Michelin Pilot Sport 4 Acoustic tires vs 4S

No, since the primary parameter for EVs is range, using a tire optimized for low friction is not what you want in sports/GT Ferrari.

 

No.

 

Stick to the 4S. The others are a HUGE mistake. If you are peddle down, merging onto the highway, and cross a dashed lane line, the backend will get loose, even at 100 mph. You need to respect the power of the 599 or it can kill you. Putting low traction tires onto a 599 is literally asking to die.

 

Key detail for purchasing MPS 4S tires - select the K1 compound option specifically tailored by Ferrari engineers to suit our cars' suspension characteristics.

The MPS 4S comes in different compound blends: M1 for Mercedes, N0 for Porsche, etc. By "compound blend" I mean that as related to how the various elastomer compounds (for dry performance, longevity, and wet running) are spread, blended and structured on the tires' treads according to tread width or percentage.

A week ago, I just finally switched my '11 599 HGTE's tires to MPS 4S K1 tires from the OEM Pirellis optimized for HGTE cars. The staggered set cost abut $2,400 including taxes, roadside warranty plus the annoying CA State fees. I can already tell it has improved the driving convenience, handling feel with quicker turn in around small or large radius corners.

My advise is to purchase the softest compound available for safer street driving (lower UTQG rating). Mind the old but true Pirelli adage "Power is nothing without control"!

After reading some initial tire comparo tests by EU authorities, the results indicate that the MPS 4S is still superior in dry performance as compared to the upcoming MPS 5 whereas the MPS 5 is better when driving in the wet.

 

You need to wait until the MPS 5S is introduced. That will be the one for our Ferraris and what I hope to replace my MPS 4S tires with. Many of the K1 Michelins have less tread depth than other versions, but that is not much of an issue for the average Ferrari owner.

 

Terry, I once read the different tread depths among the K1, K2, and K3 options but have somehow forgotten their variations.

Regardless, pre-pandemic shutdown Tire Rack used to list all three options but nowadays they now only list K1 and K2 as available.

Tire Rack specs list the K1 tread depth @ 9.5/32" for the 245/35ZR-20 size; K2 tread depth @ 9/32" for the same size.

Correct me if I'm wrong, but I thought K3 had the "shaved" surface whereas K1 featured a so-called "normal" tread depth. Other MPS 4S tread depth as specified for same size (without manufacturer designation) were @ 9.5/32".

 

I just remember that the 599 GTO tires had less tread depth than others in the MPSS line. Have not really looked at it in depth since then.
