I'm taking our 2.0D for a trip Brisbane to Canberra next week with a short 2 day side trip up to look at the Snowies (Jindabyne Thredbo).

Temperatures in canberra are al ready sitting at -1C at night but +15C durinh the day. Thredbo is randing from -4C to mid teens in the day.

Im getting conflicting advice about the suitability of the P7 summer tyres. My owners hand book say that they are not recommended for operation below +7C while Ive read other US Canada sites saying below -14C the tyres go roch hard and lose all traction.

+7C seems a bit low as the bottom end of safe operating temperatures. Even Brisbane can drop to below +7C in winter. Any comments on my need to switch tyres for a a 1 week period of cold weather.

Also is the standard engine coolant and wiper fluid already sufficent for sub zero temps.
