A TPMS, or tire pressure monitoring system, can be a huge asset when it comes to RV safety. The industry is well known for providing low priced (and too often, low quality) tires on their RVs when leaving the factory. Those tires are rated for lower speeds, and can easily be damaged by driving to fast for the tire’s speed rating. That’s why it is important to do an RV TPMS review, if you haven’t already.
RV TPMS Comparison
Knowing your tire pressure will help you travel safely. A TPMS system will ensure you may see the signs of a blowout before they happen. You can also confirm the tire is riding according to factory specifications, which will help prevent overheating.
A TPMS can help you save money too. If your tires are hot they are going to expand and the PSI inside the tire will increase. This doesn’t always mean a blowout, but it can mean there is an alignment issue with your axle. When the pressure is steadily reading high its going to be a good time to check your tires. A tire will show signs of wear on the inside half of the tire when there is an issue.
RV TPMS Systems
The TPMS kit you need is going to depend on the number of wheels on your trailer. A triple axle fifth wheel needs a 6 sensor kit, while double axle fifth wheels & most large travel trailers need a 4 sensor kit. Your tow vehicle should have its own TPMS built in, so no need to purchase for those wheels too. Again, a TPMS for RV-ers does not need to include your tow vehicle wheels.
The B-QTech Wireless TPMS Kit shown above is a quality TPMS kit for under $200. (Check price on Amazon) Its definitely not a kit that is built to last, but for the occasional RVer its a great value. This is a plug and play system that will be easy to install. The downside will come from reliability. I recommend immediately changing the batteries as a full battery seems to improve reliability. Some of the less flattering reviews indicate this unit will suck the batteries down quickly in your sensors.
There may be stretches of roadway that the TPMS is not giving a reliable reading due to signal strength. Again, this can be related to the batteries, so always make sure you keep a spare set on hand. The sensors are cap sensors instead of flow through, so your valve stem material can be metal or rubber, which is nice.
flow through vs cap tpms
There are two very popular types of sensors for your tire pressure monitoring system (TPMS). The flow through sensors allow you to put air in your tire without taking them off the valve stem. Flow through sensors are larger, and the centrifugal force overtime will definitely wear on your valve stem.
The flow through TPMS sensors need to connect to a metal valve stem. If your rig is using rubber valve stems you will want to go with a cap sensor instead of a flow though.
The cap sensors are slightly smaller, this creating less centrifugal force and less wear and tear on your valve stem. I prefer cap sensors for our TPMS, but I completely understand why someone would like flow through sensors if they have metal valvestems.
If you are looking for a TPMS made to stand the test of time, the Eez-Tire TPMS is incredibly well reviewed, and we know several full-time RVers that use it. This is a cap sensor kit. Its a bit more expensive (check current price on Amazon) but it should last longer than the B-Qtech. More importantly it is far more reliable.
