Jim,
Seems to me the rule of thumb should be to use the same diameter tire
for a spare regarding a posi rear. Might be hard on the clutch pack in a
limited slip to run any distance with mismatched set. A true posi, where
there is no slip wouldn't be able to handle it very long as you'd probably
bust an axle or the differential before long. I would personally get the
same diameter for a spare.--wayne
