Re: [ihc] Tire & Wheel Questions

12.5 width vs 15.5 width? It really depends on your rim width. I run 33
(tall) x 15 (rim size) by 12.5 (tread width) on one of the scouts. The
offset of the rim is not part of the tire size, but rather determined by
where the mounting surface is found in relation to the inner/outer surface
of the rim. My wheel mounting surface is half way between the inner and
outer, and my rims are 10 inches wide.

This got discussed here a few years back, and I don't remember whether the
"zero" offset is measured from the center, inner, or outer rim surface.  I
prefer to have about a 20-25% narrower rim than tread, but no less than that
because I worry about losing the bead at low tire pressure. I don't know if
that's justified, but I worry anyway, usually out loud so that my wife will
have something on which to focus while I worry about other things.
