I have a NNBS silverado and im in the market for new tires however i want to know what is the largest tire anyone has used with a 2" leveling kit? I want a nice agressive off-road tire and i want to use the largest possable. Also these will be going on OEM Z71 18" wheels so my tire choices really suck for an 18". I want to know if a 33X12.50R18 will work if they make that size. Also anyone who has a similar setup please post some pics so i can get an idea of what it will look like.
