Not the nuts to blame, but in my application the only thing I could use was locknuts. The stock nuts were outside too large (21mm) for my rims which require a 19mm (3/4") M12 x 1.5 threaded nut. Check your rims before ordering as trying to get M12x 1.5 3 Finding /4" (19mm) hex nuts is a best Saturday challenge at local auto repair shops. I finally found what I need everywhere at the Costco tire center.
