You're right, tires are cheaper than a VC.  I guess I'll go shopping this
weekend and see what I can find for the spare.  If I can't find the same
tire, I hate to toss out a set of A/T light truck tires that only have about
11K miles on them.

4/32" is a worn out tire anyway. Test have shown wet traction at that point
is half along with reduced hydroplaning resistance. AT tires can be 15/32"
or more new. One different tire on an axle is not as bad as two. And a new
coupling can be $2K plus installation. Makes matched tires cheap. If your
coupling fails in the excessive aggressive mode than consider a drive shaft
de-coupler.

Wow, that's not much!

So a brand new tire has maybe 12/32" depth on the new tread. If I put on the
same tire worn tire down to say 4/32" tread depth, the difference from the
center of the tire to the tread is 0.25" or 6.4mm.
That's enough to fry my VC?

So how much difference in tire size is considered a mismatch?  I have
27x8.50-14s all around and the spare is 205/70x14. According to my tire
calculator that's a difference of 1.63" between the two.

IIRC, about 3mm is max tolerance before your VC notices and burns up. That
is about $1K to replace.
