For the folks that say they are loosing gas mileage when going to a taller tire should keep this in mind...If you don't change the speedo gear to match the new tires your speedometer will be reading slower than you are actually going. This will cause the odo to show less miles than you are actually driving. This will cause your mpg to be artificially low. Your mileage may not be as bad as you think.
