Dropping MPG

[rayt]

I'm down to 10.6 mpg combined highway/local. Granted this is NYC, and i have a heavy foot. I think this is pretty bad. was at 11.5 or higher half a year ago.
I am level lifted with rancho ready lift, running stock 17" wheels with good year all terrain adventure LT-C Tires.

On the same note, i get 12.8mpg on my Ram rebel that has tires that are 1" bigger and LT-E tires.

Am i due for something like spark plugs? or anything like that. I'm at 35k miles on my 2011.

At 35K you shouldn't be due for anything except perhaps an air filter (depending on when you last changed it). I get between 15.5-16.2 mpg combined in my EL running the stock Pirellis, but I can easily get that down in the 13s by driving like a bat out of hell (as I sometimes do).

I cleaned my MAF and did a computer reset (unhooked the batt and touched the cables to each other). I think it's still re-learning (anyone know how long that takes?) but I'm up to 14 ish on the readout just running local...I do drive nice tho LOL
