Run-flat tires can be driven 50 miles at 50 mph after a puncture. The trade-offs: 20-30% more expensive, harsher ride, shorter tread life, and harder to find. Most cars that came with them can switch to regular - here is when that makes sense.
Run-flats have reinforced sidewalls that support the car with zero pressure. Get to a tire shop or home without changing the tire roadside.
A set of run-flats runs $1200-$2000 vs $800-$1500 for comparable regular tires. Replacement frequency is similar.
Stiff sidewalls transmit more bumps. Many BMW and Mini owners who switch to regular tires call it the best upgrade they did.
Most run-flats wear out 15-20% faster than equivalent regular tires due to stiffer compound and lower-grip rubber.
Run-flat cars typically have no spare - saving 30-50 lbs and trunk space. If you switch to regular, get a spare or plan to call roadside.
| Factor | Verdict |

| Tread life | Regular lasts 15-20% longer |
| Roadside convenience | Run-flat wins big |
| Tire selection | Regular - many more options |
| Spare needed? | Run-flat: no. Regular: recommended |
| Repair after puncture | Usually replace run-flats, can patch regular |

Worth it if you frequently drive long distances alone, in remote areas, or hate the idea of changing a tire roadside. Not worth it if ride comfort and tire cost matter more, or you have AAA.
Typically 50 miles at up to 50 mph after total pressure loss. Some are rated 100 miles or higher. The vehicle TPMS alerts you immediately when pressure drops.
Almost always yes. Make sure to install a spare tire kit or carry a repair kit + compressor. Verify TPMS works (it does on all run-flat cars). Best to do all four at once.
Their sidewalls are reinforced with thick rubber to support the car with no air. That same stiffness transmits bumps directly to the cabin. Lower-profile run-flats are particularly harsh.
Yes, typically 20-30% more per tire than equivalent regular tires. The roadside convenience is what you pay for.
Most manufacturers say no - once a run-flat is driven flat, the sidewall structure is compromised and the tire must be replaced. Some tire shops will patch small tread punctures if driven on briefly.
