Nitto Terra grappler 285 75r16's. they are an awesome tire, i would highly recommend them. I did some calling around and haggling and got them for 650 OTD at discount tire.
they fill out the truck nicely, ride great when they break in, they feel a little squishy until a few thousand miles. my fronts are in prefect shape after 2 winters ~15k miles and my rears are almost toasted for obvious reasons. I'll be replacing them with the same thing.
