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.
