I would like to see DOT data showing any type, make, or style of tire is superior to any other.
If someone can show DOT failures rates per miles driven, that would end a lot of hear say, bias and anecdotal information that permeates this issue.
As I mentioned, like many things in life, the choice of tires is based on a person's personal comfort level. It is certain the RV industry is going to continue to use the tire they have always used.
The reason I picked 2012, is because that is when I started to notice a lot of tire discussions but precious little government agency facts to back them up.
