I know that many (all?) Mercedes Sprinter wheels will fit on the Grenadier since they have the same bolt pattern (excluding the dually models of course). Is it safe to assume the reverse is also true (IG wheels will fit on a MB Sprinter van)? Are the offsets compatible? What about the tire size? Just wondered if anyone here has done that yet or happens to know since it seems so many IG owners also have a foot in the Sprinter world (or used to).
