can any one tell me can you use wheel,s from a car and put them on a caravan, i,ve got a twin axle caravan and the wheel,s are so slim , i thought possibly a car wheel.also i have noticed the caravan has no suspension accept for the torsion rubber,s in the axle .by the way my caravan is a 1991 year. will this make a difference to the caravan being towed smoother with suspension .
