The payment written into a loan is negligible. Perhaps a few bucks difference per month.
Actual Run Flat as seen on some high end cars takes special ($$) tires. I know of no aftermarket system that can give you more than a couple miles of low speed mobility which is seldom enough to get to a repair shop.
Why not prevent tire failure in the first place. Inspection and TPMS are the two steps needed.
