But why are our tyres on regular cars different from the Formula-1 cars.

The basic difference is in its tread. The formula one car tyres are huge and have plain treads. The full tyre gets in contact with the road completely. This helps the car gain speed and is not hampered by force of air at all. Moreover, these tyres are filled with nitrogen-rich air mixture which minimise fluctuation in parameter like pressure and temperature. That’s why they are able to achieve magical speeds.

But consider our car tyres, they come with different treads and have gaps. The logic is that the road grip of tyres. The tyre grip on the road causes friction as it moves with force on smooth surfaces. The main reasons for wear out are friction. The effect of friction is different on various surfaces like metalled roads, stones and asphalt. Thus worn out tyres have greater contact with road. Tyres are also exposed to sun and rain. Due to continue exposure to harsh climatic conditions the tyres get hardened, there by reducing friction. Even continuous exposure to rains, give the same results. However, the tyre undergoes a process of expansion and condensation before the tread is affected.

Now let us talk of the gaps in regular use cars. The gap balances the weight of car and also channels out air, dust stone from the tyre. In comparison, the F-1 cars race on dust/gravel/stone and water free flat roads. But regular tyres are used on all roads. They are used in all climatic conditions. The reasons for wear out are numerous.
