Cayenne checking in with you,
Under-inflated tires waste gas for lots of folks in the Cupertino area. Think how hard it is to walk in sand – you just have to work harder because of the resistance. When your tires don't have enough air in them, their rolling resistance is dramatically increased and it simply takes more gas to get from Los Altos to Cupertino.
Always check your tire pressure when you gas up at one of our local Cupertino service stations. If they're low – even just a little bit – bring them up to proper pressure. There's a sticker on the inside of your driver's door that gives the manufacturer's recommended tire pressure.
And don't rely on your tire pressure monitoring system to alert you to when you need more air. The TPMS system is set to warn you when pressure drops twenty percent below recommendations. That's severely under inflated and you needed more air a long time ago. And if you have a slow leak – get it fixed right away at Allied Auto Works.
Get some air and save some gas.
