Hi guys sorry if this has bin asked before but I could not find any threads on this . I have a 2003 super crew and recently switched from stock p's to some toys at2 lt e tires. they are stock size 265/70r17s I am trying to figure out the best psi to run them at currently 35 front and 30 rear . I don't haul much and never tow its mainly used to get to school or work. thanks in advance

 

Some will tell you to fill the tires per the door pillar decal. I personally go by the tires recommendations and use tire dressing to fine tune the PSI. I spray the tire dressing on and drive around hit some aggressive corners and see where the dressing is still on. the dressing should be off to the corner/ edge of outer tread blocks. My tires recommend 45 PSI but I have found that 42 PSI front and 38-40 PSI rear works perfect. Like I said, everyone has their own methods or recommendations.

 

If they are load range E I think I'd run them somewhere around 40 to 45.
