Those do look like the e60 M5/M sport wheels. If they are genuine, look up the offsets and widths and post them. Many people run 19" set ups

Your pic sucks, .....maybe they're style 166 wheels, turn one over & confirm.

Here are the specs for style 166, these offset (ET) numbers are Not in your favor.

Series Model Except Size Use ET Kg
5er E60+ M5 4x4 8,5x19 front ET 12 13,27
5er E60+ 4x4 9,5x19 back ET 28 13,27
6er E63+ M6 8,5x19 front ET 12 13,26
6er E63+ 9,5x19 back ET 17 13,26

In your 3rd pic it looks like the ET is 40, is this correct ?

Next, find out if your wheel center bore is 72.6, if it's bigger you'll need hub centric rings.

As for tire choices, it's my opinion that you should run either a 225/35-19 which will be slightly stretched on your 9.5" rim, but will be lighter in weight & closer to your preferred overall diameter of 25" to keep things like your speedo happy.

Or a 235/35-19, even though this tire is slightly better suited to a 9.5" wheel width, it's a littler heavier & bigger in overall diameter so performance will suffer.

Realize that as your wheels & tires get heavier & heavier, plus when your overall diameter gets bigger past 25"; Your 323 will feel like it magically LOST 25 WHP.

The centre bore for the e60 and the e46 is 72.5 on both.. the et says 40. And the width are 9.5 front and 10.5 rear.. i might be off an inch if i measured from the wrong part of the rim. I measured lip to lip not where the bead on the tire goes. Im a mechanic and my boss can get me 225/35/19 goodyear for a good price. Now im a little more convinced of the fitment. Do you think i will need fender rolling or spacers? Im not looking for extra special fitment look i just want to put them on and not rub..

The loss of hp is gonna hurt because the car is only a 2.5.. it has an intake thats all.. if it feels weak when i put them on ill buy headers for it.. another question is there any tuner for the 323 e46?

Don't make the mistake of trying to put a 225/35-19 on the 10.5" rear wheel, you'll want the 235/35-19 which again will be slightly stretched.

To regain the "feel" of your original HP (or more) with these wheels, here's a simple list:

1) Diff
2) Headers
3) Pulleys
4) Shark Injector # N4MS42
&
5) Cams*, since your a tech this shouldn't be to much trouble. PM me when you want some.

* Stock 323 cams Suck for performance.

I thought You were the mechanic ?

**********************************

Since you already have a 3.46 ratio, you'll want a 3.64 diff. These tend to be difficult to find, so you might be better off buying the R&P separately & installing them yourself.

Here, play with this diff calculator:

Tough choice, both will work.

Look at the tire specs closely & try to figure what best suits your needs.


On a side note, Weigh one of your current wheel & tires on a digital bathroom scale to get a semi accurate weight. Then when you get your new tires mounted, weigh them too, then report back with the two weights.

Honestly they look nice but the performance loss would annoy me to much. I would look at getting different wheels. Just my opinion. Unless they are really light.
