I've seen a lot of discussion about 17", 18" and 20" rims and LT tires, but haven't found anyone mention running heavier truck rims/tires. I used to have a slide-in camper that I used with my 2001 Dodge 2500HD Cummins. After having two LT truck tires blow on me (which is a lot of fun at highway speed with a camper on your back), I started reading in some of the truck camper forums about tires. Almost universally, they claimed that LT tires were inadequate for camper use, especially on SRW pickups. Their recommendation was going with a true truck tire on 19.5 rims, and most made reference to a company called Rickson Wheel Manufacturing (Rickson Wheel Manufacturing
) which made custom steel 19.5 rims to fit regular p/u trucks. You could also get truck tires through them, and they would do match mounting and balancing. I did quite a bit of research, and all references were positive. I ended up selling the camper ($$$ - daughter's wedding) and thought no more about it. Now that I have a new AS 27FB Classic, I'm revisiting the issue as an upgrade for my TV. Any info or thoughts out there?
