Will these wheels fit an e85 z4?
If yes then what would be the best tire combo?

Yes they will fit & sit very well , assume stock springs E85 then any combination below
215 40 / 225 40 18 front
245 40 18 / 255 35 18 rear

Thanks mr wilks. I’ve been wanting to upgrade but will the ride really be stiffer coming from 16in wheels? I know the z4 looks dorky with the 16in oem wheels but the ride is great with it.
Will a 17in wheel be a better compromise between ride and looks?

These 17in style 185 looks swell in the z4 too.
If i would go with the 17in wheels...which tire would be better? 225/35 or 225/45?

18's should be fine ride wise, on normal tyres.

I can’t imagine how hard the ride would be if you have run flat tires on 18s...

Not quite as hard as RFT's on 19s...

That's why I went back to non-RFT's on 18s on my new zed, looks aint everything

I found an 18inch squared set of wheels with 245/40 tires on all wheels. Will that fit the fronts or they are to wide?

a lot of "iffs" in there, iff the ofset is -50 at the front maybe
if the suspension is standard then maybe
if you have new springs and shocks maybe

otherwise you will be grinding down the wheel arch like i did
the rear will be fine

"Not exactly cossetting" is how I'd describe ride quality on staggered 18s with Bridgestone run-flats!

Thanks Mr Tidy....will use that link.

I’ve always liked the style 119 wheels,simple design and is easy to clean...but I never see one on a z4. What are your opinions on these? Will they look good on a black z4?

The 119 wheels were so cheap and it has newer tires so I took the plunge. I think it looks okey on the z4. Ride hasn’t changed much too. At least now I won’t spend so much time cleaning the wheels.

They look good - I'm a big fan of 5 spoke BMW wheels.

And as you say they are so much easier to clean! (Unlike the MV2s my 1st Coupe had).

Glad somebody liked it... simple and so easy to clean
I really prefer the style 197, it would look good on any BMW...but my back would hurt cleaning that.
