Independent testing has shown huge savings from this very small investment.

• It's self-calibrating. When the cap is first mounted on the valve stem, it will “memorize” your tire pressure. The cap will then be calibrated for life and will not require resetting.

• The car version will fit any car, light truck, or SUV on the market (pressure range 10-70 psi, or 0.7-5.0bar) and the truck version will fit any truck, RV, camper or other heavy vehicle (pressure range 60-170psi or 4.0-11.0bar).

• Since two versions cover any tire pressure between 10-170psi (0.7-11.0bar), there is no need for dealers to carry large stocks of different caps.

•  The valve cap can be calibrated to any tyre pressure between 10 & 150psi. No need to carry large stocks of different caps.
