I drove 100+ miles home from Atlantic City NJ to Long Island NY on a blown Conti SSR. Forget that it took forever to get home. I had to make frequent stops to let the tire cool down. The sidewall on runflats is way too unforgiving and stiff when it comes to any variation in road terrain.
The tire itself wasnt too expensive for being an 18" runflat but it was a major inconvenience not having a spare.
Also, one has to imagine the added rotating mass and unsprung weight these tires add.
