Tire Bead Lube. Delta First Bead Lube Concentrate is probably the slipperiest in the industry! The turquoise colored concentrate can be mixed 3 to 1 with tap water to make an efficient and economical mounting lube. It’s much slicker than mounting paste and allows tires to easily slide and get the bead properly mounted on the rim. Additionally and unlike competitive bead lubes, it contains a rust-inhibitor package that will not allow rust to form on the rim. It’s entirely non-toxic, odorless, and environmentally friendly. 4 per case.
