I have the proxes 4 on my Protege 5 in the size you are interested in. I really like them, but have only put about 2000 km on them. They seem to perform really well in the rain. There was no hydroplaning at all in the water that had pooled in the ruts of the two lane highway I was driving on.
Pros: Quiet Ride.
Tons of Grip (with no squealing, and believe me, I've tried!).
Seem to perform well in the rain.
Smooth ride.
They look cool. (It's minor i know, but they do look cool!)
Cons: Treadwear probably won't be the best. (but most likely no different that the other tires you are looking at)
The sidewall seems a tad softer than the stock dunlops (but,I changed those out pretty quickly)
I suspect the softer sidewall gives a nice ride, but sacrifices some handling.
Overall, I really like them and this recommend them.
