We have a 30 ft. 2003 Itasca Class C and I have all Hankook tires. No compelling reason other than that's what my tire shop suggested and put on. Also had them on my last car. No problems at all. It's not been proven to me that the most expensive or best known brands are significantly better than something like Hankook so I tend to shop for price somewhat. That's important with a 6 tired vehicle. I've really never had problems with tires throughout my 60 years of driving. Maybe more important to make sure the tires are heavy duty to handle heavy loads and to watch for under inflation and replace at 5-7 years no matter the looks.
