To tell you the truth, I really don't know. The truck is being shipped to me on Monday, so I probably won't get it until Wednesday. It's the Motorsport Ed. w/the stock Eagle #1's. but I'm wanting to go a little more low profile than those. I'll see what I can conjure up. I'm looking for a general view. If a 3/4 will work on the stock tires that's great; I'm not going to change out perfectly good tires...if not, I'll do the 2/3 and change it later if i need to.
