You may do well with your choice. But think first...
I went from 275 stockers to 315 Nitto's. My real mileage didn't change much. 315 is a 35" tire and fills the fenderwell nicely with a 3" lift without rubbing on stock bumpstops. I see stock trucks with the same tire often.
My gas mileage, according to the odometer went down. But when I correct the real miles traveled for the larger tires, I get the same mileage in standard mode. In Power mode, which I use most of the time to help make up for the larger tires, I have a loss of mileage. It is small enough that I don't notice unless I am counting every tenth of a mile at every fill-up.
I.E. The difference in speedo and odo readings with the 315's is about 14%. The change in fuel mileage according to the odo is close to the same. So the real change in fuel mileage was close to zero!
