4. Cacagoo Wireless TPMS
Boasting a larger display than other products is Cacagoo’s wireless TPMS kit. Along with real time pressure monitoring and high temperature warnings, this system also monitors your vehicle’s battery voltage and offers visual and audible warnings. The wide-angle LCD screen measures 3.15 inches by 1.5 inches, allowing you to quickly glance and see all the relative data easily. The display can also be mounted on your windshield using a holder, rather than being restricted to your cigarette lighter receptacle.
Although these sensors use the same CR1632 batteries as other kits, Cacagoo claims the battery life will last around five years rather than the two years its competitors advertise, when using a 120 mAh battery. The sensors monitor up to 116 psi and each sensor is IP67 rated, which means its sealed against dust, water, and snow. Pressure accuracy is within 1.5 psi. The default alarm is set to 29 to 44 psi, but it can be configured by the user.
Unlike other systems, this one will display tire temperature in both Fahrenheit and Celsius, along with tire pressure in psi or BAR.
This kit is suitable for conventional vehicles such as sedans and passenger cars, as well as SUVs, minibuses, commercial cars, station wagons, and off-road vehicles. It should not be used on motorhomes, caravans, RVs, or trailers. The company offers a 24-month warranty with this system.
Each system comes with four external sensors, four tire valves, one holder, one cigarette lighter, one spanner, one charger and power line, and one instruction manual.
Pros/Large screen, temperature display in Fahrenheit and Celsius, monitors up to 116 psi, IP67 rated sensors, can be mounted on your windshield, 24-month warranty
Cons/Few complaints of failed sensors, a bit tricky to setup
5. ENKLOV Wireless TPMS
Another system with a larger display is offered by ENKLOV. Like Cacagoo’s system, this one has an easy-to-read LCD display that can either plug into your cigarette lighter receptacle, or mounted thanks to the included holder and car charger cable. The display offers real time tire pressures and temperature, offering visual and audible alerts if pressure goes under or over a certain range.
These sensors monitor up to 116 psi and promise to deliver accuracy within 1.5 psi. Like other kits, this one is recommended for use with most passenger vehicles and not on RVs, trailers, or trucks. Battery life on the sensors is advertised to last around three years, based on four hours of driving per day. The batteries are replaceable, while the sensors are waterproof and feature an anti-theft design.
Each kit includes one tire pressure and temperature monitor, four external sensors, one hexagon nut wrench, four hexagon nuts, one cigarette lighter connector, one open end wrench, one holder, one car charger, and one instruction manual.
Pros/Larger LCD display, monitors up to 116 psi, can be either mounted or plugged into your cigarette lighter receptacle
Cons/Some users report sensor caps cause tires to leak, display is difficult to read in sunlight, slightly confusing setup
What is a Tire Pressure Monitoring System?
Simply put, a tire pressure monitoring system provides real time readings of your tire pressure. Kits offered by the aftermarket are generally affordable and easy to install and are the best way to add TPMS to an older vehicle. Some factory systems will only give you a warning light when one of your tires are low on air, which isn’t as accurate as displaying actual values for each tire – although some modern vehicles do feature a system that gives individual readings.
The aftermarket kits normally use sensors that are installed onto the valve stem of your wheel, along with a display that you have inside your vehicle. Some of these displays use your cigarette lighter receptacle for power, while others can run a cable and be mounted to your dash or windshield. These systems allow you to set a tire pressure range and they will warn you if your tires go below or above that range. In addition, some kits also monitor other information such as tire temperature and even your car’s battery voltage.
Why do I Need a Tire Pressure Monitoring System?
Knowing the pressure in each of your tires is important not just for safety, but for fuel economy. Overinflated and underinflated tires can affect your car’s performances, especially the fuel it consumes. In addition, TPMS can warn you ahead of time if you have a slow or fast leak, prompting you to check for possible punctures in your tires.
So why is knowing your tire pressure so important? Underinflated tires have increased surface contact, which means premature tire wear. Underinflation also has a direct effect on a car’s fuel economy, which means you’re wasting money when driving on underinflated tires. Overinflated tires cause rigidity and stiffness, resulting in a harsher ride in your vehicle. This also means contact with the road is increased around the center area of the tire, resulting in additional wear in the center.
Since TPMS kits are rather affordable and easy to install, it’s a minor investment towards long-term savings. Replacing your tires isn’t cheap and can take some time out of your day, so it’s best to keep them properly inflated so they last as long as possible.
Our Final Verdict
Truth be told, many of these aftermarket TPMS kits are very similar in features and specifications. It’s very likely many of them come from the same manufacturer overseas, which means they’re just marketed and branded differently in the U.S. That makes it difficult to recommend an overall best product for this category, especially since it also comes down to whether you want a compact or large display inside your vehicle.
What we do suggest however is to choose a product that offers a warranty and check user reviews to see how well that specific company’s customer service is. Overall, many of these products should perform similarly and pricing doesn’t range significantly from one product to another. So pick one that will cause less headaches if you do run into issues with it.
