tpms 자동차 용품

Looking for a TPMS (tire pressure monitoring system)? This search finds internal TPMS sensors, external valve-cap sensors, and aftermarket display kits.

What to look for in a TPMS

TPMS warns you of underinflated tires that hurt fuel economy, handling, and wear. Factory systems alert on low pressure only; aftermarket systems can show per-tire pressure and temperature.

Quick checklist

• Type: internal sensors (replace valve) vs external (valve-cap, easier install).
• Display: dashboard display vs phone app vs windshield mount.
• Sensor frequency: match your vehicle's frequency (315 MHz or 433 MHz).
• Batteries: internal sensors last ~5 years; external caps are user-replaceable.
