Certain rims are impossible to balance, I think I got a set. I noticed they were always out of balance slightly and I suppose I got used to it. Well just last week I put the chromies back on and they were out of balance, so I took it to the shop to re-balance them (who knows how many times I've done this) and they STILL are a little shakey at times at 60mph+. City driving is fine, car is perfect, but once I get out on the open road there will be times of some shuttering. I talked to the mechanic on the phone just after I had them balanced today and he said he did his best and its hard to balance my wheels because you can't put any weights on the outside. I knew this, many shops tell me this, and he told me he'* seen it a few times before. He apologized and I said no prob.

My question is what can I do to try and get them the best I can? The weights are placed inside the rim well, if I could somehow move them as far to the outside as possible would it help? It gets annoying, but then again maybe my car will settle in after a week of these rims. This aways happens each summer and I seem to forgot about it somehow....

Did they check for water or fluids inside the tire? I had a tire once that "couldn't be balanced" until I took it to a buddy'* shop, and we dumped the still fluid fix-a-flat out of it.

Holy crap! Just remembered I rotated a tire that had a nail repair to the front!

Might be why I'm noticing it more this time around....that tire was in the rear last summer. I'll check into it.

Kyle, have the shop dismount the tire from the rim, and rotate it 180° before remounting. That might do it. The tires themselves aren't perfect, either, and this might help even it out. After they do that, and re-balance, it may be better.

You could also have the shop check the wheel itself to make sure its within spec -- and I agree about rotating the tires 180 degrees and seeing if that helps.

Not to sound silly but your tire pressures are all correct right?

They are not bent are they?

Problem solved (sorta):

They use patches (not fix-a-flat or anything related) so there was really no extra weight. Well they rechecked the balance on all wheels, rotated front to back, and it turns out there was some chrome corossion on the left front (now on left rear) which added about 2 1/2 ounces. So now that its on the back everything is much better and in the meantime I'll try and file off all the corossion...but what can I use to prevent moisture from getting back in those spots?

ever heard of a road force balancer? checks for imperfections in tires and such?

Just fix the problems before you dump them off on me
