That really sucks, Jim. Iíd have trouble finding space for all of those weights. I just signed off my CI yesterday and balanced my nose wheel for the first time at around 300 hrs. Still the Vanís supplied tire and tube. As a comparison, it only took 0.25 oz opposite the valve stem to get it within 2.6 g of balance. And yes, my tire has the red dot, positioned at the valve stem.

If I had to add that much weight I'd try rotating the tire on the rim 180 degrees and then see how much weight is needed.

Jim, you can easily spin it up on the plane and know exactly what will happen in the air.

Per my post #70 above where I now have 14 pcs of 1/4 ounce lead weights to balance the new tire.... Today I flew to three outlier airports to test nose wheel balance. Looks really good... I spun-up the wheels a bit more than usual on takeoff and nose wheel was surprisingly smooth as it coasted to a stop. I checked to see if any weights shifted and appears hunky-dory. For now, I will run as is...

Just a quick "Me Too" that:
1. doing a soft field landing and keeping the nose off proved that the issue was the nose wheel spinning
2. using the harbor freight balancer and working until the wheel assembly was finally balanced fixed issue.

I had a Cessna 150 with bad shimmy on takeoff and landing. I took the wheel pants off, and the problem was gone. I worked with a friend who did composite work for the military. He looked at the wheel pant and saw some bad repairs, but the real problem was a manufacturing defect in the trailing cone, too much rosin and glass. He set up a rig to find the center of gravity based on the nose wheel. It took time but fix the problem.
