There must be something wrong with me...No digging the Pilot super sports...
 

Ugh, just wanted to share my experiences so no one else blows 1200 bucks on tires and ends up as I have. After weeks of research, all fingers pointed at the PSS. After reading many threads here, I was convinced I needed to plus size, so I did. from stock rays sized to 265/35 F and 295/30 in the rear on stock rays(yes slightly smaller OD that's how I wanted it). I was running stock re50 in front and s-04 in the rear. These tires have little corner stability and are "mushy" the sidewalls roll and I feel no confidence in spirited driving. DO not get me wrong, the grip is FANTASTIC, but the car is "wobbling" on the sidewalls in hard corners, it is quite frustrating. I and going to attempt to work with Michelin and Tire Rack( I do not even know if the Michelin promise thing will work since I plus sized, trying to find out) and try them in the stock size in hopes of better cornering performance...oh well, my opinion is this, if you care about cornering performance, do not plus size on the stock rays with these, if I can get them swapped out for stock sizes,hopefully that will go away and I can join the oodles of happy PSS owners, or I will have to see if I can sell them used, I don't think my driving style can live with these. Sigh, ok vent over! :happydance:

Play with the tire pressure a little. When I had my Eclipse the recommended tire pressure was 32 front and 28 back. I ran 35 front and 32 back and was quite happy with the way the car handled.

Im at 40 psi now, do not really want to go any higher...

Higher? DUDE GO LOWER. 40 psi is too high. Id suggest mid to low 30s depending on weather and temperature.

I'm so confused... You know that ordering not stock sizes gives you weird grip, but at the same time you're getting grip and not getting grip...


It's simple, your sidewall flex/wobbliness is 100% due to the wrong tire size, doesn't have anything to do with the wheels. So that's why you're not getting the correct grip...

I know what it is from, indeed this is true, my point is that with all my research and user reviews, I believed this would not be the case with these sizes, many have went to 275/305, that would be a sheer disaster I am sure. I want to avoid others doing what I just did, believing all the hype of plus sized tires. Going lower on PSI will only make the problem worse, 40 has made it slightly better from 35. By grip, I literally mean that, they are sticky tires no doubt, even when we mounted the tires however, the sidewalls felt flimsy imo.

grip= sticky
sidewall= soft
= poor steering response and flex on the sidewalls.


To clarify my overall goal of this thread is to inform those thinking of plus sizing because everyone else has done it and says its great, there will we negative impacts in my opinion, that's all!

Fair enough sir! I was just a bit confused, got it now! :tiphat:

I wish they made a 285/35 for the rear, just to get a BIT wider, but not wide enough to have they problem you're having


EDIT: I hope they swap them out for you, but I'd lie and say your wheels are wider? And say look, I'm going to buy narrower wheels that's why I want narrower tires or something.
Because they won't like that you didn't use stock tire sizes

Indeed, but the tires are still within an acceptable range for the width of the wheel. We are a Michelin tire dealer at work(although we mostly deal with yokohamas) I have had nothing but pleasant experiences with Michelin CS, guess I will find out tomorrow!

that is the exact reason I went 295/30, I wanted to run 255/35 and 285/35.

The title is misleading. Should say: not digging oversized tires for my rims.

Well according to every account on this forum these tires over sized are nothing but amazing, so eh, not so much misleading, I am just disagreeing!

Eh, I kind of disagree with most being said in here. I don't think the swap to a 265 and a 295 is the issue. He's within Michelin's recommended rim size with tire size even though he has the minimum recommended. I think its the type of tire that is in question. He came from RE050's and S-04's which we all know have stiff sidewalls and are pure performance oriented. Michelin PSS as we all know ride beautifully, last long and have gobs of grip. Anything with the Michelin name has some LUXURY ride quality to it. How do the PSS's get that? More sidewall flex which is what I think the OP's main complaint is about. If you look at the PSS's before they are even mounted, they have more round sidewalls then most performance tires out there. People always compare the PSS and RE-11's and the easiest way for me to explain it to them is

PSS = Trackable street tire
RE-11 = Streetable track tire

There's plenty of us running tires with the minimum recommended width of rim and no complaints. I think this is more related to the tire construction itself then the "oversized" tire complaint that everyone is jumping to.

Thanks for the info! Only reason I an going after the oversize is because you can visibly see how far inset the wheels are on the tires, thus giving it more room to wiggle around, the stock sizes have an ever so slight stretch to them. I guess my surprise was if everyone else's car feels like mine, how the heck does everyone like them? It corners yes, but I cannot like going in a corner at 60 or 70 and feeling the sidwalls give a little, guess I just have higher standards! I was going to go with the s-04 again, I was happy except for the tread life, we live and learn! Im sure I will have no problem unloading them used if it comes to that, only 500 miles on them! The re-11s are a step above the s-04 and I figured I would get better if not equal from the PSS since it is usually placed higher than the s-04.

This describes it well, kind of supports both cases:

Lost Motorcyclist: How Sidewall Flex Works in Lower Profile Tires

I'm sorry, but I have to disagree with most of you. Michelin tires are not a true performance tire. If they're advertising 40K miles, that's not a performance tire. You have to make a choice. Performance or tire life. I'm running Nitto Invo's. I really don't expect to get more than 15K miles out of them.

There have been countless tests(assuming the fault is ME and poor size decision not the tires) that prove the PSS is the benchmark performance tire, unless Michelin is paying them all. Tread life warranty is a marketing tool, it keeps you in that brand of tires, Michelin is smart to do this, and its 30k, and they cut that in half for staggard tires, so it is really 15k ;)

LOL @ Invo's outperforming PSS's. The tire world isn't what it used to be thinking that just because the PSS's have a mileage warranty that they cant perform with the best of them? Thats just stupid logic. Michelin is the top tire manufacturer in the WORLD and has some of the most expensive tires you can buy. For the right price, you can build the best of both worlds which Michelin did. Just have to say I literally LOL'd again at the thought of Invo's outperforming PSS's.

Yeah the PSS will walk all over Invos, which are a pretty lousy performance tire by today's standards. Marginally better than the Hankook V12.

:icon18:

made that mistake on my 350z....:eekdance:

LOL. The SS was specifically designed for the 458 italia...I'd consider that a high performance car. It's the favorite tire for many R8, Mseries, corvette and 911 drivers. It's an amazing tire and can't wait to get my set mounted on the volks.

The supersports are definitely a performance tire, just not a track compound.

They're also known to have softer sidewalls. It's why they weigh less than other tires by a few lbs I think. I'm guessing it's the combination of running a bit oversized, your driving style, plus sensitivity to feeling the wobbling. Does the tire lose grip when that happens?

No does not loose grip at all, its just annoyinghaving to learn to drive the tires so to speak, I know they are not going to slide or break loose, its just an unconfortable feeling for me. I have made the decision if I can sell them local I will switch, if not, I will live with it, maybe its a blessing in disguise, it will slow me down a bit ;)

Not sure if it's been mentioned or not, but new tires almost always feel softer because you're going from no tread to full tread.

That comment about the PSS not being a true performance tire should get that member banned LOL. I have put several thousand miles on my PSS and I love them. I'm running 255/295 and have never had any issues. Having longer thread life is just a plus for me.

am i missing something here?

Tire Details - Discount Tire

they sell a 285/35/19 in the Michelin's

I just checked tire rack, they have them listed now too but do not have them...hmmm really mucked up haha. I got a standard repsonse, "The size has nothing to do with how the tire handles its all about the compound on the tire and it will make no difference if I trade sizes"...oh well.

My Hoosiers feel like crap compare to my RE11, yet it is a lot stickier. Sometimes you just have to deal with it.

just heard from tire rack, they are willing to swap them, I have to front the bill for the new ones up front, then they will reimburse me.

Wow, that's awesome!

Promotion - Discount Tire

what about looking into this. i thought if you didnt like them before 30 days you get a new pair.

Promotion - Discount Tire

Tire rack honored that, Michelin would not, stating the size did not affect the the sidewall rigidity, only the tire compound. New ones should be here tomorrow, I wantto get them on and the old ones back asap to get my $1200 credit, my CC company is in love with me right now haha.

Ok the verdict is in, I got the stock sized pss on, and yes, the size was 90% of the problem. The steering response still is crap on these tires...I honest cannot understand how people on these forums bashed the stock tires so much, they had better steering response and stiffer sidewalls, and the re50a is not regarded by the people as a good tire...and mine were dry rotting away, that's why I changed them! ANYWAY, I am much happier now, the car does no roll like a boat at sea in corners now, and is acceptable. Will I ever buy pss again, not at this price point, IMO they perform in the 700-800 dollar range, the KDWs on my 350 are similar to these in handling and grip, makes me wonder about the new BFG, might have saved 400 bucks...if I changed these out again, I would do this, 255/35/19 F and 285/30/19 R, this will go a tad wider but keep the sides short, yet shorter than stock, but it should help with steering response. Michelin has everyone brain washed, sorry guys, I agree 100% with Honestyhttp://www.the370z.com/north-east-re...ml#post2306476, and I am running these at 40 PSI now, I want to back them off to 38 and see if that is ok. Keep in mine I still have to break these in, ram around for about 50 miles after work tonight they are still a tad slippy

M4a1Mustang,

That's got to be the most awesome avatar I've ever seen.
Labyrinth was one weird movie, but I really liked it.

I never run my tires bald, the front were still 6/32nds but dry rotting and hardened, the rear were 3/32nds.

As stated before, most people on this forum don't run this car as hard as you or I do and the people that do are running the RE-11's, AD08's, Direzzas, RS-3's or something of that caliber. Basically a step short of R-Comps. The PSS's can handle some track time but they are built for the streets. Aggressive corner carving like I do, I wouldn't last long on the PSS's as I've driven my friends 350z on them and they do bite but not enough steering response as you said. Not only that, at 40 psi, you're not using anywhere near enough contact patch to get the full effect of the traction they provide. 32ish would be ideal.

how many miles have you put on them? did you let them break in atleast a little?

32ish is low... 3psi lower than factory recommendation which is already kinda low geared for comfort. if the tires feel good at that psi, then there is no way in hell they will have the firm-ish ride i want.

thanks for the info! :tup:

Can't wait to get the PSS for my car. Those tires made a big difference with my beater 06 Civic si.
