Tyres size explained
You can find the tyre size code on the sidewall of the tyres. To make sure, your vehicle has the right size tyres mounted (especially if you have bought a used car), have a look at the so-called Tyre placard – a metal label you can normally find in the driver side door frame, inside the fuel cap or in the glove box. You can also find the tyre size information in the vehicle handbook. These alphanumeric codes provide vital data about your car tyres.
First three digits denote the sectional width of the tyres.
Next two digits signify the aspect ratio or the profile of a tyre. It is obtained by dividing the height of a tyre’s sidewalls by its width and then multiplying it by 100.
Almost all new tyres sold in the UK are of radial construction. Hence, they are denoted by ‘R’. Other types of tyre constructions include diagonal-cross ply and bias belt. They are denoted by ‘D’ and ‘B’, respectively.
The next two digits in the sequence show the size of rim diameter in inches.
Load index: The next two numbers represent how much load a car tyre can withhold when inflated to its optimal, safe limit.
The speed rating shows the maximum speed up to which a tyre can run safely with its corresponding load capacity. It is denoted by different letters like ‘H’ ,‘V’, ‘R’, ‘S’, etc.
