I've always gone to Discount Tire for our tire needs. They are always helpful and they complete the job quickly. I like dealing with them because I never feel pressured like with some mechanics. The prices and information are straightforward and you don't have to haggle about what's wrong with the tire, etc. It's all very cut and dry. Also, their warranties are great. I always purchase the extra warranty certificates, and it's always been worth it. They cover the life of the tire and are great about replacing them in a timely manner if anything goes wrong.
