I am also due to change out my g670 tires on a Monaco 40-footer. On all four corners I'm running within 10%-15% of load limits. I would like to move from the 275 80r to the 295 80r. Can I mount these wider tires on the same rim? Staying in load range H the 295 provide about 700 more pounds of load carrying capacity. I like having a little more breathing room in my normal carry weight to maximum capacity.
