Engine load after a lift and up-size of the tires

I'd state the obvious but your speedometer and mpg's from the T4R are off.

Not absolutely sure but I think in a previous post I had mentioned that my speedo was already off by about 2 MPH on the 265s. Once I got the 275s it's nearly accurate based on mobile GPS and speed signs. Thanks for the share.

My 265's were 1.5 mph faster than what I was actually going. 285's were 1 mph slower. That means 275's would be just about spot on. Tested this with GPS
