Can I use Slime Tube Sealant in a tubeless tyre?
No. This red label Tube Sealant formula does not contain the rust and corrosion inhibitors necessary to protect a tubeless wheel. We do not recommend or guarantee performance of the product in this application. But Slime does offer a 2-in-1 Tyre & Tube Sealant (black label) that will work in a tubeless tyre, or a tyre with a tube. Same great Slime two year protection, with more flexibility!
