I installed BF A/T KO 315/70R17 last month , the guy at the shop put 50 psi on all four tire (as per the max load on the tire) , but now my tire look like too much inflated, especially on the rear
What is the best pressure

Take a piece of chalk and draw a line straight across the tread, shoulder to shoulder. Go for a drive. If only the middle of the line is gone, let out some air pressure until the whole line disappears.
thats what i ran in my bfg a/t 315's on my old chevy, thats what i run in my bfg a/t's on my jeep wrangler, but i do only run 45 in the bfg a/t's on my DRW, even with that, my drw's don't wear all the way acorss. the ride is bumpier witht hem inflated to 50, but i'm tryin for the best mpg in all my veh. my .o2
40-42 front, and 35-37 rear usually works well for me, but I run a 10ply "E" rated tire. Wheel width will also play a role in how much air you can run without causing premature wear on the highway. I also inflate about 5psi more when I tow my trailer.
Thank you BigB82789 for the info, i do the chalk test then i drop my front to 44 and the rear to 40 , my truck ride a lot better also since that :thumbsup
