I will second this on the Stones. Got 11,600 from stock rear tire, not carefully monitoring tire pressure (checked it once a month or so). I am currently at 13,000+ on the replacement Stone, and still not quite even with the wear bars. I was much more attentive to tire pressure maintenance with this one.
