Hi Lance we tried to contact you over email to help with your installation. TireJect will always seal a tire and there are only a few reasons it would not work. We would first like to verify the type of vehicle, tire size and dosage installed. Inadequate dosage for the tire size is the most common reason a tire would fail to seal. The other reason might be a leaky valve stem or valve core. Please contact us at help@tireject.com and we can provide further assistance. I am sure we can find out what is going on and seal your tires.
