The Alba Belt Temp Gage is a much nicer unit and it is easy to read. You can see on the Alba gage running in the yellow section will increase belt wear, I like to stay below 180. My stock Teryx would run a bit over 200 after 10 miles of deep sand and mostly WOT. Large tires will increase the belt temp and a gage is necessary to avoid belt failure. Nate has way more experience especially with large tires and can add or correct any of the above info.
