I agree with the test results, but lets face it, nobody except a pro driver is really going to be able to tell the difference.


I disagree.

If a tire has more grip, better feel, better braking limits, you will be faster. Will that non-pro be able to tell the difference between the two with just seat of the pants feedback? Probably not, that's experience. The only difference you will see is in lap time. They will be faster, they will have more confidence, but not necessarily know why.
