yup i know how that goes. since the cold up here in the ak is going up and down...usually when the cold sets in for the night and my truck sits i usually go to start it up my light would come on and one tire would be low. jus check all tires including the spare before taking the truck in. also keep ur valve caps on because road grime or rocks can damage those stupid little expensive things and its a hassle just to take it in for that stupid light!
