Rear Wheel Wobble

[rops84]

Thanks Ed; I more or less did that yesterday and found the tire moved but not the wheel. How does a tire get out of round especially if it was used one year then sat in the garage the next while the bike was rebuilt? Could the weather changes affect the rubber enough to cause this?

this.


A tire sitting for a year in the same position is bound to be disfigured and lose the perfectly round shape...
Did u move around or spin the tire at all in that year?
No expert, but even when storing a motorcycle over winter isnt it a rule to spin the tires every few weeks and not let them stay directly on cold concrete?

Maybe try to find another tire to put on ur rim and give it a try?
If the wobble goes away its the tire, if it does not it s something else.

just a tought

Thanks Rops, I'm looking to get a new rear tire in the next couple of weeks

Weird. My 850 sat a couple years with no adverse effect upon the tires. The airbox boots however, did shrivel up. Just a few years old. Attributed to ethanol.

You didn't accidentally fill your tire with ethanol gas did you?

I'm glad you're getting a new tire. One suggestion I'd make...and this is based on not reading some replies...spin the wheel and see if the rim spins w/o a wobble. Then you can narrow it down to the tire and/or the marks on the rear wheel tensioner. Ride safe.

Was the tyre fitted to the bike while in the garage, or was it off the bike? reason for asking if left under inflated and fitted to the bike for a long period of time on the side stand, could have deformed your tyre a little, as you mention best way would to be to replace it for piece of mind. ( just noticed Rops had beat me to it) sure you'll get it sorted.

Wasn't pure nitrogen, though. I think it was the more-common 78% blend.

Good point about being on the side stand. Long-term, my bikes have always been on the center stand. Mainly that was because they take up a little less space that way. And my garage floor is smooth enough that I can slide them around when on the center stand. But it does take most of the load off the tires. So that's a possible difference between my 850 sitting a couple years with no (tire) problems, and other bikes possibly taking on a permanent deformation in the tire after spending an extended time on the side stand.

Took it out to Iron Pony today and they said the wheel wasn't properly balanced (thanks Williams Vintage ). They re-balanced it and I'm going to put it back on tomorrow to test. If it works then great; if not, they said to bring it back and they'll put a new tire on it.
