Flat Tyre question post SHTF

[Lightspeed]

This is more serious that it at first appears.

OK so we all have spare tyres in our cars.

What do you in a world where you are on your own if you get two punctures and there's no kwikfit type support any more?

Options are Fix it yourself, or steal good wheels and tyres from someone else.

Ultimately, we need to know how to fix tyres ourselves.

Devonian: Would you be so kind as to describe how you 4x4 boys get tubeless tyres off their rims, what you use to repair them and how you get them back on the rims again?

The last 4x4 tyre I changed on my own was on an 88" landy.... but that was steel rims and tubed tyres.

Are tubes still available in modern LR rim sizes???
