With most AWD cars and trucks you want to replace all the tires at the same time because of the rolling diameter is different therefore causing binding in the t-case, at least thats what I have been told. how much of a size differance is in the new tires complaired to the old.

all 4 tires are 100% identical. I read on the Explorer Forums that having different sizes on the front and the rear will cause this problem, as the the “system” will notice that the front axles are turning at a different rate than the back ones, and use the AWD system to compensate/correct that. That makes perfect sense to me, but all of my tires are the same size.
I believe the old ones were 245/65/16 and the new ones are 235/84/16. the way the dealer was talking, they said if you have 4 tires that are half worn, and you need to replace one (due to a blowout or whatever) then you need to replace all of them because that minor difference in the the tread of the new tire to the other half worn other 3 is enough to fuck up the system. Im sorry, but that sounds so rediculous to me, and i have a hard time buying it.
