I was told by the madison BMW dealer that on my BMW Z3 both my rear tires were "fail status" and the two front tire were "caution." I took the car to Toms , had him order the tires which would have been over $800 installed, the BMW dealer's price was over $1000, and they told me there was nothing wrong with the tires and I didn't need new tires. You have to really appreciate the honesty of this business. They easily could have replaced the tires and I wouldn't have known any better.
