Question:

Whats the best density of tires for a racing?

If you‘re in a auto race what tires would be more efficient/desirable?Hard TiresMedium TiresSoft TiresThanks so much!

Answer:

The 'softness' or 'hardness' of rubber compounds is varied for each race according to the known characteristics of the track. Two different compounds are available to each team at every Grand Prix weekend, and every driver must make use of both specifications during the race. The actual softness of the tyre rubber is varied by changes in the proportions of ingredients added to the rubber, of which the three main ones are carbon, sulphur and oil. Generally speaking, the more oil in a tyre, the softer it will be.
soft tires have more grip but dont last long, medium tires last longer but have less grip, and hard tires last forever but have no grip. it just depends what type of race you are in. if its a dash on an oval than you would want soft tires, but if its an endurance race, than you might opt for medium or possibly hard.
