I'm not a great fan of VW beetles, especially the two abandoned in our yard (Roger can't bear to part with any vehicle he's ever owned) but I have to admit it is the only vehicle that will go on any mountain track anywhere we've been, even the deeply rutted or boggy tracks which are our lot now that NZ Electricity Dept (no longer extant) maintains them, and not bothered by snow either. My Morris mini rarely let me down though I used chains on that in snow.
No, nothing to do with tire inflation or chains.It's when a vehicle has been parked out overnight in extreme cold, and the rubber of the tires freeze, such that there is an imperceptibly flattened area where the tires rested on the road. When you start driving the car, the flattened area on the tires cause the wheels to bump and clunk along until the road friction heats them up again.... "square tires". It seems to have to be -40 C or worse for this to happen. What a country!

The car really seemed to jump up in the air.johnw
