another flat tire thread

[Brady Moffatt]

Hi All,

Last night, the back right tire of my 4kq went flat due to an invisible
sharp thingy that appeared, cut the tire between the tread blocks, and
disappeared. Unfortunately, I had no choice but to drive on it for a couple
of kilometers before I put on the donut spare. The tire is toast, which is
sad because it was a studded Hakka2 with 10/32" tread left.

Anyways, I got a replacement tire installed in under 15 minutes under the
road hazard warranty. Amazing service, and I didn't have the receipt for the
tires either. (Pneus Premier Choix in Ste. Rose for Montrealers)

So, now I have a 10/32" tread on the back left, and a 13/32" tread on the
back right. The tire guy says that 3/32" difference is the max allowable on
AWD. I tried locking the diffs with the new tire on. Worked without a hitch.
Car feels very stable with its usual huge amount of grip.

Finally, here's my question: Should I swap the backs and fronts so that I
have even wear on the rears, and have the discrepancy on the
always-open-diff front?

Cheers,
Brady
