Run flats will be a deal
Run flats will be a deal breaker for any future car I own period! If you are going to ruin the tire by driving on it after it it is deflated, why not buy a can of tire sealant for a few bucks, pump it into the punctured tire and drive to the tire shop to buy a much less expensive, better handling, more comfortable tire.
Run flat = $200.00 - $500.00 wasted if you drive on it with no air as intended.
Conventional tire = $100.00 - $300.00 and almost any tire shop will repair it unless the damage is in the sidewall.
