non raptor

Might be a dumb question, but what size tires can I fit on stock wheels, at rock ride height. No leveling kit, or lift kit. strictly replacing tires with KO3’s. Looking to do 285/70/R17 to replace the stock 255/70/R17 without having to do a lift.

Hey! I'm buying a regular Ford Ranger XLT 2024 non Raptor, the dealer is supposed to deliver it to me next weekend. I already buy a wheel set from Black Rhino the model is Raid 17"x8.5 offset -18. I'm planing to install a set of 285/70 R17 any idea here if this set will fit with the stock...
