- Who heads up EnTire Solutions, LLC?
Laurent Crosnier is the CEO of EnTire
Solutions, LLC.
- What are the types of tire pressure
monitoring systems?
Direct and indirect tire pressure monitoring
systems are available.
- What are the differences between
direct and indirect tire pressure monitoring
systems?
Direct TPM systems directly measure the
tire temperature and pressure via a sensor
that is installed on the wheel. Indirect
TPM systems indirectly measure air pressure.
The most prevalent indirect TPM systems
in use today utilize anti-lock braking
systems (ABS) to measure the difference
in the rotational speed of the four wheels.
A wheel that is rotating faster than the
others infers that wheel has lower pressure
than the other wheels.
- What are the costs to a vehicle
manufacturer to implement a TPM system?
According to NHTSA, additional vehicle
costs depending on the type of system
implemented would range from $49 to $69
a vehicle.
- Do direct tire pressure monitoring
systems with a tire location display (auto-location
capable) need to be recalibrated when
tires are changed or rotated?
Most direct tire pressure monitoring systems
on the market today need to be recalibrated
when tires are changed or rotated. EnTire
Solution Enhanced systems, however, with
its auto-learn capabilities do not require
a handheld tool to reconfigure the system
when tires are rotated or when a new sensor(s)
is added to the vehicle.
- What is
placard pressure?
The placard pressure is the vehicle manufacturer's
recommended cold inflation pressure. This
information can be found in the owner's
manual and often on a placard (permanent
label information) located in the
vehicle's doorjamb, inside the fuel hatch,
or on the glove compartment door.
- Who is NHTSA?
The National Highway Traffic Safety Administration
is a U.S. government agency whose mission
is to save lives, prevent injuries and
reduce vehicle related crashes. For further
information, please visit www.nhtsa.dot.gov
- What is FMVSS 138?
Federal Motor Vehcile Safety System 138
is the regulatory portion of the U.S.
TREAD Act that regulates tire pressure
monitoring (TPM) systems in the U.S.
- What is
false alarm?
A false alarm can occur when the system
fails to notify the driver when there
is a low tire pressure or a system malfunction,
but also a false alarm can occur when
the system notifies the driver of a low
tire pressure or a TPM malfunction when,
in fact, the tire pressures are correct
and the system is functioning properly.
- What is
run flat tire management?
Run-flat, continued mobility and zero
pressure tires are able to be driven for
a specified time (mileage) at a specific
speed in run-flat mode before they must
be changed. Run-flat tire management is
a software algorithm that measures tire
pressure, temperature and tracks speed
and miles driven in run-flat mode and
keeps the driver aware of how much longer
a run-flat tire can be used prior to damaging
the tire.
- What is
same axle pressure imbalance?
Same axle pressure imbalance is a software
algorithm that identifies significant
air pressure differences between tires
on the same axle, even if both tires are
above the under inflation threshold, and
informs the driver accordingly. Significant
pressure differences between tires on
the same axle can lead the vehicle to
"pull" in one direction.
- What is
pressure unsuitable for speed?
At a given air pressure, tires can carry
a load only up to a certain speed. This
software algorithm measures and notifies
the driver when their tire air pressure
is not suitable or too low to travel at
their current speed, allowing the driver
to make appropriate adjustments to speed
and/or tire air pressure.
- What is
static load management?
Static load management is a software algorithm
that compares the air pressure and the
load on the tires. The algorithm informs
the driver if the air pressure is not
sufficient for the load on the tires,
thereby avoiding, if air pressure is corrected
by the driver, premature wear of the tires.
- What is
auto location?
Auto-location is the ability of the TPM
system to automatically determine the
location of each active sensor. Enhanced,
direct TPM systems are able to auto-locate
and to inform the driver which tire is
under inflated.
