2002 Kia Rio uneven wear

Have you been rotating the tire's regularly?If so did you rotate them just front to back?The tire's stayed on the side you put them on the entire time they were were on the car?

The tires are rotated about every other oil change. They are changed, to my knowledge, in the "x" formation. Thank you for replying to my question.

The best way to explain the one side wearing down a little faster then the other is your car has what's called a driven wheel where it does most of the work and wear's the one side down faster then the other.Same thing happens on rear wheel drive car's or truck's unless they have limited slip.So another word's it would be normal for your car.As long as the wear is even all the way across your fine.

Thank you so much for your response. It is a strange situation, I never rotated tires before, and when I do - this happens!

Your welcome It's not strange just common when you rotate your tire's from front to back.

Thank you, I understand, the tires were not rotated in the "x" pattern as I was told.
