Discount tire shows the 245/40/17 will fit without issue.

245 is pretty wide for the stock 7" wide wheel, it's not recommended, just from the wheel/tire combo side of things.

If you can stick your finger between the tire and the strut, you should be good.

Remember, going to a 245 only adds 10mm of extra width on either side. If you get some wide summer performace tires, it might be a little more.

Problem with switching to 245 wide is that you'll likely want to drop your sidewall from 45 to 40 at the same time. 45 handles widths better than 40. 245/40/17 needs 17x8" where 225/45/17 needs a 17x7" rim. Increasing your tire width that much and dropping the sidewall means you need a substantially wider rim.

225/45/17 = 17x7.0" min
245/45/17 = 17x7.5" min
225/40/17 = 17x7.5" min
245/40/17 = 17x8.0" min

09 WRX stock rim is 17x7.0"
