Give over.... its not the tyres fault its the riders...some tyres wear faster than others as they are a softer stickier compound.... there is no excuse to let your tyre get anywhere near that condition.... takes 30 seconds to walk around yer bike before you ride it..if the tyre was getting anywhere near the tread bar limits it should have been changed n not ridden for another few 100 miles... its a fact bike tyres wear faster than car tyres.... I get around 3000 UK miles out of my rear n always change them as a pair.. if your looking for longer life from ya tyre buy a less powerful bike … makes my blood boil when people buy bikes then moan about tyre life.. n don't get me started on darksiders..oops I said it out loud didn't I
