I've got 13,000 miles on my '07 6 speed now, the rear tires appear to be wearing evenly....but, both the fronts are wearing much more on the outside than the inside. Could this be because I take those 40-50 mph curving off ramps at 70-75 mph....or do you think I need to have more "toe-out" ?

Can you think of any reason I shouldn't have the front tires taken off & reversed.....so the deeper tread is on the outside....I could even keep them going in the same direction (even though I don't think they are unidirectional) by swapping the right for the left while going inside out?
