The Pirrelli range is is huge and makes it confusing. Rosso Corsa 2 is a good summer road tire but needs mid range heat , the SP would be a good intermediate rider option for the track, probably dont even need tire warmers. If you are using warmers, on those crossover ties , run the warmers on the lower setting or 40-70 degrees C . When these tires start to fail ,is when they are pushed hard and get into the higher heat range . Going up into the SC slick and treaded , they need to be hot off warmers and ridden hard to keep the heat. The catch is they are so hard to manage , every day different conditions , start of the day through to the warmer afternoons with fully heated rims etc. Just 1/2 PSI out and you can destroy a good tire in a few sessions . With the mid range tires they aren't going to catch you out as in just let go and your down , they will chatter and develop gradual slides with plenty of warnings . The track only range, if they fall below their heat range they can give you no warning at all , often in front end looses .
Trying to explain , even with road tires temperature is the gauge, pressure is the tool to get temperature. And its not that simple either.
