Tires for Ruf RT12?
I'm about to get a set of spare tires for the RT12. Right now I've got the Continental VMAX on it, 235's in front and 325/30/19's in back, on the OZ's.
At this point, my choices are down to:
PS2's 345/30 in back or MPSC's 325/30 in back (easy to get the front tires in the original sizes with either tire).
Some questions for y'all:
1) What kind of mileage can I get out of the MPSC's?
I've got MPSC's on my GT3 and the insides grooves are totally gone after around 3,700miles/6000kms. But the car is driven on the track, whereas the Ruf won't be doing much track duty at all, if any. So assuming purely street miles, how long can I expect these to last?
2) Is it ok to use the PS2's even if they're not "N" rated for Porsche?
The PS2's in 345/30 are "C" rated for Viper. Will that make a real difference for street driving? The Ruf does a lot of high speed running, but not a whole lot of heavy cornering...
(BTW, i know the 345/30's are marginally larger in rolling diameter than the tires i've got now... but its about a 1.7% difference, which I believe is acceptable)
Thanks in advance!

Disclaimer: I loved PS2 on my 993 for the last 100K miles or so.
1. No-track, MPSC probably 6-8K. PS2 about 8K, maybe 10K. I think MPSC are overkill for street.
2. Yes, but I would check with Damon the Tire Rack guy.

I don't think you can go +2 in the rear (345) without going up in the front as well. You need to go 245/35 in the front with the 345s in the rear to keep PSM from acting up, at least that's my information.
regarding tire wear, I had PS2s on my TT and the rears lasted less than 10k miles without track time and went down to the cords on the inside. I since went with the RE50As and will never go back to PS2.
For the track I got Hoosiers which are way better than MPSC's.
