2010 Ford Ranger tire size?

I know, this isnt a ford ranger forum but figured why not, seems like theres more traffic here than the ranger forums ive browsed....
Figured maybe you guys have been there before getting your tacos, or have friends & actually know, can share some insight or suggestions...


Been chewing on trying to make a decision for a bit, would love some insight that would push me one direction or another....
Truck is 2010 single cab 2wd 4 cylinder ranger.
I installed 4" Wulf spindles in the front only, not touching the back....
This truck will never see the dirt, just my kids first vehicle that will hopefully last him till he gets established...
Has 4:10 gears...

Im all over the place inregards to tire size,
I think I want to keep tires in a P metric just to keep weight down.
Looking at Cooper Discovers at3 in a 265 75 15 which is a 31'ish....
Then part of me says go with a smaller tire & keep things easy on the truck like a 30", maybe a 235 75 15,
Not sure how size of a 235 75 15 actually compares to a 30 9.5 15...

Included a pic of a 2010 ranger with 31 10.5 15
& gray ranger with 30 9.5 15

Some insight, thoughts, suggestion to help me un-fk me spiraling & closer to making a decision?
Thanks....
