With all new cars now coming equipped with TPMS, uneven tyre wear as a result of under (or over) inflated tyres should theoretically become a thing of the past. That theory has yet to materialise in practice; the latest Department for Transport figures reveal that around 1,000 casualties are caused every year on the UK’s roads from tyre-related incidents. And perhaps the brave new world of tyre safety promised by required TPMS fitments may have been inspired by too much blue sky thinking anyway. With many drivers now relying on TPMS systems to advise them when to top up their tyres with air, it is possible that some are checking their tread depth even less frequently than before.
