Default 17x8 tire fitment?

I have looked at a bunch of tire calculators but can't make sense of any. I am going to pick up a set of 17x8" wheels for my 04 wrx. What size tire should I be running for match the original 205/55/16 so I don't have any issues with the speedo and what not?

If you don't want the speedo to be off (and don't want to worry about rolling fenders or rubbing or anything like that) then the 225/45/17 is the closest in size to match the stock 205/55/16 size.

However, since you have 17x8" wheels and you are in a WRX you could actually benefit by going to the 235/40/17 tire size.

235/40/17 would be your best option.

Stock '05-'07 STi's came with 17x8 wheels and 2225/45/17 tyres. The factory had the same issues...
