18x8.5 Square Set up for 08 328xi?

HDub91 · 05-05-2013, 12:29 PM

I'm looking to get a new set of rims for my 2008 328xi.

I'm pretty sure I have the sport package. I know I have sport seats, steering wheel, paddle shifters, faster speed....but there is no mention of a sport suspension so I am not sure.

Here are the rims I'm considering getting http://www.elementwheels.com/proddet...od=BEY-1885T5B

I am also considering these http://www.elementwheels.com/proddet...od=BEY-1985T5B (19x8.5 square set up)

What size tires and offsets should I get for my set?

Will I need spacers for my back rims or a different size offset for the back rims?

Sorry for the beginner questions, this is the first time I'm doing something like this and I don't want to mess my car up!

Thanks for any help guys, speedy answers would be appreciated

because I am hoping to order the rims today or tomorrow.

Someone's got to know the answer.

Should I got an offset of 30mm or 40mm for the offset on the back and front?

Will I need any spacers?

ET40 will be really sunken in. ET30 is the way to go all round if using 235/40/18. The front will be nicely flush, and has a slight risk of rubbing at full steering lock on bumps depending on the tire brand. If your car is a sedan you could still fit 12mm spacers on the rear, but less on the coupe.

Thanks for the help John.

Is it the 8.5 width that will cause the rubbing?

Last Questions

If I do go staggered, I'm thinking of going http://www.elementwheels.com/proddet...TSW-1895treblk

(18x8 front) ET35 on 225/40/18 Toyo Proxes 4 Plus
(18x9.5 back) ET35 on 255/35/18 Toyo Proxes 4 Plus

Should I use any spacers for the rear wheels in with this setup? The rims on the rear also have an offset of 20mm available but I thought for e90s the offset is supposed to be 30-40

That setup seemed very close to the staggered setup up offered straight from BMW so I was actually leaning toward that right now. Plus I think the all black rim with the 2" lip in the back will look nice with the Alpine white paint job.

No. An 8" rim would have the same potential issue. Its because of the wheel offset and tire width. If you are fitting 235/40/18 Toyos they shouldn't have any problem because Toyos are made with round shoulders that allow extra clearance. If the tire is a extreme performance / sport focussed design with square sidewalls there's more chance for it to rub in some situations.

If your car is 2009 onwards, that's true. For 2008 earlier E90 sedan they have more 8mm space on the rear fender so can accept a lower offset wheel. ET20 9.5" with 255 may be possible in that case, but I won't recommend it to you in cause you have problems. Also be aware the Toyo's 255 might look slightly stretched on a 9.5" and leave the rim a bit exposed if get too close to a curb.

What about

18x8 235/40/18 ET35
18x9.5 265/35/18 ET35 or ET20?

???

Sorry for the extra questions, I want this to work right.

b-man · 05-06-2013, 11:31 AM

I think that should work too. I'm not 100% sure about ET20 though. I've seen people do it but I can't remember if they had 255 or 265

HDub91 · 05-06-2013, 12:05 PM

too bad the 255 would stretch, that would be -0.236%.

The 235/35/18 with 265/40/18 setup is -0.389%.

Still good though.

Thanks for all the help guys, I think i'll get the ET 35 all the way around to keep it safe.

HDub91 · 05-06-2013, 01:54 PM

Also in regard to the Toyo Proxes 4 Plus' (255/35/18) stretching with the 18x9.5 rears...

Unfortunately the Toyo Proxes 4 Plus' aren't made in 265/35/18 but they seemed like one of the better all-season tires I was able to find.

Can anyone recommend me some good All season tires?

I was considering the General A-Max AS-03's but didn't think General has as good of a reputation as Toyo.

Thanks again

They would fit fine. See the link below for tire/wheel specs. Some would recommend going ET35 on both and use 5 to 8mm spacers front and back if you want a more aggressive look.

255 would not looked stretched on 9.5-inch rims (see link below), but that is the max wheel width acceptable for that size.

I hope you meant 235/40 Front and 265/35 Rear because the sizes you quoted would not work. See the link below to make sure.

Conti DWS

Just got rear-ended at a red light

Car wouldn't start, and it looked like there was a airbag malfunction, so the rims will have to wait a week or two.

I was literally on my way home to order them TODAY.

That's no good!

On an AWD we've done this setup before, quite a few times. ET35/ET33 in your case, OP.

Yeah I am pretty upset right now. A clean title down the drain to no fault of my own. We'll see what the damage is, but on the bright side I am at 0% fault so I guess it as good as an accident could have went.

With the car already in the shop, I guess it is a good time to get those windows tinted though!

HDub91 · 05-15-2013, 03:03 PM

The wheels have been ordered! I ended up going with conti dws and got them to give me a price match, along with $200+ worth of free add ons. The wheels should be here in 10-14 days.

Also I talked to body shop today and they said my car should be ready in 10-14 days as well, so things are lined up perfectly!

I'll upload pics right after installation.
