This post makes no sense! lol RT615's are like track day tires, they SUCK for daily driving and SUCK in the rain out of the box. I couldn't get 6 months out of them on my Miata and I ran quite a few sets but also tracked the car regularly. They defiantly don't hold up well though. Best tires I ever used were Toyo Proxes I forget which ones, they had decent grip and lasted over a year with track days, mountain runs every weekend, daily driving out the ass, etc.
