So... If I go to a 16" wheel, I can get 31" and have a more narrow footprint? I'm also assuming this might make it easier to steer? What about highway driveability? Thanks for the help. Currently looking at 255 70R-15 (29.1" dia. & 10.3" wide) for the rear and 235 75R-15(28.9" dia & 9.3" wide) for the front. I can still change to 16 wheels - its not too late...yet.
