Well we have seen cracked and broken wheel rims before but not many as bad as this. It is a surprise that the tyre has remained inflated, let alone on the rim, and made it to the VTS for its MOT. To their credit the owner was aware of the damage to the wheel, but had not bothered to get it changed as they had lost the wheel nut key.
