Tires size Q?

Those offsets are slightly aggressive for an IS-F. For tire sizes, to keep your OD correct, the 245/35/19 is correct, however the rear should be able to fit a 295/30/19 just fine. A poster on here, Fig, has fitted a 305/30/19 on a 10" inch wheel.

Technically, 245/35/19 and 285/30/19 have the same overall diameter at 25.8" which means those are the ideal sizes to use. However, you'll have issues with your rear quarter panels due to the offsets of the rear rims.
245/35/19 has the overall diameter of 25.8" and 275/30/19 will have 25.6". The difference in O.D is negligible. If you're set on using 285/30/19, then be prepared to do some fender work. Hope this helps.

You're incorrect:

As I indicated above, the offsets will be a problem.

As stated before, it depends if you are willing to shave the rear fenders or not. If not, sell those wheels and buy wheels with the correct offsets for the ISF...otherwise shave the fenders.
I think you should be able to fit a 245/35R19 on the front no problem with a 38mm offset on a 9 inch wheel...you might even be able to fit a 255/35R19 without rubbing.
You might be able to fit a stock 255/40R19 on a 10 inch wheel with a 40mm offset...even then it would be close. The problem is that is way too aggressive of an offset for the ISF.
If you are willing to shave the rear fenders, I would recommend 245/35R19s in the front and 275/30R19s in the rear…maybe 285/30R19s, but you would probably have to see what fits after you finish trimming.

hey Bao, there's a few things you want to consider here:
a) What type of drop are you doing and with what brand coils in terms of stiffness?
b) Wheel Offset
c) Brand of tires since they vary in shape (ex. Toyo and INVO are more rounded than Yokohama)
d) How much cargo / people you want to be able to drive around with
If you don't want to risk fender damage and still be able to take some people/luggage in the car go on the conservative side with the offset and tire width. Frankly a 275 or 285 tire is not going to make much visual difference however that maybe enough to cause rubbing which you do not want. I have yet to have someone come up and say "damn you went 275 instead of a 295"!
Stock IS-F fitment is:
19x8, +45 on a 225/40 tire up front
19x9, +55 on a 255/35 tire in back
My Advan RS-D which I'm sure you've seen has a perfect flush setup, no fender mods needed and I packed 6 people in the car with luggage on my KWV3's with no problems. Those specs are:
19x8.5, +45
19x9.5, +45
**I know a guy who has just 10mm more aggressive meaning +35 and he had to shave his fenders or he would rub (simply not worth the headache ImO)
gluck!
