I have a reversed 140/90 on the front right now, original Commander. I only run it reversed because that's what I always read that ya do, but I don't think it makes much difference with the ply construction of these tires. 140/90 is the tallest 16 incher that is designed to work with our wheels, and I like ground clearance. When I go Commander II, I think I will go with the 140/90 rear and the 130/90 front. Another thing I like about the 140 is they are virtually all load range B 77H tires, and they are lighter weight than the 150/80. I don't know if the 140/90 on the front gives much to my handling now, but When my suspension is done, there won't be a doubt.
