Yes, my Ventus K14s (or the predecessor to the current V12s) had a rim protector flange and the new ones do, as well.
IMHO the R-s3 is a very race-focused tire that is probably overkill for pure street use, and useful really only for dry pavement. I do like to have AT LEAST SOME capability for wet traction while still maintaining maximum dry/summer capabilities.
This has become even more important to me, surprisingly, after moving to Texas from rainy Portland, Oregon. This is because we get some SERIOUS gullywashers (rainstorms/thunderstorms) where you will have an inch or two of standing water on the pavement -- it's raining too fast to drain, as it will rain an inch every 15 minutes -- so having SOME water displacement capability is important to me. In the summertime you will get one or two of these a week -- although they last anywhere from 30 minutes to 2 hours.
I contrast this with the contstantly damp/wet/drizzly Portland, where there is very little standing water on the roads and few if any thunderstorms/gullywashers, perhaps one a year. But of course Portland is gray, wet or rainy 225+ days a year......
Cheers,
