I have to say that the ateca is the worst vehicle I have ever driven in snow by a mile. Probably less than a half inch of snow and it just spins the wheels. 18 in falken tyres. Absolutely no control whatsoever. Scary driving any more than 10mph. Even an old rear wheel drive ford granada with bald tyres is better. Trust me.
If your going to fit inferior rubber, expect the consequences, Bridgestone are standard fit on all UK models,.
