Ok, so here is my theory:
Tire life is dependent on driving habits and psig. I think eco driving habits and higher psig will increase the life of the tire.
Eco driving habits - driving the speed limit, slow accelerating, slow decelerating and no harsh breaking.
Higher psig - Max side wall psig or higher(yet to be determined)
My reasons are based on my personal experience and the comparison of one other, before it was suspision. I have only been able to compare to another FIT Sport 5 speed( I know one is not worthy of proving my theory which is why I suggested the tire thread in my previous post) which happens to have 32k on their tires like me and this person(EL from honda-tech.com) is in need of new tires. EL has used tire pressures ranging from 32-36mpg for the life of the tire. I on the other hand have used 32-36psig for 15K(more like 11K but can't remember) and the rest have seen the range of 40-50psig. I do not need new tires and I have posted pictures of my tires in current condition.
By the way the 60psig does seem to take the corners rather well, better than at 50psig, no skidding.
I really want data not opinions.
Also, for my rotation and balancing I paid a one time fee of $76 dollars and they will rotate and balance as often as I like. $76 dollars to does not seem like much but that is cheaper than the cost of one of the tires and MAY make the tires last longer.
