You haven’t provided a tire size for your truck so I’m going to provide a little hypothetical info for you. It’s all about load capacity.
Lets say your OE tires are P235/75R17SL and their sidewall states they will provide 2205#. This is important. When installed on a pick-up truck "P" rated tires MUST be derated. That is done by dividing the 2205# by 1.1. So, their real load capacity for your application is 2004#. To see what your installed tires are providing at the vehicle manufacturer’s recommendations you will have to use a load inflation chart and then divide the actual load capacity at those inflation pressure by 1.1 to get the true value for your application.
Lets say you choose the LT245/75R17E tire as your replacement. That tire provides 3195# of load capacity at 80 psi. (Will your current rims work)? For that kind of plus sizing all you have to do is provide the load capacity the OE tires provided for normal every-day operation. The psi needed to do that is going to be much less than 80 psi and the ride will be much better at the correct inflation pressures.
By the way, both of those tire sizes and specs are for Michelin tires.
