Replacing flat tire on AWD/4WD Subaru WRX
If I get a flat tire, is there a way to put my car into 2-wheel drive mode to reduce stress on the drivetrain from having a differently-sized spare tire? Would any of y'all recommend investing in a 5th regular sized wheel and tire and rotating that every few months?
If a full sized spare will fit you might want to buy one, I would not rotate it in but you could if you want to. I have used the space saver spare on my 2015 Forester without problem. Do note that Subaru says to drive slow and only for a limited distance. Look in your owners manual for the exact restrictions.
