Question tire pressure

Hi guys,
I just had a set of Nitto 325 70R 17 Terra Grapplers put on my 2006 Ram 1500 TRX4. It is the regular cab, short box and I had a 2 1/2" leveling kit with 1" wheel spacers put on to clear the tires. The wheels are the factory 17" x 8" wide. The tire dealer put 50# of air in them, but Nitto said 40#, most of my driving will be paved highway. Any suggestions?

the best way to find the correct tire pressure for your truck front and rear is the CHALK method / steal your sisters or daughters side walk chalk and make a nice wide straight line across your tires and drive straight for a 100 feet / if the pressure is correct the chalk will be worn off evenly / if its worn in the center you have to much pessure / if its worn on each side you dont have enuf / and dont forget to rotate your tires every 5 to 7 thousand miles or every other oil change
