wheels and tires

I just switched to Bronco SAS takeoffs and 35's so looking to sell my OEM wheels/tires. Details below and wheel pics attached. For sale: 4x OEM Beadlock Capable Wheels 4x BFG KO3 (5k miles left) 1x OEM Spare Wheel 1x BFG KO3 (brand new) Located in Western NC

Wondering if anyone knows the right part number for the stock Raptor wheels? The non-beadlock capable ones. Can’t find them on the Ford Parts site. Will they fit a stock Ranger Lariat? Looking to size down to a 255/70/R17 eventually as the stock 255/65/R18 have almost no good tire choices. TIA

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.
