You'll want to set your max pressure alarm to 20-25% over the PSI rating of the tire which is stamped in the sidewall, set the low pressure alarm to 10% below the PSI rating of the tire, and for a temperature 158 degrees is considered to be the safe max for the tire.

You didn't mention the load range of your tire, but a 215/75R17.5 load range H tire like the # LHWL097 you had looked at is 123 PSI so if this matches your tires then you'd want to set the alarms at 150 PSI, 110 PSI, and 158 degrees.
