Put a steel nut against an aluminium wheel, add water, and you have made a battery. That is not a figure of speech. Two different metals in contact with moisture between them set up a small electrical current, and the softer metal corrodes preferentially. On a wheel that means the aluminium around the nut seat turns to a white crumbly oxide that swells as it forms and grips the nut from all sides.
The result feels like a seized thread and is nothing of the kind. The nut is being held by the wheel rather than by the stud, which is why heating the stud does not help much and why brute force tends to lift the seat material and damage the wheel. What works is releasing it squarely and steadily so the oxide crushes rather than tears, then cleaning the seat back before anything goes on in its place. Get that bit right and the replacement sits properly and torques correctly.
The car does not have to move, which is just as well, because usually it cannot. A wheel that will not come off on Mile End Road is not a problem you can drive away from. Old tyres leave Spitalfields, Commercial Road and E1 with us, every time. You watch it happen in Aldgate East, or at the kerb in Stepney. E1 takes in Stepney and Shadwell, and we work the lot.

Cars in E1 tend to live on the street rather than under cover, and years of damp against an alloy is exactly what sets this going. It is a slow problem that arrives suddenly, usually the day somebody needs a wheel off in a hurry. Because the fix is a tool and a technique rather than a workshop, it happens wherever the car is standing.
Aluminium oxide, formed where the steel nut meets the alloy. It expands as it forms and grips the nut from every direction, which is why it feels like a thread problem when it is not.
Cars that have not had a wheel removed in years are the worst affected, because nothing has ever disturbed what is building up in the seat.
Traffic around the Royal London is constant and there is nowhere to leave a car with a wheel that will not come off. We work at the kerb, so nothing has to be moved first.
Because the two metals plus moisture corrode the softer one, and the oxide that forms takes up more room than the metal it replaces. The nut ends up gripped by the wheel.
It can, which is exactly the problem. Load applied squarely and steadily crushes the oxide. Load applied roughly tears material out of the seat.
Yes. A replacement nut torqued onto a crumbling seat will not hold its figure, so the seat gets cleaned back before anything goes on.
Yes. Pull into a safe spot off the live lanes, tell us exactly where you are, and we will come out. Typical arrival across E1 is 30 to 60 minutes.
If they have had the same years and the same weather, quite possibly. Say so on the phone and we will bring enough to do the set.
