I have gotten 20K miles on these tires over 3.5 years and am down to the wear bars in the middle. Some of this wear is due to running too high pressure and wearing the middle out somewhat prematurely. Tires performed very well, some corners that I've taken were impressive. Driving was mostly city and congested freeway, but have made several trips up to the mountains where I was able to have a little fun in the TLS. The tires have been pretty noisy on some surfaces for the last year. This is probably too much tire for my driving habits.
