It would probably only ever make a difference in that situation because they are constantly recording data on the nurburgring trying to aim for consistency with variables and such. |
Many places made a big deal about it at one time but it has sort of dropped off the map since several government studies showed it is meaningless in a normal car. I am not going to bother to link any because I am perfectly aware there are probably an equal number saying that it is god's gift to tires.
What it is good for is a cheap and easy upsale for dealers and tire places or else it would be gone by now.
