I have a 1997 2WD Silverado extended cab with no real modifications. The only change from factory is the tires. 31x10.5x15 Goodyear Wranglers. I am beginning to have significant wear on the outside edge of both front tires. the tires are approximately 9 months old. Would the increase in tire size without any suspension modifications effect the camber of the front wheel? Any help would be appreciated.
