I think the Michelin Latitude ZFT (run flat) all seasons are a great tire that can be patched, repaired, etc etc.
Just treat it like a conventional tire (ie dont drive it when flat) and you can use it precisely like a conventional tire (patch)
plus it gives you the added assurance of RFT if you or the wife ever needs it.
Michelin has recommended repair techniques (basically the same as conventional) but you simply cannot abuse the tire by driving 20 miles while flat and expect it to be repaired. People like to throw around a lot of hyperbole around rfts- as if it is a singular model of tire- but the truth is some mfgs. make a MUCH better RFT than others....
Keep it as simple as possible...but no simpler.
