Was that tire damaged? We had a rear tire repaired with a boot patch once, and it unbalanced the tire so much that it acted the same way on a 100 hp Deere, If the unbalance is bothering you, a set of new tires might be in order for it. Check with your local farm tire dealer, I think they can be balanced to stop the bounce now. Good luck!

Could you jack up the affected wheel to see if the rim is bent or if the tire is bulged? if you rotated the tire slowly and looked at it from various angles you might see the source of the problem. I'm not familiar with that tractor, but from a picture it looks like you might need one person to spin the tire while the other looks.

A bent rim or bulged tire might not be an issue at low speed, but at higher speeds could affect ride.

Let us know what you find.

Is rear tire radial or biased ply. If biased ply after sitting for a while it can take many revolutions for tire to get the flat spot removed from sitting corrected especially if inflation of said tire is low below spec's.

Is the rear DIFFERENTIAL LOCK stuck on, by chance?

Perhaps the tires are filled and have tubes. If theres a pinhole leak in it, its possible that air or fluid leaked thru and formed a captured "bubble" between tube and tire. That could cause many pounds of imbalance and sure lump it up a bit. :confused3: ... Is there ANY fluid seepage at the valve stem?

Does the tractor have more than one right rear wheel?

I wonder if someone put water in for ballast and now it's frozen. What have your high and low temps been like up there in the Great White North?

Don't know about tractor tires, but most vehicle tires will develop a flat spot if left sitting for a long time. 12 lbs may not be that low, for a big tire. I'd find the correct pressure before pumping it up a lot. My L3400's rear turfs run 13 lbs. Just driving it some, assuming you don't see an obvious defect, might "fix" the problem.
