Tire Size for OEM Wheels

Blue-Z

Hello Everyone,

I looked through the web and I wasn't able to find the answer I am looking for or pictures of the setup. I'm reaching out to the members of this forum for some insight before making a purchase.

I have a 2012 370z Base Coupe. The OEM wheel/tire is 225/50r18x8 (front) and 245/45r18x9 (rear). Stock Suspension.

I have upsized the tires to 245/45r18x8 front and 275/40r18x9 rear. I have no rubbing, speedometer, or VDC issues with this size. (Current tire FireHawk Indy 500)

However, it's time for new tires and I'm trying to decide what option is best for street performance dry/wet without compromising fitment, VDC issues, or revs per mile.

What are your opinions if I chose to stay with 245/45 fronts and change the rear to 265/45? Will this rear tire size create problems in terms of revs/mile or acceleration? The reason I am moving from 275/40 in the rear to 265/45 is in hopes of closing the gap between the top of the tire and the fender well and match the front tire sidewall.

Please post pictures if you have this setup or chime in if you have some insight, I would greatly appreciate it.

Below are links I used to help me research. They provide educational knowledge.

p.s - I will post my current setup 245/45r18x8 and 275/40r18x9 and the new size we talk about/stay with the same size to help build this thread for future owners.

Respectfully,
