for me nothing changed except for the tires, running very close to stock alignment specs, with a little more camber in the front just due to lowering of the swifts. Im on swifts and konis btw, which handles better than many budget coils in my opinion...I just do not see the value in this tire for its performance level, that is my overall point.

I had the RS3's and then the PSS's and I can tell in the sidewall flex and the responsiveness in the steering feedback that the PSS's are a better tire. The RS3's where nice once you felt the car slide it it's rut like hooking on to a rail, then it was point n' shoot. The pss there was very minimal feedback and instant response in the turn.

only other tires I acutally ran in that category on this car were the s-04, which I was going to buy, but between the forum and the reviews, I went with the PSS. If you do not care about tread life, re-11's no doubt. I do not know if they make them in our size, but my buddy has star specs on his rx8, and those were fantastic. I can tell you I would also be satified with KDW's in comparision to the PSS(ran them on the 350z), regardless of what reviews say, it is a sticky tire and it performs well, a guy at work runs auto cross with it and does quite well on it, enough so he is buying another set.

RE'11s are a great choice as well.

so you're saying that your car ran great on S04's, but runs like crap with PSS?

if so, i can understand your frustration. the S04's are good tires, i know from experience. PSS, ive not driven on them yet so i dont know.

Just tossing this out there. But then again, Michelin probably paid off tire rack :rolleyes:

yah, tirerack seems to luv the pss... so that's kinda why i was scratching my head.

.....where's joe? He crash with his pss? :icon14:

:icon18:

Even engineers at Ferrari got fooled lol

Monsters of Grip: Nine Summer-Performance Tires Tested Comparison Tests - Page 10 - Car and Driver

Perhaps the slightly rounder/fatter sidewall doesn't fit your driving style or what you deem the most important. I think the stiffer sidewall tires can give the illusion of faster cornering, and that may be true on a perfectly flat surface, but that's not necessarily true on uneven street surface?

And "very close to stock" alignment....a hair bit amount of toe change can hugely affect handling (I thought lowering also affect toe?).

I also wonder if stiffer spring magnifies the softer sidewall too (more compression force acting on the tire hence more sidewall flex maybe?)

Update. I've had the tires on a week now and hands down they are better than the stock advans that come on the NISMO. I have no problem with feedback, steering sensitivity, or response. They are far sticker than the stockers for sure. I don't notice any rolling of the sidewall on aggressive turns either. They are also much quieter, smoother, and absorb a little more of the road bumps compared to the advans. Overall I'm happy with them. I think in order for me to be 100% happy with the traction of the car I will have to get a true LSD to replace the crap VLSD that comes on the car.

RE-11's are a good option and honestly what I was going to go for but the front tires are not rated (with regard to weight) for the NISMO. I tried multiple tire places and they all said they wouldn't be able to mount them for me. Why Nissan rated the front of the NISMO heavier than the regular 370z I'll never know. I could have just lied and said I had a regular 370z that I added a body kit to but wasn't worth the hassle since I could get the PSS

Will be hitting up the next auto-x in 2 weeks and will report back then.

Its called business, if Michelin and Ferrari make a business deal, of course its the best tire... illusion on not, I cannot liked going around a corner and having sidewall flex, they do flex, maybe its the 40 series sidewall is too high, but again I will reiterate, the bridgestones did not have this issue. The grip is fine, the ride is fine, the steering response is not good, and they are not as stable as the stones, that's just fact...haven't driven on the advans, so I do not know. If i go into a corner hard at speed, and turn it, I can feel the sidewalls flexing, I am not trying to insult anyone, maybe some people do not know what that feels like or are ignorant to it...again I do not know, this is my second set by the way, had the first set swapped out after 500 miles... they only thing different on my alignment is front camber is slightly more than factory due to being lowered on swifts, all else is within in factory spec, like I said the only thing that changed on my car was the tires, suspension and alignment stayed the same, the toe will impact the highwa stability at large, thats why they run a slight toe in from the factory. IMO it is just not how this expensive of a tire should perform.

Toe affects turn, not just str8 line, to clarify. Best of luck with your tires.

Not debating your sidewall flex experience however, just trying to point out things that can affect the handling. I think if I am to go with pss in the future, I'll just go with stock size instead of the popular 265 up front. Keeping it slightly stretched may help a bit.

Of course it does...but toe in does not help cornering or turn in, toe out will,thus if I said I am not running close to stock specs, someone would have been all over me blaming that... but they specifically toe in for highway stability. I went 265f and 295r originally and got rid of those promptly for stock sizes, which are better by far. If I were to do it again, knowing what I know about the pss I would use nismo rear at 285/35 and go 255/35 in the front, but next time it will be the s-04 or re-11.

I had these on my Z for a year, went to 3 track days and they performed like an extreme performace tire. The reasons they are so costly IMO is because 1) they are Michelins 2) they are more comfortable and quieter that any other summer tire that performs as well as this one (if there is one). 3) they are lighter that pretty much any tire.

PSS may not be the best bang for the buck for sure. But nothing like these as far as ultimate grip (for a max performance summer tire).
You can argue that there are some tires that are not too far behind and cost like 25% less but like I said they are behind.
