Need help fellas!
 

I'm Looking into getting new wheels and tires. But I can't decide on which size to go with? I'm either looking at 18's and 33's or 35's. Or goin 20's with 33 or 35's. Just kinda wondering what kinda fuel mileage I'll be looking at between the two. Right now truck is mainly stock besides the comp. has 3.55 gears. Future mods will consist of ats 4000 turbo or industrial phatshaft 62mm, ddp 100's/150's and head studs. Just curious if anyone is running anything close to this setup and what your fuel mileage is? Thanks

i have 16 ars with 315/75s with a 2inch leveling kit id say the 18s with 35s would look good!
