Overview: Flat Tire Repair
One corner of the car is down and you want this over with. Two questions decide the next hour. Can the tire be saved, and can you get to a shop without finishing it off. Driving on a flat, even a short way, usually ends the tire, because the sidewall folds over and grinds itself apart from the inside.
A proper repair happens from the inside. The shop pulls the tire off the wheel, looks at the inner liner for damage you cannot see from outside, and fits a patch and plug in one piece that seals the hole and fills the injury. A plug pushed in from the outside without taking the tire off is a roadside measure. Position decides the rest. A clean nail hole in the tread can be repaired. The sidewall and the shoulder cannot, and a shop that offers to patch either is telling you something about the shop.
Some cars complicate it. Run-flats are sometimes repairable and sometimes forbidden by the maker. Many new cars carry a can of sealant and a compressor instead of a spare, and that foam has to be cleaned out before anything can be patched.
Use the state and city lists below to find the closest shops. A flat is not a problem you solve by driving across town, so start with distance and call before you limp over.
