After thirteen years and over 200,000 miles of driving, I had my first blow-out this morning, whilst hurtling eastbound on the A64 on our way to church:

Probably not repairable

I was considering swapping it for the spare by myself (it's only a few months since my last puncture so I'm an old hand at the task) but was persuaded by Joce to call the AA and let them get their hands dirty (after all, I was wearing my best suit..)

Some advice what to do it it happens to you.
