Grib;
Thanks for that first-hand info-- very interesting.
I suspect those Daytona/Talladega tires you grooved were fairly hard
compounds as the speeds and loads on those high speed banked tracks are
pretty tough on tires. Rain tires are much softer and stickier-- something
like "qualifying" tires. The groove pattern on rain tires has been developed
to literally "pump" the water out of the tire's contact patch with the road,
so hand- grooving isn't quite the same.
All in all, this "wide-tire question" doesn't have a cut & dried answer. I
think the previous string on wide tire camber sensitivity also comes into
play, too. Some cars can benefit from wide, stickey tires, others handle
poorly with them.

Subject: RE: Parachutes & wide tires
I went to the Salt last year and tested different tires. My best results
were with the 12" wide "Rain Tires" that NASCAR used at Japan. I spun
twice testing the Daytona/Talladega tires I grooved and once cause I
couldn't take my finger off the NOS button.
Mayf could probably give us an equation as to what fluid (air being a
fluid) handling characteristics that particular tire has. Me I'm just a
converted redneck and I know what worked for me. Wishing I had a dollar
for every time I did something someone told me I couldn't.
I'll use skinny tires on the front of the Merk but I'll try to fit those
rain tires in the back.
Best to all,
Grib
