Yet another tire question. I have a 2017 Trailhawk with the Avid 2 inch lift and 1.5 inch wheel spacers on the way. If I use the stock 17 inch Trailhawk wheel, what's the biggest set of BFG KO2's I can use? This would be a much easier option than dealing with all the different measurements with trying to go to a 16 inch wheel. Thanks again.
