Somewhat misleading since wheel widths are not shown, and those make a big difference in section width measurements. I can promise you that a 275/35-19 Michelin PSS is definitely wider than a 265/35-19 Continental DW when both are mounted on the same 9.5" wheel (recently evaluated this when buying PSS').
Here's one of my examples (I have many of these I've evaluated) -- this is a 245/40-18 BFG Rival, both tires shown are identical.
Guess the difference.
