When you fill a tire with air, this becomes your base pressure at that ambient temperature when the tire is cool and before use.  If the pressure goes up you can calculate the temperature from the pressure rise, excluding tires that have a leak.  You will be able to determine leakers by a gradual loss in pressure with a tire management system (like enTIRE) that can track pressure changes over time OR a sudden loss of pressure via PressurePro readings.

It is inherently very complicated when measuring temperature.  What temperature are you measuring?  Do you measure the temperature of the carcass, or if so, where in the carcass do you measure – on the bead where it absorbs heat from the brakes and wheel or on the tread where most flexing occurs?  Do you measure the air inside the tire which would involve laminar flow analysis?  A mistake made by many people is to assume that the air inside a tire is homogenous but it’s not.  Simple fluid dynamics tell us this but it seems to seldom be considered.  We find little agreement on where to measure and what the measurement means.

Heat surveys are done to understand operations at a site.  It’s often done by the Tire Company that provides tires and maintains them.  One will want to know the following: are there leakers, or has the tire gone flat, or is there excessive pressure building.  We take the practical approach in regard to pressures.  Firstly if they are filled to the correct pressure when cold, then that is the correct pressure. Pressure may increase temporarily due to speed, distance, etc but pressure and temperature will always come back down to the cold pressure or below when the tire cools.   If ever it is necessary to take the sensor off while the tire is hot, the correct procedure is to wait till the tire cools, unscrew the Sensor, wait 45 seconds, and screw the Sensor back on.  It has now used the correct cold pressure as the SET point to trigger from.

“Correct” method to inflate a tire initially is to inflate it & leave it sit for 24 hours, then recheck it and inflate/deflate as required.  The tire will swell under initial inflation.  As a rule of thumb, a larger 22.5” tire for trucks or RV’s normally takes 24 hours to return to ambient temperature and pressure after running.

If you need to check pressures in the field, when they are hot, you could use the temperature calculation to determine the cold pressure.  A recommendation is to take the pressures of the tires on the same axle or close by to compare and fill the suspect tire to that level (or bleed air out).  Check to see if they are similar in pressures or is one possibly leaking?  This is where a Tire Management System comes into play, recording the history of each tire’s pressure over time so a trend can be spotted.

We believe a majority of tire problems can be recognized with this common sense approach.  For the rest, having a monitored temperature system to compensate pressure at various parts of the tire, including all the electronics and batteries and communication issues would be hugely complex, expensive, and time consuming.  We see more and more fleets today questioning the value of so much information vs. cost of that information.

This is just one reason the PressurePro system excels.  PressurePro is easy to install, simple to use, it’s reliable and accurate. PressurePro and a good management system can save money and make tires last longer and perform better.  PressurePro is an excellent solution

Pressure increases in a tire due to temperature is dictated by gas laws as below. The gas laws are a set of empirical laws that describe the relationship between thermodynamic temperature (T), absolute pressure (P) and volume (V) of gases. They are a loose collection of rules developed between the late Renaissance and early 19th century.  Three early gas laws:

• Boyle’s law (1662, relating pressure and volume): P₁V₁ = P₂V₂
• Charles’ law (1787, relating volume and temperature): V₁ / T₁ = V₂ / T₂
• Gay-Lussac’s law (1809, relating temperature and pressure): P₁ / T₁ = P₂ / T₂

These were combined to form the combined gas law

There will always be the argument that exact temperature readings are needed but we believe, as are more and more experts, that as a practical matter this is not required.  PressurePro alerts to high pressures which allows the driver/maintenance person to take action.  We believe strongly in concentrating on evaluating and monitoring tire pressures and forming decisions based on the axle, type of tire, construction of tire (bias/radial) and such, which often are ignored.

Seven days a week, across the United States, more than 5 million gallons of fuel are wasted on a daily basis due to underinflated tires. At the current average price of about $3.00 per gallon of gasoline in the U.S., that’s a waste of $5.5 billion dollars a year that goes right into the pockets of the big oil companies. For example, the tires on waste haulers (or trash trucks) have an average life of only 2,000 to 6,000 miles. This creates a major unnecessary expense paid for by municipalities, tax payers, corporations, and shareholders. What a waste!

Underinflated tires impact more than profits and poor fuel economy. They are a major concern regarding the safety and efficiency of commercial drivers. A low-pressure tire will eventually overheat, causing travel delays, premature tire failure, and possibly a fire or significant vehicle damage.

PressurePro is the breakthrough wireless electronic tire pressure monitoring system which sends an audible alert warning of low tire pressure before driving becomes unsafe. This protects drivers, tires, and vehicles from unnecessary costly damage. PressurePro can be used on RVs and tows, trucks/trailers, ATVs, autos and commercial vehicles.

“Big oil should be afraid of us,” says Duane Sprague, CEO of TirePressureMonitor.com.
An expert in Geophysics and Mechanical Engineering, Duane has over 25 years of experience in engineering, sales and distribution behind the best tire pressure monitoring system on the road today. “We can save businesses, government, and people tons of time and money that are wasted by something as simple as maintaining proper tire pressure.”

Wickenburg, AZ USA, February 1, 2010: L&S Safety Solutions (“L&S”) announced today that they are attending the upcoming Waste Expo 2010 taking place May 3^rd through May 6^th at the Georgia World Congress Center in Atlanta, GA to showcase PressurePro tire pressure monitoring systems (“TPMS”).  This show is North America’s largest solid waste and recycling tradeshow and serves both private and public sectors. Advantage PressurePro, a worldwide leader in Tire Pressure Monitoring Systems and Technology, will also be in attendance with L&S, noting that the Expo is a great way to get a better understanding of the waste industry’s need for reliable and durable tire pressure monitoring.

With the constant stop-and-go brake-generated heat challenge of the waste industry’s on-road vehicles as well as the treacherous conditions of their daily off-road exposure, this industry is averaging a tire lifespan of less than 6,000 miles, obviously detrimental to a fleet’s profits. Fortunately, TPMS can help extend this average tire life.

With tire life being a top concern for waste fleets of all types and sizes, PressurePro is looking forward to further educating the market of the numerous benefits that tire pressure monitoring can offer. Interested fleets and drivers in attendance at Waste Expo can find additional information at Booth # 1763. Further information can also be found online at www.TirePressureMonitor.com.

PressurePro is a wireless electronic tire pressure monitoring system and is capable of monitoring and displaying current tire pressures on demand, whether stationary or moving. Low pressure is the leading cause of premature tire failure but PressurePro can provide early notice of potential problems. Knowing about a low-pressure tire ahead of time is paramount to averting a flat tire and a subsequent blow-out. Fixing a tire is less time consuming and less costly than buying a new one and/or repairing your bike!

Monitor: Check each tire’s air pressure by pressing a button, even while riding down the road. Can also alert you to low tire pressures; digital readout shows the problem tire location and current tire pressure. Be alerted of low pressure tires before driving becomes unsafe.

The 433.92 MHz FM Monitor can monitor up to 6 wheels and is weather resistant. The Monitor displays each tire’s pressure and can send an audible and visual alert if pressures drop. It automatically dims in low-light or dark conditions and then brightens in conditions of bright light. Includes integral built-in antenna and extended power cord. Pressure range is 10-199 psi. Velcro mounts included.

Monitor Dimensions: 3 3/4?W x 1 1/2?H x 3/4?D

Sensors: Uses standard PressurePro tire Sensors (order separately).

Sensors screw onto the valve stems of your bike’s tires, replacing the valve stem caps. The Sensors transmit a coded RF signal and can alert if pressure drops approximately 12% under the cold running pressure for each tire.

The Tire Industry Safety Council has estimated that 50-80% of the 500+ million tires being used in the USA are underinflated. Under-inflation is the major cause of over-heating and contributes to ply separation, sidewall/tread breakdowns, poor tread life, tire disintegration, premature tire failure, and decreased road safety. PressurePro also helps to increase useful tire life and to save fuel by informing the rider of tire under-inflation.

Additionally, the Department of Transportation estimates that over 37% of all tires in America are under inflated. Low tire pressure is the number one cause of tire failure and contributes to heat buildup, tire disintegration, ply separation and casing/sidewall breakdowns. Increase your average MPG by as much as 3.3% with properly inflated tires. Properly inflated tires last longer; be safer with properly inflated tires.

PressurePro can be used on most pneumatic tires and can also be used on RVs and tows, trucks/trailers, ATVs, autos and commercial vehicles—up to 64 wheels with drop and hook applications.
