We had a flat on I-70, and initially stopped at another local tire shop. They didn't have the tire we needed, and referred us to Precision Collision. Dana immediately discovered that our big-chain tire shop had mounted two of our tires backwards, which likely caused our separation. He found us a good, used tire, and flipped our other backward tire around. He torqued our lug nuts, and replaced the four nuts the big-chain had left off. Highly recommend.
