Ok, so I currently have some 17x8.25 +35 offset wheels that I am going to be putting on my 2012 iTouring hatchback. I'm running into a few problems though.

1) When I initially bought the wheels, last month, I did a fair amount of research and figure out that these would fit fine. Now I am not so sure, so I don't know if I will need spacers to get them flush. As stated before, they are 8.25 inches wide with a +35 offset

2) What size tires should I get to get smallish sidewalls, not too much stretch, and a summer performance tire? I was thinking 215_40R17 size tires but I'm nopt sure how they will look on a 8.25" wide wheel.

3) I need new bolts to put on the wheels because the stock ones won't work, where can I buy some?

Sorry if this seems noobish, I just need help. Please, and thanks to anyone that can help me figure something out.

Those tires on that rim are going to be more than an inch smaller in diameter than stock, so you are enhancing your wheel gap by that amount, as well as creating a speedo difference of 4.5%.

The advisable tire for that rim would probably be 205/50, 215/45 or 225/45.

If you specifically want a 40 side wall, you should go with an 18" wheel.

I'm fairly open-minded on the size of the tire, I just don't want anything too beefy, but I also don't want to throw off my speedometer. Do you know how 225/45 tires would look on a wheel only 8.25 inches wide?

225 tires are recommended for rims between 6.5" and 8.5". Unless you are looking for the stretched look 225 is fine. I don't like stretched tires so IMO 225 or 235 is the sweet spot for a 8.25" wide wheel.

Ok, thank you so much! Will the sidewalls on a 225/45 look too big though? Because I know that with 225/40 the sidewalls are 40% of the tire width, so the 225/45 would be 5% larger on the sidewalls.

Click on the mods link in my signature and scroll down...I have several pics from different angles and I run 225/45. If that is too much sidewall for you, you need to upgrade your wheels to 18s. Your wheel gap will look immense if you run 225/40/17.

Thank you so much!! Those look perfect; I'm definitely going with 225/45 tires.

Just an FYI, I was mainly describing the cons of going with a 40 sidewall tire on a 17" wheel with respect to overall diameter. Your offset of +35 brings about the issue of whether you will rub and whether you will need a fender roll in the back. I recommend you read color0's Wheel Fitment Guide before proceeding.

so then I can run a 215/45/17 on my 3? I thought it was either 205/50 or 225/45 for speedometer to be within range. I guess I learned something new...What looks best on a 17 with 7.5 wide rim? I'm debating on both, well now 3 according to you. My offset will be 42 (will I rub or need extra work?).

Didn't mean to thread jack :cheesy:

It's all relative. If your stock wheel is 205/55/16 then your stock diameter is 24.9"

225/45/17 is 25.0"
205/50/17 is 25.1"
215/45/17 is 24.6"

So yes, 225/45/17 and 205/50/17 are closer to stock 205/55/16 than 215/45/17, but the difference isn't huge. For example a 24.6" diameter is 0.3" from 24.9" which amounts to a 1% difference is speedo measurements.

OP's main concern was sidewall height so I was just pointing out more options.
