I think i read somewhere, that the maximum working temperature is around 110°C and working temperature 100°C, but dont quote me on that. What definitely changed is that the hot pressures should be between 27,3 and 27,9 psi, but not that big of a change either.I bought the 2020 GT WORLD CHALLENGE PACK and it says it has the new 2020 Pirelli "DHE" Tyre Model. Does anyone know what the optimum Temp range these Tyres run at
