Interpretation of the tire tread under fender in SP

From reading the rules,it states the tire TREAD cannot stick out beyond the fender edge.It then goes on to determine how the tread part of the tire is defined.


"Wheel type and size is optional provided the tread fits within the stock fender configurations measured by a vertical
line dropped down from the fender lip, while the car is at rest on level ground, with the wheels pointing straight
ahead. The edge of the tread is defined as that point on the tire that intersects with a 45 degree angle drawn from a line
perpendicular to the centerline of the wheel. This shall be measurable by placing one edge against the wheel sidewall of
a template consisting of two straight edges having an included angle of 135 degrees."

This is the line in the passage I can't quite get a grasp of...

Not quite sure what all that means...

So,is it OK for the sidewall of the tire to stick beyond the lip of the fender as long as the tread is under?

Yes.
Here's my interpretation. Anything outside the green line is ok.
