AWD is great however you need make sure all wheels have roughly the same rolling diameter or you can kill your awd system. For example. If you have 4 really warn tyres and then get a flat and fit the brand new spare and leave it on for too long that wheel will rotate slightly slower than the other three and prematurely wear you AWD system out.
There is an Australian Engineer / YouTube blogger that discussed this some months ago.
