Is TPMS required when replacing tires ?
Whether TPMS (Tire Pressure Monitoring System) is required when replacing tires depends on your vehicle's original equipment and local regulations. Here’s a clear breakdown:
1. Legal Requirements (By Country)
1) USA (DOT Regulation):
- All vehicles manufactured after 2007 must have TPMS.
- If your car originally had TPMS, you must maintain or replace it when changing tires.
- Exception: If you’re swapping wheels/tires temporarily (e.g., winter tires), but the original TPMS-equipped wheels must still be functional for road use.
- EU/UK:
- TPMS is mandatory for all new cars since 2012.
- Non-compliance may fail MOT (annual inspection).
- China:
- Required for all new passenger cars since 2020 (GB 26149 standard).
- Other Countries:
- Check local laws (e.g., Japan, Australia require TPMS in newer vehicles).
2. Do You Need to Replace TPMS When Changing Tires?
| Scenario | Action Required |
| TPMS already equipped | Yes – Reuse or replace sensors if damaged/old (typical lifespan: 5–10 years). |
| Aftermarket wheels/tires | Ensure compatibility – New wheels may need sensor adapters or replacements. |
| Older car without TPMS | No – Not legally required, but adding aftermarket TPMS improves safety. |
3. Consequences of Ignoring TPMS
- Warning Light: Dashboard alert will stay on.
- Safety Risk: Losing real-time pressure monitoring increases blowout risk.
- Inspection Issues: May fail annual safety checks (e.g., U.S. state inspections, EU MOT).
4. Cost to Replace TPMS
- OEM Sensors: $50–$150 per sensor (varies by brand).
- Aftermarket Sensors: $25–$80 each (e.g., Schrader, Autel).
- Labor/Programming: $20–$50 per wheel (some shops include it with tire installation).
Total for 4 Tires: ~$200–$800 (depending on sensor type and labor).
5. Practical Tips
- Reuse Sensors: If they’re in good condition, just transfer them to new tires.
- Bundle Services: Many tire shops discount TPMS work when buying new tires.
- Aftermarket Kits: Cheaper than OEM (ensure compatibility with your vehicle).
Bottom Line
- If your car came with TPMS, you must maintain it when replacing tires.
- No TPMS originally? Optional but recommended for safety.
