TPMS Tyre Pressure Monitors

What Are The Best Tyre Pressure Monitoring Systems

Tire pressure monitoring systems have been a mandatory requirement in the US since 2008. This is when the federal government declared that all cars made and sold in the US must be fitted with these systems for safety purposes.

If you have a vehicle which was made before 2008, you will probably want to install a TPMS system. On the other hand TPMs sensors have a typical lifespan of 5 to 10 years. This means that sensors in vehicles continually need replacement as their lifespan ends.

This is where aftermarket TPMS sensors come in. These are sensors which are designed for use as replacements for sensors installed during manufacture of a vehicle. Aftermarket sensors are typically cheaper than original (OEM) sensors.

To help you make an informed decision on which sensors to buy, we have compiled a list of the best aftermarket TPMS sensors.

Factors to Consider When Buying Aftermarket TPMS Sensors

Sensor type:

There are two types of TPMS sensors in the market.

Indirect TPMS sensors

These work by monitoring the rotational speed of each wheel. The assumption is that an underinflated tire has a slightly reduced diameter and higher rotational speed than a properly inflated one. When a tire is underinflated, these changes are detected using the ABS system.

Direct TPMS sensors

In the direct system, TPMS sensors are fitted in each wheel and they physically measure tire pressure and report it to the vehicle’s ECU. Some sensors also measure and report temperature changes in the tire.

Some systems can report under inflation in varying combinations. Some report it in general and others report it based on individual tires.

Battery Durability:

TPMS sensor batteries generally last very long. However, some last longer than others and it is important to select one which will give you the best service for the longest time.

Another factor to consider in relation to batteries is the independence of the battery from the rest of the sensor. Some sensors have removable batteries which can be removed and replaced while retaining the sensor. Just like you would do with your remote control. In other sensors, the battery cannot be replaced. When it fails, the whole sensor must be replaced.

Cost effectiveness:

A quick look through TPMS systems and sensors will reveal that some sensors are sold as single pieces, others are supplied in pairs and others are sold in sets of 4.

Take time to do the math and figure out what the most cost-effective option is. A TPMS sensor brand may seem more expensive than another but you find that it supplies 4 sensors in a pack. This effectively makes them cheaper than single sensors.

Versatility:

Some sensors are vehicle specific and others are not. When buying sensors, look for a brand which can be used on a variety of makes and models. This is especially true if you are buying sensors to stock at an auto repair shop. You want to have sensors which can be used on almost all, if not all clients ‘vehicles.

Frequency:

TPMS sensors generally transmit on one of two frequencies. These are 315MHz and 433 MHz.  The difference is basically in terms of geographical area. 315MHz is not permitted in Europe while in the US, both 315MHz and 433 MHz are permissible.

For this reason, most dealers choose to stock 433 MHz frequency sensors because they are internationally accepted and usable. Always check the transmission frequency used before you buy.

Reliability:

Take time to do some research to find out the leading names in the industry. Try to stick to these when you buy. The assumption is that a leading brand of TPMS sensors will supply good quality sensors.

Another advantage you are likely to enjoy when you buy from reputable manufacturers is customer assistance. Larger, reputable companies usually have professional customer care services to assist you if you have any problems with the product.

Ease of use:

TPMS sensors are a part of the entire tire pressure monitoring system. They can be used using an inbuilt monitor in the vehicle or a portable monitor which you have to operate like any other device.

Look for sensors which are compatible with monitors which are easy and convenient to use. If you cannot use the monitor then the whole purpose of the TPMS system is defeated.

Warranties:

Some TPMs sensor brands come with warranties which assure you that the product will be replaced if you encounter quality-related problems. The warranty period could be given in terms of time such as one year or two years. It could also be expressed in terms of mileage. In this case you can have the sensor replaced for free if it develops problems before you have covered a certain number of miles.

It is easy to ignore warranties when purchasing a product but if you have ever had a faulty product replacement on the basis of a warranty, you know how important they are. On the other hand, warranties should give you confidence that a product is of good quality.

Any manufacturer who is confident enough to offer a warranty on their product is certain it is good enough not to attract a significant number of replacements.

Conclusion

Replacing your TPMS sensors after the ones the car came with fail can be somewhat confusing. There are so many brands to choose from and you have to make sure you buy a brand which is compatible with your car.

After an analysis of different brands, the Autel MX TPMS Sensor is our top pick because it comes in a set of 4 inexpensive sensors for easy replacement of all four sensors in a regular car.

They are 100% ID clone-able and have a durable battery. Another advantage to enjoy is an impressively high vehicle coverage percentage (98%) which is thanks to Autel’s efforts to stay updated on new vehicle models. A 24 -month or 24,000 mile warranty is great to have even if you never make use of it.
