I've still got one of Ron Haslam's ex race school rear tyres on the blade, been on it for ages, think it may have been to Spain twice and its still got the hot tear marks on the edges. Wearing well and will need replacement in a few months (prob. with another ex Haslam school tyre if I am honest) Not sure which track this was or the month BT023 These were me running in fast at Mallory Park in Mid November 2010 with trusty BT023's
