On a 26" wheel after 45mph imbalance rears it's ugly head LOL.If it's bad the wheel will hop and adds load to the engine.I balance my wheels (mags) with the stick on weights cut thin and double sided servo tape with the backing left on against the tube or under the linner as well if possible.I had a video of a balanced rear on it's axle spinning for like 4-5 min,reminded me of a fidget spinner.
