Can I monitor both the RV and the towed vehicle tires?
Yes. PressurePro™ will simultaneously read the largest size RV and the vehicle it tows.
PressurePro™ will work on all types of vehicles (boat trailers/horse trailers, trucks, RVs, cars, etc.) with up to 34 wheel positions, if needed.
More about how PressurePro™ monitors tire air pressure.
Will PressurePro work if I already have a tire pressure monitoring system on my car?
Yes. The TPM system that comes with your car is internal in the wheels and will not interfere with the externally mounted PressurePro Sensors.
So if you have a motor home or truck, and you pull a vehicle behind, PressurePro will monitor both vehicles, regardless of whether or not you already have a system on your car.
How strong is the signal?
PressurePro™ Sensors will transmit up to 100 feet under most conditions.
PressurePro™ complies with all regulations and FCC guidelines.
The signal from the Sensor is specific to the receiver, which is tuned for sensitivity to the Sensor signal. Read More.
Can I store my vehicle with the Monitor on?
The Monitor draws 25mA to 150mA of power. It’s possible the Monitor could drain the vehicle's battery, but it would be over an extended period of time. If storing for more than 6 months without charging, it is advised to unplug Monitor and remove Sensors. Plug in Monitor before driving again. Storage Tips.
Does the Monitor need to be powered by the lighter recepticle?
No. Although the cigarette lighter plug comes with the system, hardwiring is an even better option, as it reduces feedback interference and inadvertent disconnects at times.
The Monitor can be unplugged from the hardwire receptacle and can then be used in another vehicle for a day trip, for instance, using the cigarette lighter plug. Merely remove the Sensors, keeping them in the same respective locations (see Storage Tips) and put them on the car or boat trailer, etc.
Can the Monitor be used independently on the front or back vehicle?
Yes, use the "F/B" (Forward/Back) button on the Monitor when separating a vehicle from the tow.
There are three pushes to this button. Press the button the first time: all tires with Sensors will light on the Monitor; press F/B button again, until just the vehicle depicted wheel location you want to use displays on the Monitor; it will Monitor that vehicle only. Press the F/B button again to connect both vehicles.
What is the "reminder" alert?
PressurePro™ will alert firstly when there is a 12 1/2% pressure loss from initial pressure at installation. One can "mute" the audible alert by presssing the "ON" button which puts the Monitor in "reminder mode".
A second stage low pressure alert will then "beep" when the pressure becomes 25% below the accessed pressure, flash tire location, and display the pressure value twice per second.
If no button is pressed to mute the system, the system will alert untl the low pressure is corrected, or for a total of 15 hours. An advantage of this feature is that one can watch the Monitor to determine if the tire has a slow leak or a fast leak.
One can actually pump up the tire with a portable compressor and continue to drive until a better tire-fix location is reached. This ensures "fixing" the tire rather than "replacing" it.
What do I do about a low Sensor battery alert?
When you receive a low Sensor Battery alert (you will have approximately two weeks of Sensor use remaining) contact L&S Safety Solutions LLC at 800-521-6820.
The Sensors are sealed units and batteries are not replaceable by the customer; when the system indicates low Sensor battery power, a new Sensor should be ordered.
For most vehicles including RVs and trucks, Sensor batteries are expected to last for approximately 4-5 years; the Monitor will tell you which Sensor battery is getting low. You will then exchange/replace the entire Sensor with anyone who sells PressurePro™ , and receive a new Sensor with a new battery for the price of the battery only.
Sensors do not need to be replaced all at once--if a Sensor has set off an alarm, that one is likely to need replacing first.
What should be done if a low pressure alert is sounded?
If moving, Immediately pull over and check low tire. Physically check tire, determine the cause, and repair.
However, one of the advantages of the PressurePro™ system is that one can watch the Monitor to determine if the tire has a slow leak or a fast leak. One can actually pump up the tire with a portable compressor and continue to drive until a better location for fixing the tire is reached.
Fixing a tire is less costly than buying a new one and/or repairing your vehicle! If parked, physically check tire and repair.
Yes, PressurePro™ monitors while parked!
What makes my system Sensors transmit?
Sensors will transmit data to the Monitor under the following conditions:
- Sensors update every 5 minutes. However, if there is a
low-pressure tire, an alarm over-rides the 5 minute update. When a tire
loses 12 1/2% psi, the driver will immediately be notified by an alarm.
The Monitor will blink the location of that tire and will read out the
pressure in the window.
- Air pressure has dropped below 12.5% of the reference value
for tire’s pressure at time of installation. Normal mode pressure
transmission reporting takes place every 5 minutes. However, if there is
a low-pressure tire, an alarm over-rides the 5 minute update. When a tire
loses 12 1/2% psi, the driver will immediately be notified by an alarm.
The Monitor will blink the location of that tire and will read out the
pressure in the window.
- Air pressure has dropped to the second alert level, 25% under the original reference pressures. This alert transmits on a regular basis until low pressure situation is corrected.
- A Sensor is removed from its tire.

How do the Sensors work with inside duals and inward facing valve stems?
PressurePro™ saves you the trouble of trying to reach the inside tires to check pressure.
The system monitors tire pressure constantly, alerting when pressure is low. No need to manually check tire pressures as frequently as you did before you installed PressurePro™!
Do I need to re-balance my tires when using a Sensor?
The 2/3 oz. Sensors Monitoring large tires (RV/Truck) seldom necessitate a tire re-balance. Smaller tires may require adding a 2/3 oz. stick-on weight opposite the valve stem.
What should I do if a Sensor is lost or damaged?
Replacement Sensors are available by contacting us at L&S Safety Solutions LLC (800-521-6820).
Note that Sensors do not come off by themselves; the centrifugal force, due to the tire rotation, forces the Sensors onto the valve stem and they will not come off while moving down the road if they are screwed on properly.
Is theft a problem?
PressurePro™ alerts when a Sensor is removed from the system, but as with anything, if it is installed, it can be uninstalled.
However, our experience indicates that theft has not been a significant problem; after all, the black, composite-material Sensor (not a pretty stainless steel cap) which replaces the valve stem cap, is quite small and inconspicuous!
However, Sensor Lock Nut Kits are available (see Accessories). The lock nut goes on the valve stem first, then the Sensor. A provided key-chain size wrench tightens the Sensor so as to "jam" the lock nut against the brass Sensor bottom, making it extremely difficult to remove without the wrench.
My Sensor was blown off in a blowout - no alert given - Why?
Instant tire failure is rare in comparison to the more common failure caused by gradual tire deflation. It is possible, during an instantaneous blowout, to have the Sensor blown off the tire before it has had a chance to send a signal to the Monitor. PressurePro™ is not designed for this type of tire failure.
Tire failure is often referred to as a "blow-out", when in fact, it is due to low tire pressure, resulting in an overheating of the tire side walls to the point of disintegration.
PressurePro™ will, however, alert of a low-pressure tire, thereby averting the eventual severe tire pressure loss resulting in what most people think is a blowout.
Why doesn't my Monitor turn on?
Make sure the lighter receptacle has power. Some vehicles only have power when the vehicle is running.
Check that the power cord is plugged in securely to the lighter receptacle on the Monitor. If the cigarette receptacle is always "hot", be sure all connections are secure.
A red LED light on the plug is lit when cord is powered. Check fuse located in the lighter plug-in end of the cord by unscrewing the black ring (at the silver tip) of the plug.
Replace only with a 2 Amp fast-blow fuse. Check the vehicle fuse controlling the power source.
What is the cold running reference pressure?
PressurePro™ Sensors automatically access the pressure in a tire when screwed onto the valve stems.
Removing the Sensor from the valve stem for 60 seconds will delete the old reference cold running pressure and allow the Sensor to accept a new cold running reference pressure when screwed back on.
It is advised to install the Sensors in the early morning when temperatures are cooler, so as not to cause spurious alerts during the cooler evenings. For example, if one is travelling during the middle of the day and decides to stop to check the tire pressures with a gauge, the working pressure of the warm tires may be 15 psi higher than the early morning cold running pressure.
PressurePro™ will "reset" to this new running pressure (which is higher than it should be). This may cause a false alert when cooler night temperatures occur, or when going up in the mountains where it is cooler.
To correct this, unplug the Monitor to turn off the alarm if it is alerting at night, and the next morning, take each Sensor off, wait one minute, and put them back on. They will again reset to a new, lower cold running reference (baseline) pressure. |
