Are you using the RSRR or RSR? Tread pattern is different between them. That's how you tell. R888 has a treadwear of 80 compared to the 140 of the RSRR it should have more grip. One is a proper semi-slick the other is a UHP road tyre. AR-1 should perform closer to the r888 than RSRR.
So what was your results ? And Federal RSR are pretty average tbh.
new model?
We were testing 2016 model. For 2017 Nankang will upgrade composition for more performance. It will be our control tyre for 2017 season.
nice! this is a track only tyre?
Street legal as well
How can I recognize which model I have? I've made the first test today but I am confused. The grip of Toyo R888 seems to be better.
