he is also on swift springs, which are notoriously lower than advertised. I think with prodrives you would definitely be alright with 235, most likely 245's with proper alignment. With something like the usdm wagon pink springs, you would definitely be alright with the 245's. Plenty of poeple out there are running similar setups on their wagons. Its all about not too much drop, rolling the rear fenders, and proper alignment. Oh, and not picking a tire that is really wide for its size helps too.
