I still have four unmounted265-70 Bridgstones. I am planing to buy 5 Visions from eBay and have shipped to Seattle. Then brought to Kodiak on the barge. I also ended up with a few used 19.5's that one will be my spare. My challenge is I run 225-70 studded in the winter and 265-70 in the summer. I will carry a 9R 19.5 as it will fit in the spare location but will not match either tire. But it will definitely not be too light weight as the stock spare is. I have so far not needed a spare but I do always carry one. I hope this makes sense.
