Why would this be any different than a non RFT?

Beyond that, the cars actually are designed and suspensions tuned with the stiffer sidewalls of a RFT. This doesn't mean it's tuned to our liking, as bean counters are involved, but they are. Either way, I replace with non RFTs and I order them online so I don't deal with SAs trying to tell me what I need to buy.
