Tire pressure for Michelin Agilis while towing?

[macsinbragg]

I am taking off the stock tires and putting on Michelin Agilis cross climate from Costco with a weight rating of 123. I am towing with a 2021 lariat powerboost.

I am towing a 25' Stratus TT with a tongue weight around 600lbs.

Wondering what tire pressure I should have those tires at while towing?

Chalk test them while loaded. There are too many variables to give you a definite answer.
