[CREATIVE]: This kit allows you to air down tires quickly without waiting or constantly monitoring tire pressure. The deflator valve will automatically stop at your pre-set PSI value. [ACCURACY]: Each tire deflator is individually calibrated, with +/- 2 PSI considered acceptable. The deflator kit is designed for quick off-road air-down setup, not for precise vehicle tuning. [ADJUSTABLE]: No tools are required. The tire deflator features a clear scale display. Adjust to the desired air pressure, and it stops releasing air when the set PSI is reached by twisting the deflator shell (where the logo is located). Adjustable range from 30 PSI to 10 PSI. [PACKAGING]: This kit includes 4 deflator valves. It is an ideal tire deflation tool for off-road use, trucks, powersports, SUVs, RVs, or UTVs.
