Flat Tyre question post SHTF

[Devonian]

The other method of breaking the seal between the tyre and rim is to us a hi-lift (or farm) jack like:

I guess most people won't have a hi-lift jack, but in a SHTF Situation, I can't see why the same principle could not be adopted using a bottle jack if you can find something at the right level to jack off of (that really doesn't sound right does it!!).

But with the repair kit, you don't need to remove the tyre anyway.
