I did another auto x with Windycity Miata club last weekend.
I was shocked how many runs they do. 17 runs!
Anyhow, tire felt great with ton grip, but they do overheat very easily. (well with 17 runs..lol)
When it overheats, it does get greasy and I did not have any water to spray.
Still, my time was very consistent for last 10 runs in dry. First 7 runs were in rain.
In terms of pressure, I was running 32 in front and 30 rear. Tire temperature was about 165F. I felt tire lose grip a little when temperature was over 150F.
Next time, I will try to spray water as it heats up.
