What is the reason why the two front wheels eat the tires inside?

The reason why the two front wheels eat the inner tires is that the four wheels are not positioned correctly, which leads to the four tires not being in two straight lines in the horizontal and vertical directions required by the standard, which leads to the inaccurate toe-in adjustment, the steering gear failure, the uneven cross beam of the car body and the large air pressure difference between the tires. Carry out four-wheel alignment: the front wheel is slightly tilted inward, and the angle is similar to the inside picture. If the angle is too large or the adjustment is not good, there will be fetal eating. This needs to be solved by four-wheel positioning. It should also be noted that when repairing or replacing the suspension system, four-wheel alignment is needed to prevent the car from biting the tire. Adjust the tire pressure: too high tire pressure will not only affect the ride comfort, but also lead to eating tires halfway; If the tire pressure is too low, it will damage the tire, even damage the wheel hub, and eat both sides of the tire. This needs to be adjusted according to the tire pressure value recommended by the manufacturer. In addition, in order to reduce the phenomenon of eating tires caused by abnormal tire pressure, the tire pressure should be checked at least once a month. Replace old tires: When the tires are seriously worn, only one or two tires need to be replaced, which will make the friction of the four tires different and lead to eating tires. Under normal circumstances, four tires are used all year round and need to be replaced at the same time.
