"You need a driving lesson" term has been taken for granted many times here. I am not sure how many driving lessons you took go become an expert. I work with a team who do vehicle test for living and most of them has winter tires on their daily drivers and this is for a reason. Can you recommend a driving course to improve daily winter driving for professionals who already have grade 3 license to test vehicles on a track.
Aggressive is greatly subjective. And you are very happy with your Pirelli Cinturato P7 stock tires which many people here would very well disagree. What is aggressive to you, might be normal to me.
Thats the reason for performance winter tires existence which strikes a balance between dry, wet and snow with a good speed rating.
Not claiming to be an expert beyond the 35 years of driving experience I've had in the Midwest winters with many different cars. I can speak from experience. I never ended up in a ditch unless I was messing around.
Not happy with the Pirelli's, just surprised they fare better for me compared to people who say "they suck". It's an average tire for sure, we'll see how they fare after 10K miles. Had some Kuhmo's that were very good up to about 12K mile mark, then they were horribly loud and had much worse wet driving characteristics. So bad, I took them off after 15K even though they still have a good amount of tread left.
Performance Winter tires are an oxymoron. Some are certainly better than others in the dry and above freezing, but they won't compare to a great A/S tire in the same conditions.
