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.

Subject: GL 11 FT nose wheel.
I have always had a vibration from my nose strut and as the tire wore down
it would become even more noticeable. When I related this to an A&P he
asked if I balanced my nose wheel? So I decided to purchase a new tire, mount
it and have it balanced. This tiny wheel took well over four ounces to
balance!! Another hint is that Chin tires are notorious for being out of round
so be sure to check for the tire being out of round. After installing the
wheel assembly and test flying the plane, for the first time I felt I was
landing on glass!!
I have been reporting on my new Blended Foil prop and was able to
adjust the hub to get it up to 2750 RPM. After making that adjustment the new
prop had so much P factor I could hardly keep the plane on the center line
when I added full power. Witnesses say the plane only rolls a short distance
before it appears to leap off the runway. After take off I have to apply
full right rudder and aileron to keep the plane and haven't seen that since I
flew my little 215 Hp S1S Pitts Special. The increased cruise performance
appears to be keeping in the added 15 to 20 mph ground speed along with a
higher rate of climb. With these warmer temperatures I have been noticing
that my oil temperatures have been running hotter than usual with this new
prop. Before the new prop my oil temperature ranged between 190 to 200
degrees during the summer months. But with the upper seventy to low eighty degree
outside temps I am now flying in I am seeing oil temps in the 200/215
range at altitudes below 3,000 feet. I find slowing the plane down before
entering the airport traffic area to 100 mph the oil temperature shoots up. But
if I keep the cruise up to over 140 mph and slow the plane down in the
down wind the oil temp doesn't shoot up as quickly. I haven't been able to
figure out if this is because the new prop works the engine harder or if
because of the design that less air is blown into the cowling. One other hint
in keeping cylinder and oil temps down on climb out is to maintain full
throttle on injected engines. There is a jet in the throttle body that dumps
extra fuel on full throttle. To reduce power use your prop control on climb
out. After take off and reaching 600 feet I adjust the RPM back to 2550 RPM
and climb another few hundred feet and adjust it to 2450 rpm before setting
everything when I reach my cruise settings and altitude and have found
that keeps my temperatures cooler.

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.
