The idea is that you have a puncture, computer tells you that tyre is
deflated, no big drama, you stop and replace it with spare one.
In that case run-flat can be repaired.

In emergency, if you continue driving, tyre will not
disintegrate due to heat but kevlar sidewall will be
damaged and you must get new tyre.
