And once you drive on a deflated RFT, it is toast - it must be replaced (and the 20" rear Dunlops cost +/- $650 per tire).
If your RFT goes flat on the Beltway, you may be able to get home okay. But if you are on a family vacation to the Outer Banks you are SOL. And what do you think the odds are of finding a 20" RFT on a Sunday in OBX? In that scenario, you'd be far better served by the Conti's.
IMHO the ONLY reason a RFT might be better than a non-RFT would be in the event of a catastrophic blow out, where the RFT would give you marginally better maneuverability. (But having driven on a blown-out RFT, I can tell you it is anything but confidence inspiring. Consider that most blow outs happen because of underinflation, and that you have to be a world class knucklehead to ignore the TPMS, and I think the whole RFT deal is a load of hogwash, invented to allow manufactureres to bypass the expense and space considerations of providing a spare.
My 2 cents. YMMV.
true that- well said! getting a flat isn't exactly an "average" experience...I've been served by the coorperation.....
