Good Products, Great Price, Excellent Service

Shipping was great , everything went well , except the letters (Goodyear) where rubbed of and that's why I wanted them to match my rear tires . Maybe if you wrapped them so they didn't rub during shipping . I have a dragster that I take to car shows and perfection is looked at . Either someone returned them or shipping was really rough on them

Muy bueno

Quick and easy, what more can I ask for? And all at a great price.
