How Tire Sealant Works

Tire sealant coats the tire’s interior and is usually sold as a sticky, fiber-filled liquid. The sealant fibers are the ones creating the plug when the tire is punctured. Viscous sealant is carried out by the escaping air through the hole.

The puddled sealant flows into the hole if you drive with the punctured tire. The sealant plugs the hole as well. The sealant is pumped into the tire via valve stem opening.

You will need to use a jack to support the vehicle’s weight. The tire sealant comes with a manual where instructions are indicated so you can apply the sealant correctly.

See to it that you do not put in less than the recommended amount. The amount depends on the kind of vehicle, the size of the tires and how you use your vehicle (whether off road or on road).

Doing this can affect the sealant’s efficacy. This is because the tire does not have enough amount of sealant to cover or stop a puncture.

Check the balance and pressure of your tires before applying tire sealant. Your car can encounter imbalances when you move over uneven terrain or at higher speed.

How to Select a Tire Sealant

  • Corrosion Protection. Most tire sealants have water content, and water can take a toll on metal when contact is prolonged. Choose a tire sealant that contains corrosion inhibitors because replacing wheels due to corrosion costs hundreds.
  • Freeze Protection. Tire sealants that have protection from freezing temperatures should be considered so vibration can be prevented.

You will know you have purchased sealant with freeze protection if it is capable of providing protection from temperatures down to minus 20 or 30 degrees.

  • Fibers. Fibers are your tire sealant’s backbone. Choose sealants with stronger fibers as this indicates stronger tire repair. It also ensures faster and more permanent seal.
  • Fillers. The fillers should be capable of providing the final seal so airtight plug is ensured. Fillers are usually present in a high performance sealant.
  • Inertness. A sealant should not react chemically with any part of the wheel or tire. Avoid sealants that only work by reacting with air or curing.

Tips to Use Tire Sealant

  • You can only successfully seal a tire if you choose the right sealant. The final product you choose should be dependent on your vehicle’s tire size so be sure to take this into consideration.
  • Caution should be exercised at all times when applying tire sealant. Avoid smoking if you are sealing off the tire because tire sealants are made from flammable materials.

Before discharging the material in the sealant bottle, be sure to point the          bottle away from your face. Tire sealants contain chemicals that can be harmful when in contact with your skin.

  • The sealant bottle must be inserted in the hole. Read the instructions on the label and apply sealant as directed. When applying sealant, be sure that you are not experiencing leakage as it only means that the edge of the nozzle is not close enough to the tire surface.
  • The tire must be filled up with air once the sealant is applied in the tire. You can use the air pump to fill the tire up once the desired tire pressure is reached.

You should also take note of the recommended tire pressure and this is often indicated by your tire manufacturer. It can also be found on the manual.
