I did a search on this and nothing came up.What psi are you running on??? The gas tank covers says to run your tires on 33 psi fronts and 42 psi rears on a max load. The dealership told me to run on a higher psi of about 38-40 front and rear. Any suggestions on what is the proper psi to run on is for these tires on the 337???? Thanks for any feedback!
