They are a great value compared to the Hohos and have a DOT stamp too if they are needed to drive to and from the track.

The key is the definition of longevity.
For most hpde drivers the definition is ... Good until you can see the cords. Grip was long gone.
For racers and serious drivers, tires are done when the lap times have dropped more than a couple of tenths of a second. For race tires, that is about ten heat cycles.
Race tires don't just lose grip after 10 heat cycles
. They change the way the car handles because of it. That is why you don't do any suspension tuning on old tires.
RR's were 2sec off the other tires out of the box. Started losing time after first heat cycle. By 10 cycles, they were another full second of the pace
Data was gathered from three drivers in two similarly prepped SCCA race cars.
.
If someone just had to have real r-comps to win the hpde, at least get Hankook z214's. Better and I think cheaper than RR's.
Have I mentioned that RR's really suck? 😎
