IS wheels fitment
I believe the IS stock wheels are 17x7 +50 with 215/45/17. Because of the more compact design, getting wheels for the IS300 would be a lot more crucial in order to avoid any unnecessary rubbing. I don't have any wheels on my IS300 at this point but I will do my best. On the IS300, 19" is the biggest you can go. Doing 20" on the IS300 would require tremendous amount of suspension work and in my opinion it's not worth it.
18" Difficulty
18x7.5 +40 18x9 +50 conservative
18x8 +46 18x9 +50 conservative
18x8 +40 18x9 +50 aggressive
18x8 +40 18x9 +55 aggressive
19" Difficulty
19x7.5 +40 19x9 +50 conservative
19x8 +46 19x9 +50 conservative
19x8 +40 19x9 +50 aggressive
19x8 +40 19x9 +45 aggressive
For tires on the IS300 it's even more important because of the tight wheel well setup. The following are the tires I would suggest (and it highly depends on the tire choices too):
Wheel Size Tires
18x7.5 225/40/18
18x8 225/40/18
18x9 255/35/18
19x7.5 225/35/19
19x8 225/35/19
19x9 255/30/19
If you want extreme fitment, the max you can do would be 19x8.5 in the front with 235/35/19 and 19x9.5 rear with 275/30/19. But I won't be disclosing any offset information here for certain reasons.
