I have never checked my tire pressure since buying the truck new in 2005...I better check it out thanks

 

would be a good idea to start there, I need to check mine as well. My millage is pathetic and makes me feel like something must be broken on my truck. Im getting around 11mpg around town and I drive with a light foot and never gun it off lights. But my tires also may be low so im hoping when I fill them back up my mpg will as well.

 

I run a Roush Cai , Roush offroad cat back, and an edge, on level 2 or 3 with 93 octane 10% eth. and the best I can get is 15.6 avg. on the highway thats behaving myself. I average 14mpg. I do run 285/55/20 g force t/a's .

 

s&b cai dual exaust no mufflers straight through diablo sport predator tuner rollin on 24"s getting about 15 mpg and i like to put a foot in it alot!
