1998 K2500, ECLB, Auto, 4:10, 265 75 16.
Latest results are 18 MPG combined.
Combined is roughly 60% highway, 40% city. Highway speeds not above 100 Kph, windows up, AC on.
Just switched rims to a set of PY0's from a later 2500HD. Requires far less throttle for same rate of acceleration and lighter touch highway to maintain speed.
Weights:
steel wheels scaled at 34 lbs each
PY0's scaled at 17 lbs each
That's 50% savings at each wheel in rolling mass.
Hoping for a small return on the less rolling mass. Would be overjoyed with even 1 mpg increase.
