Most out of tire alignment issues are found after damage has already been done. Only a few truck fleets perform regular alignments on their tractors and trailers. A truck’s tires will tell a driver whether or not the vehicle is running straight. Many tire problems can be traced back to mechanical conditions on the vehicle and not necessarily obvious ones.
Vehicle misalignment often shows up as irregular wear conditions on steer tires. Drive tires can show the same sort of wear as steer tires if not aligned correctly.
Fred Staugh, vice president of maintenance at CRST recommends tires should be examined at every PM interval for these tire signs of alignment-related wear, such as feathering or excessive wear.
