Original Equipment Bluetooth Tire Pressure Monitoring System (TPMS)
A Global Solution for Tire Pressure Monitoring Systems
Riding on Air
Properly inflated tires involve more than inflating them to the
manufacturer’s recommended level. A few situations can cause
problems for drivers.
To start with, the manufacturer’s recommended air pressure is a
“cold” pressure. Determined by measuring tire pressure after the
vehicle has not been moving for more than one hour, this pressure
defines the load carrying capability of the tire and it is expected
to rise while driving. When they are hot from driving, tire
pressure measurements should not be adjusted downward to estimate
the cold inflation pressure even though most tires will normally
increase about 3-5 pounds-per-square-inch (psi) from driving.
Tire pressure gages commonly measure the difference between the
outside ambient pressure and the internal pressure of the tire
(known as gage pressure). However, tire pressure is affected by
changes in altitude. For example, a car with proper cold inflation
pressure in a high altitude location, such as Flagstaff, Arizona
will be under-inflated when it is driving in a lower altitude
location, such as Phoenix, Arizona by about 3 psi. Similarly, a
tire with proper cold inflation pressure in Phoenix will be
over-inflated by about 3 psi when it is driven in Flagstaff.
Seasonal temperature changes are also a factor for proper tire
pressure. Even if a tire does not lose air pressure during an
extended non-operating period (see Safety Considerations), a cold
inflation pressure set in the summer, say when it is 90°F degrees,
will be about 16% lower on a 0°F winter morning.
Without TPMS, drivers that don’t check their tires often or for
specific situations risk driving with improperly inflated tires.

TIPS FOR USING
1, When you see your TPMS dashboard light come on, you don’t need
to pull over immediately. You can wait for a safe break in traffic
before you pull over to inspect your tires.
2, You should still check the pressure of each tire manually if
you’re planning on taking a long trip or after returning from a
long trip. Long use – especially in very cold and very warm
climates – can change your tires’ pressures enough to affect their
3, Make it a habit to check your tires’ pressures at the beginning
of every new season.
