Tyre Wear Signs You Shouldn’t Ignore

In this article we will discuss how important tyres are to road safety and point out signs of tyre wear that you should not ignore.
Badly Worn Tyre
Never let your tyres get to this point.

Tyres are incredibly important for effective road safety. However, as with anything, a tyre will begin to wear and the performance decline with time. To ignore signs of a tyre’s wear is dangerous and in extreme cases illegal.

To keep yourself aware of the condition of your tyres check them regularly. Remember to also listen out for any unusual noises when driving and to feel how they respond to the road. To help you out, the following list of 5 tyre wear signs you shouldn’t ignore has been put together.

1. Trouble with the Sidewall

The sidewall of a tyre is, quite simply, the side of your tyre. No shock there. A well constructed and strong sidewall is essential for a safe tyre. Look out for any signs of cracking or cutting. This could be caused by the tyre hitting the kerb when parking, continuous under-inflation or simply old age.

If you spot any early signs that the tyre is starting to crack around the sidewall then you will need to replace the tyres. Once these crack begin to grow, the integrity of the tyre is lessened and the chances of a blow out increase.

2. Uneven tread wear

As part of your on-going tyre maintenance checks, always have a look at how the tread is wearing. If you can see that across the tyre the rate of wear is taking place at different rates – i.e. sections are wearing faster than others – then you should take the car to your local mechanic.

Irregular wear on a set of tyres can be the result of incorrect air pressure in the tyres (either under or over inflated). However, there could be a mechanical issue such as misaligned wheels, damaged tyres, or problems with the suspension.

3.  Bulges on the tyre’s surface


Another indication that there is something wrong with the tyre is the appearance of bulges on the tyre’s surface. These will almost appear as blisters on the tyre’s surface and are a sign that something is seriously wrong with the reliability of the tyre.

If you spot a bulge on your tyre you should replace it immediately. At the point where the tyre is bulging, there will be an unseen weakness in the depths of the tyre. This could lead to a tyre failure at any time. This may be a cliché, but it’s definitely better to be safe than sorry.

4. Excessive shaking when driving

If you find that your tyres are causing unwarranted vibrations when you are driving this is a indication that there is something wrong with either your wheels or with the tyres. You will more than likely feel the vibrations through the steering wheel.

Possible causes for this kind of problem are wheel misalignment, unbalanced wheels, or even potentially bent wheels. Another possibility is internal tyre damage. Either way, have the car and wheels checked as soon as you can.

5. Tread worn too low

Tread depth is extremely important in providing a tyre with the appropriate amount of grip. The greater the depth of a tyre’s tread, the quicker it will stop when braking or hold its line when cornering. It is important to check the tread depth on a regular basis.

In the UK, the legal minimum tyre tread depth is 1.6mm across 75% of the circumference of the tyre. However, once a tyre’s tread depth drops below 3mm, the deterioration in performance will rapidly falter. If you measure the tread depth and it is below 3mm, seriously start looking around for a new replacement set from online retailers such as Blackcircles.com.
