Default R 315/45/18 F 295/45/18 or R 305/40/18 F 275/40/18

I plan on getting new rims and tires soon. I want NT05Rs in the rear and NT05s in the front. I just don't know what combination to go with.

With 18x10.5 in the rear, should i run 305/45/18 or 315/40/18 NT05rs?

In the front should i run 18x10.5 with 295/45/18 or 295/35/18 NT05s, or 18x9.5 with 275/40/18 NT05s?

Which setup is the best?

Can I have a 45 height in the rear and a 35-40 height in the front? What are the benefits and drawbacks of doing that? I don't really understand the benefits/drawbacks of smaller/larger tire heights and staggering them :-\

Car will be putting down 700+rwhp

If you try to put a 28 inch tall tire in the front you will probably have rubbing issues.

I would go with:

315/40R18 in the rear
275/40R18 in the front

I am running:

295/40R18 in the rear
275/40R18 in the front

Almost the same setup except the 315 will be 0.63" taller than my 295's. I'll get pics of this set up if you want.

I'll definitely stay away from 28in then thank you!
Pics of that setup would be mic appreciated thank you!
Why was the 315/45 bad for the street? What did you switch to and how is it better?
