Admittedly, I switched to PS4s for driving on the road exactly because of the stories I've heard about hairy handling in the wet on Cup 2s.

 

I have PS4 in all my cars, even one car where the tires are more expensive than the car itself.

I was sold after a few years ago I saw the One Lap of America results on day 1 at the wet skid pad and the tires were pulling almost 0.9g in deep standing water. A week later they run the dry skid pad after having been in multiple time trials and thousands of transit miles, and the same used-up tires were pulling 1.3g.

For track use, switch to a better track tire than the MPSC2, for street use the MPSC2 cannot keep up with the P4S, to put heat on the MPSC2 at least in America, it means breaking every possible traffic law.

 

Are you guys finding (1) far better rain performance, and (2) better tire noise with the PS4 vs. the PS2?

 

I wonder why you say "constantly?" After the first instance, aren't you slowing, seeking a speed at which the problem goes away?

 

that’s the freaky part, it’s not consistent

feels awesome at 50mph on the interstate tho

 

For even more "fun" in the rain, try Trofeo R's.

 

Hi Bob, how have you been?
You are right about that, maybe I am just getting wimpy in my old age, but have been on far worse than the Cup2 in the wet that's for sure!

Yes for sure.It is a much better all around tire than the PS2. I have switched to PS4 and not going back.

 

What size PS4’s did you end up with?

 

I find the Cup2s perfectly acceptable in even heavy rain, street or track. I agree with a prior poster that it depends heavily on what your prior experience is. I'm quite comfortable with a car sliding a little and expect movement going through standing water, all predictable enough. Maxx2 even better.

 

I had a friend's 991.1 GT3 for a couple of weeks back in February. Ended up having to drive home on the 405 and the 101 during rush hour in a downpour of cold rain. On a set of worn/hard PSC2. I drove her conservatively but I was still very wary about hydroplaning. That said, I never felt so much as a tug on the the steering wheel. As long as you don't blast through standing water you'll be fine.

 

I drove my GT4 with Cup 2’s often in the rain and thought they were great. I’m sure temperature makes a big difference and maybe at 40 degrees it’s a much different experience, but it rarely gets that cold in Houston. I’m guessing with the GT3 it’s going to be much more of a “things are great until they aren’t “ in the rain. I’ve put Supersport 4S’s on another car and they have phenomenal wet grip.
