what do you run then mate, i came very close to a 6 feet ditch last night
If you came close to a 6 foot ditch, I am sorry to say but its nothing to do with you having the wrong tyres, it was either:
Your current tyres are shot
You were driving too fast for the conditions
You may have hit a greasy / icy patch
Or you were driving too fast for the conditions
Or maybe a little bit of all.
For the winter you definitely need to check you tyres have tread on them >3mm, but also you need to adapt you driving, roads will be colder, tyres will be colder, brakes will be colder, you can't hoon around as much, like you may do in the winter!
