They pretty much wear at the same rate, I am not sure how much you will be able to rotate them. If you drive/track enough, you will be going through a set every year. Just save whatever that is left and form a set out of it. I have my rear tires from 2 years ago that I will probably have to use this year in the front. I have said this before. My first set was $1240 installed, second set was $1350, now they are going to be over $1400!
