If you want the opinion of someone who works in the tire industry I work at Les Schwab. It's Subarus and Fords that are really sensitive to mismatched tires but for our liabilities sake we won't install mismatched brands/ models on AWD vehicles period and if the tires are the same make and model they need to be within 2/32 of an inch tread depth on all 4 to be acceptable for application. Hope this helps
