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.


First we recommend doing a soap and water test with a spray bottle or bucket and cloth. Spray or wipe the soapy water on the tire, bread 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 we recommend replacing with a Colby Emergency Repair Valve Stem as they are easy to install from outside the wheel without removing the tire.


Larger punctures
Start by adding half the initial dosage amount and re-inflate the tire, 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, re-inflate and remove the wheel from the vehicle. 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. Tires that are over 3ft in height could require 32 - 64oz of sealant - be sure to use our dosage calculator
