R P275/35R19 26.5" circumference
Diff: 0.3" front bias
Yokohama ADVAN Sport
F: P225/50R18 27.0" circumference
R: P245/45R18 26.7" circumference
Diff: 0.3" front bias
I wonder how this is going to affect all those enthusiasts that were planning to swap there rim/tire combinations from their 350z's. I know it may affect my plans to use the Volks and tires I have as ALL the 350Z's have a rear circumference differencial bias required for there ABS and TCS controls. Definitely have to carefully scrutinize the details of the TCS and ABS systems for the new 370Z.

Glad you noticed this as I've been saying this for ages but no one seems to get it...
My understanding is that the 370 running 19" has an approx sidewall profile equivalent to the 350 running 18" with respect to the factory aspect ratios, but the overall rolling diameter of the 350 is smaller.
245/35/19 on the 350 does not equal 245/40/19 on the 370
