Pirelli tyres

[markimark]

Hey UK folks. How are you finding the Pirelli tyres now the colder weather has arrived. I have noticed a lot of trye judder and the back end slipping even in mildly damp conditions.
Are any of you moving to winter tyres and if so....which in the UK?

Cheers folks.

These Pirelli summer tires are exactly like what they say they are, for summer.

They are no good in cold weather. Winter tires are needed.

I have Continental winter tires.

Its bloody hard to find Continental TS870s in the uk!!!! Can only find the TS860 for the front and 870 for the rear!!!
Also the speed rating is V not Y - how does this impact insurance?

No problem for me at all so far (-4C this morning). They are certainly better than the PS4S I had on my S550 but just be gentle with your right foot.

The worst seems to be salted roads around 0C here in the UK when damp. Cold and dry, no problem, snow and ice - why would you drive in that in a Mustang?

This is my DD so I have no choice!!!!

Me too.

You always have a choice to not drive in snow!

Fair point my friend LOL

I had Michelin PS4S on my Audi, which is all wheel drive (Quattro, basically a torsion differential that sends power rear or front up to a 60/40 rear front distribution) and drove them year around with no issues, but I live in the US southeast. I would drive them when temperatures were in the 20s and 30s Fahrenheit, below freezing, and I did not experience any issues. I never drove them in the snow, however. I think I had some Michelin Pilot Sport AS or something like that the last time it snowed, and it drove just fine.

What was wrong when you drove with the PS4S on your S550? I ask because I am considering getting the PS4S for my Dark Horse to replace the Trofeo RS (which are laughably slippery below 50 degrees ambient - I don't even try to drive them below 40 degrees).

I found the PS4S became fairly poor below 0C giving some exciting exits from roundabouts! I changed to Continental Sport Contact 7 on my S550 and they were MUCH better. They have a different branding in the US market, but the same tyre. I would say the PZ4's on my S650 are a match for the CSC7

Of course the S650 rear end feels more stable than the S550 anyway.

OK, I will keep it in mind to slow down a little when it is below freezing. Thanks.

"The Pilot Sport 4S excels in warm dry and wet conditions, so like all Max Performance Summer tires, is not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice."

and

"Note: Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels or using them to support, roll or drive a vehicle."

Flexing of the specialized rubber compounds used in Max Performance Summer tires during cold-weather use can result in irreversible compound cracking. Compound cracking is not a warrantable condition because it occurs as the result of improper use or storage, tires exhibiting compound cracking must be replaced."

Below 20 degrees is very rare where I live, but it does happen. I will keep this warning in mind in the future (never knew about it or paid attention to it before).

I'm lucky to have a second set of OEM alloys with Michelin Alpin 5 tyres which I can highly recommend if budget allows. I ran them from the beginning of January to mid-March, and the grip was night and day compared to the Pirelli's. Probably overkill for the UK, but it gives me confidence in the car when weather conditions are poor. I put them back on yesterday just as the snow started melting!

From my experience last winter in the UK (something has gone really wrong if it gets down to -7c here) the pirreli's need a bit of heat in them to grip properly.
Stop/start traffic and 20mph zones are enough to lose temperature that if you give it the beans again too quickly the rear will snap / kick around 5k rpm in second.
The DH isn't my daily driver so if it's cold / wet / snow / salty roads i'll take the merc which i put the blizzark's back on last weekend.
Infact i've done a whole 35miles in the mustang in the last 2 1/2 months.
It's in for the recall tomorrow.

I had PZero summer tires that came on my S550, they're junk for the price and I don't get the hype behind the name. Michelin PS4S really are as good as everyone says but still not appropriate for colder temps but handle them better than PZeros in my experience. It gets cold enough to damage summer tire compound here so I swap to winter tires. Even if you get little to no snow, winter tires perform better in cold and wet.

The P Zero on the S550 and the PZ4 on the S650 are very different tyres
