What are tyre compounds?
Tyre hardness/softness is measured in degrees, these represent the compound. Harder compounds last longer but have less grip. Softer compounds do not last as long but have more grip. Most tyre companies give their tyres degree numbers, like 8, 10, 15, 20, etc; the lower the number, the softer the compound. However, not every company uses the same numbers. For example, a Kyosho 20 would be the same as a PN RCP 6.
