Are you looking for Tyres Size for your vehicle?


Mounting tyres of the right size is crucial to your vehicle’s safety and performance. You may notice that different car makes and models require varying tyre sizes. You try experimenting with this factor, and that can affect a tyre’s longevity and wear, as well as the car’s safety.

That’s why we at PSM Tyres and Repair Centre always recommend our customers to refer to the car manufacturer’s manual when they buy car tyres Brighouse. You might also know that you can find this piece of information at the sidewall of your vehicle’s tyre.

However, most of our patrons do not understand clearly what such alphanumeric code at the sidewall of their vehicle tyre signifies. If you are also uncertain about its meaning, read along!

Understanding tyre sizes

The format for tyre size is similar in all modern tyres. For example, if you own a performance car, the tyre size might read like 235/40 R18 95 V. Each of these numbers and letters – 235, 40, R, 18, 95, V – signify a particular tyre feature, which complements such vehicle’s overall performance.

Let’s decipher these numbers and letters to understand better, so you can buy new car tyres Brighouse more soundly:

  • Width

The first three digits denote the width of the tyre in millimetres. Thus, as per the above- mentioned example, the tyre’s width is 235 mm. Different cars require tyres of varying width. A vehicle might need tyres with 175 mm diameter and another may require a width of 225 mm of width.

  • Aspect ratio

The next two digits – 40, as per the example mentioned above – represent the height of a tyre from the tread’s base to rim. It’s shown as a percentage of the tread width. Therefore, if we consider that example, the tyre’s height is 40% of 235 mm.

  • Construction type

This letter denotes the construction type of your car tyres Brighouse. You may notice that most tyres today carry the alphabet R. It signifies radial tyres, meaning it has radial ply construction. Other construction types include D, which stands for diagonal, and B for belted.

  • Rim diameter

The following two digits in the tyre size format represent the wheel rim’s diameter. In case you are planning to buy wheels for existing tyres Brighouse, you will need to buy them as per this measurement.

  • Load index

The next two-digit number shows the load index. It can also be a three-digit number. Also known as load rating, it is an industry-standard figure denoting the maximum weight that a single tyre can carry when properly inflated.  For instance, if your car tyre shows a load index of 88, its maximum load capacity is 600 kg.

  • Speed rating

The alphabet at the end stands for speed rating. It signifies the maximum speed at which the tyre can be operable safely, given it is correctly inflated and fitted. The highest speed rating is Y, which denotes a maximum speed of 186 mph.
