Had two sets of these tires and both sets didn't even last 12K miles until the wear-bars began to show and I needed to replace them! The first set was a prorated replacement and I figured the premature wear was a fluke...plus the price was right. But after the second set wore the exact same way, the dealer couldn't pay me to put another set on! Worse tires ever!
Dry road performance was good when new, but never great. Wet road performance was always an issue, and only worsened with tred wear.
Just replaced all 4 tires on my C230 Sport with Falken ZE912's and they are fantastic so-far both wet & dry! I live in Florida and they came highly recommended for our heat & rain conditions. Minimal high speed road noise and great handling & cornering! Too early to comment on tredlife, but they can't be any worse than the set of Hankook Ventus V12's they replaced that didn't even last 12K miles till the wear bars began showing on all tires! And these Falkens were half their price!
