In a couple of months I would have been tracking the M3 for one year. So far I have been through Michelin Pilot Super Sports (PSS), Nitto NT05 (2 sets) and now Hankook RS3. In terms of grip and track use I would rate Michelin Pilot Super Sports #3, Nitto NT05 #2, and Hankook RS3 #1.
Now the NT05 and RS3 are both in the 200 treadwear category. I was planning to buy my 3rd set of NT05s but I wanted to change things up and see if I could tell a difference with tires of the same treadwear. From what I can tell, it’s a big difference. The RS3 is slightly more expensive then the NT05s but its was something worth trying out at least once.
With my brand new RS3 mounted, I recently had a track day to test them out. The levels of grip on the Hankook surpassed the grip of the NT05. Unfortunately my lap timer wasn’t working properly so I wasn’t able to get any data. Hopefully next month at MSR Cresson I’ll be able to acquire data. Subjectively, once heat cycled, the RS3 griped a lot better than the NT05. I felt more confidence to push the car harder after every lap. The tire warms up quickly usually after a couple of laps and the grip is just constant! I felt more g forces on the corners compared to the NT05. I didn’t have any sidewall scrubbing or overheated tries. The road noise of the RS3 is about the same as the NT05, I didn’t really notice a difference, but then again I do have a loud exhaust. Looks wise the RS3 isn’t aggressive looking as the NT05 but its something I can overlook. After tracking on the RS3s I don’t think I’ll ever go back to the NT05s. Don’t get me wrong though, the NT05 preforms well on the track. Its NOT a terrible tire at all, but if you are looking to upgrade to something better in the same tire category, then the RS3 would be a good tire choice.
