looking for new meats for the truck. its an 05 GMC quad cab 4x4. stock size is 265x70r17. (they are P rated tires too. terrible) want to put a bit bigger size on but not sure they'll fit. not interested in playing with suspension aymore. would like to throw a 285x70r17 on there but don't know if they'll fit. if they rubbed the front bumper thats fine, i can cut the airdam to clear em. just worried about the inner fenders and upper fenders. thanks!
