Fix-A-Flat 12 oz Aerosol Tire Sealant & Inflator for Compact Tires
Product description
What it is: a single 12 oz aerosol can of emergency tire sealant and inflator intended for compact tires. The product is supplied as one pressurized canister with a valve connection so you can attach it to a flat tire and dispense the sealant while adding air.
How it works: the formula is engineered to seal small punctures in the tread — historically rated for holes up to roughly 1/4 inch in diameter — and to provide enough inflation to lift the wheel off the ground so you can drive on to a service location. The manufacturer states the formula now seals holes about a third larger than previous versions and that the product has been in use for decades.
Safety and compatibility: the sealant is presented as TPMS-safe and described as having an eco-friendlier composition intended to be safer for the user, the tire, and the environment than earlier formulas. No jack, hand tools, or spare tire are needed to use the can.
Use and follow-up: the procedure is to connect the applicator to the valve, dispense the product to both seal and inflate, and then drive carefully to a repair facility. Store the can in your vehicle’s trunk for emergencies. Professional servicing of the tire is recommended soon after use — typically within a few days or after driving a modest distance — so the tire can be properly inspected and repaired or replaced as needed.
Pros
- Quick temporary seal and inflation
- Works with tire pressure monitoring systems
- Compact and easy to store in trunk
Cons
- Not suitable for sidewall or major damage
- Can make professional repairs more difficult
- Limited shelf life and temporary solution only
VerdictThis 12 oz aerosol offers a fast roadside option for small tread punctures — connect, dispense, and drive to a shop. It’s convenient, TPMS-safe, and useful when you don’t want to change a tire roadside. However, it’s only a temporary repair: it won’t fix sidewall or major rim damage and can complicate professional repairs if left inside long-term. Treat it as a contingency product to get you to a

Held air and was easy to clean
Used two cans after a torn valve stem and drove about 30 miles; tire still held air two days later. Cleanup was simple with a hose. Note: tell technicians you used a sealant and follow can directions for best results.

Caused trouble at the shop
Kept a can in the trunk, used it after a flat. It was hard to dispense and the mechanic warned it can corrode rims and ruin the tire, preventing proper repair.

Saved a ride home on a motorcycle
Used one can when a Harley rear tire deflated. It sealed to the rim and valve enough to ride home even though the inner tube was ruined.

Restored mower tires for months
Applied it to my John Deere front tires that had been losing pressure. Easy to use and still holding air several months later.

Sat for years, then sealed a nail
Left it in my truck for three years; a nail got me an hour from help. The can inflated and sealed the tire and I drove two hours home towing a boat with no loss.

Didn’t work for my tire
I carefully followed the instructions but it failed to seal my damaged tire. Would have liked a zero-star option.

Fixes flats when needed
A bit expensive but it does the job when you need a quick temporary seal.

Handy in an emergency, know the limits
Shelf life is short and it only helps with tread punctures, not sidewall or rim damage. Good for getting to a garage, not a permanent repair.

Works on slow leaks
Effective for slow or small leaks; good to have on hand for unexpected punctures.
