Why would you need more pressure in back when the motor is on the front tires? Well unless your towing all the time anyway......LOL

 

i learned this trick from my shop teacher a few years ago... if you wanna make sure your tires have the proper inflation you take a piece of chalk and mark a line across the tire tread... drive it up and down the road a little bit and see how the line has worn. if the middle of the chalk is gone you have too much pressure, if the outside is gone but the inside isn't then you dont have enough... you know your golden when the chalk has worn off evenly...

 

i have 265/70-16`s. What pressure would be ok? I put 32 today, they were on 28. What would be best in your opinion? No towing at all.

 

depends on brand and how much weight you typically carry in the truck, as well as driving conditions and driving habits, the best way to determine optimal air pressure is with the chalk line test, put a set pressure in your tires and draw a chalk line across the tire tread and drive down the road, if the center fades faster you have too much air, if the outsides fade faster you have too little air, it should wear off the tread evenly
