For the TST system, and it really doesn’t matter for any of them, the default temp setting is 158 degrees. This is based on studies by Michelin that determined that number to be where the tire begins to fail. I just listened to an interview of Roger Marble, a retired tire engineer who when asked about temperature settings for TPMS systems, said it is worthless because the places in the tires where heat matters can’t be measured by these sensors attached to valve stems. So, I just leave the 158 degree setting alone and just watch the pressures. I set the low pressure to 100 psi because below that the weight capacity begins to be lower than I want, and the high pressure I set so I don’t get nuisance alarms, maybe 150 psi.
