33" is the stock tire height. However on the 06-08 4x4's if you want to run 33/12.50 or 305/55's on the stock wheels you will need 1/4" spacers.I was hoping someone had some pics of a 06 or newer 1500 4x4 with stock chrome wheels and larger a/t tires. like 285/70 or 33/12.50. Is this the largest tire that can be stuffed under them at stock height.
sorry, I thought you had the 20's :thatfunnywhat about 285/70-17. don't want to run spacers.
