tire pressure question

I have a 6.5 pro comp lift with pro comp 35inch xtreme all terrians max pressure is 50 but for a good ride people told me to run like 38 psi. They told me to chock line across the tire and drive with diffrent tire pressures till the line wears off even then you'll get max tire life without wierd wearing. So I was wondering if other has heard of this and also what tire pressure do you run. Thanks

it sounds like you have a C load tire. if the max pressure is 50psi. I wouldnt do any heavy towing. with them tires. but i would run about 40 in them. White out a line across your tires and take it for a spin. Keep doing thistill you get them wearing flat. but dont go over 50psi.

A chaulk line is just making a line accross the tire with regular chaulk (kids sidewalk chaulk) then when you drive it it will wear the chaulk line off either in the center (too high of pressure) or on the outsides (too low pressure) or it will wear evenly if the tire pressure is just right.

I use an infared thermometer, drive the truck at highway speeds then take readings on the outsides and center of the tire, when i get an even temp accross the tire i got it right.
