Preference on what works for you really.
For us thicc riders (230lbs), running 45psi seems impossible (factory ares tires) if you are trying to do any sort of spinning trick well. If I roll in a straight line I'm okay, if I'm doing any sort of scuff or squeak I'm fine, but when I start spinning I can hear the tires being mushy and its very slow / sluggish.
I'm putting about 65psi in my current tires now, and I'm waiting to inevitably blow out the side of these things. I have a set of Frequency G's coming so I can run 100'ish psi with less fear of blowing out and I expecting that it will provide a more firm tire that isn't screaming under my weight.
