1. Uneven wear between tires
Uneven wear doesn’t mean an irregular pattern throughout the tread of one tire, instead it means that when the front tires wear faster than the rear ones. If you notice this happening with your tires, they need to be rotated as soon as possible. The wear difference will soon become insignificant if the tires aren’t worn out completely. However, you may also notice an irregular wear pattern on one of your front tires, where one side has less tread than another. If the tread wear isn’t too severe, the tire can be rotated, but if it is, it’s better to change the item.
