I am running on firestone firehawks tz100 215/60/16 and they have done about 80k and I am looking to buy a new set. Well aftermany phone calls to different Bridgestone Tyre outlets each unable to supply the firehawks I have purchased the Bridgestone Supercat which look great and feel good.CANNOT BE HAPPIER With myau2, this model has to be years ahead of its time.
