The Dealership and your manual will tell you 4psi max. I try to run around 3psi, but if the weather changes as much as it does here in Oklahoma, you will want to check it each time before you ride.

Big_Daddy, Having more air in your tires will actually let you have less grip... Less air more the tire will act as a tread, and crawl/climb over things. That is why people get bead locks, so they can run really low PSI and not push the tire off the rim.
