How to check tyre tread depth


Tyre Tread Depth

The purpose of tyre treads is to keep your tyre in contact with the road during wet weather, so it’s really important that you stay on top of checking this. Luckily, checking the depth of your treads is really easy to do yourself, with something as simple as a 20p coin!
All you need to do is place a 20p coin into the main tread grooves of your tyres, and if the outer rim of the coin is fully covered by the tread, your tyre’s tread depth is above the legal limit.


How to Read the Codes on Your Tyres


Every tyre has alphanumeric codes on its sidewalls, and it is vital that you understand what these mean to ensure correct tyre usage and to make replacing the tyre easier.

Tyre Width and Aspect Ratio

 The first code you will see is the tyre width and aspect ratio. An example of this would be 205/55. The 205 in this code represents the nominal section width of the tyre in millimetres and defines the distance between the inner and outer sidewall of the tyre – meaning this tyre is 205mm wide. The 55 in the code is a percentage and demonstrates the relationship between a tyre’s height and width. In this case, 55 illustrates that the height between the top of the tread and the rim is 55% of the tyre width.

Construction Type and Wheel Diameter

The next code you will see on the tyre is usually the letter R followed by two digits. The R stands for radial and refers to the construction type of the tyre. Radial tyres have been designed with the cord piles positioned at a 90 degree angle towards the direction travel for additional strength. The majority of new tyres made today are radial tyres. Don’t worry if your letter is different, it simply means you have a different type of tyre. The important thing to remember is that you need to replace the tyre with the same letter coding as the one you have already.
The two following digits represent the diameter of the wheel that the tyres are built to fit and is given in inches. For example, if the number is 16, the tyre will fit on a 16 inch wheel rim.

Maximum Load and Speed of Tyres

The final code in the string of information on the tyres is the maximum load and speed of the tyres. An example of this code could be 91 V. The 91 demonstrates that the maximum load a single tyre can hold is 91kg.
The V is the standard speed rating on most tyres and corresponds to the maximum speed which a tyre can reach to be able to carry its maximum load.
We understand these codes can be confusing at times, so if you’re ensure on any of the codes on your tyres, contact your local TCH Ford and we will be more than happy to assist!

Winter Tyres


 Winter can present challenges for many vehicles, highlighting the importance of ensuring your car is well-prepared for the colder months.
Winter tyres can be extremely advantageous due to their enhanced grip and traction in colder weather. These tyres feature deeper treads, narrower cuts and a softer compound, helping with the dispersion of snow on the road and improving contact with the surface.
While not obligatory in the UK, it is advisable to switch from summer tyres to winter tyres as temperatures drop, particularly if you reside in a rural area where you’re likely to run into snowy weather.
The cost of winter tyres varies depending on the vehicle and wheel size. Although they are slightly more expensive than summer tyres, the long-term benefits include extended durability of your summer tyres through seasonal swaps, resulting in overall savings.
