When should you change my tyres?

When should I change my tyres?

Tyres are an extremely important part of your car – being the only section in contact with the road and carrying the entire weight of your vehicle. 

For this reason, ensuring that you are running on safe and maintained tyres is very important. Tyres that are well looked after will enjoy a longer lifespan.

However, there will come a point when you need to change your tyres. Time makes fools of us all – and tyres are no exception.

Understanding when you should change your tyres may seem complicated – but there are certain scenarios that indicate that it is the right time to find replacement tyres for your car.

Check Your Tread Depth

The current legal limit for car tread depth in the UK is 1.6mm (across 75% of the tyre). Not only will a tyre become unsafe to use at 1.6mm, but there are also legal and financial implications.

Driving on illegal tyres can lead to a fine of up to £2,500 and the chance of three penalty points on your driving license.

testing tread depth

There are several ways to check the tread depth of your tyres – with some manufacturers even designing tread depth indicators into the tyre. 

However, one quick and easy way to ensure tyres are not at the legal depth is to simply use a 20p. 

Take a 20p and place it in-between the main grooves of the tyre. If the outer band of the coin is visible, the tyre may have insufficient tread depth.

Damaged Tyres

Tyre damage can happen when they suffer impact with solid objects, sharp items, or road defects – such as potholes.

You should aim to give your tyres a visual inspection on a regular basis to check for any potential tyre damage. 

Flat tyres

It is especially prudent to perform a check of your tyres if you have recently fallen prey to one of the many large potholes that pepper the UK roads or have had an unfortunate collision with a kerb.

Keep an eye out for any visual perforations, deformations, or bulges. If you are unsure, it is always best to check with an expert and do not drive on tyres that you suspect are badly damaged. 

Uneven Tyre Wear

When a tyre does not wear in a uniformed way across the tread, this can lead to performance issues and safety concerns. 

The most common signs that a tyre is wearing abnormally is for patches of lower tread to appear in either the central area of the tyre or around the tyre’s edges. 

Grip, braking and cornering performances will all be detrimentally affected by this – and in extreme circumstances, you could even suffer a blowout of the tyre.

The cause of abnormal wear can vary from a mechanical issue, such as incorrect wheel alignment, to running tyres on the incorrect tyre pressure. 

Too much air in the tyre causes the centre of the tyre to be the main section in contact with the road and not enough air in the tyre causes the edges to dominate road contact.

When Should You Replace Tyres

If you have noticed any of the topics discussed above, then it is likely you will need to start looking into replacing your tyres. This can seem a daunting task if you have not done it before. 

However, it is a relatively easy experience on sites such as Blackcircles.com – we work hard to make the whole process as straightforward as possible. 

One of the key pieces of information that you require when replacing your tyres, is the tyre size that your vehicle requires.

If you find that you are asking yourself ‘what size are my tyres?’, there is a simple way to check – by either reading your vehicle’s handbook or by looking at the tyres currently fitted to your vehicle. 

How long does it take to change a tyre?

Once you have purchased your replacement tyres and have booked an appointment to have your new tyres fitted, you may be wondering how long it can take for the whole process to take place.

The short answer is… it depends. Not very helpful though, is it?

The reason ‘it depends’, is that there are a number of factors that can contribute to the length of time it takes to fit a tyre. This can range from the tyre itself to the vehicle receiving the tyres and even the person fitting the tyres.

To try and ensure that there is some quantifiable way of setting expectations though, it is generally accepted that it will take approximately 30 minutes for the fitting of each tyre. 

But it is worth stressing again this an average figure - some tyres may take longer and others shorter to fit.
