[QUOTE="Speartip, post: 454699, member: 23341"] Today I performed a science experiment called "Bi-metal electrolysis corrosion"! The experiment was a resounding success unfortunately . [ATTACH type="full" alt="2E7D1C49-20BC-4F74-AA0E-EC0692709BE5.jpeg"]123430[/ATTACH][ATTACH type="full" alt="D4EAC5F7-44C5-4F6C-8761-3DE8F72E79EB.jpeg"]123431[/ATTACH][ATTACH type="full" alt="C3F0F930-0FD8-4DD6-A308-2D892F3770D0.jpeg"]123432[/ATTACH] The PO had installed metal valve caps on aluminum valve stems . I knew they were metal but didn’t think to much about it till today. It’s been a couple months since tire pressure was checked . Had to pull out pliers to attempt to get cap off . First one came off . The next one ended up busting off the valve . Totally seized . So if your running similar setup , anti seize would be highly recommended . New wheels will be here soon so going with traditional rubber with plastic black valve cap . Ran rubber for 30 years in Edmonton on multiple vehicles and never got side lined by a messed up valve or cap . Didn’t even attempt other 2 tires cause don’t want to break off another valve .
