UK Law & Regulation:

UK law requires that your vehicle is fitted with the correct type and size of tyre for the vehicle type you are driving and for the purpose it is being used. 

With potholes and kerb bumps, tyres can quickly become compromised. Regular tyre checks can prevent points on your licence, fines and keep yourself and other motorists safe. 

We recommend replacing at 3mm. At 1.6mm, in wet weather, it takes an extra car length (8 metres) to stop at 50 mph than if your tread was 3 millimetres. 

At We Fix Any Car, we offer a range of tyres from budget to premium brands such as Pirelli and Bridgestone. We keep stock of the most common tyre sizes. We can arrange for same day delivery on most tyres, if we don’t have it on the shelf! 

How often do I need to replace my tyres?

Ideally, tyres should be replaced when the tread wears close to 1.6mm. However, there are several other factors which could warrant the tyres to be replaced sooner. These factors usually compromise the tyres structural integrity thus rendering the tyre no longer safe to drive on. Some examples of these are: 

  1. A cut in the tyres sidewall which results in the cord becoming visible. 
  2. Bulge In Tyre – This generally occurs as a result of kerbing. The structure of the tyre is weakened, and the bulge is created by the internal air pressure of the tyre.

Can I drive on tyres with less than 1.6mm tread?

It is illegal to drive on tyres with less than 1.6mm tread. Motorists driving with illegal tyres can receive 3 points on their licence and a fine of up to £2,500 per illegal tyre! Illegal tyres can also void your insurance. 

What is my tyre size?

The tyre size on the vehicle can be located on the sidewall of the tyre. The tyre size is stylised in the format 195/65R15 91V.  

How to interpret sidewall markings on tyres:

  1. The sequence of numbers and letters on your vehicle’s tyres make up the tyre size code. This information can be broken down in the following way 


1)   Tyre Width – The first 3 numbers of the tyre size represent the width of the tyre. This is measured in mm from sidewall to sidewall. For example, a tyre size of 195/65R16 would measure 195mm across the width. 

2)  Profile – The profile of the tyre refers to the height of the sidewall which is measured as a % of the tyre’s width. For example, if your tyre size is 195/65R16, the profile of 65 is equal to 65% of the 95mm width. 

3)  Tyre Construction – The letter ‘R’ means that the tyre is of radial construction. This method of construction is used by most tyre manufacturers today. Some fewer common constructions are ‘D’ for diagonal and ‘B’ for Bias Belt.  

4)  Rim Diameter – The rim diameter refers to the size of the alloy or steel rim in inches.  

5)  Load Index – The load rating on a tyre is essentially the maximum weight a tyre can carry when the tyre is inflated to its recommended pressure. Take a look at the table below which shows the weight each index specification can carry: 

6)  Speed Rating Index – A tyres speed rating indicates the top speed a tyre can perform at under optimal conditions.  For example, a tyre with a speed rating of H can perform at speeds up to 130mph. This is only under optimal conditions. This may not be the same where road surfaces are comprised by snow, rain etc…
