In case you’re not sure what the beast actually is, tire pressure monitoring system (or simply TPMS) serves the important purpose of warning you in case one or more tires are significantly under-inflated, which means potentially hazardous driving conditions. Ever noticed a yellow symbol that resembles a horseshoe (well, it’s actually a tire cross-section), illuminating on the dashboard instrument panel? That’s your TPMS low tire pressure indicator.
What seems like a little feature now in the age of fancy GPS navigators and auto-parking systems was actually a major life saver at a time! Before tire pressure monitoring systems became commonplace, drivers never knew for sure if the air pressure had reached unsafe levels or not. To check it, you would need to get out of the vehicle, crouch down and use the dreaded tire gauge.
As you’ve probably guessed, ain’t nobody got time for that. As a result, before the widespread use of these helpful devices, many potentially avoidable car accidents happened as a result of drivers not being aware of low tire pressure. Crashes still happen because of this, however proper tire maintenance does reduce the rates considerably, thanks to the invention of a TPMS.
Unfortunately, there is no ultimate quick fix when it comes to tire pressure monitoring and maintenance. Tire pressure will most definitely get out of spec at some point, and it’s important to keep this process under control. Sometimes it happens suddenly, but more often than not – gradually over time, unless the dreaded blowout happens. Broken glass bits and other road hazards, weather conditions and other unfortunate yet unavoidable events lead to your tires inevitably losing pressure over time. The nature of rubber itself – namely, the pores in its structure – is enough on their own to lose a couple of psi per month.
In case safety considerations don’t scare you enough, there is also a monetary side of tire pressure loss. As tires deflate, they start resisting against the road surface more and more, leading to increased fuel usage, which will cost you a lot in a long run.
If you need to purchase a new TPMS, there are many factors to consider, as they don’t all work the same way! If you’re looking for the best tire pressure monitoring system, make sure to read through our buying guide below. To help you make a choice, we are also including a number of RV TPMS reviews, which will guide you on your way to your perfect investment.
Simply read the comprehensive material below, and don’t hesitate to contact us if you have any further questions.
First thing you’ll need to decide on is if you want an indirect or a direct RV TPMS system, as some of the best trailer tire pressure monitoring systems may be found in both categories.
- The indirect system uses the Antilock Braking System of the vehicle to measure the degree of wheel rotation. The system indicates that deflation has occurred in case one wheel starts spinning faster – this triggers the warning.
- The direct system works differently – it uses a set of wireless sensors in each wheel. These sensors are able to measure tyre pressure directly, and the information is then transmitted to a display unit. In case tyre pressure drops below a certain pre-determined point, the warning message pops up.
Of course, it’s easy to conclude that direct systems tend to be more accurate compared to indirect counterparts – however, this comes with an increased cost. When making a choice, you need to carefully consider if you need this level of accuracy – the answer is likely to be yes if you are a frequent traveller, for instance.
Apart from the type, there are some features to consider that may influence your choice, including:
- Maximum number of sensors – for RVs it’s better to pick systems that allow for extra sensors to use with caravans and trailers
- Temperature range – you need to make sure it’s possible to adhere to these recommendations within your vehicle
- Pressure range (most often in psi), which indicates the range of pressures at which the sensor is claimed to be accurate. Be sure to check what range is suitable for your needs – some caravans and trailers require over 50psi, and not every system out there will support such values.
- Type of the sensor battery used, and if the replacement is easily accessible
- The presence of a fast air leak detector. This sensor detects fast leaks and quickly generates alerts, potentially giving you time to slow down or stop safely before something seriously bad happens.
When comparing the characteristics while browsing RV TPMS reviews, pay particular attention to:
- Sensor accuracy
- Quality of the display and how easy it is to collect the readings quickly and accurately
- Ease of use – for instance, how easy it is to adjust tyre pressure if required.
Now that we know what to look for, it’s about time to review some models to help you find the best trailer tire pressure monitoring system to suit your needs! We are including a number of comprehensive RV TPMS reviews below for your convenience.
EEZTire Tire Pressure Monitoring System
Retailing for $450-$500, this beast has not 4, not 6 but 10 sensors! It’s extremely reliable and unbelievably easy to install. The device features a large LCD screen, which won’t die on you thanks to a built-in rechargeable lithium battery. Thanks to a large number of sensors, this TPMS takes care of up to 22 tires maximum. It also has an automatic backlight for your convenience. You can easily configure high/low pressure and temperature warnings, and there is a long range between sensors and monitor. Selectable pressure units, visible and audible alerts – what more to wish for? There are some drawbacks you need to be aware of, though – for instance, the system is programmed to take an hour or so before it reports that it has lost the signal from the sensor, so basically the information you’re getting is along the lines of “an hour ago your tires were OK”. Another thing is, sensors don’t fit certain valves, so make sure to study the specs vigorously before purchasing.
TireMinder A1A Tire Pressure Monitoring System
One of the best trailer tire pressure monitoring systems out there, TireMinder A1A will set you back around $420-450. Just like the previous model we’ve reviewed, it can monitor up to 22 tires at 0-232 psi, which is quite an impressive range. It has a number of other impressive features, such as 0.5 oztransmitters screw on valve stems, separately displaying psi and temperature for each tire and a range of alarms. Speaking of alarms, TireMinder A1A has blow-out alarms, as well as visual and audible high/low pressure alarms. Any cons? Some customers complain about receiving faulty items with bent antennas and failing transmitters. If this happens to you, rest assured that the customer service is outstanding, so your issue will likely be fixed in no time.
Tst 507rv TPMS
If you’re on a budget, this ~$300 TPMS may be the right choice for you. Some of the features include a flow through sensor (which means you can add air to the tire without taking off the sensor, as the sensor acts like a valve cap) and replaceable batteries. It continuously monitors and displays psi and tire temperature on a rotating basis of each tire, which is very handy. As the price point is quite low, it’s no surprise that there are more complaints about this guy compared to fancier systems. For instance, some customers note that sensors tend to leak air from the tyres. In addition, charging this system is not exactly a breeze…
Tire safeguard tire pressure monitor review
If you hurry, this usually pricey TPMS will cost you about $280-300 at the moment, as it seems to be on sale from many retailers. This model features a portable monitor with rechargeable battery, detecting tire pressure 0-199 psi as well as temperature. The flow-through sensor with replaceable battery can be secured to prevent unpredictable events such as loss or theft. With this TPMS, you can monitor tires literally 24/7, and all sensors and thresholds are user adjustable. This model doesn’t really have downright negative reviews – although some customers point out it’s not very easy to install, and extensions for it are not widely available.
Now that we’ve considered some RV TPMS reviews, it’s time to go through a couple of brands and point you in the right direction, so you can get the best trailer tire pressure monitoring system possible.
Eeztire vs Tireminder TPMS
Those seem very similar, but customers who used both seem to lean towards Eeztire. Those are on a more expensive side, perhaps, but their range is truly amazing. They have provisions to monitor both the RV and the towing vehicle if you need it, and the brand also features two types of sensors to suit your needs. Happy customers point out that purchases from this brand are extremely reliable, working for many years with no issues. On the other side, TireMinder systems do have a number of amazing features, including compact easy to use monitors and no vigorous cycling through the tires unless you need it.
TST vs Eez TPMS
Now, TST features much more budget models compared to the latter, so if money is a concern, you will likely find yourself leaning towards TST. Pretty much everything is outlined above – but there is, however, an additional factor to consider. With TST, there was an ongoing issue of brass sensors corroding on stainless steel tire valves. In some cases, the corrosion was so bad people had to replace the valve stems because they could not inflate their tires. If you want to avoid this possibility, perhaps stick to Eez.
Hopefully, after reading this material you no longer need to be convinced of the crucial role tires play in your RV! Holding up such a large vehicle is no jokes, and well maintained tires are absolutely required for safe and enjoyable adventures. Putting it simply, safety first!
To ensure your safety, please consider purchasing the best trailer tire pressure monitoring system you can afford, unless your vehicle has one preinstalled. Even if the latter is the case, when the time comes to change your TPMS, you can always go back to our RV TPMS reviews and refresh important points to consider.
