    I think what's throwing us off is that rear wheel, need a diff angle but looks like a larger offset pushing them closer to fender would not make them look undersized, perhaps again it's the angle.

    The ratios may be close but I doubt they are exact. I'm not sure what the threshold is where the ratios become an issue... But you're probably fine as long as you're very close. I would imagine tire pressure variance could account for some differences so a tenth of an inch shouldn't hurt

    You've got me nervous, let me check if my HRE guys were correct.

    I wouldn't be too nervous at this point...you can check the tire diameter on TireRack and hopefully they have measurements with your wheel sizes

    Thank you
    I went on tirerack site and that's what I've found out about tire diameters:

    Original Pirellis P Zero equipped Huracan

    245/30ZR20 = 25.8"
    305/30ZR20 = 27.2"

    Michelins
    245/35ZR19 = 25.8"
    305/35ZR19 =27.4"

    It looks like fronts are exactly the same and the backs are within 1%. You think I'm okay ?

    Wait ... that's not all. Reading all reviews comparing Pirellis to Michelins. Pirellis got destroyed.
    Me say notin, but Ouch!!!

    You're fine, didn't mean to scare you

    I think low tire pressure could account for more than .2"

    I've seen the same on reviews and typically I opt for Michelins myself...but i figured burn through the OEM rubber first.
