Is your IS300 a Sportcross Wagon?

If so, your OE tire sizes are 215/45-17 front, 225/45-17 rear. This is about the same difference from front to rear as your car currently has. If your car is a Sportcross, it would be recommended you keep that difference from front to rear - the car was designed with that in mind, probably due to a little more rear weight distribution...

You could install the same size tire on all 4 wheels, going to a 235/45-17 on the front, although 235/45-17 is a little wide for that wheel. That being said, I run 235/45-17 all around on the standard IS300 wheels which are 7" all around...

Yes rims are off of a sportcross. I dont have one . Theyre on a sedan . I was thinking about running 225/45 all around . Wondering if the stretch from the extra 1/2 of rim would affect height . Assuming it wouldnt be enough to make a differnce

Wish you were closer, I'd love to trade wheels, even plus a little cash...

wheel width has no effect on tire diameter whatsoever...
