These are 37x13 on an 8" wheel
Not bad, but your tire is 4" taller than a 33, so it looks less "balloon" like.
The wheel/tire combo first caught my eye is the second post of the "jap bed round fender" thread (the black 1st gen)
http://board.marlincrawler.com/index.php?topic=13593.msg147591#msg147591 . Those look like 8" wheels, and the sidewalls look to "balloon" like to me. IMHO, that would look better with a 10" wheel. I guess I just have picky taste.
One day I'll learn "function over form"
