If you ask the good folks here what they keep their tire pressure at for a comfortable ride or when driving under certain circumstances, that's one thing, but when you Ask a Specific question like the one YOU are asking, that is best answered by the "guy" who actually made the the "thing" then maybe it's best to go to the Manufacturer and ask, they have engineers that have worked on this their WHOLE life and are best suited to answer your question. Personally when I have a question, before I come on here I GOOGLE it. Unless you're just looking for good conversation, then you've come to the right place.
