Your Thoughts on Mandating 200+TW "Street Tires" in Improved Touring?

Here is one issue that I'm not happy about and it could skew people's data with regards to street tires. If you run street tires on a track with a lot of race tire rubber laid down the track will feel "greasy". The race tire rubber and street tire rubber don't work well together. Basically the street tires will perform better on a green track than one with a lot of race tire laps on it.

That's a pretty big concern given that every other class running a race weekend will be on at least r-conp if not full slicks.

Happens at the drag strip as well. "Street tires" or drag radials will pull the rubber up from the starting line leaving bald spots. Had a nice chat (and beers!) with Bill Bader Jr at Norwalk, now Summit Raceway during a Sport Compact event. YEARS ago. Not sure if the newer drag radial compounds, like the street tires SCCA racers now use, play along better. Need a cool Friday night to go check them out
