19x9 45mm offset, square setup in 323ci

Found a very good deal on 19x9 45mm wheels, would I be able to run a square setup in that size in a 323ci with no rubbing and eventually a 2.0" +o- drop? I haven't decided on tire size yet but would like it to be flush. I searched and searched and only found a couple of other threads but mostly about 19x9.5 staggered setup.

Also would someone please dumb down "offset" for me, I know it means how far the wheel sits from the center of the wheel hub, 0 offset being wheel dead center on wheel hub, however, I always get confused as to how that relates in offset numbers, so a 45mm offset would stick out more or less?

TIA for ur comments.

well according to this http://www.rimsntires.com/specs.jsp I should be able to run that setup without any issues, I'd probably stick to same size tires for front and rear for longevity purposes, would appreciate any input, thanks.

Will fit with no rubbing just fine BUT you may have to pub spacers up front to clear the struts. No sure, but maybe.

See link in my sig "will these fit my car?" Offset is explained in there.

You should be ok as far as clearing the fenders. If they say it also clears the struts. You're golden.

Ordered 19x9 Bremmer Kraft BR05 Bright PVD should be here in a few days

That website says after I put in all the info of my current wheels and tires (Beyern Mesh 17") and the new wheels and tires:

"Package is 15 mm (0.6'') closer to suspension/brakes components. Acceptable for most cars."

Will do, now I just have to settle on rubber, 235, 245 or 255, hmmm decisions decisions, I guess I'll just wait till the wheels get here and see what kind of clearance i really have.

I think you can run up to 265/30 at the back, maybe even 275.
And up front I'm not too sure but I think 245s should fit fine, maybe 255 depends on how low it sits or clearance to the struts.

I measured the inside clearance as best I could, at minimum should have .5" clearance but somewhere around 3/4" is what i looked like to me, with 235 tires it will be .4" closer to the strut and with 245 .6" so its gonna be kinda close... i think the offset is too high, shoulda went with 40mm, oh well, it will still work just kinda close for bigger tires.

Without knowing the size and offset of the wheels u have now. I can't calculate if u will have clearance room.

Vs 19x9 ET45. K so 1" wider means 1/2" wider each side that's about 17mm closer to the struts. Then 45mm offset vs 40mm of current set.
17+5mm. Your new rims will sit approximately 22mm closer to the struts.
17" vs 19" puts you 1" higher on the strut. That's 1" closer to the struts spring seat.

Depending on how meaty your tires are, they may or may not cover the lips of the rims. Being 9" wide. I think youd have to fit 265s or 275s up front to do that.

So from the inner edge of the you're current rim edge. The new rims will be 22mm closer to the strut. That's just shy of an inch.
I THINK you will be fine IF THERE IS 1" OR MORE now.
I think youll be fine with 245 tire.

If you don't have the room order a set of 5mm spacers and you still should be ok.
