nope.... the origonal wheel nuts will not have the same pitch diameter (bottom of the wheel nut hole) as the new alloys..... you need to use the correct fitting kit that came with the wheels or even go and get a fitting kit from an alloy wheel supplier.
if you fit them with the standard wheels nuts you can create pressure points on the nuts and even snap them off.....
but yea, use one locking nut and three wheel nuts,.
