The best tire puncture sealants can be a great convenience in an emergency situation, when used properly. Tire puncture sealants have drawbacks so it is important to know what you are doing when you use them.
Pros of Tire Puncture Sealant
Aerosol tire puncture sealant is easy to apply. You do not have to remove the tire from the rim, or even from your vehicle. As you spray, it forms a viscous gel that will coat the inside of the tire and plug all leaks or punctures. Start driving your vehicle within a few minutes of inserting the sealant, so the tire's heat can spread the gel evenly around the inside. Tire sealant also costs less than parts and labor for patch repair.
Cons of Tire Puncture Sealant
Improperly applied, tire puncture sealant can ruin your tire. If the tire with the sealant does not move and warm up quickly, the sealant will pool in a lump at the lowest point of the tire, causing the wheel to be off balance. This can lead to an accident and possible injuries. Many service centers will not repair a tire treated with a spray sealant, meaning you will have to replace the tire anyway.
