First time I went to the corner store with a bad tube, found the replacement, installed it and the dang TV worked again! Thought my head would bust from such a feat! 59 year's of age.
We have lug nut indacater's on all axel's. One can tell real easy during pretrip if a lug nut has moved. Heavy oil field truck's on rough road's. Cheap and easy, I like them.
