My Honda manual says to run 4.5 psi front and rear. That seemed kinda low so I took it down to about 6 psi and was afraid to take it any lower. At 6 psi they looked like they could fall off the rim. Is 4.5 psi correct for general off road riding and if so should I adjust as soon as possible? Right now I'm running 10 psi front and back? Is that too much? Thanks.
