I've been running the 215/40-17 RSR for about 1.5 years now, no complaints about road noise. It's slightly louder than the stock tires (which to me are pretty much silent) but especially with an exhaust I can't hear these tires at all. My buddy has a very different experience on his E92 with the RSR and the noise is more noticeable.
The RSR was great on track and didn't overheat on me like the stock tires did. For the price as a Summer tire I'd definitely buy it again, especially because in comes in FIST friendly sizing (17")
In the Fall of 2015 I dropped my car off at the dealership to address a transmission issue, unfortunately due to back order of parts this ended up taking > 2.5 months and I picked up my car about a week before Christmas (with the RSR's still on)
DO NOT leave these tires on in Winter conditions (unless you live in a pretty warm area of course), I'm in Vancouver and it only drops to about 0 degrees Celsius (32F) but they were still enough to crack these tires
All 4 tires now look like this and I'm not comfortable tracking on them any more
Trying the RE-71R which should be here next week. Online Tires is backordered on these (same situation in 2014 actually) and last time it took > 2 months but I didn't mind the wait since I didn't have my wheels yet
