Do these so 'called seasonal' tires have dramatic effect on snow/slippery road conditions?
Absolutely they have! I would not even consider driving without seasonal tires an area, where there is snow more than 2 days in a year. Both my cars have Nokian RSi's.
You already have performance tires, don't waste good money on all-season tires. Get some winter specific tires. The Winter Sports from Dunlop are good.
your car with Z rated tires will definetly perform poorly in snow... go to www.tirerack.com ... check out ,they usually have good deals on winter package... wheels and tires all balanced ready to mount and go ...it will be a better way to go and you can still enjoy your high performance Z rated tires during summer...hope this might help ...
