Wheel fitment help.

[NeverOddOrEven]

I just got my F30 this past weekend which I ordered 8 weeks ago. It's great and I love it. I've also had some wheels/tires that I was going to throw on it but it turns out they were staggered and I bought the wrong size tires

So anyway, the specs are this:
18x8.5J fronts
18x9.5J rears

The guys at Discount Tire didn't have the F30 in their system so they weren't positive what size tires would fit in the wheel wells. Here are their suggestions, but they weren't completely sure:

235 or 245/40/18 Fronts
225 or 265/35/18 Rears

Does anybody know what the official specs are for the F30--as in, which tires will fit period, or fit without sticking out to much, etc?

Any help is appreciated!

235 is the widest I've seen on the front. 265 is not a problem on the rear. Sounds like the offsets of the wheels are wrong, not the tires, if they're sticking out.

Yeah, I went with these wheels: http://www.fujicorporation.com/img/u...ew/14119_2.jpg I've never seen them on an F30 so I guess I'll be the first.

[tim330i]

Do you know the offsets?

[NeverOddOrEven]

Not off the top of my head--are they printed somewhere on the wheels?

[tim330i]

Sometimes they are. Did you just buy the wheels? If you link us to where you got them I'd think it would list the offsets there.

Got them here: http://cgi.ebay.com/ws/eBayISAPI.dll...ht_3158wt_1347

37 fronts
33 rears

TireRack shows for the 2013 BMW 328i M Sport Line with staggered wheels:

225/45/18 F
245/40/18 R

Yea, that is way too aggressive an offset for the rear. We're running VMR V718s in 19x8.5 ET35 fronts and 19x9.5 ET45 rear on the Project 328i.

http://www.velocitymotoring.com/wheels_v718.html

Tires are 235/40/19 front and 275/35/19 rear.

You really should just sell those and get something that fits the F30. I bet ModBargains or one of our other sponsors can get you the same wheels in the right offset.

EDIT - Stagger is just fine, you just have the wrong offset

Tim

[NeverOddOrEven]

I see. So if I were to go ahead and mount the rears on, say, 255s, would they fit or would the calipers clip? Would it be safer to go with a wider tire instead?

I don't really have the time or energy to sell the wheels and get new ones, so I want to weigh my options with mounting them anyway in terms of any wheel damage or safety issues...

[tim330i]

It's not an issue of tires. The wheels will stick out, you're 12mm, or about half an inch further out then what we're running. It won't clip on the calipers, you're going the other way. It will likely hit on the fender sheet metal. Thinner tires might help with clearance issues, but how much is doing to depend on the tires. Different brands have different shoulder profiles.

I know this isn't what you were hoping for NeverOddOrEven but new wheels is really the best (only?) solution.

Tim

[NeverOddOrEven]

Yes, I've come to terms with having to sell my existing wheels. I've been debating with these two:

18x8 ET 37
Stick out 4mm

or

18x8.5 ET 35
Stick out 14 mm

Which one would be more ideal?

[tim330i]

Sorry that you had to go this way around but I'm happy you're getting the right wheels for your F30. I would want 8.5" wheels and ET35 looks good on this car -

Those are 19x8.5 but going a size down to 18x8.5 won't effect the offsets.

[NeverOddOrEven]

On that guy's original post he says he used 235 in the front and 255 in the back. Another newb question, but will the extra width go towards the inside the of the car? So suppose he got 235s in the back as well, would the outside side wall be at the same position as the 255s?

[tim330i]

It would be split, the tire is going to naturally center over the tire.
