My sidewall on the tire says 125psi, is that the mat of air I should run or is that th max amt ?
that is the max. you generally do not want to use the max unless you are quite heavy, because it will give you a very choppy ride. it doesn't grip or handle any better than lower pressure too, within limits. there's an ideal range.
if you post your weight and the size of the tire (23 or 25mm, most likely) then people can give you range of how much air you need to use.
