To achieve maximum results, it is important to use the proper package size for each tire. As a rule of thumb, the amount of ECO Balance Beads required per tire is based one ounce per thirteen pounds of tire and rim combination. If you are not using an applicator and pouring the contents of the bag directly into the tire it is imperative that none of the contents of the bag ends up on the tire bead seating area of the tire and rim. If you are using our throw in bags, open & discard outside bag only & throw clear inner bag containing ECO directly inside tire cavity. ECO Balance disclaims any responsibility for air loss or tire damage due to improper installation or air check. In order to reduce the possibility of valve leaks, the use of the provided valve core and metal valve cap is recommended.
