Pirelli pzero nero m+s

[ladybug04]

welp, got some new tires on the back of my car, decided to go with the pzero neros, got em on, and got a few miles on em(bout 100) and took em out on my testing corners, and my impression on them is this:

good grip, didnt get them to break traction, so plus there.

but in the corners, they would never settle down. they feel like they are ballons on rims. the sidewall is waaaaayyyyyyyy too soft. ill see how they do at auto-x here in bout 20 days. but i will never buy pirellis again, as both types of tires ive had from them have just been substandard. i know they are discontinued now, so i cant return them, and order a better set of tires.

so please learn from me, and dont get the pirellis just cuz they are at a great price point right now. they are ok for straight line driving, and normal grandma driving, but thats about it.

What size? You also said you only put them on the rear? Whats on the front now?

I had P-zero Nero M+S's 215-45-17's on my SVT and I loved them, the handling was fantastic and the ride was good.

I ran them year round here and they even did well in the snow.

I would have bought another set but I couldn't afford them at the time.

Sounds like you need to adjust your air pressure.
I found the sidewalls to be Quite Firm for a Non "Race" tire.
Best Tire I've ever driven that is an All-Season.
I suspect user-error.

[focusownerskid]

I've had a set of those, best all-season I ever drove on.

I'd bet air pressure or in need of driver mod

So, Please reader Ignore this post until you go on a run through the twisties with me on a set.
(OR, you can Trust the thousands of Other users who have used them on various vehicles and given Rave Reviews... )
He even said that he didn't get them to break traction...

The tires give EXCELLENT feedback, they do NOT "wallow", and they are the Absolute Best tire for Cornering that can double as a Commuter tire with decent treadlife.
This thread puzzles the crap out of me.

[FORDSVTPARTS]

Hmmm, sounds like all the SVT owners like the P-zeros.

[ladybug04]

well, to be fair, i do need an alignment, but i had almost wore out kelly fierces on the back, and ran them through the same twisties, and had much better feedback and not near as much feedback as these, i have the pressures up at 42 psi. unless, when the shop put on the tires broke something(dont know how that could have happened as i watched them install them. ill try gettin some new bushings and an alignment, then report back. they are a good sticky tire, just the sidewall is too loose for me. and reason i have them on the back is i have dunlop direzzas on the front, and want them up front to provide better grip during auto-x.

oh and BTW i have the H&R cup kit, had it for quite a few miles, bout 40k. and im running 215/40/17, and i wasnt pushing the envelope, i was doing my normal test the tires out by gradually taking cornerws a little bit harder, to learn how the tire reacts. round a 25 i was prob doing bout 45.. can do it quite a bit quicker then that.



ill do some checking on my car, and see if it is tires, or mechanical.

ok, well your not still not getting the full ride and "feed back" from them since they are on the back. Cause the feed back you are getting if from the Dunlops, so its the dunlops that are having the softside wall. Untill you get them on all 4 corners you will not recieve the full benefit from that tire. And why are you running 42 psi? Thats way to high, even for auto crossing.

Cause i garuntee you the treadwear is completly diffrent and well as the temperture & traction ratings. Your comparing 2 diffrent tires. on the same vehicle.

[ladybug04]

lololololololololololololololololol

dunlop direzzas have too soft a sidewall lmao are you crazy?????????

and i run my pressures where it works for me. i do pretty well at auto-x, so it aint driver. im telling you it is the rear end swaying, believe me, my (quoting lorin as good as i can remember) organic yaw, roll, and lat6eral sensors are pretty well soon, i have had other people ride in my car, and with all types of different tires on it, and guess what, my ass didnt start being so unstable till these pirellis were put on. now it may be something broke, but i doubt that. ill have tyo check, and please do a little bit of reading before you start trying to tell me that the dunlops are the tires im having problems with- they are one of the top STS tires. and yes i do need to play with my pressures a little bit, i know that,but right now they work just fine, i did 42 to try and stop the sidewall flexing so much, and it did little to help. maybe when they installed the tires, they messed up the sidewall i dont know

kthxbai.

[AcIdBuRn02ZTS]

im running the p-zero nero's (non M+S) and ive never had any kind of issues like your stating... i would check tire pressures and alignment... perhaps something else is causing the issue you are describing?

-AcId-

[ladybug04]

thats what im kind of thinking, alignment, and bushings, and maybe bearing, heard a little bit of noise from the rear today.

car has 112k miles on it, although i didnt start having these issues until these tires were mounted, so i dunno.

You can't mix and match tires and expect the car to behave properly, both ends are doing different things.

Besides the fact that one is an ultra high performance summer tire and one is an all season.

Put on four of the same tire, either the Dunlops or the Pirellis.

Put a set of full on race tires up front with the Dunlops out back and see how it drives, It's just not a good way to determine tire quality.

[AcIdBuRn02ZTS]

i had a wheel bearing fail the last time i rotated my tires... it was less then a week and i started noticing the car driving funny and making noises... rear wheel bearings were done at around 99k miles...

get it up in the air and check things over for play...

steve also makes a good point...

Well said!

The analogy of shoes can be used here. Try wearing a cross-trainer on one foot and a dedicated running track shoe on the other, and run a 500-metre race.

If you can, try to swap your tires with a friend or another member here who has the full set of Dunlops or the Pirellis and see if it is the tires themselves. If your car still wallows with all four identical tires, I'm tempted to say it's something else. If it really wallows (or doesn't wallow), you can start to look more into the tires.

I'm not sure I should post this. However, having experienced this symptom with several Pirelli's I feel I should share the view.

You will not find a more devout Pirelli banner waver anywhere short of Italy. I've been a pretty much exclusive Pirelli user for decades and for good reason, after probably at least 300 tires since the 70's, I have never been left anywhere by a defect in build nor ever let down by performance.

However, of late (since the Nero was a new model) I've been noticing something interesting about the Asymmetrico (one set), Rosso and the Nero. Anytime I get these installed new, they exhibit this soft sidewall symptom when first mounted and before any heat cycles or settling in can occur. I can't explain it but the last several sets of all 3 of these model tires have done the same thing. After a couple heat cycles and a few miles (around 50 or so) either the belts seat or the the rubber cures or something but the unsettled handling went away. The Nero's were the first I experienced this with, and it's happened with two different sets.

Check the pressure again, and give them a heat cycle or two and try them again. I kinda doubt this symptom will last.

[MichaelXi]

Rodewaryer, I'm guessing they still had the sealer from the molds on them, and you wore that off after about 50 miles and the heat cycles?

That's typical for most tires these days.

[Johnny_P]

drive them a bit

and run lower pressure in the rears (~5 psi less) than you do in the fronts.... on my Azenis I run 40 front 35 rear... that seems to do quite well, but I could probably even run less than that

I have noticed this with my last couple sets of BFGoodrich's (two sets of g-Force Sports and now my T/A KDW's), and I believe its along the lines of what MichaelXi said, its the initial "glaze" on the tires that goes away after a couple heat cycles. Basically the premise behind race teams "scuffing in" a set of tires, get the glaze off of them.

[ladybug04]

yeah they have settled down a bit, but i think some new bushings are in order. and i have a rear sway on the way soon too. ahhh so much to do so little time/money

[sleeperlove]

sounds to me like matching tires all around are in order. Its absurd to complain about lack of rear grip when you have super sticky summer tires on the front.

[ladybug04]

its not grip im worried about, its the fact that the rear end was swinging around, as in shifting in mid turn, which it did not do before with less grippy tires i had before, but if you read my posts youll see that i have deduced that it is prob not a tire problem, but a bushing/ alignment problem, but thx for the info

bryan

[Johnny_P]

are you sure its not the passive rear steering? that can make the car feel squirrely, when its actually not slipping at all.... quite possible with grippier tires on the rear.

[ladybug04]

the grippier tires are on the front, and yes im sure its not the rear steer, i am totally used to that, and take advantage of it, its basically the rear steer, but because there is so much slop with the bushings/ etc. it is overdoing it. im gonna try popping on a sway bar, and replace some bushing, and see if that helps
