4th gen wheel question

[RichardP]

how would one tell that a wheel has used up it's life?

You basically can't tell until there are signs of cracking. The problem is, most people don't look closely enough or often enough at their wheels to find cracks before they become a serious issue.

I have fatigued four sets of wheels: A set of three piece 4-lug wheels (that I bought used from Fair), a set of two piece welded Centerline wheels, and two sets of Konig Villians. So far, I've caught the failures before there was a problem on track. We run the Z06 wheels on the CMC cars. Those are pretty durable wheels but there was an AI f-body in California that was wiped out when one of those wheels failed on the rear. I run the the Enkei rpf1 on my car. I've heard of people with fatigue cracks on them but I've never seen it in person or in pictures.

I've attached pictures of some typical fatigue cracks that people should be looking out for.
