The Mastercraft only comes in a 315/70-17 and it runs a 34.49 overall diameter. That is pretty typical. Should look the way you expect it to when mounted. Go for it. You will have plenty of lift at 3" to clear the stock fenders.
Some folks are fine with being screwed over, perhaps finding confrontation to be more stressful than just living with whatever the problem is. These are excellent consumers, manufactured to the finest specifications.
Reformed Jeep addict... Jeepless for now.
