Wow, I have NEVER had to remove a pulley for a tire change!
I've removed and transplanted pulleys when swapping out wheels though, and ended up re-using the bolts. Same for the disc rotors. But, the book does say to replace them. Your call.
And... 10k and showing cords seems like awfully low mileage. I've been averaging 16-17 thousand miles on my rear E3's and still had some tread left. The trick is to keep the minimum cold tire pressure at 41psi !!!
