Inflation check pattern on shoulder/sidewall PS2
At the track a few weeks ago, the instructors mentioned to look at the tire sidewall/edge for a series of triangles. Apparently you can tell if your tire is over /under inflated by looking at the wear on the triangles.
My PS2's don't have these, but they do have a series of rectangles around the shoulder, with a diagonal line through them.
Anyone know if these are the equivalent of the triangles and how to read them.
