hey i just got my FK452 installed on my 18 inch i have my psi at minimum requirement located on the side of the driver side door 32 psi front and 35 psi rear... sunday i had a little road trip to the beach and i had a full load of people in my car and i told my passengers to shut the hell up cause i was going to fill my tire at the gas station to the maximum psi load LOL believe it or not rides lots smoother better mpg. I asked someone regarding a higher psi and his reply was higher psi the better MPG but faster wear of treads and minimum PSI better grip on the road and does not wear as fast. I added 2 psi on top of the minimum requirement so now i have 34 psi front 37 psi rear and im finally pushing 21 mpg on highway.
