Maxxis chart doesn’t make a whole lot of sense when matched with all of the pros pictured in the following pages. Almost all you can zoom in and see the Aspen is the tire of choice, but there are a few Rekon Races hiding in there and no one runs Ikons any more. If the 2,3,4 in rolling resistance were accurate that would not be the case.
Then the Rekon Race Semi Slick pattern is a 2 but the Minion SS pattern is a 4, which is also the same as the Aggressor and Disector? Very odd.
Only thing I truly agree with that chart on is the Ardent having a 2 for control, that tire has needed to go for so long. Who would take its complete lack of grip until the cornering knobs when the Rekon exists?
