2012 Focus Wheel/Tire Guide

[thenorm]

Are there any difference in brake rotor diameter between the trim levels?
I.e., will the 15" oem wheels fit on a titanium trim car?

In my opinion the best wheel and tire calculator. Tire Calculator

Snow is just around the corner in the northern states, thought this might come in handy.

I think the 15 X 6 is wrong. I think it is 15 X 6-1/2.

Also, it might be that the 16 X 6-1/2 is actually a 16 X 6, strange as that may be. I certainly could be wrong, here. I say this 'cause the 215/55-16 tires that are on an SE, versus the 195/65-15 tires that are on an S -- stick out a whole lot more than a section size difference of 10mm per side!

Note that all of these wheels are about 63.9mm hub bore I think. They are all hub-centric.

The Volvo rims which are 5 X 108 Bolt Circle Diameter (BCD) are 65.1mm hub bore. You need those special hub spacer rings to make up this difference. Those would be pretty darned thin hub spacers! You must have the wheels properly fixed on the hubs!

The original posted wheel sizes are all correct.

.6mm (.023") of play isn't going to make a difference. 28HopUp was successful with Volvo Wheels without spacers. But for the "professional" wheel and tire people will say you will need spacers.

Yup a 15" wheel will fit on all the trims of the '12 Focus (I've got 15" Windstar alloys on my Titanium for winter).

I guess I should chime in!

I have had zero problems with the Volvo XC90 wheels 16x7". Here is the thread I made about them:

http://www.focusfanatics.com/forum/showthread.php?t=259031


The Volvo hub bore IS slightly larger, but the 5x108 lug pattern allows the wheels to be centered once the lug nuts are properly secured. I have had no issues with vibration. But here's the caveot - this car is a commuter vehicle only and isn't driven agressively at all. So I am not putting undo strain on the wheel lugs (IMO) through normal driving. If I was autocrossing the car, then I would use wheels with the correct bore size so the wheel hub bares the corrnering load force.

In terms of determining wheel options, offset is very important, along with bore size (you cannot use a non-factory wheel with a bore size smaller than that on a Focus). But another consideration is maintaining sufficient clearance around your brake calipers. Stock OEM brakes are not massive, but you need to ensure that the spokes of the new wheel will clear the calipers (in most cases you'll be fine I think, but it's still something to consider).

Can you give me a sense for where / what your source is?

I am principally talking about the steel wheels. I found some info from a wheel supplier, that suggests that there is a 15 X 6 and a 15 X 6-1/2 out there -- as in stock / OEM wheels. Likewise re the 16" steel.

In talking with a professional wheel / tire shop -- and the principal who I consider to be a pretty decent source of accurate info -- he said go out of your way to stay with the stock ET value. He had had direct experience, decreasing the ET value (i.e. decreasing the back-set) on his shop vehicle. It went from tracking really well, to a circumstance of very poor steering.

If that's the case, then short of having wheels custom-built, we aren't going to find anything in the aftermarket for our cars. The offset values on OEM wheels are at just about the highest numbers possible, but most aftermarket manufacturers seem to go no higher than 45 or so on 5x108 wheels.

Hmm, I see I could 'borrow' my father's wheels from his Continental to change things up.
