In today’s vehicles, technology plays a crucial role in keeping drivers safe—and one of the most essential safety features is the Tire Pressure Monitoring System (TPMS). This system keeps track of tire pressure in real-time and alerts the driver if any tire falls below the recommended level, helping to prevent blowouts, improve fuel efficiency, and extend tire life.
If you're replacing TPMS sensors, one question often comes up: Should you go with OEM (Original Equipment Manufacturer) sensors, or choose aftermarket alternatives? Below, we’ll explore the differences, weigh the pros and cons, and help you make an informed decision.
Understanding TPMS Sensors
TPMS sensors are typically located inside each tire, either attached to the valve stem or mounted on the wheel. These sensors monitor the tire pressure and send data to the vehicle's onboard computer. If a tire is under-inflated, the TPMS warning light on the dashboard will illuminate.
There are two main types of TPMS:
-
Direct TPMS, which uses sensors inside each tire.
-
Indirect TPMS, which estimates pressure through wheel speed data (less common in newer vehicles).
For the purposes of this comparison, we’ll focus on direct TPMS, as these are the sensors most commonly replaced and available in both OEM and aftermarket forms.
OEM TPMS Sensors
OEM (Original Equipment Manufacturer) sensors are made by the same companies that supply parts to vehicle manufacturers. These sensors are designed specifically for your car’s make and model.
Advantages:
-
Guaranteed Compatibility: OEM sensors are programmed to work seamlessly with your vehicle’s onboard systems.
-
Proven Reliability: They are tested to meet manufacturer standards for durability and accuracy.
-
Dealer Support: If something goes wrong, the dealership can easily diagnose and replace the part.
Disadvantages:
-
Higher Cost: OEM sensors can range from $50 to $100 per sensor, not including installation.
-
Limited Availability: You may need to visit a dealership or authorized parts supplier.
-
Less Flexibility: OEM sensors are vehicle-specific and cannot be used across multiple makes/models.
Aftermarket TPMS Sensors
Aftermarket sensors are produced by third-party manufacturers and are often designed to be compatible with a wide range of vehicles. Many reputable brands offer high-quality alternatives to OEM parts.
Advantages:
-
Cost-Effective: Typically priced between $20 and $60 per sensor.
-
Wide Availability: Can be purchased online or at most auto parts stores. Go here to easily purchase from a2iwheelandtire.com
-
Programmable Options: Universal sensors can be programmed to fit many vehicles with the right tool. Ours are easy to program - but we can also program them for you.
Disadvantages:
-
Varied Quality: Performance and durability can vary widely depending on the brand.
-
Compatibility Risks: Some sensors may not communicate correctly with your vehicle’s TPMS module.
-
Programming Required: Many aftermarket sensors need to be manually programmed, which can require specialized tools or professional help.
Cost Comparison
| Sensor Type | Average Price (Per Sensor) | Compatibility | Programming Needed |
|---|
| OEM | $50–$100 | Vehicle-specific | Usually pre-programmed |
| Aftermarket | $20–$60 | Multi-vehicle (universal or semi-universal) | Often required |
Keep in mind that installation and reprogramming (especially at a dealership) may add an additional $20–$50 per wheel, depending on your location.
Which Should You Choose?
Go with OEM if:
-
You drive a newer or leased vehicle and want to maintain factory standards.
-
You prefer a plug-and-play solution with guaranteed results.
-
You’re having the replacement done at a dealership or want full warranty coverage.
Go with Aftermarket if:
-
You're budget-conscious and don't mind a little DIY or third-party assistance. (Contact A2i Wheel and Tire for any questions at 616-330-6600)
-
Your vehicle is older or out of warranty.
-
You’re confident using a TPMS programming tool or working with a trusted mechanic.
Final Considerations
Before purchasing any TPMS sensor, be sure to:
-
Verify compatibility with your car’s year, make, and model.
-
Check sensor frequency (typically 315 MHz or 433 MHz, depending on the vehicle).
-
Stick to trusted brands—A2i Sensors are guaranteed - or your money back.
-
Consider battery life—most TPMS sensors last 5–10 years, after which the entire sensor must be replaced.
Conclusion
Both OEM and aftermarket TPMS sensors have their place in the automotive world. While OEM offers peace of mind through guaranteed performance, aftermarket sensors provide flexibility and cost savings for those willing to do a little extra research or programming.
Ultimately, the right choice depends on your priorities—whether it's precision and factory fit or affordability and adaptability.
If you're not sure which type is right for your situation, consult a trusted mechanic or tire technician. Either way, maintaining a functioning TPMS is vital for your safety, fuel economy, and tire health.
