As far as fitting inside the wings, if you mean will they rub then possibly, but only a bit at the very bottom corner of the lip on the front wing. The usual thing to do is to re-profile the lip bu cutting some material away and bending up a new lip.
If you are talking legally covering the wheels, then perhaps not, they would stick out and the plod would not be happy. Simple solution is to choose some aftermarket wheel arch extensions that will cover. If you like the plastic 'special' arches that should be on your car (84) you can get ones that are just like them but wider from minispares ect.
Another thing to take into account. Can you fit 10's? If your car is an '84, it is right on the year that the 8.4 inch brakes where fitted as standard to all minis. From 1984, 10 inch wheels will not fit on a classic mini without modification as the front brakes are too big. Do you have standard front discs?
Oh and welcome, and this is in the wrong section
