toyo R1R is very good too... RSR is Federal 595RSR from Tw... u can try to google it la...
My R1R not even 1k km on the road but already sand blast side skirt front part and rear bumper insert become thinner (paint on those area gone after before 400 km of use). If not using rubber or something to mount on that area (last time got ori mud flap but throw away when got my bodykit), I guess will bocor very soon. The sand blast noise show that the tire is very sticky but only apply to dry road. Wet road on 225/18, drive 80km/h and hit water is very dangerous. I got few minor skids not too long ago, end up with driving 60km/h for few hundred km .
