Re: tire size help..

Stock tires are just about 32" so I see no reason why a 33.5 wont fit. Here are mine they are 31.7" so a 33.5 is basically 2" taller. That would then mean another 1" is required all round. There is at lease another 1" clearance all round in the old pics here. So as for wheel well fit it should be fine, but I don't think you can mount the rears as dually's unless using a spacer.
