Most places won't repair a RFT IF it has been driven after going flat. But, if you can keep enough air in it (slow leak), it is repairable like any other tire.
The issue is, it isn't always obvious there's any internal damage, so most manufacturers and reliable shops won't repair one. Sometimes, if driven further than recommended at higher speeds, when dismounting it, there's a handful or more of rubber chunks. Then, it's obvious, but not always. |

I finally got it repaired here in Canada cost me $50. The screw was almost in center inside the tread. Lucky! No issue so far.

If you don't actually drive it to zero pressure (say it's a slow leak and you keep filling it up), functionally, it's no different than a 'normal' tire. The problem is, there's no way to tell if you actually have driven it with zero pressure, and any internal damage MIGHT not show, so the tire could be dangerous. Most shops don't want the liability.
Some of the Michelin (and maybe others) are ROF, rather than RFT. A subtle difference. A RFT tire is supposed to be be able to handle full load for 50-miles (as long as you don't exceed the speed limit). A ROF tire's ability to run flat will depend on the load, and only a lightly loaded vehicle can go 50-miles. A ROF tire tends to ride better as the sidewalls don't need to be quite as robust. |

Interesting. However I don't really buy the claim of jack capacity difficulty. Heaviest Model X is 5,500lbs and our cars are in the 5,000lbs +/- a few depending on model and configuration. There are also plenty of large SUVs and certainly pickups that are much heavier than that. So while a small jack from an '83 Civic won't handle it, there are plenty of jacks that will.
