Something to consider about All Wheel Drive (AWD) vehicles.
Most (I think) have a viscous slip clutch in place of a center differential. The viscous slip clutch is not (usually) intended for a lot of slipping. In normal use, there is a small difference in the rotation rate between the front and rear wheels, hence the need for a center slip clutch. Because of this, both front and rear tires
NEED to be identical as possible in diameter. If you damaged a tire because you ran over some road debris or such, then you NEED to replace
ALL four tires if you have any mileage on the remaining good tires as a new one will be bigger. This assumes you can even find the exact same tires in Boondock USA or wherever you may be.
I have a real 4x4 1988 Toyota pickup (306K miles so far

) and the owner's manual says to not use 4 wheel drive unless you are driving in slippery conditions. This allows the small difference between the rotation rates of the front and rear wheels to be taken up by slipping on the pavement by whichever tire needs it. Otherwise, there would be some tire scrub. The extra stress on the power train isn't any good for it either on dry pavement.
That said, a good friend once told me that it's better to only use 2 wheel drive until you NEED 4 wheel drive since driving along in 4 wheel drive and getting stuck means you're really stuck. Real off road people carry all sorts of gear to extract themselves, winches, anchors, high lift jacks, etc. Also, they usually go in a group for mutual help if necessary.
Another friend had a saying that "4 wheel drive is good for getting stuck
further from the highway".

Truth in that.
