From Ohio

[tripod]

Hey y'all. My name is Shayne. I'm 24 from Ohio. I drive an 03 Sierra 1500 4x4 Extended cab with a 4.8L. Haven't done many upgrades yet. Went up to 265/75/16 Mastercraft AXTs and added a Spectre CAI. My only issue right now is my MPGs. I'm down in the 12-13 range consistently. I'm a decent mechanic but I'm not sure why it's so bad. I wouldn't think a tire change like that would make that much of an impact. I was at 16-18 consistently before and for awhile after the change. Recently it's dipping down closer to 10. I'm not hard on the throttle most of the time but I do get on it occasionally. Any ideas on what could help other than a tune up? That is coming shortly. Thanks in advance.
