Q: Is the Tyredog a 'Direct' or 'Indirect' system?
A: Direct TPMS.

Q: How does receiver get IDs from sensors?
A: The sensors and monitors are matched with a 7 character alpha-numeric ID.  

Q: Can sensors be stolen?
A: Sensors need special tool to remove . The sensors only work with the original matched receiver.  Attempting to use a sensor with an unmatched receiver will not work.

Q: How robust are these sensors?
A: Tyredog sensors are tested against water, intense vibration, impact, long-term pressure & temperature cycling. They are also exposed to harsh chemicals commonly found on the roads just to make sure that they meet the demanding automotive requirements.

Q: What is the sensor's output power?
A: Most of my documentation mentions < 10mW EIRP which roughly translates to about 10dBm.

Q: What is the sensor's operating temperature range?
A: From sensor to receiver, they can operate between -30° to 145°C.

Q: Can the system detect the sensor correctly after tire rotation after service?
A: For this question / answer you should reference that this is the internal version of the Tyredog TD-1000A-I.  This would not apply to the external models as you would just unscrew the sensors, rotate the tires, and screw the sensors back on.  

Q: Is it possible for sensors to interfere with one another?
A: Each sensor has it's own ID matched with the supplied monitor.  It is VERY VERY hard to interfere with other sensors.

Q: How precise are these sensors?
A: I find that the sensors measure everything in PSI and internally they convert to other units (like kPa or Bar), while the packaging states 0.5 PSI accuracy, I have found the manual say +/- 1PSI on the product specifications page.  I thought you should be aware, just in case questions arise about it.  

Q: How easy is it to install Tyredog TPMS?
A: (External Product) Zero cost for labor as there is no need for hard-wiring whatsoever. (Internal Product) Sensor should be installed by the professional.

Q: How frequent does it measure temperature & pressure?
A: Sensors receive data once every 5 seconds . Pressure or temperature changes make the sensors transmit information.

Safety

• Many major fatal car accidents (according to statistics) on highways are attributed to improperly inflated tires.
• Over 80% of tire pressure loss occurs gradually – many times without the driver noticing.
• Drivers check tire pressures once a month and do not view properly inflated tires as a critical component of the automobile operations.
• As a tire increases in temperature the construction of the tire weakens and the possibility of side wall failure increases
• When a tire is over inflated, the tire treads do not sit squarely on the pavement causing decreases in traction and high possibilities of hydroplaning on wet roads.

Tire Life Expectancy

• Optimal tire pressures helps to ensure that the tire wears evenly across the treads.
• For every 25% excess in tire pressure, the tire life expectancy may decrease up to 20%.
• In under inflated tires, a reduction of 25% in tire pressure, results in tire life expectancy being reduced by ~30%
• Tire temperature increases cause the tire hardness to weaken, chances for the tire deformation will increase, subsequently decreasing a tire’s life expectancy

Fuel Efficiency

• For every 3 PSI loss from optimal tire pressure, fuel consumption increases by 1%~2%

Helps keep your tires in optimal pressure helping to deliver maximum safety with maximum fuel efficiency.
