Just wanted some input from anyone running the 615s in autox. What pressures are being ran. I ordered a set of 245/45/17s, due to STU tire width reg of 245. I have heard how stiff the sidewall is so I curious to know about pressures for the 615s.

I was running anywhere from 39 to 43 lbs front on my NT555s but, those tires can't hold a stick to the 615s so I am assuming the pressures shoudl be dropped a bit.
