Hey I'm schedualed to run Friday I believe.  I'd be willing to help out.  Let me check my ticket to make sure.

Question, I'm running 42x15's and I do NOT have a spare.  I've been fighting this issue for weeks trying to figure out what to do.  Who the hell carries a 42" spare tire? Anyway, are the people in charge going to let me run this trek without a spare?
Thanks,
Tom Bentzen

They are not supposed to.  There is a safety check at the trail head.  They check for about 10 items, and a spare is on the list.  Must be fairly close to the size that you are running (within an inch or 2).  They might let it slide, if you are with a buddy  and he has a spare of the correct size.  Call or email cal4wheel for verification.
