Why do people bother with runflats??
They're very expensive, rubbish compared to the usual rubber.
I've never had a puncture on the road in 30 years of driving but in case you do, just buy a £5 repair and go can or carry a space saver replacement that you'll 99% likely never use!
I think it's more a case of horses for courses, not one size fits all. Yes they're generally more expensive, but some non-RFT tyres are pretty similar in price.
Rubbish? That's a bit harsh, it depends on what a person is asking of their tyres and their car:
If extreme grip and ultimate feedback - then you won't be that satisfied with RFTs.
If decent, overall performance - then quite possibly satisfied, especially if a higher aspect fitted to a smaller rim (eg 225/50x16 rather than 225/40x18).
If reassurance that the good lady isn't going to get stranded at midnight with a flat in a dodgy part of town - then certainly satisfied.
(And anyone who hasn't had a puncture in 30 years of driving is most fortunate indeed.)
Don't get me wrong, I'm not endorsing RFTs and I do think there is better rubber to choose from; but I am a little amazed at the way so many people jump on the 'ditch them at all costs' bandwagon without considering a person's individual requirements.
I've replaced RFTs with standard rubber on the E85, but my wife's last two cars have specifically had RFTs fitted and I've never encountered a problem when driving her cars enthusiastically

, though I do think the zed is more sensitive to its tyres than a Mini, and more likely to suffer tramlining. From experience, more so with RFTs on 18" rims compared to 16".

Right then, I'm off to find out what my wife is doing visiting a flat on the dodgy side of town at midnight... :x
