Does wheel truing fix an "out of round" wobble?(6 posts)

Does wheel truing fix an "out of round" wobble?Fez

My back wheel/tire (Open Pro) has an annoying wobble that goes up/down and is out of round. A little unsteady and chatters on high speed descents. Wheel and tire has approx 2200 miles and getting the wheels trued didn't help.

If it is the tire, that's an easy one - replace the tire.

If it is the rim, is there a fix? Or do I have to get another one and build it up again?

I've never seen it work, that high speed shimmy hoppin bo boppin rear wheel stuff is not for me. If it were me I would replace and relace.
Yeah, probably the rim, butFez

is it common for the clincher tire to be the cause of the wobble as it racks up miles and doesn't have the "point" in the center like when new?

Of course it fixes that. Did the person who trued your wheel check to make sure that it was vertically true as well as laterally? Where the rim has a high spot, tighten the spokes on both sides of the flange. Then check again and do what needs to be done.

Frequently an out of round condition is due to the rider bashing the rim in on a pothole or such. This is repaired by replacement, as there is no good way for the spokes to push the rim away from the hub.

Most anyone can adjust out the side to side wobbles that wheels get. Up and down is another story. If the rim itself isn't pretty nearly perfectly circular, you might as well bite the bullet and replace it.

Here's what I would try: First of all, take off the tire. Then put the wheel on the trueing stand and loosen every single spoke until you can just see the top thread so that you have an even starting spot. Now, starting at the valve hole, tighten every spoke 1/2 turn at a time until you just start to get tension into the wheel. Make sure that you're turning the nipple, not just twisting the spoke. At this point, if you find a group of spokes that feel obviously looser than others, your rim has a set to it.
