Discount tire repair in a can.

Flat tires are no match in a pinch.

Is that aerosol can a true emergency flat tire repair tool or would it be better used to flag down a trucker via his windshield? Remember, if an auto repair product seems too good to be true, it probably is. Now forget you ever heard that for a minute. Fix-a-Flat is the real deal, and it's the original roadside flat tire helper. It really does temporarily repair tires, like a discount tire fix in a bright yellow can.

Fix-a-Flat really works. It's safe to store in your car and can survive blistering heat and freezing temperatures.

All you need to know now is how to use the thing. What are you waiting for?

How to Use Fix-a-Flat on a Flat Tire

Warning: There is some evidence that aerosol tire sealers can harm TPMS (Tire Pressure Management Systems). If your car is equipped with tire pressure warnings, please consult the manufacturer before you add a can to your roadside emergency kit.

Fix-a-Flat is almost entirely self explanatory. It can repair tires. But like all things simple, it's the little things that can clog up the works.

Get ready to save the day:

  • Pull over to a safe area.
  • Remove the black cap from the valve stem (the nipple that the air comes in through).
  • Put the cap in a safe place, you'll need to put it back on when you're done.*
  • Screw the can of Fix-a-Flat onto the valve stem, you'll hear it start to fill the tire with air.
  • When it stops filling, unscew the can and replace the valve stem cap.
  • Drive the car right away. The sealant in the magic can needs to circulate evenly inside the tire to fill the leaky hole and ride evenly.
  • Plug the hole yourself or take it to the shop.

IMPORTANT: Remember that Fix-a-Flat is designed to get you to a safe place only and should never be considered a permanent tire repair. Fix the hole properly as soon as possible.

If you have your tire repaired at a shop, be sure to tell them you used Fix-a-Flat. They need to know that your tire is filled with aerosol gases and not just air.

*Your valve stem caps keep debris from clogging the valve, and keep water and ice from collecting. Both could cause problems in an emergency.

Warranty Issue, Member SCCWS

I used Fix a Flat and it worked great. But when I got the tire to Firestone, i was informed that any canned tire filler voids the warranty on the tire. I checked the warranty booklet and it did say it voided the warranty. I called Bridgstone/ Firestone corporate and got nowhere. According to the mechanic, the foaming material eats the rubber and ruins the tire. I called Fix-a Flat which was sold off by Pennzoil and was informed that certain tire warranties are voided w the product even though it causes no harm. Bottom line is that you might be able to repair the hole yourself but going back to a tire store will not work.
