Im not here to bitch about the RR tire, because it is hands down a better tire. From my experience with them, which has been only a few races, i love them. I have run laps with track temps in the 40’s and just this past weekend with track temps in the 90’s as well as in a 12 hour enduro. People have to realize that it is a different tire, where setup and driving style has to change. Without the change you cannot compare to the RA1. I have over 5 heat cycles on a set with great wear and speed still in them.
If you have a problem with the RRs, buy a set from Phil. I heard he puts special air into every tire, good for a few more tenths.
