In order to know about tyre sizes, it is necessary to understand the term aspect ratio. Aspect ratio is defined as the relationship of the tyre width to the tyre height. It is also called profile or, more commonly, series.
Thus a 75-series tyre is 75% as tall as its section width. The aspect ratio is derived as follows:
Section height is the dimension from the nominal diameter (bead) to the centre of the tread surface. Section width is the dimension measured from the side wall at the widest point. Currently most of the new cars in India are equipped with 60, 65,70,75,80 series tyres.
Both tyre construction and aspect ratio can have a pronounced influence on the handling and performance characteristics of a vehicle. In selecting new tyres it is advisable to check the car manufacturer’s specifications or consult a tyre professional for further advice.
Tyre manufacturers offer a great variety of tyres for use on vehicles. The use of tyres and / or wheels that have not been approved for your vehicle by tyrestore can be detrimental to vehicle safety.
Your vehicle may be equipped with specially designed, low aspect ratio, ultra high performance tyres that enhance the handling, steering accuracy, braking, and all round performance of the vehicle under a variety of driving conditions.
If your vehicle is equipped with Ultra high performance low aspect tyre n tyres, please make sure that the below mentioned points are read carefully
Ultra high performance low aspect tyres are tyres with an aspect ratio of 60 or less and are speed rated higher than 210 km/ hr (H – Rated). The aspect ratio is calculated by relating the nominal section height of the tyre projecting beyond the rim to the nominal section width of the tyre and is expressed as a percentage. For example, a tyre with a height of 54mm and a tread width of 120 mm is rated at 45.
We at tyrestore hope that the above information that has been provided about Ultra high performance low aspect tyres will help you to enjoy driving your vehicle.
