That is true, but it is not really an "advantage". Because RFT are so bad, the shocks have to overwork.

If that was the case, non-RFT super summer performance xtreme add your superlative Michelin Pilot tires would be as stiff as RFT. They are not.
All I know, is that I preferred the handling of the non-RFT tires by several parsec. It does feel a bit soft on the stock shocks, but it has very predictable limits, RFT tend to loose it more abruptly, I don't like that.
