Changing an emergency flat tire just got easier thanks to Slime Thru-Core Emergency Tire Sealant. The emergency tire sealant seeks out and instantly seals tread area punctures up to 1/4 in. in diameter. There is no need to remove the valve core, Slime's Thru-Core Technology seamlessly injects the sealant through the valve stem directly into the tire. Then just air up your tire with an inflator to get back on the road quickly. This tire sealant is non-toxic, non-corrosive and tire sensor safe. This easy install formula cleans up easily with water.

For additional information on this product, please see the Product Documents section for all downloadable user manuals, installation guides, brochures and warranty statements.

Great to have on hand, just in case

21 days ago
The Slime flat tire sealant is one thing I like to keep on hand. We have a pick-up truck that has a slow leak in a tire, even after having it repaired. Keeping the slime with me for when it gets low gives me peace of mind to still use the truck until we can replace the tire.
