2017 Track Day Tire Test

First (bad?) test of the AD08R and second of the 888R on tirereviews. And there lies the problem, the results are very different from experience, these two should perform a lot better in the dry. And the 888R did perform a lot better in Sport Auto UHP test, better than the Cup2! Also, the comment of the AD08R 'slow steering' sounds very out of place, as it is a very sharp steering tire!

I strongly suspect that in this test they made a typical 'beginners mistake', or made a misguided decision based on 'same conditions for all' and ran the AD08R and 888R on too high standard pressures. These two are, contrary to the other tires in this test which are track optimised sports tires, more of a road legalized semi slicks with reinforced sidewalls. As such, they should be ran approx. 0,5bar lower in pressure for them to grip in the dry. If not, they simply won't heat and hook up, and just slide over their hard shoulders.

Unfortunately Auto Bild did not write anything on the pressures used, but anyhow, results are inconsistent here as actually also TireRack has tested these tires against 'normal' sports tires and these semi's most definitely do better in the dry.

Anyhow, nice to see the aquaplaning results (water depth?) and the unsuspected good results in the wet for the Trofeo R. More data needed though.
