Cooper stt pro

Hey guys was looking at getting the cooper stt pro in 315/70/17, believe that's the equivalent of the 35. I was curious how true to size these run? I've heard the bfg ko2 runs very small.

Anyone have any idea?

Mine in that size ran 34" under the jeep at about 33-34 psi. I've decreased to about 29 psi since then but haven't measured again.

From what I've read this is about average for 35s
