The Tuson TPMS monitors the following two tire pressure alerts:
• High Pressure – indicates tire pressure has risen 50% or more above the standard tire pressure
value set by the user.
• Low Pressure – indicates tire pressure has fallen 20% or more below the standard tire pressure
value set by the user.
Based on the general tire pressure inflation guideline and the system’s pressure alert parameters, you can
determine the standard tire pressure value to set for each set of tires using the following formula:
Type of Tire
Recommended
Tire Pressure
Low Pressure
Warning
Standard Tire
Pressure Value
High Pressure
Warning
Trailer Tire
80 psi (MAX)
80*0.8= 64 psi
80 psi
80*1.5= 120 psi
Passenger Vehicle Tire
32 psi
32*0.8= 25.6 psi
32 psi
32*1.5= 48 psi
<IMPORTANT 7>
The standard tire pressure value is the "cold" inflation pressure that the tire is designed to hold. It is also
important to remember that the vehicle/trailer's recommended tire inflation pressure is always to be
measured and set when the tire is "cold". Cold conditions are defined as early in the morning before the
day's ambient temperature, sun's radiant heat or the heat generated while driving causes the tire pressure
to increase.
