Hoosier makes a (Quicktime DOT) tire with the same soft compound as their Quicktime slicks but with thicker side wall and regular street tread.
Yes, I have run these tires in the past. Good tire, but squirrelly as hell in the rain. I have driven them in the rain in the past, when I was younger, but then I did a LOT of things when I was younger that I wouldn't do now.
A good friend has a T bucket with a healthy BBC and very wide M/T tires, it is a very scary ride on dry pavement. I can't imagine a damp day....
I run my Hurst on the street all the time for over 2 years now rain the car stays home, but I've been caught in a few storms and been cautious with no problems just can't be jabbering on a cell phone and act like you're driving a civic JUST BE SMART YOU'LL BE FINE!
A friend of mine had the same setup. He was coming home from a rodrun on the beltway. He came around a bend right after one of those black clouds had just passed through. He did a complete 360 across 3 lanes. Luckily traffic was light and he did not hit anything or anyone. A nice bright warm summer day. No warning and no real rain.
Tires are very much an engineered safety related item. Everyone knows the facts about slicks on the street. They are what they are. The act of siping or grooving tires that were never intended to be modified is just plain foolish... especially with a skill saw!
