Anyone have or try 275/45/20 on stock 20 inch rims?

I need at least 2 tires for my wife's CX9 and looking at the Yokohama Spec tires and Discount Tire shows both the 265 and 275 will work on the stock 20's. The 275 is much cheaper than the 265 plus I think it will fill the width of the 9 much better. Any downside to that size or issue on the CX9?

- reduced MPG by 1-2mpg
- more uneven wear (inner side)
