finally something I can answer...tread width is total outside-to-outside
rubber on the ground. B So if your tire tread is 5", add that to track width
and you've got, uh, 63 inches for tread width. B (Shwew, I can still add...)

Hit delete now.... and no, you do not have to answer or reply... No, I am
not seeking rule changes...just education......

Ok, so I am continuously reading the short page and a half of MS rules,
para 5.D.4, B B and I see that the front suspension can be narrowed to a
"tread width" of B 27 inches. B Now my basic understanding of tread width is
that width of rubber on a tire that has grooves in it. B Track Width, I
understand as the width between center lines of tires on an axle. My front
"track width" is about 58 inches (ie center of one tire to the other tire)
while my "tread width" is about 5 inches as I measure it.

What's correct? My curiosity abounds....
