So I drive an Acura TL with the SH-AWD system, and have always been careful to keep all four tires the same condition. This system is most of the time operating in FWD, except when the computer tells it to apply torque to the back wheels, and then apportions the torque to the outer tire on curves.
I got an unrepairable puncture right at the shoulder and my current set of tires has about 20k on them, so there is still a lot of life left in them. They are Continental DWS-06 tires, which aren't cheap--around $170 at tire rack and around $200 at a local guy. So I bought one new tire as an emergency replacement so I could get to work.
So now I have three tires that are at half life and a brand new tire. Should I get a second to match the replacement tire so at least both tires on the same "Axle" are the identical diameter and state of wear. Buying three new tires is a no go, I am a married man and the Mrs. would not understand.
Is it necessary to buy tires in pairs or a foursome with this AWD system, I think 99% of the time the front and rear wheels are not locked together while driving, so I doubt there would be much damage to the AWD system by having two newer tires.
Am I over thinking this whole thing and should I just stay with three old and 1 new.
