Just Installed New Edge With Attitude Monitor In My 06 Ram. I Love It But I Can't Figure Out How To Enter Tire Size Into Computer. The Directions Say That It Should Be In Inches But The Monitor Shows Numbers In The Thousands. I Thought That May Be It Was Showing In Millimeters, So I Entered 4318 (107 Inches). It Saves It But When I Go Back It Shows Me A Negative Reading Of 2311. I Called Edge But They Are Closed On Saturday. If Any Body Has Had This Problem Please Help. Thanks.
