Front tire size
Getting ready to order Michelin PS2's for my new IForged 18x9.5 fronts and 19x11 rears. Will a 285/30 fit ok on the fronts or should I stay with 265 or 275 / 35's? Is a 30 section to match the rears ok or is it too low?
I'll go with 305/30 on the rears.

5 series sidewall difference won't look bad at all. That is how the factory did it with the 40 series front and 35 series rear.
I think a 275/35 is a better pair then 285/30 which wouldn't be that tall.
275/35 - 25.6"
305/30 - 26.2"
That is a nice stagger. A 285/30 is only 24.7" tall so it wouldn't match the rear too well. A 265/35 is 25.3" which be an even closer match to the factory stagger.
OEM was
265/40 - 25.3"
295/35 - 26.1"

Stevo,
I think you're probably right. But I just assumed that keeping the same aspect ratio would result in a side view looking equal front to rear. I didn't consider the actual diameter of the tires in the equation which I should have. Thanks for the info and will stay with the 275x35 and 305x30's.

I have the exact wheel combo as you. I just got Nitto Invos from Discount, for about half the price of PS2s, and couldn't be happier. I got 265-35/18s for the front @ 25.3" tall, and 325-30/19s on the rear @ 26.3" tall. No fitment issues.

I've basically gone nuts looking at tire brands; Goodyear, Michelin, Yokohama, Hankook, Toyo, Nitto's, Firestone. The reason I've sorta decided on Michelin is that John @ Autobuffs quoted me a very low price on the Michelin's, I purchased the wheels thru him, and I know a couple of club members that like them. Not to say that there aren't other good choices, I liked the Yokohama Advan-Neova's but at some point just gotta decide and John's price on the Michelin's is hard to beat! Too many choices for my feeble mind! But I think I've nailed down the sizes; 275x35's and 305x30's.

I run the 265/35-18 PS2 on my car. It is a match for the stock 17" diameter tire and keeps the right proportion to the rears for computer accuracy. It looks great compared to the larger rears you will have.
