“You should ponder selling it if you need to use snow chains on it”
Snow chains grip on ice(of the just rained then frozen kind) where rubber just doesnt.
Ive had occasion to use chains on a 4×4 in the past – defenders are far from unstoppable. a good driver can make them go well but they are still technically only 2 wheel drive – its just 1 wheel on each axle that will turn – the wheel without the grip normally – bit of jiggery pokery with the left foot and your brake can get you some traction at times.
