3 sets of wheels for 612, need tire sizes

Paging the Air force Vet from Arizona...

 

Front 245/35 ZR20
Rear 285/35 ZR20

As to brand, right now I am having a set of the new Michelin Pilot Sport 4S mounted. I've had the Pirelli P Zeros with no complaints, but everyone raves about the MPSS, so I thought I would try these new ones from Michelin. Reportedly they are even better.

 

I have an 07 612 with Michelin Pilot Super Sports. They replaced P Zeros. The Michelins are far better in terms of grip, noise and longevity. Nuff said?

 

MICHELIN PILOT SUPER SPORT is the the one that everyone is using on the forum, you will see only positive feedback about it
Please note that the Pilot Sport 4S is not the same, it could fit but this is more for sportive daily driving, not for Supercars
On the Super Sport, you will find different K approvals (Ferrari Spec), the higher the number, the more updated the tire is, K3 is the latest I found, but K1 and K2 will be great too, not always easy to find the front and rear in the same K and it does not matter, most Ferrari dealers, will put what they find and are not sticking to the same K front and rear
There is a tire alternative for very sportive driving, they call it the road legal race tire, the Michelin Sport CUP, It only has 4 mm thread, and is therefore lighter, a real track day tire for those that don't cary racing slicks, it should be superior to the super sport but not done for mileage and prone to aquaplaning by heavy rain.
I think the Super sport is the best all rounder and will do good even on a track day as long as you are after fun and not lap time.

 

The 4S is the replacement for the MPSS.

 

I would not buy the MPSS unless they are significantly discounted from the PS4. As more sizes in the PS4 become available the MPSS will be more difficult to find, or replace if you have one tire fail. Not to mention that the PS4s perform better than the MPSS.

The Science Behind How Michelin Made Its Best Tire Even Better

 

Hi Taz,
You are right, I did not get that one
Just read that they are the oem GT4 Lusso tire
I am wondering if they would be adapted to older models like the scaglietti, why not in the end... but I am not a tire expert.
Michelin still recommends the super sport for the scaglietti on its website

 

Got my car back today with the new Michelin Pilot Sport 4 S tires.

I'll be leaving for the FCA Annual Meeting in Daytona, and then continuing on to Key West. About a 4000 mile round trip. That is what I call a real road test!

Hey there,

I am facing the same dilemma. I have just purchased a 612 with HGTS on the 19" modulars but am going to switch them out for some 20" Challenges. Still debating whether to go for the Michelin Super Sport route or opt for the new Pilot Sport 4 S's. Also not sure what width to go for on the rears as many have talked about rubbing on the inner arches, and with the HGTS, I wonder whether this might be an even more sensitive spot.

Any thoughts would be highly appreciated gents!

 

I believe the rubbing issue was with the 599 wheels being fitted on the 612 as they have a different width and offset. It was resolved with spacers. Check this thread...
Careful if putting 599 rims on 612!

Hi ZDF,

Thanks. I fear that's the problem I may encounter as the set of Challenge wheels I am looking at are indeed the 599 set (11" rears).
I am going to see if I get away without spacers as I would like the most simple set up possible.
If anyone else has any thoughts or experience, that would be great.
Right now, I am considering Michelin Pilot Super Sports, going for the K2 versions, giving me 245s upfront and 285s at the rear.

All the best,

Jit

 

No problem with the 599 wheels on 612s until owners went to GTO size 315/35 20 tires. The OEM 612 tire size of 285/35 20 or one tire size larger at 295/35 20 will fit and give no problems. The 599 offsets are set up such that ~1/2" of the extra width goes inboard and the other half inch goes outboard. If she were mine, I would probably go with the 295/35s to take advantage of the extra inch of wheel width. 599 fronts are the same width as 612 fronts.

Taz, you don't cease to amaze me with your wisdom.... many, many thanks!
Regarding my choice of 285s for the rear, the only reason I have done this is to go for K2s all round... 295s don't come as a K2 on the MPSS, just as K1s.
Would this alter your opinion? I like the idea of an extra inch of rear rubber especially on a RWD V12, but wonder if that is compensated by the better tread and tech of the K2s versus the K1s. I am still unsure in my naivety whether the HGTS package has also altered the suspension such that the rubbing may be more prone on cars which have the suspension pack specified. Thanks again, Jit

 

JS- K2s are a better deal for street Ferraris because they have an extra chunk of tire tread depth (a whole 1/32") so last a little longer. The K1s came with shallower tread depth for a little extra stability not really needed except on the track. 285s will work fine, and the difference in width on the 285s and 295s is only 1/2" per tire. The K2s were originally fitted to the F12 and the K1s to the GTO. I should have looked at TireRack to see if both were available in K1 and K2 before posting.

 

Taz, you are a star, I now know exactly what to do... and to a 612 newbie, the Challenge wheel dilemma is far from a simply one. But K2s it is!

 

Terry, may I please ask you for one further piece of advice? Apologies for taking liberties with your knowledge. I have now purchased the K2 tyres as per your recommendation and the 599 Challenge wheels are on the way. The 612 I am buying has a TPMS installed. I wanted to ask a naive question... in order to fit TPMS sensors, does the wheel itself need to have a space to accommodate the sensor? In other words, is it possible that the Challenge wheels I have bought may have belonged to a 599 without a TPMS and therefore this will render my TPMS system redundant because the sensors can't be housed on the wheels? I am looking at new sensors as everything else is going to be new (wheels, tyres, caps, valves). Any advice would be gratefully received.

 

JS- The TPMS sensors attach to the tire valves, so no additional holes are required and all the wheels are identical.

 

Thanks a lot!

 

Terry, one more irritating question for you.
Would you recommend the following?

Thanks,

JS- That is a great deal on the OEM sensors.

 

Hi Terry,

Sadly the seller told me they won't fit the 612: I apparently need the RDE001 sensors.
Hopefully someone with a Ferrari other than a 612 can benefit!

 

JS- They changed the sensors so much in later years, I could not keep up. Amazon has the now Huf RDE-01s at a reasonable price once they get some more in. Beru originally, then Huf-Beru, now just Huf.
