Not happy with the X5, is it the RFT?

[Alan Smithee]

Can't help you, fellas. All I am doing is pointing out that a RFT can be repaired if otherwise undamaged, just like a non-RFT. The most highly respected tire store in this area patched one for me, no questions asked, but the tire did not lose air. Bridgestone backs that up. Dunlop's website doesn't say they can't be. Those are the only two I looked up. I am not aware that other OEM X5 run-flats use a different design, so they should be repairable as well. The legal exposure is whether the tech doing the job is competent enough to look for signs of deterioration; apparently some manufacturers and shops are willing to take that risk, and others are not. Again, same as a non-RFT.

In my experience, big chains like Discount Tire will not repair a non-RFT either. It has always been a cash transaction directly with the tech and no paperwork.
