General maintenance methods are: repair or replace the balance beam, remember that the balance beam must be refueled regularly; Check and supplement the tire pressure; Check whether the riding bolt of the spring bow plate is loose and whether the central bolt of the bow plate is broken.
The problem of air pressure is that the tire pressure is too high, and the middle part of the tire crown wears faster, or because of insufficient air pressure, the inner and outer parts of the tire crown wear faster. Due to the different air pressure between the left and right tires, low air pressure leads to faster wear.
First of all, four-wheel alignment problems are generally related to camber, front toe-in, kingpin camber and camber cancellation.
The problem with tire grades is that tires of the same type and different grades wear faster at the top, leading to eccentric wear.
When the tire is seriously worn inside and outside, it may be because the four-wheel alignment data is inaccurate, and this situation needs to be repaired. Four-wheel alignment is not accurate: the four tires of the moving vehicle are not on the standard horizontal and vertical straight lines, so the two wheels on the same side will be eccentric when driving. Or because the vehicle is not driving in a straight line, the vehicle automatically corrects the deviation, resulting in uneven friction and eccentric wear between the tire and the ground.
