re locking lugnuts tire rebalance in article apr skcla monsanto com mas skcla monsanto com writes if you put a locking lugnut on your tires do you need to have your tires rebalanced john mas e mail address mas skcla monsanto com well it depends on what kind of locking lugnuts you have my previous car had locking lugnuts that weighed about oz more than the others the locking lugnuts were factory equipment and according to the factory service manual after tire balancing the technician mechanic was supposed to put a oz counterweight on the rim opposite the locking nut i always had vibration problems with those stupid lugnuts since no one ever did the service correctly i eventually got rid of the locking lugnuts and replaced them with the standard lugnuts unfortunately i found out about the counterweighting technique months after i got rid of the locking nuts my present car a saturn sc has locking lugnuts that i bought at the dealer and are made specifically for the saturn they have been made to be exactly the same weight as the non locking lugnuts said so on the package and i verified it myself i haven t had any vibration problems with the tires at all due to the nuts in of ownership i did have some other vibration problems but it was due to a poor job of tire balancing tom
