 Heat cycling always help the tire last longer but not sure

 that race slicks have several compounds from soft to hard
 just wondering about the A6's??
 
 Ron or anyone had any experience with them

WE are trying the A6 because of the tire temp measurements of the R6's when running Thunderhill. 
We ARE not racing.... and I'm certainly no race car driver.... a real race car driver would most certainly generate too much heat... but I don't. I also have a complete set of R6's mounted on another set of wheels -- so if the temps tells us the A6 is getting too hot... a simple switch will be made. WE are doing this based on the science of our own measurements, rather than, what someone told someone else's buddy one time. 
The tire pressures I WAS using were near but not close enough... actual measurements of the tire temps and ending pressures etc gave us the info needed to set the tires right. Now - that's the new numbers being used instead of just kinda sorta someone else is using X pressure.
