Don't think many people realise that if you are involved in a road traffic accident and the vehicle is scrutinised which includes checking tyre pressures, an insurance company will try and wrangle out of paying up either as much or at all based on the vehicle being 'in an unroadworthy condition' due to incorrectly inflated tyres. Happened to someone I know when the accident was knock for knock. Remember the law is an ass and operates based on 'technicalities'.
