I need your expertise. I just recently bought a used 2004 F150 XLT Extended Cab, 5.4L, 2WD. My question is, being an older truck I didn't wanna spend too much money on this vehicle which will be on the highway more than off the road (it's her truck). Just for looks, I wanted to add the level kit, and the advertisement said it can fit the 33 x 12.50 under the fenders. Is this true anyone did this before? Don't wanna spend the money shipping the items and the tires start rubbing the under carriage. If someone out there can tell me what the off set on the rims would have to be, to accomplish this

Thanks
