I have a Rover 45 and want advice on removing wheel nuts. There is one locking nut on each wheel that has its own tool -take cap off, fit adapter and remove with 19 mm socket-dead easy. Other 3 nuts seem to have a loose stainless outer shell . The wheel brace has enlarged itself due to some tyre fitter overdoing it. I tried a 20mm socket- Too big
19mm socket -To small. . If I have a puncture ............Help.
