My 2005 GMC Sierra WT came with 245/70 R17 tires and i have always used this size. The instrument cluster was replaced by the Dealer when the stepper motors started failing. There was an optional (larger) 265/70 R17 tire available. I have wondered if the replacement instrument cluster was calibrated for the larger tire ?? Is there a way to make an adjustment so the speedometer is accurate. Yes, I could change the size of the tire, but wanted to know if it can be changed.
Just joined due to my recent "Check Engine' light codes and was impressed with the diagnostic assistance to others. Will be doing my research and testing in the next few days
