The requirements to racing car tyres are stricter, than to usual tyres: high reliability and durability against rupture under the influence of very high loads, sufficient resistance to wear, providing a good vehicle stability and the lowest rolling resistance.
To the highest loads are exposed racing car tyres, designed to establish the absolute world speed records. For example, if the rolling radius of 550 mm and a speed of 140 m / sec (504 km / h) only under the influence of centrifugal force per gram weight of the tread on the circumference of the wheel is loaded by the force of 4 kg, i.e., 4000 times its own weight. At a speed of 500 km / h deformation of the irregularities of the road 125 times larger than the deformation at a speed of 100 km / hour.
Even for road-racing cars at speeds of 200-220 km / h and tyre rolling radius 330 – 350 mm tread when moving loaded by the centrifugal force of about 1000 times its weight.
Therefore, racing car tyres offered by ozzytyres are made of quality materials. For cord is used natural or artificial silk, and recently tissue-type “Capron”. Frame is made of steel wire with a very high tensile strength. To tread the best grades are used natural rubber. Click here to read more.. »
