Michelin vs Pirelli, Super Sport vs P-Zero

Low pressure can also cause high temps, but it takes a pretty low pressure. In my example, high temps are caused because,the high pressure decrease the contact patch.

With an 812,GTS I think a nice hot pressure for Michelins are about 2.2 front and 2 1 rear. That keeps them pretty stable.

Now the F8 vs. Huracan is very valid. But it has to do with weight, setup, power, and the cars intended use. But more impirtantly, there's the factor of mkdel specific tyres. There's no telling what Lamborghini had the tyre manufactures change.

So while one might think it should be apples to apples, it is not. Hell, stuff such as cooling matters. Does the air from the radiators contact the tyres? As any 488 owner knows, the left front runs hotter due to this. Hence also why a well dialed in tyre pressure setup takes such things into account.

Thanks for the response, very interesting. I might try a small increase in my F8 cold temps, say 2.2/2.1, to see if what helps them generate a little more heat.

 

Exactly.... who wouldn't enjoy this

Just come back from a quick drive in my 812 and I made an extra effort to see how the PZ4s behaves. It's a cold but sunny day with us today and switched the right hand screen to the TPMS setting. My tyres started off on 2.1Bar front 2.0Bar rear and tyre temps were about 15-16C. Straight off the 812 was following cambers like a dog after a rabbit but after 20 miles of steady driving the temps increased to 26-28C and the car settled down with much less tramlining.
They are pretty bad until temps rise but not a complete disaster with some heat in them.

 

I agree totally, my 812 on PZ was the same, but start 10C lower and it’s more of a losing battle.

 

I had to drive my 812 GTS in the cold in rain on PZs... it was like being on ice skates. Ordered the Michelins for installation this week.

I ran into the same problem with Pirelli Zeros on my Cali T this past summer. Tire blew out while cruising on highway at 70 mph.

My F8 spider also came with P Zeros. They are bad. I only have 500 miles and just had a close call yesterday going into a turn. 35% throttle and I was fishtailing, TWICE!

Outside temperature was about 50F(10C)

Shopping for other tires now.

Any input on the Conti Extremes? I have had Conti DWS on my other cars and love them. I’ve never tried Conti Extremes.

Gents,

Michelin just announced that their latest version of the Pilot Sport 5 will start becoming available in early 2020, first in the EU then the rest of the world. Supposedly, recent third party tests have shown improvements over the 4S.

Read the report on an online auto site but can't recall if it was Autospies or Motor.1 or ********** (before they shut down completely last Jan.31).

Soon as the PS5S advertises on TireRack or my trusty local fireman, I'll be on them. I've been on OEM Pirelli PZeros before I switched to MPSP and the difference was amazing in terms of quicker response, better handling and "softer feel" due to Michelin's less stiffer sidewalls, which Pirelli tires are designed to.

 

And yet here we are in 2022 and no version 5.

Just to clarify, I meant not replacement for the 4S as of yet. It is important to stress that the MPS5 is the replacement for the MPS4, not the MPS4S. I have yet to see any proof that the MPS5 outperform the 4S. They are just different categories of tyres.

 

If you are ordering a new GTS, you can ask your dealer to tick the Michelin option box, code TYMX or Pirelli TYPP

 

The second link contains comparative tests performed by DEKRA or the German Motor Vehicle Monitoring Association. Available in the EU now but worldwide availability including the US will be on March 1, 2022.

Yes the sport 5 is available in the Europe at the moment but only in very limited tyres sizes for now. But I am sure that will get better with time.

 

Apologies for reviving this old thread..

About to buy a 430 fitted with P Zeros. I've been used to MPSS on my old 360.

In terms of getting the PZero "up to temperature" - what do people exactly mean by this?

Are tyres "up to temperature" after 20 minutes on a motorway, or does some spirited driving have to be done (presumably when grip is lower?), before the tyres are performing at peak?

Just curious as to how others get their tyres up to temp before they safely drive more spiritedly

 

I'd just bring up the screen to see the tire temp. IIRC, it's up to temp if more than 95 F...someone pls correct me if wrong.

 

Sorry I realise this is the wrong section of the board, but does the F430 have tyre temp information?

 

Where are you located? If you live somewhere with warm weather year round, then the P Zeros will be fine in general. If you read the thread earlier posts, the concensus is that if the weather is 10deg or above, then the Pirelli will warm in 20 miles of driving and then be fine. Actually, once warm, they may well be the faster tyre and so are good for track days and so on. If, however, you are somewhere colder and have times when the weather may be below 10deg, then I would throw the P Zeros away and swap to Michelin and it will take so long to warm the P Zero that you will not enjoy the car. If you experience rain, cold P Zeros and uneven roads, you will realise just how important grip is....

 

Thanks for that Outrun

To clarify - is that 20 miles or 20 minutes?? 20 miles and I might be back home?

Yeah I'm in Manchester UK. I doubt I'd use the car much when less that 50 (or 10 in the UK)

Your last few lines worries me a little :/ I must admit I have a big hard on for MPSS (not yet used the 4S) but the PZs are more or less new!

 

There's no set rule, 20mins of backroads will do they same as a motorway run.

I'm in Scotland so very familiar with your weather.....

If it helps, I took new P zeros off my car when i got it and stuck them on ebay. I experienced cold Pirelli on the maserati i had before the Ferrari and i just couldn't be bothered with the rubbish handling and grip. I drove the Maserati over the hills from Leeds to Harrogate once when it was about 5deg and damp and i have never been so scared. Couldn't go above 60 and the car followed every tramline and was unsteady over painted lines.

As I said, P zero on a warm track day or a summer trip to italy. Michelin the rest of the time (which is almost all of the time).

 

God darn it. Looks like my shopping bill just grew..

 

It's the only thing in contact with the road, as they say. So why compromise?

 

100%. I didn't realise I could actually be in love with a tyre before I used MPSS on my old 360

Pretty shocking to see so many bad reports of the PZ

 

To be honest, i cannot understand the bad feedback about the P Zeros.

Have the Pilot SS on my GTO rims in 285 front and 315 rear, drove them on my 599 GTB and some kms on the 812.
A very good tire, no need to take notice about something.

Now back on the original P Zeros, a very direct tire, much less comfort to the Michelins, but very good response and much grip.
Ok, now in summer i haven't the temperature problem, 40-50° C after 10 Km driving.
Let's see how they work at colder temperatures and if it's possible to get them warm.

Got the Monza SP wheels also with P Zeros in 21 inch, Monza Spec.
I didn't have them on the car, want to sell this set because i get a second in september in another color, so i can say nothing about handling with the 21 inch wheels.

Daniel

 

Hey Daniel thanks for that

I am hoping these tyres are the new "PZ4" iteration (collecting car in next few days). I'm gunna suck and see. The temps are still pretty high in the UK so I doubt I'll have issues. During winter I'll stick the car away anyway. Next spring I'll see what happens. Seems a big shame to bin tyres with 7mm on them!

 

Don’t bin the Pirellis. Store them with your dealer. Then fit them for summer track days. But for me Michelin PS4S much more usable and confidence inspiring on road. PZs we’re all over the place and would not get warm. Tramlining. Glassy in the cold/damp. Not great. Good on super hot day when you can drive the heat into them. But not otherwise. Subjective I guess.
My old PZs. Well, the unpunctured ones, at dealer with 6mm tread. Will buy one more and fit them for a track day. Then go back to the MPS4S
