This points to the need to compare RR values using the same test.
...it's actually worse than that; the "...Range of all tires used for this example: ISO = 1.13*SAE to 1.22*SAE" ...the 18% value (1.1787(x)-number) was just the mean value, however the correlation coefficient of R-squared = 0.9972 is very good.

...but, your summary is 100% correct. Do we compare small apples or BIG apples to those SMALL- and big-oranges?!?!
