Poor handling while driving is due to a number of factors, all of which usually point to you needing new tires. Uneven tread wear, the wrong size of tire, treads that are too low, and improperly inflated tires are all reasons why your vehicle may not handle as well as you want. Damaged tires or rims from hitting curbs or potholes and misaligned tires are a couple of other factors that can negatively affect your car’s handling.
