Oh and congrats and welcome.
Noticed this in another tread about tires. I have 305 tires and only carry the stock 275 as a spare. I figured it wouldn't be ideal on the drive train but better than nothing and wouldn't affect things too much for a limp home. Why will an undersized spare not work with the VC and is it a 97 thing? And what if I just lock the center diff if I have to run the smaller spare?
