This is good for steel but don't try to use them on mag wheels or aluminum. They won't work. I bought this for the tire on my RV but it wouldn't work if you wanted to use it on the Honda rear tire hanger. I bought the mag whell locks from Autozone. The only thing is they only sell four. But you have five on the car with the spair. So I ended up haveing three extra. Ohl well. The one here for the stell rims is a must . People today just steal to steal and sell your tires. So protect your spare you might needed it some day
