We bought used tires for our Mazda Truck at daniela's tire shop, Once we got home we notice the tires were not the right size or for our model truck. On the tire it says for TRAILER SERVICE ONLY, This means they are not safe to have on for cars or trucks! We confirm this info on Goodyear .com the website informs us they are not safe for regular vehicles only for trailers, boats or fithwheels . We contacted the shop to let them know what we had discovered; they were very rude and showed no concern about their mistake. They laughed telling us that there was nothing we can do and threaten us to shot us if we would go back. They dont know what they are doing and they should be shut down and not allowed to manage a tire shop. As a business they should have great customer service and be polite and know whats safe or not! THEY ARE CROOCKS AND LIARS!!
