Abstract

A tire pyrometer including a control box (12) and a tire probe (14), wherein the control box (12) includes a display panel (18) that can display up to twelve tire temperature readings at the same time. Display panel (18) can also display average temperatures for various temperature combinations of temperatures taken by tire probe (14).

Claims

1. A computerized pyrometer for measuring tire temperatures of a vehicle having four tires comprising:

a temperature probe used to measure an inside, center, and outside temperature of each of the four tires, and

a control box including electronic circuitry that receives the temperature readings from the temperature probe and displays a numerical value representative of the temperature readings,

the control box having a display panel that displays twelve temperature readings at the same time, the temperature readings corresponding to the inside temperature, center temperature, and outside temperature for each of the four tires.

2. The computerized pyrometer of claim 1, wherein the control box includes a plurality of memory buttons and electronic circuitry for storing in memory all the temperature readings simultaneously displayed on the display panel.

3. The computerized pyrometer of claim 1, wherein the control box includes a plurality of buttons and electronic circuitry for averaging various combinations of the temperature readings and displaying the combinations in the display panel.

4. The computerized pyrometer of claim 3, wherein such average combinations include left front average, right front average, left rear average, and right rear average.

5. The computerized pyrometer of claim 3, wherein such average combinations include front average and rear average.

6. The computerized pyrometer of claim 3, wherein such average combinations include left average and right average.

7. The computerized pyrometer of claim 3, wherein such average combination include cross averages for left rear, right front average and right rear, left front average.

8. A computerized pyrometer for measuring tire temperatures of a vehicle having four tires, comprising:

control box including electronic circuitry that receives temperature readings of the inside, center and outside temperatures of each of the four tires measured using a temperature probe and displays a numerical value representative of the temperature readings,

the control box having a display panel that displays twelve temperature readings at the same time, the temperature readings corresponding to the inside temperature, center temperature, and outside temperature for each of the four tires.

9. The computerized pyrometer of claim 8, wherein the control box includes a plurality of memory buttons and electronic circuitry for storing in memory all the temperature readings simultaneously displayed on the display panel.

10. The computerized pyrometer of claim 8, wherein the control box includes a plurality of buttons and electronic circuitry for averaging various combinations of the temperature readings and displaying the combinations in the display panel.

11. The computerized pyrometer of claim 10, wherein such average combinations include left front average, right front average, left rear average, and right rear average.

12. The computerized pyrometer of claim 10, wherein such average combinations include front average and rear average.

13. The computerized pyrometer of claim 10, wherein such average combinations include left average and right average.

14. The computerized pyrometer of claim 10, wherein such average combination include cross averages for left rear, right front average and right rear, left front average.
