I've been using Willie's for ten years except last December when he having surgery. Willie was always $70, but I didn't know how long he was going to be closed, so I called Todd Casey because of all the recommendations on TOTV, but he charged $112. I guess Todd doesn't need to be competitive, I think TV only charges $70 and Tire Choice is $60.
That's right, you can also go to Tire Choice at Colony Shopping Center, I used them once about five years ago when Willie wasn't available, and they were $50, I think they are now $60. No appointment necessary, just drive your cart in and it will be ready in about an hour.
