Hello,
didn't had it on the car. Found a german summer tyre test:
http://www.reifen-goeggel.de/fileadmin/user_upload/reifentests/Aubi12_09_074-081_Reifentest_1_.pdf
Tyre wasn't in the Top 10, so they didn't test in detail. Tyre was tested in the dimension 225/45/R17 on a BMW 3 series. Achilles ATR was on place 29 of 50 tested tyres.
Best stopping distance on dry ground was 35,2 metres. Achilles ATR was 38,1 metres.
Best stopping distance on wet ground was 44 metres. Achilles ATR was 50,7 metres.
In general it seems to be a low budget tyre which is not that bad. Also seems that the tyres seems to be a lot smaller than the nominal wide – which can be problematic with parking and kerbstones.
Regards, Markus
