    Correct me if I am wrong but surely the HGTE came out with a softer tyre than a standard 599.

    I think it was P Zero Corsa System compound in the normal P Zero tread pattern.

    I am running Michelin Pilot SPort Cup 2 tyres on HGTE rims 245 35 20 at the front and rears are 325 30 20. No problems with this set up and the wider rear tyre has improved rear traction on acceleration and cornering. Excellent tyres but they do wear quickly and are not to be used in the wet.

    Those tires are huge! Do they cause any problems with the e diff and traction control? I have GTO rims on my '08 GTB and my dealer will not put the GTO tires on (285 front, 315 rear) as they say it will upset the e diff and potentially be unsafe. The front 255's look pathetic on the GTO rim, as the rim is wider, though the 305 is less noticeable on the rear GTO rim in terms of width mismatch.

    Tyre width and rim diameter will NEVER cause any electronic issues. There's only one way you can get a problem, and that is if the wheel speed sensor gets confused. This means you need to keep the front to rear diameter bias within +/- 3% of OE. The car will never know how large the tyre diameter is, can't know the rim diameter, nor will it know about the tyre width. The only thing the car systems can know, is whether the front and rear wheels spin within a certain margin in relation to each other. If they keep the OE front to rear diameter difference %, you can make the tyres as wide as you like, the rim diameter the size of wagon wheels and the rubber the diameter of monster truck tyres. Just keep that front to rear diameter in check.

    If your dealer, tech or know-it-all car buddy tells you anything else, roll your eyes and change the subject.

    I have a 2009 599 GTB. After a nationwide search I can't find the MPSS in 305/35/20's. I'm interested in following up with the suggestion to use 315/35/20. It appears that this size would change the speedo read by .5% - 1%. Quite insignificant, but I wanted to know if you're aware of anything else to consider. Also, since this size is manufactured for various vehicles, it's profile is actually different for different cars. Do you know which would be the ideal choice for Ferrari?

    Thanks!

    I just put on MPS4S in 315/35 and 245/35. It is what I was running before in MPSS and there are no issues. Got them from TireRack in 2 days and the date codes are only about 6 months old.

    Thanks skidkid for confirming that. Did you happen to order by size alone, or did you specify a Ferrari specific tire?

    Talk to someone at the Tire Rack. I just ordered a set of 255/35/20 fr & 315/25/20 rear for my /07 599 two nights ago. The rears will be in on 3/26/21 and I’ll pick them up the following weekend/have them install. (I’m in Indiana). They have several coming in after a nationwide temp shortage of the tires.......

    That was an old post, I would definitely recommend the MPS4S now, and they are available in 305/35 20 now, although no problem fitting GTO size 315/35 20. They are nowhere near large enough to bother the ABS, which freaks out somewhere around 4-5% difference from stock front to rear diameter differential.

    My 575M has MPS4S tires.

    You went 315/25 and 255 up front? Why that selection? It looks a bit odd.

    One size up on both fronts and rears, I assume. Here is hoping he meant 315/35 and not 315/25 or the ABS is not going to be happy.

    I just ordered them last Thursday and they were at my mechanic on Saturday. As I recall, the rears are a Ferrari spec and the fronts are not. Honestly, I think most are WAY over thinking this. Yea, if I am pushing 99% on a track I might care but you won't even be able to tell the difference on the roads. The primary difference is tread depth/wear rating.

    But front stock is a 235 as I recall. 245 is one up as is 315. 255 would be 2 up.

    I have the GTO wheels and tires 285/315 k1 and no issue with the car. I had 255 before and I agree they look too small. The added grip is also a benefit here.

    That is the best choice for the Monolitic and HGTE rims.

    I'm just not a fan of Pirelli tires for the 599, Michelin is on another level IMO, Pilot Sport4S is the choice.

    Just ordered a couple of new rears for our Euro trip in May to the South of France. 315/35/R20 MPSS K spec from Cam Skill in the UK, £540, + £50 off from Michelin so £500 delivered and I'll get my local guy to fit them before we head off.

    Currently have 3mm left on the rears and 5 on the fronts.

    I have just installed Michelin Pilot Sport 4S, 245/35/20 K2 front and 315/35/20 K1 rear on Challenge wheels.
    Many posts suggesting 255 front tyre should be installed on minimum 8.5J rim and not on 8J rim, but don't we have similar situation rear, where 315 is installed on 11J rim instead of minimum recommended 11.5J ? Image Unavailable, Please Login

    Not sure where you got that info, but the recommended wheel widths for the 245/35 20s are 8-9.5" and for the 315/35 20s are 10.5-12.5", so you are fine.

    It looks fabulous! Very similar to mine. Is your car lowered?
