Last June (6-21-2010) I had a set of those tires installed. Mileage then was 108,799. At 9-13-2011, I'm at 136,121. Miles so far: 27,322 and using a nickle (all I had) tread depth is at the neckline. So I might be able to make 50,000 considering I rotate them every 4-5 thousand miles.

 

Damn that's not bad at all.
