By my calculation your tires are 25.03 inches in diameter. The stock size tires on the 16 inch wheels are 24.87 (some say the RE92 Subaru spec tires are 25.1 inches don't know why they are different than normal RE92s). So you are fine as far as diameter goes. The width may cause rubbing depending on the offset of your wheels with the wagon being more likely to rub than the sedan.
