FAQ
Q1: Does it replace my car’s TPMS?
A: It’s a quick visual aid, not a digital TPMS. For precise values, use a gauge or your vehicle’s system.
Q2: Will it leak air?
A: The internal gasket provides an airtight seal when properly installed on an undamaged valve stem.
Q3: Can it stay on in winter?
A: Yes. Stainless steel and copper core resist high/low temperatures and road salt.
Q4: How do I choose the pack size?
A: 4-Pack for one car, 8-Pack for two cars or spares.
