Yup, finally hit 35 MPG today. At the beginning of this tank, I aired tires up from 32 to 40 psi. I was thinking it would make for a harsh ride and such, but it's actually a little smoother and cornering has really improved.

But one thing I didn't expect was the increase in MPG!

32 PSI same trip to/from work @ 60 MPH = 31.90 MPG
40 PSI same trip to/from work @ 60 MPH = 34.97 MPG
