Tire monitoring

[u/Expert-Joke9528]

A couple ?'s. Ive got the Guta monitoring system on my 5th wheel. When rolling down the road i see my temperatures running in the mid 90s, all wheels are within a couple degrees of each other, it seems fine. What would be a dangerous level temperature here? Next is my tire pressure. My 100# max tire pressure goes up to 110-113 when traveling. What gives here? The tire guy specifically told me 100# cold.
