Largest tire size on stock suspension??

[RamGuy84]

Im thinking it would be the same as the previous ones. 295/60/20 works I know for sure. 295/65/20 would probably work with a slight rub on some turns., but idk.

Howdy,
Stock 285/60R20 with factory Firestone TransForce A/T tires are like highway tires here.

I am looking for options on sizes fitment. Either way, I am getting new tires with some meat.
