This is The Ultimate Tire Gluer from D.I.R.T R/C Products. Make gluing tires incorrectly a thing of the past. With this unique tool you can gently pull the bead back and glue the bead then release the tool and get a perfect bead every time. It is for 1/8 Off Road Buggy Tires only. A must have for any racer. You'll wonder how you got along without it! Assembly and usage instructions are also in the bag. Don't forget to take the brown paper coating off of the jig before you glue it. ;)
