When I bought my Michelin P4S there were not N0 rated. I have no problem with them. Thx for the link
explaining the N* rating, but yeah it was kind of vague. So the P0's that I took off my car were very noisy
compared to the MP4S. Not sure how they rate noise to get the N* rating. I hear that the next gen of P0's
are much quieter than the previous generation.

 

Not sure what of any changes they might make for N spec Porsche, I note the 4s puts a 911 at the top of their advert, suggesting working together rather than satisfying Porsche afterwards. Porsche and Michelin are obviously close. Closer I suspect then Pirelli and Porsche ?

Only difference you will feel regarding N and non-N is tires is on the track, where you might be able to shave off a few hundreds of a seconds.

 

Here's a performance tire review

 

The newest Pzero's have pretty decent performance, I'd say about as much as the old Pilot Super Sports. The problem is that they are stiff and a bit on the louder side but by no means trash.. You haven't experienced trash tires until you've driven on the Pzero Nero's, Conti DWS, Falken F452's, or the Hankook V12's LOL. Now those are trash..

I can't wait to try these new PS4S. I'm a huge michelin fan and normally any transition to michelin tires are that they ride better, have less noise, last longer, best in the wet, tire is made evenly, and the best yet ARE LIGHTEST IN THEIR CLASS!!

 

Slightly off topic, when do you guys feel that the tpms need to be replaced. Read somewhere that it is after 6 years

 

when it fails...

 

Correct answer. Ding ding ding.

 

Good question. Thanks for asking.

Really? Let's say your wheels are 8 years old. I'd hate for a TPMS to go out a few day after having new tires mounted, only to have to return, pay again for road force balancing, and another chance to damage a wheel. I'd rather be more proactive, and replace prior to failure, but not too soon to waste $. Tough call.

 

From my experience it isn't a normal wear item. Some fail, some don't. I sure would hate to replace them proactively only to have one of the replacements fail prematurely and be in the same predicament.

 

Your review is spot on! The biggest difference is in ride quality, along with everything else. Grip in the wet and dry is way better as well as tire degradation.

 

 

True!

Reservoir runs soon, if this damned weather ever changes...

 

good read...thanks!

 

this latest gen of pirelli pzero and conti xcntt are more much relevant competitors to mpss/4s than ever before - the gap was HUGE before, now within shouting distance, which is quite a big deal actually

mpss to mp4s is more of a sideways move imho - better wet grip supple ride no better in dry really
