Renault Clio IV Estate 900cc turbo 90pk : I have got these tires not very long yet, so I may add another updated review later on. But the reason why I wanted to write a review is because of an experience I have with these tires from day 1. So we bought our car some months ago and it came with a pair of Typhoon all season 6 on the front, and Goodyear eco summers on the rear. No problems whatsoever with handling. The Goodyears however were 7 years old and started to show missing rubber parts and cracks. And thus we replaced with Nokian Seasonproof 2 after seeing this video. The Typhoons remained at the front. The first experience when I drove off from the tire central was ok. All very silent in the car. So I started moving my steer a little from left to right, and immediately I had the impression as if there was soap on the tires. It swayed like a boat on water. There was no "resistance" or "firm putting back the tires in its place". I didn know what to call it at the time. When I drove up the highway home, I never been so scared. The moment I hit 110km/u or over, the car acted VERY nervous. Like as if the rear was going to flip over, or like it wanted to catch up with the front. 1mm of steering left to right resulted in a huge swaying that made me sweat. The rear showed again no "firmness". Long story short. The nervosity while not touching the wheel is after 10 days slightly less, a sidewind is slightly digested better, BUT the car is still very sensitive to steering, and it still doesn't want to settle firmly after a left/right motion or sidewind. Driving with one hand only is out of the question. I read it's called squirming, something to do with what the tires are made of, the pattern, new rubber, etc. I don't know. Two other tire shops where I asked second opinions looked odd at me when I asked them about it. Like they never heard of such thing as a break-in time. Literally even mentioned on Nokian and other manufacturers websites. The thing is, I dont know how long this is going to last. I dont know if it's maybe also the combination of tires; though the combination before seemed more odd to me than this combo, since it's now all wheels four season tires. Driven now 500km and 10 days with these tires. Changed the pressure a little down and up, currently at 2,3 bar on all wheels (normal is F 2.3 & R 2.1 bar). I might experiment a little with that, or switch Nokians from rear to front. However, I have no idea if it's a good idea to have squirmy tires on the front, and a more stiff tire (assuming it is) to the rear. The car has been aligned meanwhile, error free. Shock absorbers still to be checked though the car is fairly new for such (70.000 km), and it only changed right after the tire swap. I have to admit, taking long corners feels very comfortable and experiencing strong grip. So the rubber actually "grabs" the road when turning, cornering. It's just at higher speeds, as from 90km/u the rear starts to feel like it doesn't have to wheels, but 2 balls.
