215/40/16 all around if you want balanced handling, 205/45/16 fronts if you want the stretch to look more equal (the rears will still be more stretched) and yes it will mount (don't believe a tire shop if they say it won't).

The problem is that the wheels have been modified, and are no longer valid 5x120 wheels. The pressed-in inserts most likely cover up the old bolt pattern, so they are not BMW wheels at all anymore.

On another note, if they still were 5x120 you'd need to be running E30 M3 5-lug to get them to work, which is like $1500+ in parts.

1500+ in parts..3200 for the rims(CDN plus shipping/duty--thats what she paid)

very very expensive upgrade..


I'm having a tough time finding wheels that i like... I really like this style..and want something with some width..
also liking BBS LM style..but have only seen that in 5lug as well..

maybe I'll just go with the dark bronze Ronals I saw awhile ago..(17's)


thnx for the input guys!!

[Mystikal]

There are 4x100 BBS LMs. Look at the BBS Japan website (they are only in 17x7 ET40 last time I looked).

[kapt_krickee]

liking the BBS RS-GT's also..but no 4lugs

^the optional?

Okay.

When you order rims from Tirerack, most of them are not E30-specific wheels, meaning they have oversized hub bores as well as incorrect offsets. What Tirerack does is produce custom spacers for each wheel that allow them to work as both spacers and centering rings, making the wheel effectively perfect for the car. For example with the RG-R's, they would probably ship 15mm (maybe 10mm) spacers as well as correctly sized bolts for your application.

The Tirerack BBS pricing isn't bad at all, but shop around local to see if they can match it (most likely not with the horrible USD right now). And the Pirelli Nero M&S is a really great tire, but get 215/40/17 (Tirerack's tire recommendations are off on many different cars for some reason).

Tnks a lot Mystikal .

hi all. great thread!

i'm running 15x7 Kazera KZ-M rims on my 1988 325e. i'd like to put either 205/50/r15 or 225/50/r15 on it. i'll be using the tires mostly on the street, and once a month at autoX driving school, which i'm starting this year.

tires i'm considering:
Falken Azenis RT-615
Michelin Pilot Exalto PE2

questions:
1) what are the pros and cons of going with a wider tire (the 225)?

2) is it true that the 225 will handle better than the 205?

3) is it true that 225/50/r15 will definitely fit a 15x7 rim without rubbing (no fender rolling required)?


thanks!

First off, neither of the mentioned tires come in 225/50/15, so I guess that solves that problem.

Pros of a 225:
Shorter stopping distance
Increased lateral grip
Aggressive look

Cons of a 225:
Decreased steering response
Decreased hydroplaning resistance
Increased tramliming

The 225 will technically handle worse, depending on your meaning of handling. The 225 tire is on the outer edge of recommended width for a 7" wheel, so the steering response can get sloppy, along with transitional stability. That said, with a stiff enough tire (BFG G-Force Sport, Yoko ES100, Hankook R-S2, etc) these downsides are minimized.

225/50/15 can fit without rolling (I personally did that), but it depends on the following variables:
- Car year
- Suspension
- Tire model
- Wheel offset

Provide me with all of those details and I can tell you if it will require rolling. Honestly don't shy away from the job, it's very simple.
