They don't like cold (less than 50 degrees) temperatures. You have to get a few laps into them before asking for 100% on cold days. They can break away quickly on cold days. Not the most forgiving tire, but well worth the compromises.
Yes, they are tolerable on the street in the rain. I was specifically wondering about their potential as a rain backup to the BFGs at the track, but what you are saying confirms my concerns. So, if it rains, I'll simply not go out until I go back to PS2s on the stock rims. Thanks.
