The van cam in about a week ago. As mentioned in the posts below I got 17" rims on 285 tires, no lift. The pic does not do it justice. (285x75x17) Those rims and tires have great agressive proportions without making the van too big.
However they did not (and still don't) fit perfectly. The dealer did some cutting to the plastic liners and a bit on the metal. Needs more. Not a huge deal. I'll post more as I get to it.
