I want to be sure I'm getting the right direction sizes for my new wheels.

I purchased new wheels that are 19x8.5 +20 front and 19x10.5 + 27 rear

Right now I have the stock 370z tire sizes for a Sport Touring 245r40 19 front and 275r35 19 rear

The car drives fine but with the smaller wheel in the front and the bigger in the back the tires are now more flush in the front and stretched in the back. I have always noticed that on a Z the front tire seems to be larger in diameter than the rear.

So my question is what tire sizes should can I get to keep VDC satisfied while making both the front tires and rear stretched. Also what is best for VDC is having the larger front tire more important?

Thank you!
