Tire companies, now you don't need to spend millions on setting up labs to test durability of tires on Indian roads, one of the farcest (!) growing car markets in the world; simply fix the brand of your tire on to some vehicle and get it driven on roads of Bombay during the monsoon season! This way, you will be able to test shocks and struts (!) on tires, as well as measure great (!) road depths at which your brand of tires are able to with hold pressure and tension of the car as well as the car-driver and all that swear and tear!
