Wheels 1

“After owning the car for 3 years and putting a little under 50K miles on the vehicle, I have had to change my tires twice now because the inner tread would go bald after 20k miles or so. I had to alignment checked and the dealership said it was within spec. I have kept up with the tire rotations as well and the suspension and shocks are working as well. I believe the problem is that the camber/toe in and toe out specs are too wide that it allows for the tires to wear unevenly.”
