Why Proper Tire Pressure Matters
Maintaining correct tire pressure is vital for several reasons:
- Maggiore sicurezza: Properly inflated tires offer better handling, braking, and overall vehicle stability, reducing the risk of accidents.
- Efficienza del carburante migliorata: Underinflated tires increase rolling resistance, leading to higher fuel consumption.
- Extended Tire Lifespan: Correct pressure ensures even tire wear, prolonging the life of your tires.
- Reduced Risk of Blowouts: Over or underinflation can lead to tire damage and sudden blowouts.

Controllo della pressione dei pneumatici:
- Ensure the tire is cold (driven less than a mile).
- Remove the valve cap from the tire stem.
- Firmly press the brass air chuck onto the tire valve stem. You may hear a slight hiss; this is normal.
- Il display digitale mostrerà la pressione attuale dei pneumatici.
- Remove the chuck from the valve stem.
- Sostituire il tappo della valvola.

Gonfiaggio dei pneumatici:
- Connect the inflator to your air compressor as described in the Setup section.
- Attach the brass air chuck to the tire valve stem.
- Press the "Push to Inflate" trigger (thumb trigger) to begin inflating the tire. The display will show the pressure increasing.
- Release the trigger periodically to check the current pressure reading.
- Inflate to the recommended PSI for your vehicle (found in your vehicle's owner's manual or on a sticker inside the driver's side door jamb).
- Once the desired pressure is reached, release the trigger and remove the chuck.
- Sostituire il tappo della valvola.

Sgonfiaggio degli pneumatici:
- Attach the brass air chuck to the tire valve stem.
- Press the "Push to Deflate" button (bleed valve) to release air from the tire. The display will show the pressure decreasing.
- Release the button periodically to check the current pressure reading.
- Once the desired pressure is reached, release the button and remove the chuck.
- Sostituire il tappo della valvola.
