Chim,
My tires are loaded with windshield washer fluid. I have to keep them at 30lbs. I spun a rim at 20lbs., so I keep them firm. Actually, this issue is sounding like it is a bigger deal than it really is. I do only have a small fluctuation in "wheel wobble", and I think the dealer hit it when he said the fluid can magnify the side to side wobble on hard surfaces at higher speeds. Quite honestly, after removing the hub, cleaning and retorquing, I'm not too worried about it. There might be a small amount of wear on my axle, but definitely not worth doing anything about. The important thing is that I have learned something out of this process. It once again reinforces the importance of torquing those hub bolts on a regular basis. When I see a potential problem, I look at it as an opportunity to learn more about my tractor. Someday I may understand it.
Thanks,
Greg
