Eight years ago using Michelin’s RV tire maintenance manual (Google it) I weighed my MH and established 80# as the proper tire pressure for my 19.5” tires.
When I first took my MH to a truck service center they automatically increased the pressure to 100#. When I questioned them they knew nothing about the relationship between RV corner weight & tire pressure. I just got 6 new 19.5" tires for my Itasca MH from a large tire service dealer and they automatically put 100# in each tire. Again when I questioned them they knew nothing about the relationship between weight & tire pressure.
Remember the more pressure the rougher the ride. My old tires were 10 years old and had over 50,000 miles on them but had worn evenly and still appeared in good condition.
