Tirerack.com has a "price pledge plus" list of local installers who "promise" to install for the prices listed on the tirerack.com website. Has anyone ordered tires through them AND used a recommended installer? A local one near me lists mount & balance for any 60-series or higher tire for $14.50 per tire. Seems like a good deal, I just want to be sure I don't get a run-around.
