So ive been using this tires for(atr sport)........3 years, from 2013 till 2016. So what is my review regarding this tires. bought 215/45/r17(front) and also 225/45/r17 (rear). After a while the tires harden like your didi when your eyes see a sexy wimmin. Really bad grip during rain (brake test) and when it is dry i could do wheel spin with just WOT. terribly failed.
Then i change the front tire to my Gen2, use it for about a year and then one of the tire bloated, on the grooves not the sidewall. well thats bad.
Meanwhile for the rear tire i changed to Jinyu 245/45/r17, and no more wheel spin. The grip is much better, but the tires is really hard to find.
I hope theres a review for Rovelo Sport A1 and also Dayton DT30, Ive bought a set each but i dont know how to review a tire and its in my Gen2 where i drive it like a nanny, 3krpm is the limit.
Regards
