I am a new member but have been lurking for about 6 months so.....at the risk of being kicked out, I have a tire question. I purchased a new to me 2009 31 foot Keystone Hornet TT in September 2013...
I did not check the Carlisle, but E series, usually want 80 psi to get to 2830 load limit. Many times the rims are only rated for 75 psi. It is usually stamped on the rim somewhere, maybe inside the tire. Just a suggestion.
I found this when I went to E rated tires. Just my .02
EDIT: I guess I should have finished Fast Eagles post. Sorry Fast Eagle!!!!
