Great tire for track and auto crossing. Dry performance and treadwear is pretty good.
The AD08R is an excellent all-around extreme performance summer tire.Tyres are great at braking and turn in is much better compared to conventional tyres.
The tires perform excellent in dry handling, and even performed quite well at two autocross events. The extra-stiff sidewalls add instant turn response and hold the car during sharp cornering.
The RT615k+ feels great after the initial layer of compound and release had worn off the traction on and off the course has been great. On the track they get to temp quick and keep at the optimum temps with little to no overtemps.
Very predictable grip, lots of feedback, and they will take the constant heat and abuse of endurance racing.
This tire is solid all the way around in dry weather. Strong sidewall feel in corners .
These tires do not break traction at all under dry condition, they are extremely sticky. Wet condition is also very impressive.
These are a terrible autocross tire though. They need very high temps to work, and unless you've got wicked ambient heat at the autocross, you just aren't going to get any traction out of these.
