Finally I can provide some feedback for anyone wondering how these tires perform in the winter snow and ice. Honestly, after reading a number of posts where people were critical of tires of this type I expected handling just a bit better than an ice-skate... (IMHO) these tires did a whole lot better than I expected. I had a number of unplowed side streets with 4-6" of snow depth to navigate in the early morning as well as a combination of slush and iced over roads and I had no problems to speak of.
Owner reviews for tires
I have had the proxes 4 on my 24v 2.8l for 12k miles now. Wear has been ok, would have been better if I had bought a seperate set of wheels/tires for autocross. I have not driven them in the snow yet so no idea how they will do. They do handle rain pretty well, and overall Im happy.
i had those on my porsche, very very nice tires, but then i only got to drive in the snow once with them, seemed fine, i didn't have any problems with them
Don't know about the Toyos but the PS2'S are great. They handle excellent in the rain and in the dry. High Speed stability is excellent as well.
based on my own prior experience.. skinnier tires are better in snow/slush.... so I bought a set of 205 50 17s myself... Dunlop Winter M2s for me!
Yes, they'll start talking when you reach their limits of adhesion. Not as loudly as the F1s, but at pretty much the same point (just as they're starting to let go--which seems to be fairly gradual and predictable).
I just ran a track weekend at Pocono Raceway with my PS2's, 245/35/19. They performed extremely well for a street tire.
The PS2s have a much stiffer sidewall than the stock Goodyear F1s, which is exactly what I was looking for. No noticeable tread squirm while cornering and sharper steering response as a result. Of course, this also means they provide a less cushy ride than the F1s--the surface of the road is communicated much more readily to the cabin. The PS2s also produce quite a bit more road noise. Driving on grooved/textured highways was much noisier than the F1s. The tread pattern also produces a tendency for these tires to follow grooves in the road, which was never an issue with the F1s. In terms of overall grip, the PS2s are outstanding. I took several corners at speed in the Ozark Mountains, and the PS2s showed no signs of letting go. Very confidence-inspiring. They're easily as grippy as the F1s, and actually felt as though they were superior in this regard. Wet weather performance was easily as good as the F1s, much to my pleasant surprise. I drove in conditions that varied from a light sprinkle to a heavy downpour, and the PS2s continued to perform as solidly as they did in the dry. I plowed through several puddles with not even a hint of hydroplaning.
My all-season tires however, and worn for the path. They are still drivable, but I will definitely be replacing tires before winter.
I am running 205-50-15's Kumho and it is horrible!!! Luckily these tires I had laying around and no "real" money was spent on them...
