I have commented on this before over the years and here it is again. I bought 215/85R-16 and the dealer did not want to put them on my stock 16" narrow rims. Was concerned about the tire 'rolling off' and said the minimum wheel width was 5" or 6". I forget now.
Went to a second dealer, same story and mentioned the lack of a safety bead and that if he installed them, which he did not want to do, he could not give me the warranty.
Ironically a truck I built for a friend had those same radial tires installed on stock rims a few years earlier by the first dealer above. And a lot of 'bolters have used them as well. Maybe things have changed.
As for me I bought a set of 6:50-16 Firestone bias-ply. Do I like them? I love them. Perhaps not as nice as radials but they are smooth, do not bump when cold and handle really nice. They do have the bias habit of following cracks though. I do not drive faster than 45 MPH and log about 2000 miles per year.
