Thanks. Just to confirm, you and I have the exact same setup, right?

Apex ARC-8 sized 18x8.5" ET38 with 245/40/R18 tires up front and the 18x9.5" ET22 with 275/35/R18 tires in the rear.

Brand new fender liners and yes, slight rub on the access panels at full lock with those 245/40/R18 tires up front.

Hankook Ventus V12 vs. Continental Sport Tires

Hey everyone. I'm new to the thread and just bought a 2006 Z4 M Roadster. It's got ~50000mi on it. I need to replace the tires on front soon and probably within the year also replace the rear tires. Wondering about opinion of Continental Extreme Contact vs Hankook Ventus V12 mainly in performance category?

Very well worn Continentals on the front that need replaced soon, and Hankook Ventus V12 on the rear. Here are the specs.
Front - 245 35 R19
Rear - 275 30 R19 (looks like previous owner had the rear Hankooks put on at 41000mi 4/16/16)

I've got aftermarket Axis wheels.
Thanks all

Nice wheels but are you sure on that rear width/offset?

Not sure if its the angle of the photos or camber setting etc... but that rear does not look remotely close to those specs?

It's what was engraved on the centers offset wise from Hamann. The width I did actually measure and it's 10". But actually an interesting point to be honest as the barrels could have been changed I guess and I wouldn't have a clue ........ unless I measured them myself............. which I didn't. Maybe when I'm bored one day I will take the time to actually remeasure them. But I did buy them used so completely unsure about the history.

What I do know is that they fit nicely without any modification.

I am considering spicing up the wheel department a bit!

Is anyone running 19 inch BBS CH-R wheels on their Z4M? I could only find two pictures and so far I am liking what I see!

NickyC had a set on his, I recall they looked very nice (especially after he removed the chrome ring) but the pictures are no longer in the thread.

Just saw my name posted, I'm happy to post some pics again of my baby which I miss oh so much. I never wanted to sell her but it was time to move on, please find some pics of her with the 19" BBS CH-Rs (chrome ring is a MUST removal imho). I also included a few pictures of my new car with 20" HRE FlowForms with some nice 295s on the rear!

Hope everybody is doing well!!

Yessir, looks just as good as I remembered! Quite a beauty, if I had kept my Imola roadie I'd have loved to have it just like that.

Your new baby is nice too

Thanks NickyC and Rockstar93! I like the look of those. Do you happen to remember the sizes and are you using any spacers? Seems like a nice alternative to the CSL's. I am considering brilliant silver on Interlagos blue.

Thanks very much V3.2mc. Those CH's already look good and I like the CH-R's even more. The central portion is a bit slimmer which makes it look lighter.

These are the wheels I use to store the car (summer wheels off my E90 M3), and while the tire sizes aren't ideal the wheel specs make for a very nice, aggressive look. I've seen a couple other members run these 219M or the very similar 260M wheels on their E85/86's.

Contemplating turning these into a dedicated set of track wheels/tires (which also means my E90M gets a new set of shoes) along with some more front camber.

Specs for those that don't know:
BMW Style 219M - by BBS
F: 18x8.5" ET29 + 245/40R18
R: 18x9.5" ET23 + 265/40R18

With these tires I do rub slightly on full lock or over bumps, but I'm also within factory camber specs but lowered on KW v3's.

Hi all, just picked up my 06 Z4M over the weekend, been looking at wheels.
Having read through an exhaustive offset and width guide, would like to see if anyone would have a clue whether it will fit with rolling hopefully without needing a pull

18x9.5 +22 front, 245/40-18
18x10.5 +23 rear, 275/35-18
I have no issue with rolling, even flat rolling the fenders

Car will go on TCK Double adjustables, I don't slam my cars, its going to be a functional low.

Your help is much appreciated.

Excellent thread - 22 pages of information and inspiration 👍

I notice that square setups are mentioned only a few times. On the E82 1-series forums, a square setup (wheels and tyres) was very popular and apparently helped get rid of the understeer those cars suffer from.

So, why aren’t square setups as popular for the Z4 Ms?

Secondly, does the collective experience of users offer any guides for what 17 inch wheels can/should fit?

Thanks!

I run a square set up for the track and staggered on the street. The Square set allows you rotate to get more life out of the tires, but I also have much more camber on the front to accommodate the tire size. I prefer the square set up on the track as the car handles much better, but the 19" HRE's look awesome on the car.

Staggered - 9.5" 245/35/19 front and 10" 275/30/19 on the rear.



Square - 9.5" 265/35/18 to a 275/35/18



Wheel Alignment for Staggered "Before" vs Square "After"

Thanks, m-cast - that’s a serious looking M Coupe!

Rotating tyres is one reason i’m considering a square setup for the street. I won’t be putting many km on the car and the front tyres may even pass their use by date before running out of tread.

Is there any reason to NOT run a square setup on the street?

I’d like to run a 255 tyre all ‘round but suspect that wouldn’t fit on the front without body work and/or serious alignment settings?

Cant comment on square setups much but Im running a 255/35/18 in the front on stock suspension and don't have an issue with rubbing. A different tire may change that completely but I'm running Michellin PSS and they've been perfect so far.

It all depends on the offset of the wheel. My square set up has a 22mm offset which requires a lot of camber to get that 265 to fit with no bodywork. The staggered set I run an 11mm on the rear and a 5mm spacer on the front to get the stance correctly with no additional alignment needs.
