Man!
Good thing you have an iX or I would really have to bring out the poser card for running those flares. Some how owning an iX gives you a hall pass.
:)

J.

You know how it is... you stare at your iX long enough, then at your is, and it looks like something is missing. :-D

I put on the flares to cover as much rubber as I could cram in there, and flares do the job. Now the rear looks like it could fit a 245 R888... but Toyo doesn't make that size in the 15", and any other wheel size starts to get too tall (even the 235/50-15 is a little tall). I really like the R888 as an ultimate street tire, been running them (and the previous RA-1) on my M3 for a few years already.

I really like how these chubby tires look. Don't care for the big wheel/narrow stretched-out tire look, it's so anti-performance and overt. This car is old-school stealth, with all the goodies hidden. I build my cars for me to drive, not for someone else to look at.

Rob, look at my pics in the members rides and I got the 235/50-15's to fit up front. I need to hit the front fender wells with a hammer though as they rub near full lock, otherwise no issues.

I went through your thread and didn't see anything about this... with that much lowering, are you having any rubbing with the rear tires?

- Rob

[cheades]

The rears have the inner lip rolled and just the right side needs to be rolled in more to take care of a little rubbing when I hit a bump. Now that I have driven it a bit I can see exactly where on the front the tires are rubbing to fix it, will try to take pics when I do that.

Agreed on the chubby tire look, give me grip please.

Update: no way is the 235/50-15 R888 fitting on the front without hitting the strut. Even the smallest spacer puts it outside the iX flares. Switching to a 195/55-15 front.

Rears, however...



Muhahahaaa...

More pics to come when the new fronts arrive.

I think I had an inexcusable brainfart that day.

9.4" will not work on an ET25 15" wheel. I've known that for years. This is why Ronal LS guys could never run S-03s without spacers (they are 9.3" wide on a 7.5" wheel). That is one of the first E30 wheel fitment things I learned, and that was literally 6 years ago.

I'm sorry for that, I have no idea how I typed it. Damn.

As a side note, as the info cheades is currently sharing suggests, you can likely get away with a 3mm spacer, if they cleared your brakes. Which is actually what I'd recommend, as with most 8mm spacers (which don't have a hubcentric lip) the wheel is sitting on little to no part of the hub.

There is also more room in the front fender of an E30 than the rear, given the same offset wheels F/R. Getting the 235 up front shouldn't be an issue (I have my 225/50/15 R-S2s on an ET20 wheel up front...9.2" section width...never even rolled them and have yet to touch a thing in thousands of kilometers).

But yeah, again, sorry. No idea what the hell I was smoking that day.

i bought some 17x8 i dont know the offset on the wheels but the wheel alone sits about 3/8 inch from the strut im gonna be running 205/40r17 what size spacers im i goin go need, and longer bolt/ studs?

If it's already ~9-10mm from the strut, you won't need any spacers. I'm assuming you test fitted this on the front, and that's where any contact would occur.

[Rob@UUC]

that's what snow tires are for. :p

I'm not sure I would drive with those tires on the street anyway, although I'm sure it would be fun!

Need minimum 16" for the BBK on the iX.

D40 M2s are simply high performance street tires.

The R888 is technically a DOT-legal R-compound track tire, but in all reality, it's a mild R-comp. We use them as rain tires on our racecars. I've gone through two sets of RA-1s and one set of R888s on my M3, and I typically get 10K-12K miles, including about 6-12 track days a year. For R-comps, they wear like iron.

Then something still doesn't make sense... see the pic of my front tire sticking out more than the 15mm spacers alone are responsible, and with the iX flares.

I don't think 3mm will let the wheel clear the brakes... this wheel has just enough of a detail by the spokes that it wants to hit the high part of the pad backing plate sticking out of the caliper. I might have to find a plug-in hub extender like TMS makes for the 5-bolt setups.

I'd say it's because of the big brakes, but if they were actually adding to the track width then you wouldn't have strut clearance issues.

It's hard to tell you exactly whats going on from the pic you posted. I know my front 225's look like they might not slip under the fenders, but they easily do. And cheades isn't the only person that has run the 235 R888 up front on here, I've seen others.

Hey Jay,

Would a 17x8.5, 25mm et fit on H&R race, billy sport?
its a late model (89).
What tire size would you recommend?
Would i need rolling?


Heres the wheel.


Thanks jay,
Andrew

Ah, Rota D2. Have you actually seen that wheel from a more extreme angle? The spokes actually come out PAST the lips. The Rota stock photo pics really deceive.

Anyways, they would need very small spacers to clear the front struts. 5mm would for sure do it.

215/40/17 is a good choice. If you don't use any spacers in the rear, you can get those on all around without any fender rolling.

I know absolutely nothing about wheels, so I came here.. I have an 87 325es, and wonder if these will fit, or what I'll need for them to fit. If they do, I'll need tire size recommendations.
Thanks

Damn!
That was one of my worries.
I know i wouldn't like that.
Thanks Jay,
Your always quick to answer!

They require 20mm spacers to fit properly. Which raises the purchase price ~200-220.

Take a look here, style 003 is very similar and doesn't require spacers: http://eurostopusa.com/Wheels/bmw_3s_wheels.html

I'll confirm that's 100% not true.

But you're welcome! :D

Thanks a lot! Any similar sites to the one you gave me? I'm open to just about any style wheel and am having a hard time finding 4x100
