Living with 3.91's

ok, ok
i recently had 4.30's and didn't like getting on interstate for anything more that an exit or two. (26.5 tire). i switched to 3.23 and it's a little sluggish,
but tolerable. a 3.91 can be "stiffened up" with a short tire and you can get a little break for the highway using a tall tire (28 or so), making it a good decision
