Forget the wheel changing kit supplied in your boot, an impact wrench will have the rim off in seconds. This tool runs on 12-volts and can be powered via the cigarette lighter socket or directly from the battery via an adaptor. It comes with 4 sockets to nuts between 17 and 23mm and has a 3.96 meter lead to get to any wheel easily. This device is rated up to a torque of 115lb/ft which should be good to remove most stubborn wheel nuts with ease.
