225/50/R17 205/50/R17

[Stuff]

My vehicle came with 205/50/R17 tires. After seeing a 225/50/R17 tire on my car I kind of liked the look of it. Can I use 225/50/R17 tires and what sort of changes could it cause in terms of gas kilometreage and performance?

The answer to your question is:

In a word, no. Not really a good idea for a bunch of reasons. Will it "work?" Perhaps, but I doubt the factory rim is wide enough for it... I would recommend 225/45R17 instead, but that will have the same problem.

My BMW came with 205-50/17  I checked 225-45/17 sizing and recommended rim size against several tires and bought wider rims for them. I used the oem rims for the winters as there were good choices in winters in 205-50/17

Any idea what the rim width of the stock rims are?  A 225 on a 7" rim would be fine.

As far as gas consumption and performance, your speedometer will read about 3% slow, highway mileage might improve a bit at the expense of city mileage due to the greater rolling diameter and weight.  Acceleration might be dulled a little off the line as well but it's probably not something you would notice.  You should get slightly better grip in the corners and dry braking as well (assuming identical brands of tire).
