Pilot Super Sports

As long as it's within 3%. Here is a great calculator I found:

Great pick with the super sports.

 

Careful!

The standard Ferrari F430 alloys (not Scuderia which has different specs as they are wider) are;

Front: 7.5" x 19" Inch (Standard fitment is 225/35 ZR19)
Minimum sized tire : 205 mm
Ideal sized tire : 215 mm or 225 mm
Maximum sized tire : 235 mm

Rear: 10.0" x 19" Inch (Standard fitment is 285/35 ZR19)
Minimum sized tire : 255 mm
Ideal sized tire : 265 mm or 275 mm
Maximum sized tire : 285 mm

Note: I have verified the alloy width data from the Workshop manuals so it is accurate.

Your front tire choice will fit (its the maximum possible) but you'll have problems if you fit tires > 285mm on the rear as they are only ten inches wide so it would actually be dangerous to fit 295mm. Don't do it!

 

Yes. That is exactly what I run on my f430: pss 235 and 295. No traction control or edif issues. Speedo is off a bit though. +4mph although ferraris are apparently notoriously off.

 

You shouldn't be running 295's on any F430 rim. They are 10mm too wide and will be flexing too much (285mm is the maximum permitted for a 10.0" rim) and could actually roll themselves off the rim when cornering hard. Also will be flexing too much and may even be rubbing on the inside edge on steering lock too.

Table of Rim widths to Tire Recommendations
7.5" Inch, Minimum sized tire: 205 mm, Ideal: 215 mm or 225 mm, Max: 235 mm <--- 19" F430 rims are 7.5" @ Front
8.0" Inch, Minimum sized tire: 215 mm, Ideal: 225 mm or 235 mm, Max: 245 mm
8.5" Inch, Minimum sized tire: 225 mm, Ideal: 235 mm or 245 mm, Max: 255 mm
9.0" Inch, Minimum sized tire: 235 mm, Ideal: 245 mm or 255 mm, Max: 265 mm
9.5" Inch, Minimum sized tire: 245 mm, Ideal: 255 mm or 265 mm, Max: 275 mm
10.0" Inch, Minimum sized tire: 255 mm, Ideal: 265 mm or 275 mm, Max: 285 mm <--- 19" F430 rims are 10.0" @ Rear
10.5" Inch, Minimum sized tire: 265 mm, Ideal: 275 mm or 285 mm, Max: 295 mm
11.0" Inch, Minimum sized tire: 275 mm, Ideal: 285 mm or 295 mm, Max: 305 mm
11.5" Inch, Minimum sized tire: 285 mm, Ideal: 295 mm or 305 mm, Max: 315 mm
12.0" Inch, Minimum sized tire: 295 mm, Ideal: 305 mm or 315 mm, Max: 325 mm
12.5" Inch, Minimum sized tire: 305 mm, Ideal: 315 mm or 325 mm, Max: 335 mm
13.0" Inch, Minimum sized tire: 315 mm, Ideal: 325 mm or 335 mm, Max: 345 mm

Correct rim width ensures flex at the designed flex point in a tire sidewall for optimum tire performance.
If the rim is too narrow, the flex point moves toward the shoulder area, creating heat buildup in the shoulder, which reduces tire life and could result in failure.
If the rim is too wide, the flex point moves towards the rim area, causing heat buildup in the lower sidewall, which reduces tire life and could result in failure.

You could also go with Bridgestone RE 11's. Better grip and way longer lasting. Pirelli are garbage IMO. Or you could go with regular Michelin PS2's. They make them in 285 width.

 

At the time of launch of the F430 the factory standard tire recommendations where;

Type of tyres:
- PIRELLI P Zero Rosso
- BRIDGESTONE Potenza RE050
- MICHELIN Pilot Sport 2

Optional tires (Run flat):
- GOODYEAR Eagle F1 GS-D3 EMT

Ofcourse you can deviate away from this but I am just advising from a width of tire to width of rim perspective. Don't go too wide on the tire if its going to potentially compromise its integrity.

 

They don't make 285 for pss in the required size as you probably have found out. I would try to get Re-11's. They were backordered nationwide until feb I think back when I needed tires in dec. I've run my pss' on the track at 150+ and tight turns without issues. They handle very well.

 

MPSS are a great tire but I would always be worried/concerned when running them "out of spec" of the rim size, especially at 150mph+ speeds! OMG! If one where to fail it could easily be good night. Also not even sure if insurance would pay out if it could be proven that they where the wrong fitment for the rim size, at the very least it gives them wiggle room, not good when stakes are this high.

To side step the lack of available size issue I think I'd rather choose Bridgestone RE-11's which do have the correct fitment and are excellent tires too.

 

Look back at the chart...

7.5" Inch, Minimum sized tire: 205 mm, Ideal: 215 mm or 225 mm, Max: 235 mm <--- 19" F430 rims are 7.5" @ Front

In this case 235mm is the maximum that should be safely mounted on a 7.5" rim, and yes that's the size on the front rim used on the F430.

PS. It is not me being ok with it, it is the tire manufacturer recommendations of RIM width to TIRE width matching

Just be aware that if you don't go up in size on both front and rear you can slightly effect the handling characteristics at the limit (only a bit as its not such an extreme change). In this case I think its a good thing as IMHO the front end tires washes out too quickly with too much understeer which is frustrating on the track. By the time your really pushing on hard with 235's on the front and 285's on the rear your a tiny bit closer to an oversteer moment than with the stock setup. You do have options to dial out some of this with tire pressures though which you can experiment with to suite your driving style and handling preferences. Depends on how hard you drive. You probably won't even notice if your not driving at 9/10ths..

 

Isn't that the stock front tire size? No they are 225.

 

Great thread! Thanks 360trev!

 

I've been running the Michelin PSS on my F430 with no issues.
225 35 ZR19 and 295 30 ZR19. I have the stock 19" wheels. I have tested the car on the streets with various mannitino settings, and everything is good. I have not been able to break these tires loose so far.

 

I just got some Corsas for my CS wheels. Going to have them mounted next Thursday. Anxious to hear what you think of the RE-11's.

Nate

 

If you can return the corsas do so. If not, see you back here soon.

 

I would refer to this thread:

http://ferrarichat.com/forum/showthread.php?t=339580

And the excellent advice of F430GT. I really wanted the RE-11's but again they were out of stock nationwide so I had to 'settle' for the PSS's.

 

As it is right now the Pilot super sport is the best street tyre you can buy on the market.

Expensive but well worth it.

Fitment sizes are constantly updated by Michelin, as it is completely replaces the PS2 version.

I had a set of new PSS 2 weeks ago and boy, these tyres are amazing.

Well... comparing them with the P Zero corsa I originally had, it is night and day.

So much more grip, ( they need to warm up a bit more when cold) but once up to temperature, they are just stunning!

Also I have noticed that the ride comfort has surprisingly improved too!

I run them on a new set of super light F1 encore 20 inch wheels, that reduce the unsprung mass by 5kg per wheel.
Big change on the handling front.
The car settles faster in corners and you can get on the accelerator earlier than before.

Here is a picture when I fit them at the garage.

Harry, I totally agree. Great tires, I use them myself but like yourself I have wider than stock road car wheel rims. I'm running 8.0" wide front and 10.5" rears so I can safely fit 295mm at the back. What sized rims did you go with and what's the weight of front rims and rear rims in kg's? Very smart looking rims, remind me of the 599 GTO's ones from BBS, 'FI'.

Here's a pic of mine. I run 2 sets now, one set of road car MPSS for general road use and Racing slicks for the track (where they allow them, some days don't!).

Hi Trev,

Yes I am really happy with the results.

The wheels are 20x8.5 and 20x 11.5 at rear.
The weight is 8.2kg the front and 9.5kg the rear.

I have 245/30 at the front and 325/25 at the rear.

The rear tyres are just over the recommended size but the tyre shop owner ( a good friend of mine) guaranteed that it will not cause any issues what so ever and I totally trust him.

You are right, they look very similar to the BBS FI but unfortunately BBS don't do it in a 20 inch yet, I have enquired just before Christmas.
I believe that the BBS are the ultimate, but these EncoreF1's are not too bad either.

 

Wouldn't Bridgestone S-04 Pole Positions be a good choice if RE-11's aren't available, very close rating in the dry, better in the wet, quieter and higher comfort in the comparisons on Tire Rack. I have a set mounted on my spare rims ready to go when spring arrives. No 225's though, you have to go with 235's on the front.

 

No, not a good choice at all.

TireRack rating system is far away from reality, reviews by customers, so far from useful information.

When I look at street tires, I check what the SCCA Solo/ProSolo street tire classes, RedLine TimeAttack street tire classes, autocrossers are using for street tires. These are the guys racing and they would run the fastest tire they can get.

Currently, these are the top tires for dry performance (street tires) in U.S.:

Yokohama ADVAN Neova AD08
Toyo Proxes R1R
Kumho Ecsta XS (noisy and stiff)
Hankook Ventus R-S3 (the fastest of all)
Dunlop Direzza Sport Z1 Star Spec (I like them)
Bridgestone Potenza RE-11 (I like them a lot)

Then, it is down to find what model offer sizes suitable for my car. I personally exclude Kumho from my list, because the Kumho is too loud. Toyo is not made in my car sizes, neither is the Yoko or Dunlop.

So, it is down to two options, Hankook and Bridgestone.

With Bridgestone being a Formula1 tire provider, involved in multiple Motorsports, and supplying tires for Ferrari and Porsche, it is easy to decide between Hankook and Bridgestone.

The Michelin Super Sport doesn't stick as good in dry conditions as the tires above, but it sticks in the rain better than all of them. No one is using the MPSS for National competitive events where street tires are required. I have one set of MPSS for 7 months so far, they are fine as a street tire, great dry grip, great wet grip, very quiet, best summer tire available, but I like the RE-11 so much more, because I have fine tuned the car around them for tire pressures, alignment and what works with them works with the Hoosier (my race tire of choice) so I don't have to change setup. The MPSS uses less camber than the RE11.

For 360, F430, Scuderia, my only tire choices are RE11 and MPSS. The RE11 sticks better than the race compound Pirelli Corsa System (OEM in the Scuderia), while the MPSS offer about the same grip as the Corsa System. The MPSS and RE-11 are long lasting, the Corsa System must be replaced after 48 heat cycles, despite of tread depth.

Be aware that Corsa System, MPSC, Toyo R888, Pirelli Trofeo, Yoko A048 are race compound tires available for street use, but they are not full street tires, these type of tires age quick, and when they age there is barely any grip.
