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.
Cost of flat-tire repair
Passenger-car and light-truck tires inspected for repairability. Roadside spare installation is a different service.
| Service or charge | Planning estimate | What it covers |
|---|---|---|
| Repairable tread puncture | $25–$50per repairable tire | An internal repair of an eligible tread puncture, with tire removal, inspection and rebalancing.Ask whether the tire is repairable and whether the quote includes the internal repair and rebalance. Sidewall damage requires a different decision.Scope detailsIncluded in this estimate: Removing and inspecting the tire; Approved internal puncture repair; Remounting and balancing Separate unless quoted otherwise: New tire; Roadside dispatch; Unrepairable damage |
| Rubber valve-stem leak repair | $15–$30per tire | Replace one ordinary rubber tire valve stem and restore the air seal; not an electronic TPMS sensor.Confirm whether tire handling and balancing are included. A TPMS sensor is a different part and price.Scope detailsIncluded in this estimate: One ordinary rubber valve stem; Replacement labor Separate unless quoted otherwise: Electronic TPMS sensor; Separate tire-handling charge if not included |
| Bead-area leak service | $20–$50per tire | Remove an ordinary tire, clean and reseal a minor bead-area leak when the tire and wheel remain serviceable.Ask whether corrosion cleanup, remounting and balancing are included, and whether wheel damage prevents a lasting seal.Scope detailsIncluded in this estimate: Tire handling; Surface cleaning; Reseat and leak check Separate unless quoted otherwise: Structural wheel repair; New tire |
| Replacement if the tire cannot be repaired | $100–$135per installed tire | Budget example for one new ordinary 215/55R17 all-season passenger-car tire, with standard mounting and balancing.Match the full size, load and speed rating. Ask whether tread matching or the vehicle manufacturer requires replacing more than one tire.Scope detailsIncluded in this estimate: One example 215/55R17 all-season tire; Standard mounting and balancing Separate unless quoted otherwise: Tax; Shipping if charged; Disposal and TPMS parts; Road-hazard plan; Alignment |
What affects the price
- Puncture position, internal damage, and prior repairs determine repairability.
- Run-flat construction and manufacturer instructions may limit repair options.
- An existing tire-service package may already cover eligible puncture repairs.
Questions to ask before booking
- Will you remove the tire and inspect the inside before deciding?
- Does the repair total include refitting, balancing, and all required fees?
- If replacement is needed, does my existing coverage or warranty reduce the bill?
Before you book
Shoulder or sidewall damage is not a routine tread-puncture repair; ask for the inspection finding before comparing prices.

Frequently asked questions
Which punctures can be repaired and which cannot?
Tread punctures in the central band, from something small and straight like a nail or a screw, are repairable. The sidewall is not, ever, and neither is the shoulder where the tread curves over, because both flex too much to hold a patch. A cut, a gash or a tire that was driven flat is finished regardless of where the hole is. Two repairs close together usually mean a new tire.
Plug, patch, or both?
Both, in one piece, is the repair you want. The plug fills the hole through the rubber so water cannot creep in and rust the belts; the patch seals the inner liner so air stays put. Doing it properly means taking the tire off the wheel, which is also the only way anyone can inspect the inside. A plug alone, fitted from outside, gets you home. Treat it as temporary.
Does sealant in a can cause problems?
It gets you moving and it makes a mess. The foam coats the inside of the tire, so the shop has to clean it out before anyone can find the hole or stick a patch to it. Some formulas gum up the pressure sensor inside the wheel and some sensors do not recover. Tell the shop you used it, up front. A few refuse sealant-filled tires entirely.
My car has no spare. What now?
You have three options and one of them is bad. The sealant kit in the trunk handles a small tread puncture and nothing else. A tow or roadside call gets the car to a shop with the wheel intact. Limping to the shop on a flat is the bad one, because it turns a repair into a purchase. If the tire holds air with a compressor, drive gently and stop the moment it goes soft again.
Can a run-flat be repaired?
Sometimes, and the answer comes from the maker of the tire rather than from the shop. Run-flat sidewalls are built to carry the car with no air, so once they have done that the structure may be cooked even when the rubber looks fine. The shop needs to know how far you drove and how fast. Some brands permit one tread repair; others rule it out completely.
