my brother has a flat right now, and we can not find the hole the nail was in (he took out the nail... yea...) so instead of tryin to look for it while the wheel is still on the car, we decided to take it off, but when l looked at my assortment of tools, none of my sockets fit the lug nuts, so tomorrow mornin we're goin out to get a new socket

does anyone know the size of the lug nuts on a 05 scion tC?
(and if it really matters, its the rear wheels... cause some cars have different sizes in the front and back...)

it the wheels and lug nuts are stock from factory. it is a 21mm socket.
