Sorry guys. My email notification wasnt working, good thing I checked back. My tire size is 225/45/18's. Just started driving like 60 miles to work and started noticing the rpm's were sucking the gas and the prices are going up so you start paying attention to eveything at that point. lol. i have been doing the same..hitting the cruise at 60 mph..but Its SO SLOOOW. I think we need a better OD gear if you ask me. Thanks for all of your help. Jet

Not sure how the G measures speed, but if it's measured from the transmission, going with taller or shorter tires won't change the correlation between RPM and speed on your tach and speedometer. However, changing tire size will have an impact on your actual speed vs. your indicated speed.
That said, my 06 AT cruises at 2800@70, and 3400@80.
