Finding out Your Tyre’s Age

Knowing the age of car tyres is very important. Just locate an embossed window on the sidewall of your tyres. There you will notice four numbers.

Making Sense of the Tyre Markings

You need to know how to read the markings properly so that you replace your vehicle’s tyres with the right ones. It will also help you to maintain safety and benefit from a great performance.

Let’s suppose your tyre markings are as follows: 225/45 R 18 95 H

Let us decode this marking:

• 225 is the nominal tyre width. The unit of its measurement is millimetres.
• 45 is the aspect ratio of your tyre. Aspect ratio means the height of your tyre outward from the point of the rim. It is shown as a percentage of the width of the tyre. The aspect ratio is calculated by dividing the section height of the tyre by the width. An aspect ratio of 45 means that the height of the tyre is 45% of its width.
• The letter R denotes the kind of tyre construction. Here, R stands for radial construction. If instead of R you read B, then it means biased-ply construction. If the letter is D, t stands for diagonal construction. Most tyres have radial constructions. It means that the inner ply cords of the tyre are set in a radial direction. You will find R written on most of the tyres today.
• 18 denotes the diameter of the rim. It is measured in inches.
• 95 means the load index of your tyre. Load index means the highest weight or loads your tyre can carry while it is properly inflated. Load indices of tyres on passenger cars range from 75 to 105.

H is the speed rating. The speed rating is represented from letters beginning from A to Z. H here means that your tyre has a maximum speed of 131 miles per hour or 210 kilometres per hour. As you progress in the alphabet, the maximum speed of the tyre increases.
