No experience with here with an E70, RFT or reg, but what would
be your concern? Seperate wheels, new tires, mount 'em up and
run them. I own a car that came with RFTs and now have non-RFT
tires on it: it's day and night...smoother, less noise, etc. Turn in
is not as good, surprisingly, but grip is superb. Not apples to apples
as I'm referring to my Vette not an X5.
My opin reads just like yours above...
"high speed blow out"?
What does that have to do with RFT tires or non-RFT tires? If you
suffer a true high speed blow out, (about the same odds as winning
your state's Daily pick 3 lotto, imo), a run flat tire is going to provide
about 1% "cushion" vs a reg. tire. A blow out is a blow out and they
happen very infrequently esp. on cars that toddle along at 80 mph
and less.
Slap on your set of snows and enjoy them. Be prepared for a possible
flat however.
