Karen took her car in as she had a low tire that needed a patch. The Costco rep said a nail went in the side of a 1 yr old tire. and the tire was not repairable. He wanted to sell us a new set of tire and the others were almost new. We went to Rim to Rim, and they said it was not in the side of the tire and repaired it. Their prices are extremely competitive, wide choice of tires, and great service. They are my choice now. But easy for me as I live in Okotoks. It is always worth a phone call. Always smart to do your research.
