Max tire size, stock setup, 03 1500

[Tombstones]

Wife has an 03 Ram 1500 with the 17" stock rims.

36" wheel well width & height in the front
36" width & 39" height in the rear.

Whats the biggest tire she can get on there with no clearance or rubbing issues?
"as it sits" aka": no lifting or leveling kits.

Height & width of the tire?

Also have fender flares to put on still, if she can get even wider tires that wont rub.

Sorry I dont know enough about tires & have to ask for help.

I put 315/70R17 (35") on my 04 4wd, but I also put a 2" leveling kit with 2" spacers. Tends to rub just a tad.
