tires and vehicle evaluated by a qualified service person.
