rims with spin-on center caps, HELP!! Options

[ryguy1231]

I bought 18" Velox VX6 rims, and the center caps spun all the way on just fine. After I had them balanced at my local shop, a couple of them get really tight before spinning on all the way to hold the plate in place...so tight that the wrench broke trying to get them on all the way. They said it is because they use cone-style balancing which probably stretched the alloy just enough to mess up the threads. Has anyone else had this problem?

dunno man. I've got vx6-r's but they came with push-in type caps. press and go. and they stay great too, dunno why velox would have switched to the screw in...
