It's a common temptation: the tyres are a bit low on tread, but they'll last a bit longer, right? The reality is that delaying a tyre replacement when tread is approaching the legal limit exposes you to serious safety risks, significant legal penalties, and potentially far greater financial costs than the price of the new tyres themselves.
The Safety Impact Is Stark
TyreSafe, the UK tyre safety charity, has published data showing that at 50mph in wet conditions, a car with tyres at 1.6mm tread (the legal minimum) needs an average of 11 metres more to stop than one with 3mm tread. At motorway speeds, that gap widens further. In an emergency stop, those extra metres can be the difference between avoiding a collision and being involved in one. Worn tyres also have reduced resistance to aquaplaning — the terrifying sensation of the tyre skating across a surface of water rather than maintaining road contact.
The Legal Penalties Are Severe
A tyre below the legal minimum tread depth of 1.6mm is a fixed penalty offence. Each illegal tyre can attract a fine of up to £2,500 and three penalty points on your licence. With four illegal tyres, you could be facing a £10,000 fine and twelve penalty points — enough to lose your licence entirely. Beyond the fine, if you're involved in an accident with illegal tyres, your insurance company may refuse to pay out, leaving you personally liable for all costs.
MOT Failure and Increased Running Costs
A tyre at or below the legal minimum will cause an automatic MOT failure — resulting in the cost of a retest on top of the tyre replacement. Worn or under-inflated tyres also increase rolling resistance, meaning your engine works harder and fuel consumption rises. New tyres with correct pressures often pay back part of their cost through improved fuel economy over time.
