I've got new tread on the front and rear tires. The installer maxed out the psi when he inflated the tires. Front is max 36 psi - rear is max 41 psi. (Bike mfg settings - not tire mfg settings) I didn't like the way the bike handled when cornering so I set the pressure at 34 psi front - 39 psi rear and the tires seem to be gripping better - slightly more tread on the road I suppose. Where do others set tire psi?
