Tyre Specifications for beginners

Tyre specifications are written on the sidewall which needs to be deciphered to know exactly what it means. The information given on the sidewall of the tyre is as follows:

1. Width- Cross Section width of the tyre (always in mm).
2. Profile- Aspect Ration (%age of the Cross section width).
3. Diameter- Rim Diameter (always in inches).
4. Load- Load Index.
5. Speed- Speed Rating.

The load Index corresponds to the load capacity given in the diagram below. That shows the load bearing capacity of the tyre. The diagram given below depicts the LI of the tyres.                        

The speed category is designated by the alphabets as given in the diagram below.                         

If there is any clarification needed then you can please ask questions in the comment box. We shall discuss all aspects related to tyres.

Tyre Usage

This is the introductory blog of Tyre Gyan in which we would be discussing the usage of tyres. Tyres are the most important part of the vehicle and has a high replacement cost. We should always take care of our tyres as they are expensive and also have an important part to play in our safety while the vehicle is moving.

The usage of tyres are as follows:

1. Controlling the movement of the vehicle.

2. Carrying the load.

3. Absorption of shocks on the road while moving.

4. The tyres help in handling, turning, cornering, braking etc.

5. Critical contact point between the road and the vehicle.

It is always important to wear good tyres with sufficient Tread depth so that in case of emergency braking and rainy seasons we are able to avoid accidents and other unfortunate incidents.
