Well said 2roll.
https://www.rvtiresafety.net/search/label/Trailer%20inflation Use Tireman9 tire blog. Its a heck of a lot of reading but he explains why we use max pressures for a tire on a trailer vs a motorhome/truck/suv/etc. Look through all the clickies on the left hand side of his blog. Lots of reading when the snow flies.
Tireman9 (Roger Marble) is on other rv websites and was a member on this web but he has advertising in his sig. Against the rules :R
He has pages and pages on this subject. Some time it would be nice if they were all categorized ....like tires we use on trailers under one heading.
