Hi, I've installed BF KO2 225/65/17 on My 2016 CX-5 and currently the psi in them is 45. I'm feeling very stiff ride; feeling every little bumps or pot holes. May I know the best psi setting for better and safe ride? Or is it at the correct psi? Also, on the tire it's written 65 Max psi..but on the sticker in new tires it's written "Never inflate more than 40 which would effect the beads or something...". Original settings for OEM geolander 91 is 32 psi. Please HELP!!!!!
