The rainsport 5s in question are on initial impressions (1200km so far) a bona fide premium Tire in the dry, gone are the days of the soft sidewalls. The Tire provides excellent turn in and high speed stabillity. In the wet is still king though I have never tried nokians. Don't be fooled reading tests that other premium are equally good in the wet. In deep water and poor road surfaces the uniroyals offer a sense of security above anything else.
They are also less noisy but for some reason maybe unrelated to the tires the fuel consumption is marginally higher.
Also the experience from the 3s taught me that in very light snow to they are drivable I am not suggesting they are as good as all seasons but they provide some traction and don't have the typical wooden feel of summer tires.
All things considered a great Tire.
