This did not suprise me, but when I got back my milage stayed in the 14-15. I was a bit confused by this. Today I realized that I had put more air in the tires. I went from 28 ish to 36-37 psi. Had a load etc so I wanted to make sure I was coverd. Today I went back to 28ish and I am seeing my milage going up. Only put about 50 miles since I droped the pressure but I am quickly watching my average go up  . If some one else out there has low milage and is runing 18" wheels I would like to see you try this and see what it does.

Can someone please explain how this is possible. I'm running 44lbs in my truck. Problem is i'm only getting 14.2..
Mostly city.. I thought that more air in the tires mean better mileage because of less surface area on the road. Please help i can't seem to get my mileage up there!!
