How do I fit 318/70/17s on a 3gen

Hello I would love some help.

My friend just got a 2023 Ford Bronco Badlands with the Sasquatch package. He decided to take off the stock tires that come with the Sasquatch pack and put on mud tires. (He kept his stock wheels.) He then gave me the 315/70/17 tires.

I currently have a 2 1/2 inch lift on my truck and am running 285/70/17 tires. I plan to use 17-inch wheels with a -12 mm offset and wrap them in the 315/70/17 tires he gave me.

What modifications do I need to make to my truck to fit these tires?

-I also have an overlander tune and a cab mount chop
-I also still have a sway bar and am still running stock upper control arms.

 

6" drop bracket lift or portals would do the job.

 

As mentioned a big lift would do it or cut the fenders and do the body mount relocation, the chop is not enough for 35's/315's. This video is pretty good. But there are many others out there. It will give you an idea though.
