I usually start at pressures of 30-28 psi and end up with 38-42
I recall you posting earlier about tire movement on the rim. While I am not aware of this happening to me, I am mounting new BFG GForce R1s 275X35X18 this week (to replace the ones I am selling) on Apex 18X10 rims and I plan to mark them so I can monitor any moving. After a bunch of testing, I settled on 34/33 cold, looking for 42/39 hot which has seemed to work out okay. My temps run higher on the front than the rear.
Thanks for the info. I'll advise if anything occurs.
