Check your tyres fellow BRMers. I've had a very close call on the weekend with a high speed blowout. Plenty of tread left on the tyre but has been on the wheel for many years. Big noise, close to total loss of control but just managed keep things pointing in the right direction. Just glad that no-one got hurt and my trusty chariot is unharmed. Could have been nasty if there was another vehicle nearby. My own fault and a bit of a wakeup call. Check your old rubber and be careful - don't want anyone to have a near miss.... or worse.
