I know this topic has been talked to death, but my car was delivered with Pirelli's, I have had the p4s fitted for a few weeks now, and the difference is quite literally night and day.

I am just baffled as to why - surely the BMW techs etc all drove it with the p4s - they must have felt the difference the same we all do, why deliver with Pirelli's? I am guessing it was a commercial decision?

When I test drove the M5, it had the Pirelli's and I really was thinking twice about the car, every time you put your foot down it was lighting up the rear tires or cutting power for traction - felt all over the place in the corners, and that was in a 20-minute test drive.

I am glad I took the gamble, the car is a different animal now. Well on par with my old RS6 for grip etc.

I have a post on this forum explaining why I thought the xDrive was so shit compared to the Quattro, it turns out the xDrive is fine, it was just the shite rubber they deliver 70% of these cars on.

I agree with you. I went from pirellis to 4s on my last car (M6 GC) and was night and day. I plan on going with 4s again when my pirellis on my M5C wear out.

There has to be options for supply side issues. In order to satisfy that requirement the secondary vendor will demand a certain amount of production guaranteed.

If this weren't in place and the primary supplier had an issue (factory fire, natural disaster, etc) BMW would have to shut down production possibly for months. Pirelli was probably the least bad option for them.

This ^. As well, I recall something about Pirelli developing a “tire especially for the M5” but then again, most likely, this “development” is just a marketing excuse / justification and of course doesn’t guarantee a superior product.

Do the 4S s feel any stickier, from the point of picking up little stones, and clattering them in the arches etc ?, my car on Pirelli’s, feels like it’s picking up everything on the road, and firing it into the arches, interesting thread Danny.

[DannyA]

Strangely I have not felt like its picking up stones - do you hear them when driving? I find the f90 pretty much silent when driving, the sound insulation is very good.

No issues with the Pirrellis on my M5C.

I think in the dry it's not quite as noticeable (looking at your location) - I drive on wet roads a lot and it really shows how much better they are.

On the Pirelli’s, I can hear lots of stones/gravel being picked up,by the tyres, and hitting the insides of the wheel arches. It was from another thread, that said they thought the Pirelli’s were stickier, so just wondered if you had noticed any difference, but sounds like you haven’t. Obviously, it’s probably the different states of the roads we are travelling on that is also making a difference here.

[DannyA]

Yeah - not scientific at all but feeling the p4s by hand they feel more tacky (sticky) then the pzeros - it's a totally differnent compound

Did someone say "sticky"?

Same here. Quiet, grip fine and no stone throwing. I'll be putting Michelins on when the Pirellis wear out, but I'm not in any rush.

[euro*]

Yeah all the pirelli's are good for, is picking up all the small rocks and throwing it up to my side mirrors.....

Can't wait to run Ps4s next year

[Miko M]

Cars like M5 needs to have tire Treadwear below 200 for better grip.

Specially if the car is tuned

[subterFUSE]

It is a crime against humanity for any company besides Michelin to make tires.

[northtorque]

I agree that the Pirellis are super sticky and pick up crap - I have a gravel drive (3/8” bluestone chip) and these Pirellis are picking up all sorts of stone and creating a chatter (Thank god for PPF). Really noticed the difference when I switched over to the winter Michelin Alpin PA4 which pick up very little in comparison.

[Simon H]

I made and fitted these to both of my F90 M5s, they are hardly noticeable, and they do seem to work. My latest M5 is black, and they blend in really well.







At their widest, they stick out 1".
