It's more expensive to run RFTs than conventional (though, you do have to purchase a spare tire, wheel, and jack kit)... RFTs are more expensive and given that repair is becoming more and more rare, you'll be coughing up for a new tire at almost every flat. Plus, depending on your mileage of the other tires, you could be in for two/four new tires even if they have miles left on them.

And there is no doubt that the RFTs are still kind of a rare bird. You don't want mix and match manufacturers or tread wear. I couldn't find anyone (EVEN GY) who could supply the tires that my 2012 M came with. I had to get it from the dealer.

I'll be looking at the issue again when it's time to replace the tires. At that point, I may opt for conventional tires with a spare.... Not really sure.
