I have a 2004 Cougar 278EFS 5th wheel. Loaded (gross?) weight around 8100 lbs. I bought the unit last fall. The tires that came on it are 205 75R 15 load range D. Some oddball brand which I don't recall at the moment. I was reading a forum post that Sailun tires are the go to brand. So I went to their web site but did not find a trailer tire in that size. Got me thinking that maybe my installed tired are not the right ones. Haven't found the manufacturers recommended size. Can anyone help me here?

Thanks, Friz
