Thanks, Gerald. Without knowing the tolerances I was thinking exactly the same thing.
Back when I was an engineering student I went through the BF Goodrich plant in Kitchener, and I remember the balancing machines that formed the basis of their on-floor QC program. All tires went on, and were trimmed to give a max of 1/2" runout each way. Those that couldn't be trimmed to meet that were scrapped.
What was fascinating was that the engineer leading the tour had them put on a michelin and it just sat there and hummed - no measureable runout at all!
