I too have noticed "shimmy" when Aircraft Spruce changed over to the Chinese nose
tire (Shin). Keeping it inflated to the max helps a lot. (I replaced the friction
pad last year too, which helped a lot. 3000 hrs.)
Where does one get a balancer?
Are there alternative sources for this tire. Desser? I forget the size of the nose
gear just now, but I see Desser has oddball sizes.

Would be worth paying a little more to have the smoothness.

The Chin tire costs about $18. Aircraft Spruce has a premium tire for
$46.00.

The A&P that balanced my nose wheel used a rod that slid through the inner
races. The rod had two conical shaped attachments that screwed up against
both inner races. The outer ends of the rod had bearings that rested
between two tripods. After setting the wheel in the jig the tire's heavy end spun
down and by trial and error, he was able to stick on the exact weight onto
the rim to balance it. I have seen these wheel balancers I think, in
Aircraft Tool Supply company catalogs. I rolled out the tire over a yard stick
and found it only rolls 34 inches to complete one revolution. If you factor
in how many revolutions that tire makes between 65 mph and even 20 mph, it
wouldn't surprise me if the four ounces out of balance my wheel was and
considering centrifugal force dynamics, that four ounces could factor out to
be several hundred pounds of out of balance force.
