So are you saying you'd drive the same in every road condition if you had a "better" tyre? You drive to the road conditions in front of you so if that means take your time or 'drive like miss daisy" then that's what you do.
With good tyres fitted to my car - I do drive the same in most conditions.
As someone else pointed out to you before - The problem with Bridgestone tyres is the difference between their performance in warm weather and their poor performance in cold wet weather. A good tyre will perform almost the same in most conditions.
In the winter - you don't have to be going fast at all on Bridgestone tyres to experience wheel spin, ABS and understeer. Not things I want my performance Golf to be doing! I want tyres I have confidence in.
Obviously I drive a lot more cautiously in extreme weather conditions - even with winter tyres fitted.
