Actually It can be difficult to undo the wheel nuts if they’ve been on a while. A spray of warm water helps, which is why many Morgan owners keep a dog in the car
Pour hot water on the nuts and they come off easily. I keep a tin bucket in the car so that I can drain hot water from the radiator at the roadside. I jack up the front of the car the do this. Sometimes I have to whack the radiator drain tap with the copper hammer, but it saves damaging the wheel nuts. I have to carry a gallon of water to refill the radiator, together with a pint of anti-freeze. It pays to be prepared”
