I've been using AZ Auto Trends for years. They are my ship-to shop for orders from Tirerack.com, their prices for installs are unbeatable, and they go the extra yard to make sure it's perfect. They are also a great shop for dealing with imbalance problems with wide/low-profile tires, as they have a road-force balancer that enables them to simulate road conditions during balancing. I've sent other friends to them and they have been equally satisfied. I was bummed when they moved to Scottsdale, but hey, I moved to Scottsdale and now I can use them again. Highly recommended.
