A little help from some S4R owners. The owners manual states 2.1 bars front and 2.2 bars rear which on the web converts to 30 psi front and 31 psi rear. Is this correct or better yet what kind of pressures do you run. This seems a little low to me. I checked my pressures and they are front=35 and 41 rear. Does this sound right. Thanks for any help.
