The MOT test can be a stressful and expensive time for drivers, but there’s a simple trick that can help you avoid unnecessary failures and fines
For many drivers, the MOT test can be a nerve-wracking and costly part of owning a car. However, there’s a simple, cheap trick that could help motorists dodge unnecessary MOT failures and penalties: the 50p coin tyre tread check.
Experts from Number1Plates have shed light on how this small action could save you a few quid and keep your vehicle within the law. Tyres are one of the most crucial safety features on any car.
In the UK, the legal minimum tread depth is 1.6mm across the central three-quarters of the tyre width. Driving on worn tyres not only heightens the risk of accidents, particularly in wet conditions, but can also result in an MOT failure, fines, or penalty points if inspected by the police.
“Many drivers underestimate how quickly tyre tread wears down,” a spokesperson from Number1Plates pointed out. “Even tyres that look okay at a glance can fall below the legal limit. A quick check can prevent expensive repairs or failed MOTs.”
The 50p coin method
The trick is straightforward and costs just 50p. By inserting a 50p coin into the tyre tread, drivers can get an immediate visual guide to tread depth:
- Pop the coin into the main grooves of the tyre
- If the tread doesn’t reach the inner rim of the coin, it’s below 1.6mm
This method is widely endorsed by motoring organisations and is a reliable, low-cost way to ensure your tyres meet legal standards without needing professional tools.
Number1Plates said: “The beauty of the 50p check is that it’s quick, easy and safe. Drivers can do it themselves in minutes, spotting worn tyres before they lead to MOT failures.”
The cost of ignoring tyre wear
Ignoring tyre wear can be a costly mistake. The price for failing an MOT due to worn tyres can range from £45 to £100, depending on the garage and the repairs required.
Moreover, driving on substandard tyres:
- Decreases braking performance, particularly on wet roads
- Heightens the risk of aquaplaning
- Could result in higher insurance premiums if you’re involved in an accident
“Tyres are not just a legal requirement-they are a safety issue,” Number1Plates emphasised. “A small investment of time and 50p can prevent hundreds of pounds in fines and repairs, not to mention the risk of accidents.”
Extra tips for drivers
In addition to the 50p trick, Number1Plates recommends regular checks:
- Inspect all four tyres – Tyres can wear unevenly, so check each one.
- Look for damage – Cracks, bulges, or cuts indicate you need a replacement.
- Check tyre pressure monthly – Underinflated tyres wear out faster and reduce fuel efficiency.
- Rotate tyres regularly – This ensures even wear and extends their lifespan.
- Consider age – Tyres older than 6 years may need replacing even if the tread appears fine.
Routine tyre inspections are a straightforward, budget-friendly approach to maintaining safety and legal compliance. The 50p coin technique is ideal for all motorists seeking a swift, dependable gauge of tread depth without requiring specialist tools.
The spokesperson said: “This little 50p check could save you money at MOT time, prevent fines, and most importantly, keep you safer on the road. It’s an easy habit that every driver should adopt – it only takes a minute, and the peace of mind is priceless.”
