You would decrease the wheel offset by half of the total increase.
30mm/2=-15mm offset added to whatever you currently have.

For example, if you run a zero offset wheel, and you currently have a 275mm wide tire (in theory), hub to tire is 137.5. A 305mm tire, hub to inside edge is 152.5mm. You need to move the hub of the wheel in towards the vehicle (this is -bs) 15mm to locate the inside at the same point.

Keep in mind, this moves the entirety of additional width outboard and can look tacky as ####. Also, different tires have different sidewall profiles, you’re certainly not getting down to 1mm measurements with sidewall width most of the time. Also, wider and with rubber sticking out further is like the worst winter thing you can do.
