Will a 245/40/18 square setup with 18x8 +40mm work on an IS 350?

 

i tried the IS350 rear wheel with 255/40/18 with 50 mm offset and it fit fine but only have about 1 or 2 mm clearance for the tire not to touch the arm control, I think that specs work fine

I can't speak to 245/40R18 up front, though I'm sure others have tried it.

For myself I run a 245/40R17 square setup and have had no issues with rubbing or clearance. That said, I am on the factory sport suspension springs and so am not really lowered.

245/45R17 should work fine with the right offset.
In the next few days I'm gonna try ISF size tires 225/40R19 and 255/35R19. Several members installed ISF wheels and tires with success on their ISX50.

 

I’m at stock height as well. I found these wheels on Marketplace for real cheap, just don’t know if they’ll fit or not.
