RomRaider

Hello, I realize this is not related to ROMRAIDER but I was not sure where to start and am hoping for some ideas from the big brains in this group. I come from 2012+ Wranglers where preprogramming the vehicles for different tire sizes is a pretty easy affair. With newer Subaru's I think the computer knowing the tire size is a pretty important parameter for the ECU in relation to the transmission and safety systems. I have not found anything on if the tire size on these vehicles. I have a 2019 Forester if it matters.

Since this group is familiar with the process, any ideas or hints on where to start to see how this can be done?

Thank you
DAVE
