Tested both ATR Sport & ATR Sport 2.
ATR Sport has very high threadwear count.
Very noisy but grip is level is acceptable.
Definitely better than T1R to me!
Managed to clock 40k km on it yet still thick as hell but experienced peeling for 195/55/15.
Changed back to S-Drive again. Loved it.
As for ATR Sport 2, had it on 215/45/17.
Still noisy but much quieter.
Uneven wear and tear eventhough having all 4 units new and balanced every 10k km.
Conclusion, "what you pay is what you get."
