What’s in a Tyre?

Everything you needed to know about your tyres (in case you were wondering) in a bite sized article.


The tyres on your car can be described loosely as the black round things, shoes, doughnuts and many more but they are best described as the most important feature of your car that you have the most control over.


You decide your own driving style and this is a major contributing factor to tyre wear and economy. Driving too fast or braking hard styles will wear the tyre faster, meaning you have to change your tyres earlier.


Driving with care at a normal pace and slowing your car with reasonable braking can and will, prolong the life of your tyres by a much bigger margin meaning you have money in your pocket with fewer tyre changes.

The details:

Each tyre has a wealth of information imprinted on them for both the purchaser and manufacturer, a mini manual if you like.

The first question which is always asked is what tyre size you want. The tyre size is embossed onto the sidewall of the tyre:


205 is the tyre width in mm 60 is the ratio of the sidewall to the width (60% of 205mm) the R means its of radial design (reinforced with cord) and 16 is the rim diameter.

Tyres also have a ‘use by’ date. You should never drive on tyres that are older than 5 years as the rubber begins to degrade and the components within the tyre may no longer be able to hold the stresses of speed and weight. The manufacturer date is 0318 (March 2018 - Use by or before end of 2023) 


There is also a ‘speed rating’. This determines the maximum speed that a tyre can be driven at.  Speed ratings for the average car typically start from as low as Q (with a maximum speed of 99mph/159kmph) and as high as Y (max speed 186mph/300kmph) also appear on the sidewall. Do not drive at these speeds - they only indicate the highest speed a tyre should operate without malfunctioning. (96V - 149mph/240kmph)

And finally there are seasonal tyres from summer to winter to cross climate to all weather. Each tyre will handle specifically to the conditions they perform under. You can normally tell by the tyre tread what type of tyre it is. The main difference is the compounds in the rubber and how they react to the weather conditions.


L/R, Winter, CrossClimate, All Weather and Summer.
