"Highways" article about all RV tires

[scattershot]

I read that article, and found it less than helpful. For example, on trailers, load range C,D, and E were most likely to fail. What else would you use on a trailer, for crying out loud? I'm sure they had advertisers to consider, but to be useful, I think they should have specified brands that were more likely to fail, or done a more indepth analysis.
