255/35R19 (Front) & 345/35R19 (Rear) Tires???

Discount tire??

 

How about a 265/30-19 or 275/30-19 front and 345/30-19 rear? Widely available.

Correct, closest rear tire that would still work for OEM system is the 345/30-19. This is the correct size for both the 360/430 and the 456/550/575.

 

I looked into this when I was planning to buy a 360 and then a 430. Getting a wide enough wheel and tire up front would probably require a little creativity,like trimming the fender liners and maybe a bit of fender rolling. Ferrari fitted their competition 360 with a 10" wide front wheel.

 

NF1 and NF2 wheels were explicitly designed for the 360 and are 9in wide in the front. I would NOT go wider then a 255 or 265 in the front, personally. Their max size is typically Front 255/30-19 and Rear 345/30-19:

V12 owners have fitted dozens of 255/35 19 and 345/30 19 Michelin Pilot Super Sport tires to NF2s. For MPS4S the rears would be 355/30 19.

 

I should mention the V12s have equal diameter front and rear tires. You need larger diameter rear tires than front on a 360 or the ABS will act up.

 

355 30 19 is a great option as there are a lot of tires readily available, plus you get the height difference you mention for the ABS.

A 255/30-19 F and 355/30-19 R Combo can be had in both Pilot Sport 4S (which is a better tire then the super sport too)

 

Does anyone in the technical forum know if the 355/30-19 fits the 360/430? The original size was 355/25-19, So it’s not the width I’m concerned about but rather the slight difference in height In a car with OEM ride height

 

I have 345/30/19. A 355/30 might be just a little taller. My car has been lowered so it might work just fine with OEM ride height.
