Checking the Tread on Your Car Tyres
The law in Great Britain is very specific when it comes to car tyres. It’s such an important part of car maintenance to ensure that all car tyres are in good condition that to drive with defective car tyres carries a high penalty; currently a fine of £2,500 and a 3 penalty point endorsement per defective car tyres (that’s £5,000 and 6 points for 2 defective car tyres, and so on).
Many people are caught out every year for simply not knowing that they are breaking the law in relation to the condition of their car tyres – but ignorance is not an excuse. It won’t stop you from being involved in an accident and it won’t stop you from ending up with a hefty fine and penalty points on your licence. As set out in the Road Traffic Act 1988, as the driver of a vehicle it is your responsibility to make sure that it is roadworthy and you are liable to face legal action if you do not do so.
Worn or ‘bald’ car tyres are called so because the car tyres tread – which helps you to stop quickly in an emergency – has been worn down to an unacceptable level. Sometimes you can tell by looking that a vehicle has ‘bald’ car tyres, but on the other hand, it can be really hard to tell just by sight alone – especially if it’s a close call. However if you are stopped by a police officer and your tyre tread is found to be below the legal limit, which for cars in Europe (including the UK) is 1.6mm, then you will face punishment as laid out in the first paragraph of this article – so it’s really worth your while to check your car tyres regularly and make sure that they are road-worthy and safe.
How to Check Your Car Tyres Tread:
All passenger tyres have little bars moulded into the tread called ‘tread wear indicator bars’. They can be found in the tread grooves, near the bottom and in several locations on the car tyres. If you look for these bars and find that the car tyres is worn so that any of them are now lying flush with the tread ribs, then you need to replace your tyre as soon as you can. If you can’t tell, or want a professional opinion, just go to a repair garage, they’ll be happy to help you out and usually will do it for free.
Under-Inflated Car Tyres:
If there is wear on both edges of the car tyres, this means that it is likely that your car tyres are under inflated. This reduces the life of the car tyres because it wears away the outside edges of the car tyres and plays havoc with the car tyres durability because the edges get too hot. Having under-inflated tyres also makes your car work harder because it increases the rolling resistance and means you use more fuel than you should do. If you check your tyre pressure and all seems fine, then it might be that the vehicle is misaligned – you will need to take it to a garage to get checked out.
Over Inflated Car Tyres:
If there is excessive wear and tear in the centre of the car tyres, this usually means that the car tyres are overinflated as this makes the middle of the car tyres load bearing and therefore runs it down faster than the rest of it. Again, this will reduce the life of your car tyres and can lead to costly replacements, or worse, being involved in a tyre-related accident. Again, it could be a misalignment issue so if the car tyres pressure is ok, get professional advice.
Worn Areas on the Car Tyres Tread:
Sometimes known as scalloping, dipping or cupping, dips in the tread are usually found on the front car tyres, and are a sign that the wheels may not be balanced correctly, or that the steering and suspension systems need to be checked out.
Unbalanced Car Tyres:
Unbalanced car tyres can lead to problems with not only a vehicle’s suspension system and car tyres, but also to the driver as the constant vibration can lead to fatigue. If you feel any vibration while driving, have your tyre balance checked out as soon as you can.
If You Find a Problem:
If you do find a problem with your car tyres – even a puncture, don’t panic! It might be possible to save the car tyresbut you must go to a professional tyre fitter so that they can measure the damage and make sure that it is within the legal guidelines for repairing and replacing car tyres.
