Proper psi for FAT Bike racing?

[mtrsprt43]

I think roadies run like 120 psi so they are faster and have less rolling resistance . I would go a step further and fill them with helium like a blimp to at least 150psi. That way you will be fast and light ....

Assuming you're running stock meat (Larry / Endo) For normal Beverly Park conditions, I find 10 psi to be just about right. Grip it and rip it superman.
