im going to shoot for to wide on that, last gmt900 truck i did with 9 wide on wheels and bigger than 11" wide tires, had to be trimed, and that was a 4.8 4wd truck. I try to stay with no more than 11" wide of a tire, then you got to watch your style of tire as well....no M/Ts or crazy lug patterns there not measured with the size of the tire. Or if you do they have to be realy skinny like 10" wide.
just good to keep in mind.
cool truck dude...just thinking you know what would look cool...GM makes the Escalade door handles wich are painted black and have a chrome handle peice. That might look real cool on that truck but dont know if just the one piece of chrome will look silly, cuz you got the all black thing going. But in that case if you ordered Tahoe lt3 or denali All painted handles they will come pre painted black....
Just a thought i was looking at your truck and thought about it. I used to do GM parts so i used to sell those all the time.
