Took lots of online delving to find the difference.That's the interesting part....they have (to the eye) exactly the same pattern, and the same load rating (which I think is as close to get to measuring the strength of the side walls). I'm VERY happy with mine, just confused!
the stronger sidewall is to make them more suitable to track and field use, the SUV theoretical useage, in that there is a stronger sidewall rubber part, to withstand rut and stone potential damage.
The tread is said to be more of a V cut rather than an I slit.
The load rating is related to the tyre carcase cord strength not the rubber thickness.
