Purchased a new set of wheels & tires for my 05 STS. Decided I wanted the TPMS installed in the new wheels also. Go to the local dealer and order 4 new ones. Take them to the wheel dealer. Lo and behold the TPMS comes without the mounting nuts!! Now why would anyone sell a system that needs the nuts to mount them not include them with the part :cookoo: So I go back to the dealer, of course he doesn't have them in stock and must order them. Says he'll have them next day. 3 days later I'm still waiting. This really sucks! So I am pre warning other buyers wanting to get the TPMS sensors for the wheels, DON'T forget to make sure the parts guy gets you the NUTS also! :banghead:
