browsing for tires online today, and noticed there are 3 types of MPSC's available:

(for GT2/3 stock front sizes 235's)

there's the "N0" for Porsche

there's non "N0" (presumably for other makes)

and there's a "N1" for Porsche and highlighted as a NEW product

but the specs look all the same. anyone know the diff?

there must be SOME kind of difference, because HP Lieb (Ruf test driver) specifically said they match "N0" rears with NON "N0" fronts for their RT12 in the Sport Auto Nurburgring test.

i'm sure i would not notice a diff, but any ideas?

and what's with the NEW "N1" tire?

TIA!

Different compound compared to the N0. N0 should be better on wet roads but worse on a dry track compared to the N1. I have no own experience with the N1 yet but a friend did a back to back test at the Spa-Francorchamps circuit a couple of weeks ago: 2x 997 GT3 MKII, one car equipped with the N0, the other one with N1. It was a sunny day (20°C) and the track was dry. After my friend (amateur racer) gained the impression that the N1 rubber sticked better he asked a Pro (Ch. Menzel) to drive both cars. He confirmed my friend's impressions.

many thanks for the info.

seems like the N1 is definite choice for a track only car, while the N0's are more suited for mixed duty cars (as most GT3's probably are).

The Ruf choice might be as simple as wanting the 265's on the front.

doesn't seem to be the case. the Sport Auto car ran GT2 sizes (235 19's in front). my car has same size on, for which HP specified the non- N0's...

I think a good upgrade for all the 997 cars would be the 245/35 and 325/30 N1 tires.
