Alignment or balance?
I'm asking in this thread rather than in the other. I just got new tires put on my C5 and then had it re-aligned. There is a slight steady vibration now as I travel down the road. The vibration, though slight, is something I don't recall having before I got the new tires and realignment.
My question: Is a continuous vibration due to misalignment, or wheels out of balance?
Thanks.

Most likely, it's a balance problem ... or it could be a bad tire. It's something you want to get fixed before it cups your tires.
What kind of tires did you get?

the the vibration come from the wheel or can you feel it in the seat?
wheel usually says the fronts are out of balance and the seat usually says back ones.

Yup...

It would have to be REALLY out of alignment to vibrate..
OR the tires could be out of round as well. Been there done that.

Vibration is most often a balance issue.
As was stated before, feel it in the steering wheel is the fronts and in the seat is the rears.
Let us know how the balancing turns out.

I agree with the others - vibration=balancing issue.
Is the shop performing a road force balance? This is important because the newer Hunter machines (there are others too - but Hunter was the original and the best IMO) checks for run out of the rim besides balancing. Point is if the wheel is slightly heavy on one side due to irregularities in the casting or forging process and the tire is also a little heavy from the molding process - the run out will verify that. A good tire tech will recognize the condition and break the beads on the tire - and turn the tire on the rim.
My suggestion is to specifically ask for a road force balance.

It is worth asking for - it will make that much of a difference.
Here's a link to Hunter's website that talks about this machine and the technology.....

Thanks. I'm taking the car to Discount Tire Sunday morning. A simple balance took most of the "kidney shake" out of the car but I can still feel it. If this doesn't help, it's time for new tires.

Will let all of you know the results when I have them.
See you on Saturday at Bloomington Gold. (Thats why I am so anxious to get the vibration thing fixed...long trip)
