I was just checking a spare set of wheels that I have and the runout is around .070 . Is this ok ?

Bill you are trying hard to get reason to buy some new wheels aren't you? I just replied to this on drr. I know you found some super lite wheels you want right?
This from the guy who spent 4 hours maching on some used caliper to save 2 whole pounds off rear of car. Heck I drilled the holes to get the air out of them.
I don't see how .070 could be big deal.Think about all the crap the tires does shape wise during a run. Is it wheel or mounting maybe tightened some before centeredmwould only take .035 off one way to get the .070 you have that pretty small on 15" wheel.

I just made the first race of the season (6 passes) with a brand new set of 2585's that had at least 5/8" difference and everything was fine.

Maybe my fault on confussion.Bill's post is about the wheels runout not the tires rollout.
-
I've never checked the runout of a wheel before. How do you do it?
Sorry for my confusion.

throw it on the balancer without the tire, any visable run-out or if the rim requires too much weight to balance, I'd replace them.
I spent a season chasing a handling problem where my altered would start bouncing and break loose at 1000ft. The season before I'd a "moment" in the shutdown where, due to my fault the car got out of shape and bounced around landing really hard on the rear tires. Turns out I'd buckled a rim and bent a MW 35 spline shaft. The shaft was chucked up in a lathe and had about 1mm eccentricity at the flange.
So if in doubt replace, :)
