What is speedo error from tire change?
Just put on a set of BFG Mud Terrain 285 75 16 on my 98 150 4X4 extended cab. I believe original equipment was 245'S and would like to know the percentage of speedometer error so I can calculate gas mileage. Really like the tire. Much quieter that I would have thought. Thanks Ron
