Hi: First one should never place different size tires on an AWD vehicle. Who sold you the tires and put them on the vehicle? I do, however, strongly suggest that you take the vehicle to a dealership. The difference in tire size may have caused problems in the drive line. Allow the dealership to diagnose the problem, and then you will know how to persue the problem (tire shop or repair facility).
