For me tread wise a street tread is fine. More rubber means more wear? I dunno if heat build up affects wear either. Real hot weather increases my pressure. For that reason I run 65 front and 75 rear so the tire warning light doesn't present itself. Nitrogen is supposed to keep a more consistent tire temp. Good for this application?
What is the GVWR of the truck ? If you are close to the limit, you may need a bigger tire to get longer life. Nitrogen does help minimize temperature-related pressure swings.
Checkout Bridgestone Duravis
Bridgestone Duravis R25
^ That one is a pure Summer tire. After people got tired of putting sets of tires on their class B RVs, that is the one my buddy would sell them. Clearly not a low temperature tire, but that's how you get the tread life. If you run high Summer miles, that may be of interest.....
I run their M700 on my one-ton year round. Not Michelin smooth, but a tough LT truck tire that has served me well.
