Expert Answers about Tire Pressure Gauges

• Troubleshooting A TireMinder Tire Pressure Gauge # TMG-AAA-Multi That's Only Reading 5 PSI
• It sounds like the TireMinder Tire Pressure Gauge # TMG-AAA-Multi is either not properly reading and needs to be reset, you aren't pressing it straight onto the valve for it to get an accurate reading, or the value is set at bar instead of psi. To reset it you can remove the batteries for a few minutes and then replace them. It'd also b worth checking the charge level of the batteries or just replace them with ones that you know are good. The button next to the display screen can be pressed...

• Explanation for Trailer Tire Tread that is Convex Rather Than Flat
• I consulted with our resident tire expert, and we're both at a loss. Heat build-up caused by over or under inflation, overloading the tire or failing to observe the speed rating of the tire (65mph in most cases) are the typical causes of premature tire failure. When you describe the tires as being 'rounded', I'm assuming that you mean that the tread portion of the tire is convex, rather than being flat so it makes full contact with the pavement. Over-inflation usually causes this, but...

• What Can Cause a Trailer Tire to Fail Prematurely
• Using the wrong tire pressure can cause the problems you described but it sounds like that's not your issue. I wouldn't blame it on tire scrubbing like you mentioned either. The other things to check is age (probably not case since it sounds like your tires are newer), weight capacity, and speed rating.

• Trailer Tire Wear on Outside and Inside of Tread Only After 600 Mile Trip
• Tire wear on the outside and inside tread only generally means that the tires were under inflated. Kenda tires are also rated for a maximum of 65 miles per hour so speeds above that likely exacerbated the issue. I don't think it was a weight issue because for weight to cause this problem the tires would have had to have been severely overloaded. What is the tire size and load range indicated on the tires you have? There should also be a maximum psi rating listed and the tires should be...

• Gauge in Firestone Level Command II Reads Same Pressure After Adding More Air to Air Bags
• It sounds like there is a leak or something mechanically wrong with the gauge. Leaks in an air system can be difficult to find. One way to find then is to rub connection points with soapy water and look for bubbles. A lot of times what happens is if an air line is not cut perfectly straight with a hose cutter like # AL10530, it could leak easily. If you cannot find leaks and the system seems to be holding pressure but the gauge does not move correctly then you can try connecting a different...

• Firestone Air Command Does Not Release Air Pressure or Increase Air Pressure
• I spoke with my contact about the problem you are having and he immediately knew what the issue probably is. He stated that most likely you have the air tubes at the back of the gauge switched so they are in the wrong places. That would account for the problems you are having. Looking at the diagram Figure C in the instructions linked for reference there should be a location labeled DEL and that line goes to the air springs. The other labeled SUP goes to the compressor. If this does not...

• Troubleshooting Roadmaster Invisibrake that Shows Zero Pressure
• Are you sure the pressure is being lost and not actually maxed out? If the air pressure of the InvisiBrake part # RM-8700 is set to the maximum the gauge will actually spin completely around the gauge and show zero. To confirm that the compressor is operating properly, pull out on the brake pressure adjustment knob and rotate it counterclockwise. The needle will move as you lower the pressure. Adjust to desired pressure setting.

• Trailer Tires Wear Out on the Center Tread on a Rally Wagon Trailer Towed Behind a Motorcycle
• First of all, the trailer tires that we carry are rated for a maximum of 65 miles per hour unless otherwise noted on the tire sidewall. Going faster than this will cause rapid heat build up in a trailer tire (which has a thicker sidewall) and can lead to failure. When tires wear out in the middle that means that they are over inflated. You can try taking out about 5 psi or so until you get even tread wear. If a tire is inflated to the max psi, it should not wear unevenly. You may want...

• Can Air Flow Either Direction Through Low Pressure Sensor of Air Lift II Compressor System
• The low pressure sensor valve on the # AL25592 can have air flowing through either side of it. It is not a one way valve. When you removed the air line that would have released all of the air pressure out of the system. Try inflating the bags with either the manual inflate valve or the compressor.

• Troubleshooting A Non-Working Fogatti Tankless Water Heater
• The Fogatti RV Tankless Water Heater # LSB64FR requires the following to properly function: 8-13" WC gas pressure (11"WC pressure preferred). 14.5-116 PSI water pressure (40-45 PSI preferred). 12VDC electrical power. First test your voltage using a multimeter like the Digital Multimeter # PT89ZR. If you're not receiving enough voltage you may be too far from the battery and need to increase the gauge of the wire. You should have 12AWG but may need to switch to 10AWG if your wire is travelling...

• Troubleshooting A Fogatti Tankless Water Heater That Turns On But Doesn't Heat Water
• It's a bit strange that you're not even getting an error code. Is there still water coming from the hot tap on your faucet or nothing? If nothing there's probably a shut off valve somewhere on the water line preventing flow and cause the unit to not kick on. If there is still water coming from the hot tap then you'll want to run through the requirements for proper unit operation. The Fogatti RV Tankless Water Heater # LSB64FR requires the following to properly function: 8-13" WC gas...

• Troubleshooting Roadmaster InvisiBrake Lack of Air Pressure
• I can certainly try and help you find out what the issue could be related to your Roadmaster InvisiBrake Supplemental Braking System # RM-8700 and its lack of air pressure. If it was working fine, the most likely cause is a loose hose, which would be something that would cause the air pressure not to build. Additionally, according to Roadmaster, this can happen if the pressure is set to maximum. If so, the needle will have rotated around the gauge and making it look like it is at zero,...

• Troubleshooting Tire Pressure Leakage on Yakima Rack and Roll Trailer Stored for 18-Months
• The tires on the Yakima Rack and Roll trailers # Y08106 and # Y08107 are indeed specified for inflation pressure of 40-psi. To lose about half that pressure after a year-and-a-half of storage is not at all surprising, but for the two tires that lost all of their pressure I suggest some further testing before you embark on your 2400-mile trip. You did the right thing by inflating all three tires to the specified 40-psi pressure so you can keep an eye on them for a few days. If they hold...

• Trailer Tire Inflation Pressure and Speed Ratings and How Do They Affect Tire Performance
• All trailer tires, regardless of brand, size or construction, should ALWAYS have a cold tire pressure as is listed on the tire sidewall. This maximum cold psi pressure is required for the tire to meet its weight rating. It is never appropriate to under- or over-inflate a trailer tire for any reason. There is no benefit to doing so and the incorrect pressure can lead to uneven tread wear, reduced capacity, excess heat and tire failure. Always start your travel day with your tires inflated...

• Troubleshooting Trailair Air Ride Pin Box Not Holding Air To Line on Shock Sticker
• The Trailair Flex Air 5th Wheel Pin Box - Lippert 1621 - 21,000 lbs # LC369535 will have an air bag pressure range between 20 and 120 psi. Lippert techs say that sticker is there to assist but is not always accurate due to the fact it is a sticker that can be slightly misplaced. If your air bag is within the 70-100 psi range then they said not to worry about the sticker. It is a reference point and not a perfect guide. I recommend using a pressure gauge to confirm the 70-100 psi as...

• Tire Pressure Rating for Pontoon Boat Trailer Tires
• Trailer tires typically blow out if they are not properly inflated. Trailer tires need to have the max tire pressure listed on the sidewall in them at all times otherwise they can fail due to reduced capacity and heat build up. Be sure you are not exceeding the speed rating for the tire or overloading it as well.

• Potential Causes for Excess Heat Build-Up in Hubs/Drum
• Properly-adjusted trailer drum brakes should apply enough drum pressure to put some noticeable drag on the hub as you rotate the wheel by hand. You should hear and feel drag but still be able to rotate the tire. Self-adjusting brakes require an initial manual setting, after which they will automatically TIGHTEN as needed but they will NOT automatically loosen if the initial setting was too tight. Odds are your one brake was simply set too tight at the start. You can use a brake spoon tool...

• Troubleshooting A Fogatti Tankless Water Heater That Wont Function
• First you'll want to ensure the the on/off switch (pictured below) on your Fogatti RV Tankless Water Heater # LSB64FR is in the "on" position. The next step would be to check your voltage using a multimeter like # PTW2992. If you're not receiving enough voltage you may be too far from the battery and need to increase the gauge of the wire. You should have 12AWG but may need to switch to 10AWG if your wire is travelling 60 feet. If your voltage is fine the it's time to check the gas. Fogatti...

• Understanding Pressure Rating and Temperature of Trailer Tires
• Irregardless of the ambient temperatures, we always recommend you fill the tires to the max psi listed on the sidewall while cold. This max psi rating will account for the psi increase as they warm. Unfortunately, there is not a standard psi/temperature in which a tire becomes unsafe to drive on as most of them have different ratings specified by the manufacturer. The pressure ratings set by the manufacturer takes into account many variables. If there is a max psi and temperature range...
