I have a 2006 SE CrewCab Frontier 4X2, stock 16" rims, 265/70/16s Bridgstone.
I recently put a "mini" leveling kit on it, 2 inches in front, 1.5 in back and its time to change my tires.
I drive to work, pull a light camper trailer 5-10 times a year for short 200 mile round trips.
No offroading, but I like the all terrain look and beefy stance of the truck.

I want to beef up the tire just a bit to give the truck a bit more lift and a bit beefier look (no new rims yet) with the leveling kit on it now..
Would a 265/75/16 be the tire to go with? Or is there a tire that is a little wider that would be a good fit too? I dont want to go huge/mud/traction tire, i would like to keep getting 17-21 mpg like I get with my current setup.

Let me know what you think.
thanks for the info
Brett
