I just took my ZII out on Pacific Raceways on a rainy day. First off, the circumstances
The rain put a bit of a damper on any tuning I intended to do. The car was balanced enough after the first run that I didn't bother modifying the tire pressure. I thought it would be near impossible to get accurate readings on a wet day when I basically parked in puddles.
Overall the tires and car handled damp conditions very well, and very predictably. At least on par with the ZI. In deep water they wanted to hydroplane around 70mph, which I'd say is a bit earlier than the ZI did.
In turn 3B if I went in a little fast I'd understeer just a tad, and in the long sweeping turn 8 you just play with oversteer the entire time. In both cases I could feel them break away, but they did so very gradually, and it was very easy to keep control. Certainly no snapping. braking going into 3A I swear they provided more grip than the Z1 ever did in the rain. But I've never run a Z1 at pacific.
Every other corner the tires held stronger than I wanted to take my car through them. Not a good metric since you don't know me, but whatever :D
Summary: For an HPDE and a novice driver they were predictable and equated to having more grip than I knew what to do with on a wet surface. They hydroplaned earlier than I'd like, but if you're dealing with standing water at a track day you should be taking it easy anyway (imho). On the freeway you might end up in the slow lane compared to those with solid all season tires. Around town they hold very well.
There you go, that's my amateur review of this tires wet performance.
- It was my first time on Pacific, I did not push things.
- According to a few weather stations in the immediate area, 1.5 inches of rain fell that day. I can attest that most of that fell during the event.
- Cold Tire Pressure: 32 rear, 35 front.
