I still don't see the benefits of RFTs, I had a C-class merc as a loaner and it had a flat (on non-RFTs) and I honestly did not notice (and I'm surprised that I didn't because I had the thing up to 100+ riding essentially on the rim). Furthermore, the argument that RFTs are essential if you need to drive somewhere in an emergency is BS because you can drive on a rim, it's not a good idea but I have always been told never to stop on a freeway it's just not worth it unless you can pull off into a very safe area.
