Most definitely get some if possible. When i had my 4x4 i had an extra set of wheels, shod with studded tyres, which i admit are a bit difficult to get. You must have all tyres the same. The new wheels can simply be plain old cheap steel rims, then just label em i.e FOS, FNS, ROS, RNS then, if ur lucky enough to have an impact wrench, just wizz em off and on when necessary. Takes about 10 mins.
