35s on stock 18 inch rims?

[056ohstroker]

I've done some searching around on here and can't seem to find a straight answer. So I'd like to fit 35s on my 2005 f250 on the stock rims. They are 18 inch rims. It's an fx4 if that matters. I would like to put 35x12.50 tires on but I'm guessing the stock rims are too narrow for that? I was also planning on putting at 2.5 inch ready lift leveling kit on and was wondering if I should also swap out the rear blocks with f350 blocks or not. Thanks for any help. I appreciate it

I think its more so the offset that will make it hit. I know I couldn't clear a 13.5 wide on the stock rim. It would rub on the inside before it could fully turn. Needed more offset on the rims.

Fits fine, rubbed control arms a bit. 2.5" level, 4" rear block. Don't have pics, but the stock 250 blocks sat about 1" ass low.
