Friends don't buy used tires from friends.
Serious question, though. Are you still friends with this guy?
The track community is generally tight-knit and a good community where people look after one another. Emphasis on generally.
I'm curious how many days the CRS were used to the point of being heat cycled out? I read on various forums that the RE71Rs wear really fast, but unsure of heat cycling. For my next tire, I am on the fence of continuing with an endurance tire such as the Hankook Ventus RS-4. While they are great, they last too long (FWP) and it doesn't give me the opportunity to try other tires to experiment a bit more. (Insert world's smallest violin.)
