Swap wheels & tyres front to back?

[Chablonski]

I know that this is probably wrong but can I do it. I want to swap fronts to the rears, having a problem with one of the fronts has a inner buckle, just can't afford to replace at the moment. Wheel wobble at 60 mph. The fronts are 225/40/18 and rears are 255/35/18. Ideas please ?

Spare wheel.

The spare is a different type, the wheels on the car are MV2

You cannot swap front ot back as they are different size and offset wheels, buckles can be straightened out for not much £.

It doesnt matter if the wheel is a different style as long as the tyre is the correct size. You should not fit the rears to the front as you could get tyre to suspension or inner arch contact at full lock.
