When building setups with rFactor 2 I often mind myself wondering how to approach tyres apart from feeling when they have grip. Since ISI has released of lot of tyres both in a pack and on their cars I wonder if there is an overview of the temperatures and hot pressures these tyres perform best at. Is that data available? For example when driving the Nissan GT-R GT1 with its S7 tyres I find it hard to find the sweet spot. Any help is appreciated. Thanks in advance.
