How to Seal a Hole in a Tire Using Tire Science Sealant
Length of Clip: 4:18
This video will show you the easy way to repair punctures to your tire using the Tire Science Sealant. The sealant will repair a puncture up to 1/8 of an inch. Always be sure to wear protective eye wear when using this product.
WARNING: This sealant should not be used on tires that move at speeds higher than 45 mph/75 kph. Sealant may cause excessive vibration in tires at high speeds.
Step 1: Locate the Leak
Inspect the tire and locate the leak. Remove any object that has punctured the tire. If the tire still has some air pressure in it, spraying soapy water on the tire will help you find the location of the puncture. Be sure to mark this spot.
Note: A hole in the sidewall of the tire cannot be repaired using this product. Tire Science sealant-filled inner tubes will not seal sidewall punctures of leaks around the tire bead. It should also not be used with faulty valves or damaged rims.
Step 2: Remove Tube/Tool
Unscrew the bottle's cap to find the valve core removal tool and clear plastic tube tucked inside it.
Note: Using needle nose pliers will make it easier to extract the removal tool and tube.
Step 3: Prepare Sealant for Use
Remove the black cap form the sealant bottle cap. Cut the tip of the sealant bottle cap and remove the protective inner seal of the bottle using needle nose pliers. Screw cap back onto bottle. Then, place the clear tube onto the tip of the cap.
Step 4: Release Air Pressure
Remove the valve stem cap from the tire. If the tire still has air in it, use a small screwdriver to press in on the valve core to release all the air pressure from the tire. Use the valve core removal tool to remove the valve core and set it aside for later use.
Step 5: Determine How Much Sealant is Needed
Use the marks on the side of the bottle to measure the correct amount of sealant. The size of the tire will determine how much tire sealant you will use. Multiplying the height of the tire by the width of the tire, then dividing that number by 7.5 will give you the number of ounces to put in the tire.
Tire Height x Tire Width
Note: For better protection on extremely old or worn tires, use 10% more sealant.
Step 6: Squeeze Sealant into TirePlace the clear plastic tube over valve stem. Place the tip of the sealant bottle securely into the clear tube. Squeeze the correct amount of sealant into the tire.
Step 7: Remove Tube from Valve Stem
Remove the clear tube from the valve stem. Then, reinstall the valve core into the valve stem and tighten it with the removal tool by turning it clockwise.
Step 8: Inflate Tire
Inflate the tire to the recommended pressure. Place the cap back on the valve stem. Spin the tire or roll it back and forth on a table to distribute the sealant evenly around the inside of the tire. It is recommended that you mount the tire back onto your unit and spin the tire on the axle for best sealant distribution.
