The Falken website shows the sidewall ply number. I had 285/75-16 Rocky Mountain ATS and I could have sworn they were 3 ply sidewalls but the website shows them as only 2 ply. I know for a fact that the sidewalls were very thick...I pinched them before having them mounted. The tires are also very heavy for their size due to this as well.

My favorite quote from the press release.. sad but true: "Chrysler claims its products, especially the Jeeps, can handle all sorts of terrible conditions, churning through muddy swamps, climbing mountains, and crossing rivers. Turns out they cannot even handle a car wash."
