Do the 14" Bruiser wheels have true beadlocks or is it just cosmetic? Mine turned up today and I noticed they had a series of studs all around the wheel. I've never had a beadlock wheel before so don't really know anything about them. I tried twiddling them with a hex key and not only were they really easy to turn but the finish seemed to deform really easily so I'm wondering if they're just little cosmetic studs?!
