so i took my car to put my summer tires on and the guy at discount tire told me that both of my front tires are worn bad due to weak suspension. my car only has 74,000 miles on it could my socks be bad? what should i look for up front to be worn out b.t.w the car tracks straight as an arrow doing 80mhp. when i got the car the rims where a little bent and i had them straightened., the tries have 45000~ miles on them. when you run your hand on the tire they feel like a wave just on the inside of the tire. could some one please explain in detail how bad suspension can wear tires ? thanks
