You guys can do what you want, but BMW officially recommends snow chains only on the rear wheels and only in 17" size for non 'is models and in 18" size for the 'is models due to clearance issues (namely that you cannot mount 17" rims on the front wheels of an 'is model), etc. Keep max speed under 30mph and you won't destroy the wheel wells. However no guarantees that your wheels won't get scuffed.
