I've presently have Goodyear all weather classic tires on my sedan. These have the period looking diamond tread bias ply. Although I run 16" wheels with 6.50 x 16 tires I have rotated tires and at about 9000 miles I need to replace two of them due to very little tread left. The wear is even across the width. Has anyone found this tire to have this lower life? I'm looking at other brands and have heard Firestone has been good. Anyone want to comment on your tire experience.? Recommendations ?
