I've looked through all the old threads (that I can find anyway) on gear leg vibration. Here's my problem: A year ago I converted my 9A to a 9, including adding the capability for larger wheels/tires. I flew for the past year or so with both small (standard) wheels/tires as well as ~60 hours last summer with 800x6 tires and had no issues. This spring I went to change out the standard tires for the larger ones and encountered horrible gear leg vibration. Upon swapping back to the small tires, the vibration goes away. No known change in the big tires - they've been mounted on the same rims as last year but just sat over the winter. I checked the balance (static) and they are still balanced. I looked at the roundness while they were on the axles and jacked up. Best I can tell, out-of-round is not an issue. I swapped out all the bearings just in case it was a bad bearing, and no change. So now I'm running short of options (that I can identify) and looking for suggestions on what to do next. I have considered adding stiffeners to see if that helps.
The conundrum for me is why these wheels/tires worked fine last year but seem to be a major problem this year.
Any comments/suggestions welcome. Meanwhile, I'm flying with the small tires that don't give me vibration issues.
