Application: The first in the sequence is the letter P which stands for the passenger. It is the application of the tyre which means this tyre is best for a passenger vehicle.
Width of tyre: Next is the width of the tyre which is measurable in millimetres. The measure of this tyre from the beginning of the surface of the rim to the end of the sidewall tread is 185.
Aspect ratio: Here the aspect ratio of the tyre is 70. The aspect ratio presents the height of the tyre in respect of the percentage cent width. This means the height of the tyre is 70% of the width of the tyre.
Construction: The construction of the tyre differs and is in form of alphabets. Common construction of the tyres is R for radial construction, B for bias ply and D for diagonal construction. Here the tyre also has radial construction.
Diameter of the rim: The diameter of the rim is also the height of the tyre which you can measure in inches. Here the diameter of the rim is 14 inches.
Load Index: As you must be aware that tyres are the only contact between the road surface and the vehicle. This is why the burden of carrying the vehicle, and the passengers inside, falls on the tyres. It is the maximum weight that tyre tyres can safely carry. If you put any more weight than this, you might end up with a tyre blow-up or tyre failure. Here the load index of the tyre is 98 which means it can carry up to 890kg of weight.
Speed rating: You might have noticed that racers don’t use the regular tyres that you use for racing purposes. A speed rating is a maximum speed at which it is safe to drive your vehicle. Different alphabets define different speed ratings, such as H means speed rating of 210km/h or Y means speed rating of 300km/h and so on. Here T means the tyre has a speed rating of 118m/h or 190km/h. However, it is not specific as it is not really possible for one to find out the exact speed rating of a tyre. Many surveys and observations have concluded these speed ratings are safe to drive with. Keeping that in mind we also suggest you not go above the given speed limit as it is illegal. It can also be dangerous to drive at such speed and you can easily lose control over your steering.
Apart from the size, there are some other markings on the sidewalls of the tyre that tell you more about your tyre’s uses and authenticity. These markings are:
