(225/45 R17) on
When I ran the Hankook RS4's, they were an expensive compromise tire for summer and HPDE events. You sacrifice some cost for excellent (but not the best grip) and the best wear in the class. I swapped to set of wheels/tires with RE71R's for Competitive AutoX. I wanted track tires that can last 2 seasons of HPDE or around 7 trackdays a season to save money while I learn and hone my skills. For Lucky Dog endurance racing in the States, this is the tire used because they wear like iron. I got 3 seasons of HPDE, and summer driving on them until they aged out and I gave them to a friend who still uses them on his ****box E36 318i. Because of how long they heat up, they are not the tire for AutoX unless it's a long course that is more than a minute and a half. When I took it out, even on a 80 degree day, it took 3 session to get to temp, and was sliding around until then. It takes 2 laps to get them to temp on a circuit. The grip is 80% of what RE71R's can be so you won't be getting the max potential out that you car without a faster (more wearing) tire, but they last once their heated up. You can turn lap after lap consistently, with little greasing which can be rectified with a cool down lap. They like heat and high pressures (compared to Falked RT660/ discontinued RE71R). Also a smaller width tire is better than a wider one if you want to enjoys nice progressive slip and lateral grip going in and out of corners. As with any 200tw tire, noise and comfort are tertiary. But they are a fun tire to drive on when you know its going to be dry and you want to canyon carve at 10/10ths. I would avoid rain at all costs in this car. On the track they are okay, but on the street if you run into any body of water you're going sideways. Compared to 200tw tires from Falken, Dunlop, and Yokohama, RS4 tires are the worst in the rain.
