Sorry to read that Phil. I agree re the lack of spares on modern cars being a risk.
I have had a puncture a couple of times in the Mog's and have used the "we come to you" mobile services. They don't always have the exact tyres to hand but usually have the ability to do a simple puncture on the van or spec replacement. They have been pretty quick, faster than the AA.
At the last tyre replacement I retained the best older one from the front and rears (different sizes) as emergency tyres. If they cannot get a spare and I am near home I can get the spare run out to me by a friend. They can fit that as an enabler then I can get it sorted without the pressure. They usually have a £100 call out +tyre/puncture charge.
