Did the first tire rotation at 4,981 miles.
Note the red arrows.
That's where the tread is not as deep, and has changed the tire pattern.
The tire on the right (came from the right-rear) is showing 1/4" tread depth.
The tire on the left (came from the left-front) is showing just shy of 3/16" tread depth.
Hmmmm. I like the way the tread pattern wears.
Might explain why I've been doing a bit better lately on the track.
Course, now that I rotated em....
