Wide tires get floaty, Floaty tires are good for mud, but bad for rain, snow etc. They would probably look great, but you might be going past a good working wheeler, into more of a show jeep.
It gets my goat when im at a show and everyone is soooo impressed with a jeep with 44 inch tires. I want to tell them, that its not a GOOD jeep with tires that big. It only looks good to people who dont know what they are looking at.
rant over.
