Toe in happens when a vehicle’s wheels shift inward. The term “toe in” describes the alignment position of a vehicle’s tires. Toe in happens when a vehicle’s front or rear wheels are turned inward with the front edges facing each other. Most vehicles are aligned to toe in slightly for better drivability; however, excessive toe in will cause problems, including excessive tire wear and poor handling. Various factors can cause a tire to toe in excessively.
Hitting a pot hole can knock a vehicle’s tires off course, causing the tires to toe in to re-establish balance. If the pot hole is very deep, permanent alignment damage may cause the tires to begin severely turning inward.
