I can't decide weather I want 35s or 37s. What do ya'll have and whats your mpg? So far I have an edge evo and K&N cia on my 5.4L.

Definitely not 37's based on the profile picture.

if your even considering 37's might as well not even worry about MPG. That's something your just gonna have to live with.

X10 to all the comments so far.. I don't see a lift on that truck so 37s WON"T happen. and without a LEVEL kit 35's WON"T happen either.

I get 8.8mpg on the 37's....

11mpg for my 05 5.4 with an edge evo

35's. 11+mpg with Volant CAI. IMO, once you go to 37's, it's time to re gear. I have stock 3.73 gears and it's ok with 35's, but I still get a lot of shifting in and out of overdrive on the highway. 37's would make it a lot worse. Also, the larger you go in tire size, the faster your brakes wear out, stress on diff, tranny, ect.

I assume a lift is also in your future (profile pic)

I know I've been planing on a bds lift for a while, depending on my tire size will decide if I get a 6" or 8"

I really like the Rize 8" lift.
