Help!!! Ur opinions needed!

[WV98YFM350]

Got my 25" tires on the way. So I need to know where to start with gearing. Should I go down in both sprockets or just the front? or just the back? or leave them alone? HELP!

I'd start with 12/40 gearing then adjust rear as needed

11/40 imo

11/40 for sure.
