Hey all, I am new to this forum and I have a question about tire size to ask. I have a stock 2012 Outback 2.5i Premium and I am looking to buy some A/T tires for it. I want to size down to a 15" wheel so that I can get a little meatier of a tire. The tires that are on it currently are sized at 225/60-17 and I am looking at Toyo Open Country A/T iii's that would be 225/75-15. Based on the tire size comparison calculator they would be just slightly bigger, does anybody know if this would be an okay tire to put on my car?
