JB I knew that when I went from bald Brigdstones 245X16 to full tread Michelin 265X16 that I would lost MPG, Remember NASCR runs bald tires for a reason. When you increase tire traction (friction) you hurt the MPG of course going up a size hurts you again. I didn't expect to lose 2 MPG, but oh well I sure look cool now :)
