Thanks shark but I have 3 sets of newish wheels all with the same problem so they cant all be broken.

Thanks tommy I haven't shopped with amain before (never had the need) but seeing as they aren't in stock anywhere else that I've checked I might grab one of their wheel balancers. I hope this doesn't open up a can of worms, I did a quick search on here and didn't come up with much on the topic.
