Thanks Cuppa. I run about that diameter, 275/65x17 and 265/70x17 I think, I have 2 sets of rims.

I carry a 2nd spare on remote trips which I store on the roof. That seems to get heavier each year. Thinking of getting a 6" rim and putting a 235/85x16 tyre on it so it's a bit lighter & easier to throw on the roof. Could even do that on the rear door as well come to think about it.

I've had so few punctures in my life, not just off road but everywhere, all up.

How have you gone with punctures Cuppa with all your travelling?
