I noticed noise coming from my tires recently. Mechanic said the tires are 'cupping', probably due to bad shocks. The tires are Michlen XC LT4. They were put on at 18000 miles (Firestone recall) and the car now has 65500 miles.
I have replaced the shocks with sensatracs. I also had front end aligned because the tires showed some wear on the edges.
I have noticed this same type of noise coming from other vehicles on the road.
I don't do any towing, just occasional boat launching.
Are the tires still safe? They still have fairly good tread and overall I am satisfied with the tires. But I still get tire noise on the road.
What, exactly, cause tires to 'cup'?
Thanks
