TireJect™ Technology
TireJect's patent pending tire sealant formula contains natural liquid rubber, recycled rubber tire particles, and aramid fibers (see material contents). The active sealing particles and fibers plug punctures and leaks from the inside while the liquid rubber bonds to the tire to form a permanent seal.
Compatible with all off-road tubeless tires:
ATV, UTV, Side by Side (SxS), golf cart, utility trailer, lawn mower, tractors, farm equipment, construction and heavy equipment, etc.
Puncture demos
Make your tire, literally, bulletproof
Do not attempt this at home! TireJect is the most effective tire sealant on the market - we have made all sorts of puncture demo videos, but this shows it all! Seal any leaks, punctures and even bullet holes!
Driving over a bed of nails
If you see us at a riding event, we are still riding on this tire. We 100% trust our tire sealant and it permanently seals any air leaks from punctures up to 3/8" in the tread or sidewall and even seals bead leaks or dry rot.
TireJect™ vs Slime tire sealant
Anyone that has used a traditional tire sealant like Slime tire sealant knows that it is an absolute mess to work with and commonly does not work. Slime is thick, goopy and designed to stick to your tire and rim. The thick formulation of Slime is designed to stick to the tread area for limited protection of your tires and it causes tire balance issues.

4 onces is all it took to fix a slow leak on my Chevy Trax. I would recommend TireJect to anyone who has a leaky tire. I would call first to make sure it is compatible with your tires pressure sensor. Thank you TireJect.
