Not to mention burst tyres. I came across a woman on a lonely
country road who had a blowout. I changed the tyre for her and
decided to check the pressure in the others - found that to
be around 70 PSI.

She had checked the pressure earlier in the day, and had filled
the tyres "until the hose stopped hissing".

I believe that the insurers may well fight a payout if it can be shown
that incorrect tyre pressures contributed to an accident.

I find that amazing, considering that tyre shops often put in wrong tyre
pressures. They just look up the car model; not considering that each model
can be specified with different wheel/tyres. Hence low profile tyres often
get to little pressure.

Last puncture repair I had at KwikFit, I realised soon after, because
of the unbelievably skittish ride, that the tyre had been inflated to
about 60psi (routine, I think, for leak checks) but not deflated to
the correct pressure.
