ORIGINAL: anteyeiabazele [:@] Hey guys someone told me that when changing wheel size u have to change a gear in the audometer is htat true? On older cars thats how you adjusted the speedo....nowadays its all controlled by your ECU, so you can just reprogram it. Its all based on the diameter of your tire, so usually what happens is when you put on a larger rim (ie a 20 to replace an 18) you also do a lower profile tire (ie a 35 vice a 55) and your actual tire diameter still stays the same.
