Bandsaw Tires

So there I was, trying to tension the 3/4" timberwolf blade on my
Boice-Crane (B-C was, apparently, was owned by the Wilon Group, which
now owns Jet, Powermatic, and Performax) 14" bandsaw. New Polyurethane
tires, installed with only my recollection of the instructions from
Suffolk. I did not glue the tires on. I adjusted the tracking by
turning the lower wheel by hand (with the saw unplugged!) I kept at it
until the blade was centered on the tires, which have only the barest
hint of a crown. The blade stayed centered when I turned wheel enough
to rotate the blade all the way around (I saw the weld pass the upper
guide, twice.)

Anyway, I may need a new tensioning spring. I tensioned the blade until
the pointer on the back of the saw was just a bit past the 3/4" mark,
and backed the guides away from the blade (on all three sides, both
guides). Spun the wheels for another turn of the blade. So far, so
good. I closed the wheel cover, and hit the power switch. The saw came
on, and after a few seconds, spun up to speed. There was a noticable
side-to-side vibration in the blade. The saw didn't vibrate much when
running, just enough to have a nickel-on-edge fall over after ten or
twenty seconds. It still deserves a new belt (link belts don't work in
7/16 pulleys :-( ). I still have Suffolk's instructions on tensioning
the blade (short version: start at rated tension, reduce tension until
the blade starts to flutter, increase tension back until flutter stops,
and you're good to go), so I thought the blade needed more tension.

Anyway, I was around turning the tension wheel to increase tension some
more, when a loud noise came from somewhere within the saw. I hit the
power switch, waited for everything to stop, unplugged the saw, and
opened the door. The lower tire had slipped off the wheel, and been
carried up the return a little ways, where it got caught, and nearly
sliced in half crossways.

So I'm thinking I need glue. The saw manufacturer recommends rubber
cement, but that's for rubber tires. Lonnie Bird uses 3M
Weatherstripping adhesive. Mark Duginske recommends using cement if the
old tire was cemented.

Anyway, what do the rest of you use?

It will take me a little while to get a new tire, and get it installed
(and maybe even glued on), so in the mean time, about two board-feet of
beautiful quarter-sawn white oak will be planed from 7/8" down to 1/2",
instead of being resawn. Oh, the humanity! The $6.50 in lumber that
could have been half-saved!

I recall heating tires in water 150° 15 minutes then stretching over ledge on
rim of Rockwell 14", no glue. Old tires weren't glued either.

I bought a new 14" Delta this summer and replaced the tires with the
Urethane tires I ordered from Ibarra in Fla. They are great. They were
VERY tight and I had to heat them up in hot water before installation. I
am very happy with their performance so far and have noticed now that
the local Woodcraft store here in Boise also carries a urethane tire
(Blue color vs. Orange). Both cost 22.00 each. I have tried glue on the
Delta tires (used a 3M rubber cement) but find the urethane behaves
better.

Pliobond. Comes in a convenient little bottle from the office supply. But
it looks and smells an awful lot like solvent based contact cement.
Pliobond was recommended by my local Delta service center.

I told Suffolk a 14" saw and they sent orange urethane tires that ended up very
tight after cooling.

Anybody ever tried/used the urethane tires I see advertised?
