Tires pressure F12 TDF

Is someone could give me the tires pressure for the TDF ?
Thanks a lot

 

Info is in the manual and on the door panel

 

I know, but i own an F 12 and i m searching the best tire pressure for my news S007, near of an half slick.
That s why i ve need TDF pressure numbers in order to compare

 

Here you go....

Thanks a lot !

 

Exactly what size are your tyres? Cannot see the S007 being available in neither the TdF or F12 size as a full set - same goes for the S007A.

Also, are your tyres the S007 or S007A variant? The reason why I ask is this. First off, neither of them are as aggressive as the PZC4 TdF tyre. The S007 is comparable to the MPSS and the S007A is somewhere between an MPSS and MPSC2, so more aggressive than MPSS, but less than MPSC2. The main difference between the S007 and S007A is the tread design. They do however, use the same compound. To illustrate how they differ from the MPSC2, you can look at the wear rating. It is 240 for the S007/S007A, but 180 for an MPSC2. This indicator works well as a guideline of how soft the compound is. The F12 Pirelli and MPSS has a tread wear rating of 300, so not that far off from the S007's, Now the TdF tyre however, has a wear rating of 80. By comparison, a Trofeo R and MPSC2 R is 60, so it is basically as close to an R compound as you can get.

Getting back to the size. Is the case that you run an S007 in the front and an S007A in the rear? This is the only way I can see finding this tyre in the F12 size.

What I'm trying to illustrate is this. Unless you are using a different size than OE, you should stick to the OEM tyre pressure specs. The compound has generally little to do with,what the pressure should be, but tyre size is important. Not only does the TdF run a much bigger front, the car also weighs less. There's a very good chance that the TdF pressure is way below what you need, and you should also factor in that Ferrari tends to run pressures on the low side of things. Your car calls for 32 psi rear and 35 front, That higher pressure is because of two things. One is the narrower tyre and the other is the larger weight. If you look at an 812 for comparison, you get a better idea about it, because it actually specifies pressures for both 275 and 255 section fronts. The 812 is comparable to your car in weight, and the 275 tyre needs 33.5 PSI and the 255 needs 35,so the same as your car. Trust me, 32/32 is not what you want, it is way too low unless you run something crazy like a 285/35R20 front, which you don't. Again, don't forget that Ferrari for some reason unbeknown to man, has a tendency to run slightly low pressures, so if you run the stock size, either use OEM pressure numbers, or perhaps try 36/33.

 

Thanks a lot for your detailed and instructive answer.
I ve found a complete set of S007 ; 265 /35 for the front and 315 /35 for the rear . Full S007 and not S007 A. I m not based in USA .
I ve run about 100 kms with this set up.
It s really impressive. I ve a very good feed back and i feel so much grip.
Much better than my last P zéro. No comparison.
On my car, i ve TDF spring, TDF ground clearance and alignment . It works very good because stabilizer bars are stictly identical between F12 and F 12 TDF ( same diameter and same reference )
I m seaching the good tires pressure and i ll follow your advices.
With Pirelli, factory recommandations was 2.2 bar for the front & 2.1 for the rear
With Michelin Supersport, it was 2.3 for the front & 2.2 for the rear

 

Okay. Just did a check, and you're right about the size. 255's are available here in Europe.

Anyways, seeing that you have upped the size in the front from 255 to 265, it might be worth trying a pressure in between. 2.35 bar is a good starting point for that size in the front. Had you run 255's, it should probably be left at stock 2.4 bar. The 812 uses 2.3 for 275, so 2.35 is a good place to start for that size. The S007 is indeed a nice step up from the PZero's. They were the worst of the tyres offered on the F12. The S007's feels very similar to the MPSS and is in the same category of tyre - a very nice choice I think you will be very happy with Stick to OE rear pressure until you have dialed in the fronts, no need to faff around with that, as you have not changed that size. You can try and increase it .5 of a bar and see how you like it when you have a bit of seat time. Your new shoes will need a few hundred km to really come to life.

How do you like the slightly wider fronts? Many here speculate that running wider fronts on the F12 is a no-no, as unlike the TdF and 812, it has no rear wheel steer. They seem to think it will oversteer right into the nearest tree. However, there are quite a few in my region running TdF wheels and tyres on the regular F12, and it works really well. A stock F12 has a lively rear end due to power, but as actual steering response and balance goes, it has quite a lot of understeer. I reckon that you in part feel the car more planted due to the added from end grip from those 265's, A pic of the car from the side would be great. Never seen an F12 with that tyre size. I'm sure it looks great

 

I m coming back to my garage, and it s 255/35 for the front ; sorry for my mistake.
I ll take pics as soon as possible because we re lockdown...
TDF springs are 35 % harder and it makes a huge difference VS stock. The car is more stable with the right / left changes, more precise and more incisive.
No skating on the first and second gear with huge acceleration. I ve lot of camber and max toe on the rear.
I feel the car most agile
I ll try 2.4 b for the front and 2.2 b for the rear, thanks a lot !!!
Next step ll be BMC air filters and full inox exhaust line with 200 cell

 

Sounds like you have a good setup. Have you adjusted camber or toe? If so, what numbers?

With that size of tyre, keep to the stock pressure for sure. You can try and add or subtract .5 of a bar and see how you like it. Don't forget to set the pressure in the morning prior to any driving when the wheels are properly cold and haven't sat in the sun. If your car is parked in a heated garage and the temps are significantly higher than outside morning temps, set them at least .5 bar higher. These pressures are cold pressures and needs to be set in relation to outside ambient temps. Rule of thumb is to set them in the early morning.

 

Sorry for the late,



Ground clearance :
- front = 130 mm
- rear = 150 mm

Alignment : for earch wheel

- front =

cambert : - 1° 30
toe : - 1,3 mm
caster : 5°10

- rear =

cambert : - 1° 30
toe : 2,4 mm

TDF springs, TDF ground clearance and alignment, new Bridgestone S007 ( 2.3 b for the front & 2.1 b for the rear )

I would like TDF / 812 rims with 275 for the front, instead of 255. What do you think ?
