Not if you have reset the PSOM on your truck to take in account for the bigger tires, then everything is accounted for, my truck, 5.0 with 33's, msd coil cap and rotor, 9mm ford wires, custom cold ait intake, dual battery, high output alternator, electric fan conversion. I get about 14 city and 16-17 hwy.

I had a 83 F150 4x2 302 Rc Sb with an AOD and 3.55 gears. It had 235x75x15 tires. Dead stock it would get 16 mpg on the highway at about 70 mph. After adding a chin spoiler, a Walker exhaust, and a 4 bbl carb it didn't change a lot but it went much faster. Best ever was 18 at 60 mph.

I have a 91 and 92 f150, same motor, same upgrades, the 91 has 31×10.5's and gets about 8 no matter what where when or why but it's got some serious nutsMy 92 has stock tires and I'm not sure what exactly it gets for mileage but I'd bet it's around double the 91 but doesn't have close to the same Getty up as the 91
