The car is very clearly quick and I can see how it overheats tires, particularly the RE71 and A7. Both tires have similar peak temps at ~140*. Mostly stock lower power cars, and newer drivers in faster cars can use them with success. Even skilled drivers in faster cars have also used with success. But throwing the entire line of tires out for everyone at the track is disingenuous at best.

Perhaps the SX2 has a much higher temp threshold, maybe more similar to an R7 at 180-200*? I bet it's a rock for a street tire.
140F or 140C?

RE71R are well over 220F after 1 hot lap if driven hard.

RE71R are a time attack special. If you're looking for similar grip, you can find other tires that have much more life than a RE71R, but don't carry the bs "200tw" rating. The only appropriate situation for the RE71R is when it is the only viable tire for competition within the class, e.g. a class that requires "200tw" tires. They are, in terms of both tire life and seat time quality, a terrible value.
