So I tried to slow it down and let off the accelerator as much as possible, driving between 55-65 MPH and shot up to 48.9 MPG thats with the original tires (88000 miles) just got new Defender 185/60-15 tires on there now and hope my MPG dont drop any, hoping it gets better. My yaris is an AT.

Really good tips here. It almost sounds like an ad for amsoil but I've heard similar results in other threads. But to think that just by switching to amsoil, you've boosted your mpg by 30% is rather impressive.
With my 07 MT Yaris, I consistently get anywhere from 37-40mpg with 30% city driving and 70% highway. Depending on how fast I hit the highway, I can maintain a steady 38+ mpg usually. My hood is slightly up (long story) and someone stole my mirror cover so I know my aerodynamics are horrible. Not only that, I haven't washed the car in a few months...
My sister has the 10 AT Yaris and she tells me that she consistently gets low 30s 80% freeway in hers.
