My 2 cents worth... I have the Dunlop 8080e's and I too got all the conflicting info. The car came from the dealer with 38/42. This was a little too soft for my liking and after consulting with them, I raised the pressures to 42/45. This seems to be a good compromise as the car handles well at high speeds and corners well too. The ride stiffens up a little and this is great in my opinion. This IS a sports car!
I ran the tires for a week at 45/48 and while the steering feel gets a little lighter, I felt I didn't need that harsh of a ride. True, the traction control engaged with hard acceleration or agressive cornering. Everyone I talked to says keep them above 40 all around. I agree. Watch for uneven wear, especially on the front tires. If you corner agressively, increase the pressures into the mid to upper 40's. The Michelins should run the same way. The car manual does not know what brand of tires (ie the rating)that will be put on the car and most likely has a wide safety margin built in. The door sticker is much more accurate. The local Dunlop dealer said to run them as high as you can stand up to the maximum if doing serious performance driving, however said to back them off at least a few pounds for everyday driving. They do a lot of high performance cars and seemed to know exactly what the answer was.
Has anyone ever asked this question at the driving school?
