The 1oz bag is packaged 4 individual bags in a bag.
To achieve maximum results, it is important to use the proper package size for each tire. As a rule of thumb, the amount of Counteract required per tire is based on one ounce per thirteen pounds of tire. 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 bead seating area of the tire and rim. Counteract 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 a Counteract valve core and a metal CBB valve cap is recommended and included in every bag of Counteract. Counteract is TPMS compatible.
