Hi everyone,

I got a 2023 IS 350 with the 19in BBS 19s. After some research I've found it has the following tire sizes/diameters:
235/40ZR19 92Y front axle = 26.4x9.3R19 Overall Diameter
265/35ZR19 94Y rear axle = 26.3x10.4R19 Overall Diameter

I've looked around and found some earlier 3is fitement guides, however, these didnt quite line up. What would be the tallest tire dimensions one could run on a 19in wheel without rubbing? I don't mind if the odo is out a bit, the roads are quite bad where I am, so anything to improve ride quality is a huge benefit.

Any links or reccomendations are appreciated!
