According to a natural law, the friction factor of an object on a surface is independent of its surface. That is, if you move a 1kg metal cube on a wood surface, for example, you need as much force as if you are moving a 1kg heavy disc from the same metal with correspondingly larger support and on the same wood surface. That means that both metal objects have the same “grip” So why do you need wide tires or better why do wide tires have a better cornering position than normal tires? Many motorsport reports from Formula One prove that this is the case at the moment. The good shoemaker complains that the tyres are less wide than last season, which supports understeering. However, according to this natural law, this should not be the case at all. So why is this the case?
