Tried searching to no avail...

I've installed some 22" aftermarket wheels with OEM size tires, but am coming from OEM 21" wheels.

When in tire settings there is only options for 20 and 21. I do see a special authorization with "other tires" being able to be selected but does not seem to do anything or i'm missing something.

I am wondering

a) does it matter if I use the OEM 21" rear tire size in the settings as the OEM are 315/35/21 and I am using 315/30/22

b) is there a way to access this to add or correct it to 22" as I am assuming if there was OEM 22" wheels installed on the car that option would be available.. Or do I have to have the dealer do it?

Thanks
