Thanks, everyone. They are already within pretty close tolerances, as you say.
Changing the subject a bit- our practice wheels, which have only been used for about 1 hour, already show significant scratching; enough that we are concerned about durability at the competition. Do you think that FIRST will have a large stockpile of swap-outs on hand and will require teams to switch who have been practicing to the point where the wheels have additional traction?
We certainly weren't asking this because we want to violate the spirit of the rules regarding wheel modification

; if anything, we wanted to make sure ours were in as close to delivery specs as possible. I'm hoping that there won't be many who come to the competition with worn wheels due to "normal wear" who intended it to be an advantage; I remember there being posts to that effect a couple of weeks ago.
Again, thanks for the input. Good luck to all!
