TireJect Tire Sealant will seal all air leaks from objects 3/8" or smaller. If a tire is not sealing its a matter of finding the problem area and making sure the sealant is able to come in contact with the leak.


Double check dosage

The most common problem we find is inadequate dosage for the tire size. Double check that you have installed the correct amount of Tire Sealant for your tire size.


First we recommend doing a soap and water test with a spray bottle. (CAUTION: Using to much soap and water spray can wash away fresh sealant and could cause further problems sealing the tire) Spray a small amount of soapy water on the tire holding the nozzle 8-12 inches from the tire. We also recommend checking the bead (seal between rim and tire) and valve stem to try and locate the leak. This works by causing the soap to make bubbles or a hissing noise at the source of the leak. If the valve stem is leaking you can first try replacing the valve core. Or the valve stem can be replaced with a Colby Emergency Repair Valve Stem as they are easy to install from outside the wheel without special tools or removing the tire.


Larger punctures
If you have already lost sealant while attempting to seal the tire start by adding half the initial dosage amount. Then make sure the tire is re-inflate to correct PSI and immediately rotate the tire so the puncture is at the lowest point. If you can hear the leak; rotate the leak to the bottom and pause to allow the sealant to pool right at the leak. Remember the tire sealant will pool up and collect to the lowest point of the tire, by doing this we are giving the tire sealant time to clot and seal the leak. If the tire sealant simply gushes out and does not seal the puncture this means it is to large and we recommend using a tire plug to fill in the gap. TireJect is 100% compatible with tire plugs and rubber cement and will seal around the plug for a leak free seal.



Sidewall punctures or mild dry rot

Start by adding half the initial dosage amount to ensure we have enough sealant in the tire. Remove the wheel from the vehicle and re-inflate to correct operating PSI. Then lay the tire down flat with the sidewall resting on the floor for 5 minutes and then flip over and do the same to the opposite side.

Visualize the liquid in the tire... the sealant will puddle at the lowest point and the objective is to ensure TireJect Tire Sealant is flowing to all areas of the tire in order to reach the leak and seal it. This process helps the sealant re-pool to the sidewalls and fully seal any leaks.


For larger tires that cannot be handled off the equipment (for example, a large tractor tire). Be sure you add enough sealant and refer to the dosage guide. Adding additional tire sealant will also help to make sure the sealant can reach the leak. Tires that are over 3ft in height could require 32 - 64oz of sealant - be sure to use our dosage calculator
