Tire Temperatures
Posted by Tim on July 26, 2006
A lot of people are using infrared thermometers to check tire and bearings these days and are concerned about what temps the tires should be after driving some distance. I know there’s a tremendous variability depending on inflation, speed, road temperature, ambient temperature, etc., but is there a temperature that indicates excessive stress or potential tire damage?
During the manufacturing process, tires are cured in mold typically at temperatures above 230 degrees F. Engineers working with tires in all types of applications from mining tires to racing tires usually get conserned when they see temperatures in the casing (measured with probes)at or above the curing temperature. If the internal components of the tire get to these temperatures, the components that have been knitted together at these temperatures may begin to come appart. The problem with infrared thermometers is that they measure temperature at the surface only.
