Agreed. You can run whatever tires you want, all 4 being different even as long as the revs were the same.

I personally would run 2 different sets, each tire has a different characteristic.

Also with all AWD cars. You cant just replace one or 2 tires without the potential to be out of the RPM range and burn that poor transfer case up.
