hi everyone can you help major traction problems on snow ice and wet grassy fields car is running RE050s bridgestones bought the car 2mths ago to tow my caravan all year round i thought, but have got stuck twice once on snow/ice and on the wet grassy field quite embrassed never got stuck with my golf running the same width of tyre prior to buying the a4. i placed an old blanket on the ground and it gripped on that but once clear of it it just started to spin on the grass again, this all on tickover and no throttle will different tyres make any difference.
