Gas Mileage!?!?!?!?!

Hey guys and gals. I own a 1992 f-150 wit a 5 liter 302. It has dual exhaust and K&N. I currently have 235/75/15 tires and im getting new 15x8 inch rims and with 32x11.5x15 mudtires. Will this hurt my gas mileage really bad or will it not cahnge it too too much. If any one has this same sort of set up or close id like to hear what you get for mileage. I think i get around 15 miles to the gallon right now. But less at the moment cuz its cold winter hear and i let it warm up good.

Thanks hope to hear from you soon.

I had your truck with 33"-12.5" and I was about 12 mpg. I had a manual too though, and no air flow mod's. That truck was worthless in 5th gear, and I even had the 3.55 rear.
