What is your question?
On my 2003 aviator,I have 33K on my tires and hear tires moise on a smooth road which I never heard before. They tell me I have tire cupping. I have two questions: 1) How does this occur when I regularly align my wheels and balance my tires? 2) Is it safe to drive with cupped tires that have plenty of tread remaining?
Thanks...the guy at Firestone checked my suspension and said it was OK. He also felt the tires and said it was safe. I think I will change brands the next time I buy tires.
