3. What is the advantage of tire pressure monitoring system?

Answer:  Under-inflated tires need more fuel then properly inflated tires. It will save your money, ensure the safety especial during on the high way. 

4. Is low tire pressure easily detected by eye?

Answer:  Under inflated tires are visually difficult to detect. It is recommended that tires are inspected and checked monthly with an accurate gauge. The TPMS is not intended to be a substitute for regular tire maintenance.

5. Why does tire pressure change during driving?

Answer:  Many factors affect tire pressure including ambient temperature changes and tire damage such as punctures. Tire pressure drops about 1 psi for every 10 degrees F drop in ambient temperature. Additionally, tires lose as much as 1.5 psi per month as air escapes the tire and rim naturally.

6. Why there is no pressure and temperature readings on the LCD, only tire icon flashes?

Answer:  The sensors transmit the pressure and temperature every 5 minutes. The monitor will stop showing the pressure and temperature if it doesn’t get the signal from the sensors for over a hour.

7. What happens if I remove the sensors from the wheels?

Answer:  You will get a warning on your display screen. There is NO way to get rid of this warning except by deleteing the sensors code on the monitor.

8. How do I turn off the "low tire" warning in my dash?

Answer:  Inflate your tires with air to the acceptable PSI setting.

9. My TPMS warning light comes on when I start my car, but after a few minutes of driving, it turns off.

Answer:  In cold weather, the sensor reads a lower PSI. As you drive, the air within your tires warm up, and thus the pressure is also increased.

10. I just filled my tires with air a few weeks ago, and it is showing me that I have low pressure.

Answer:  A change in climate can affect the readings of the sensor because of the change in pressure of the tire. Climate affects the pressure within your tires.

11. How is the accuracy of the temperature readings on external sensors?

Answer:  It doesn’t have great value as pressure reading, as it may be reading ambient temperature.

12. If one sensor in the system stops working, is it possible to replace that sensor ?

Answer:  Yes, each sensor has a unique ID code, just program the new sensor to the monitor, the new sensor will replace the old sensor automatically.

13. Do I need to re-program the sensors after tires rotation?

Answer:  NO. Vehicles should have the tires rotated after running certainamount of miles, in order to ensure normal usage, just ensure you put the sensor on the original programmed tire position.

14.  Can I combine sensors or boosters from other manufactures with the EEZ RV PRODUCTS TPMS system?

Answer: It is not recommended to mix and match components from other systems. We cannot guarantee components from other systems will work properly or at all with each other.

15. Is it possible that sensors interfere with each other?

Answer:  As each sensor has its own unique code just like every car has it's own VIN number, and sensors transmit separately. It only takes very little time to transmit signals, there is extremely low probability that sensors interfere with each other.

16. What’s the transmitting distance from sensors and monitor?

Answer:  The TPMS transmitting distance for long vehicles can be up to 50 ft.

17. Is signal booster available? 

Answer:  Yes, we can provide optional signal booster for long vehicles if users want to make sure the monitor can read all sensors’ information.

18. Can I reset the monitor to factory settings? 

Answer:  Yes, to restore factory defaults, turn off the monitor, press the set button and turn on the monitor at the same time. The red light will flash and factory settings restored.

19. Do I need a signal booster (transceiver)? 

Answer:  It used to be easy to determine if you would need a Repeater/Booster and at that around 53 ft was a general rule we would look at. Now days though the big diesel pushers have so much electronics in the engine compartment they can get interference. As well as the structure of the frame and number of slides and metal on many of the new rigs of all styles can also be a factor. So you can get interference for issues other than distance. Systems will typically read fine sitting static, you won't see the interference until about 20-30 minutes into the trip.You can try it without first and if you experience any loss of signal add a Repeater. A Repeater can be added at anytime and only requires a 12V hot lead and a ground.

20. Does this system measure temperature as well as pressure? 

Answer:  Yes, unlike some systems from other suppliers that just measure pressure the EEZ RV PRODUCTS system measures internal  tire air temperature and has an over temperature alarm. This can be an advantage on vehicles that are stored for long periods of time where brake calipers can stick after the first brake application and cause a dragging brake situation. As well as a back up to the low pressure alarm as increased internal tire temperature is caused by low or reduced air pressure.

21. I am having code setting issues, what can cause those? 

Answer:  Coding issues can be caused by incorrectly sized or bent valve actuators or valves torque to tight or to loose in the tire valve stem thus not allowing the sensor to operate. For issues coding sensors on a tire with valve extenders, the sensor should be tested on a tire valve with no extender to help isolate the problem.

22. I have an alarm, what should I do? 

Answer:  First, pull over safely to the side of the road. Determine which wheel has an alarm, by checking the monitor icons, determine what type of alarm you have. It could be a leaking tire, a tire that has over pressure and too much air in it related to your base pressure setting, this can happen after a long run on a hot day, it could be an overheating situation etc. By checking the operating instructions you can see the different monitor icons that are associated with each condition, a flashing red light may or may not mean you have a deflation, each alarm icon tells you what the problem is. You will need to fix the problem before the red light will stop.

22. What is the Sleep Mode?

Answer:  If the monitor is motionless for more than 15 minutes (vehicle stationary) it will shut down to save the battery. When it detects motion again it will beep and the screen will come to life signifying it has come out of sleep mode. If the monitor is shut off overnight, simply switch the monitor back on prior to your departure and your real time tire pressures and temperatures will be updated in around 5 minutes on the monitor. Even if your monitor is in the sleep mode the system is always monitoring your tires and will alarm should any pressure or temperature become out of your set parameters.

22. I am getting a Sensor low battery alarm, what should I do?

Answer:  Eventually all batteries lose power or die. The EEZ RV PRODUCTS sensor has replaceable batteries that can be easily replaced whenever needed. Please see above for detailed directions. The battery is a CR1632 watch type battery available from jewelry stores, electronics stores or on-line.

23. How can I test the system?

Answer:  The system should be frequently tested for fast leak operation. The monitor should be placed in the driver’s location and sensors unscrewed then tightened one at a time. The fast leak alarm should operate and then reset on the monitor.

24. Do I need a special tool to install the sensors?

Answer:  The EEZRV PRODUCTS system comes with a complimentary Anti-Theft System on each sensor. In order to install a sensor you will have to use one of the 2 wrenches provided. You can easily remove the Anti-Theft Function by removing the 3 small screws on the bottom of the sensor, this will allow you to install the sensor by hand with no wrench. This can be beneficial when installing a sensor on your inside dual.

25. Can I set different pressures for each tire or axle?

Answer:  Axles can be set to a different pressure, for tow & towed vehicles.

26. Can I use tire valve extensions?

Answer:  Most tire valve extenders work ok, however if you have problems with sensors mounted on extenders, test the sensor on a regular valve stem location to see if it is a sensor problem or an extender problem. Alarms can sometimes be caused by loose extender connections.

27. How accurate is the system?

Answer:  Our sensors are very accurate and any gauge readings should be made after resetting the sensors. Measurements of 1psi need a controlled laboratory type system to be accurate. The tire pressure is accurate within +/- 1.5 PSI. Temperature is accurate to within +/- 5 degree F. The pressures and temperatures can vary dramatically from wheel to wheel depending on many factors, such as sun shining on one side, vehicle load, castor/ camber/alignment/brake temps. Even race cars turning left all the time generate higher pressures and temps on one side. Tire gauge accuracy can vary wildly and their quality is not dependent on their cost. Temperature compensation is a requirement in a good gauge. (gauges that read the same at -40 & 110 degrees) slide type gauges that rely on friction are often inaccurate.

28. How much air do I put in my tires?

Answer:  Always set the monitor pressure to the same as the cold inflation pressure. As an example some people set the monitor at 100 psi and then put 105 psi in the tire for good luck, by doing this the chance of over pressure alarms is increased.

29. Can I use the sensors on rubber valve stems?

Answer:  Steel valve stems are ultimately recommended. It is not recommended using the Flow Through (2 1/2 inch) on a rubber stem. It is recommended you use rubber valve stem supports on your rubber stems. There are 2 types; one that goes over the rubber stem and clips onto the edge of the rim, the other that adheres to the rim and support the rubber stem from the side. You can do a Google search for "rubber valve stem support." The primary issue with rubber stems is where the rubber stems come through the metal rim. With extra wear and vibration the rim can start to cut into the valve stem. You always want to make sure on your walk around to wiggle the rubber stems and listen for air leakage through any stem, particularly where it comes out the rim.There are many variables that can affect your decision whether to use a sensor on a rubber valve stem, with every rig it can be different: its tires, weight, load distribution to name a few.  When ever you have a question regarding your tires we always recommend you consult a tire professional to determine what is best for your rig.

30. I get an alarm when I have been stopped for a while?

Answer:  In extreme cases it is possible to get a slow leak alarm after the vehicle has been pushed hard and the tire pressure has dramatically increased and upon stopping the tire cools quickly and the pressure drops simulating semi rapid air loss. This situation is often caused by high moisture content in the air in the tire.

31. How is my monitor powered?

Answer:  The monitor is powered by an internal rechargeable battery which holds a charge up to 60 hours before requiring recharging. A cigar lighter cord AND hard wire kit comes with the base system, this means you can take the monitor in your hand around your vehicle for sensor setup and tire pressure adjustment, it is like having an electronic tire gauge

32. Does the system come with a warranty?

Answer:  Yes, it comes with a 3 year limited warranty on defective parts except batteries. Please see warranty section for full details.

33. Do I have to enter special codes for each sensor on set-up?

Answer:  Each sensor comes pre-programmed with its own unique code,  for sensor set up the monitor detects each sensors code when they are installed.

34. Is there anything special I need to do for Winter Storage?

Answer:  It’s a good idea to remove the sensors and monitor from your vehicle if parked for an extended time, especially in cold weather. Store the system  in a warm location. Mark each sensors wheel position or store them in an egg carton so they can be replaced in the same wheel position to avoid having to do a new set up. Sensors do not use power when they have no pressure on them .

1. What it does?

Measures the air pressure and temperature within the tire to ensure that it is properly inflated.

2. How does it work?

Answer:  Tire pressure monitoring systems continuously monitor the pressure in the tires through sensors located in the tires (direct system). The information collected by the sensors is transmitted to an on-board monitor that real time displays the tire data and warns the driver when tire pressure or temperature is outside of the preset level.
