Lots of numbers out there.
Most common seems to be 0.03" of runout for alloy wheels.
Anybody have any real world experience on what's too much?
And is it peak to leak, or from centerline?

Measured a couple and most are about 0.07" peak to peak.

0.07" doesn't sound like very much to me. Your tires will probably have a lot more runout than that. Do you have a vibration or balancing problem?

same as above - whats the actual issue? Do they vibrate? Will they not balance? Or are you just being overly anal and trying to find the "perfect" wheels?

How many have you measured? 2? 4? 20?

Trying to find my best wheels to have refinished.
Don't want to pay to refinish a bent wheel.
Also don't want to pay to straighten a wheel that's not too bad.

Why don't you try to give Al Reed or Harvey Weideman a call and find out what is acceptable? They are the wheel gurus.

Take them to the local tire shop and spin them. Most of the new equipment is digital and can measure the run out.

That seems like allot. My buddy owns a wheel manufacturing company and I know for there wheel they sell to the cup series there is max run out of .007 though those wheels maybe going a touch faster.

So I talked to my buddy yesterday when we met for a fish fry. He said .030-.060 Is an industry standard for road vehicles. He builds racing wheels and then the standard shrinks to as little as .007.

Or ask the place that is refinishing the wheels. They should know. Pedrini wheels are soft and are easy to bend. I think I would get the worst wheel to be no more than the runout of the best wheel before you refinish.
