ASK ALL WHEEL/TIRE FITMENT QUESTIONS HERE - The Official Wheel/Tire Fitment Thread

I've been looking for 16x8 rota slipstreams but seems like to get them the way I want I have to wait 2 months so I can't do that. I found a different set of wheels but they are 17x8 (et25) & 17x9 (et20). I have a 87 325is on bilstein sports & h&r race. Now I think they would fit but i'm unsure about tire sizes. I was thinking 215/40 up front w/ 245/35 in the rear so they would be the same diameter. or is there a size in between that I could fit on both rims? Any suggestions?

Those are pretty much ideal rim specs. Interesting.

Your tire idea is excellent, and with your '87 rear arches you have a decent chance of getting the 245s back there. Still, expect to be doing some fender rolling back there.

You could also go for 235/40/17 all around. But this would actually require more work on the rear fenders, due to the taller sidewall.

Mystikal...
I'm sorry if these questions have been asked before and I know this is an e30 Forum...
I just bought a '96 328is...
I've had an '84 325e for years and I still have it, but I am new to the e36 world..
I wanna buy some wheels and suspension for the e36...
I am probably going with GC coilovers for the drop...
For the wheels, I am probably going with 18's or even 19's...
If I want a flush fitment with no staggered wheel widths (unless I should run staggered widths on an e36), what offset am I looking for?
What wheel width do I want, Front and Back?
What is the max tire width I can go with the max wheel width you recommend?
And what is the stock Hub bore on an the e36?
I like the set-up you got going in your sig.
Finally, do you know of a good e36 factual website like Strictly eta is to the e30?
Thanks for your help. You should be paid for this. I only hope you can answer my questions before you decide to throw in the towel.

E36s are happiest with non-staggered tires.
Offset depends on rim width, and also what you consider "flush".
The widest tire you can get on all around is about a 255. This works well on a 9" rim.
72.56mm hubs.
Strictlyeta is badass, and the E36 world can't handle such levels of awesome.

I may instead be getting a 5 lug e30, e36 m3 in front m roadster in back. the tires I have are 225/45/17 up front and 245/40/17 in back. Will the tires fit for an e30 or should I get something smaller

I've seen those on an early E30, but it still rubbed I'm pretty sure.

Smaller is a better idea. 215/40/17 all around.

[Mystikal]

17x8et0 It should poke a little im sure. And yes im willing to stretch.

Tire size and Fender work necessary?

205/40/17, and heavy fender rolling. Heavy.

[Mystikal]

Jay, Thanks for this INFORMATIONAL thread! my question:
I have 15x7 BBS RS +25, for front and rear, and i am running 205/50/15s.
Can i run 20mm spacers all the way around?

Not without a lot of fender work. Even a 10mm will require fender rolling.

[Mystikal]

I think I need to sell my Borbet A wheels due to BBK upgrade. Im looking at the Keskins KT9 or KT 4 New racers

8.5x17 ET 30
or
7.5x17 ET 35

KT4 New Racers
8x17 ET 35


any of these wheels work w/o modification and what tire recommendations

appreciate the help!

All of the above need spacers. Are you looking for wide tires?

[ja burna]

I'm looking for as wide as I can go without major surgery..

as for spacers,

front 5mm, and back 10mm? will this work?

[etxxz]

what about

225/45-17 front on 17x7.5" et41 (DSII) rims on my daily/drifting. I tend to rub in the inside back/frame at full lock. spacers? caster? I can adjust camber and caster to some extent on kmac plates.

For my track rims.

245/40-17's front and rear on 17 x 7.5's et41 (DSI rims)
the front may rub on the frame/inside at full lock. I won't turn in that much unless i spin out.

currently running 235/40-17 RA-1 tires. finding affordable r-compounds on 245/35-17 may be difficult if they even exist.

yeah I didn't think the tires I had would fit, they were e36 fitment.

the guy I'm getting the car from has dsI's on it now, 17x7.5 all around, and he's running 235/40/17 all around. (may have rolled the fender lips I don't know). are dsI's the same offset as m contours?

So I could do the 235/40/17 up front, but what should I do in back considering it's an 8.5" wide wheel? Same thing and stretch it? or will it rub?

Sorry, I should clarify...
To me flush fitment is just inside the fenders... enough to be able to turn while slammed with stock camber... no stretch or poke....
I am trying to buy some wheels and I want just the right offset without spacers...
If I want to run the same wheel width at all 4 corners, would the offsets be the same?
Which wheel would give me the 'flush' fitment I want, a 18x8 et35 or et40?
How about a 19x8 et35 or a 19x8.5 et 38?
Ok, and finally, do you know what stock wheel width and offset are for my '97 328is? Where could I find that kinda info?
Thats it... no more q's... Thanks Jay.

Wheel and tire help ! ?

I have a 1986 325 with Bilstein Sports and h&r springs. Is a staggered set up on an E30 stupid? Looking at possibly purchasing some used wheels, 4x100 - 16X7.5 (f), and 16X9 (r). What kind of tire set up is best or will work? or is 9 just too much?
Any advise or help is appreciated . .

[johnwoo]

ok here is my setup, decided to go another route this time

keskin 16x9 +15 lowered on fk 60/40 springs. i know i need a 3mm spacers up front. i was wanting to go 5mm and 8mm spacers for front and rear. 205/45 tires. my question is can i go 8mm spacer in the rear? or should i just do 5mm all around. i am rolled in the rear also. thanks for the help

anyone? plzz i have a person on bimmerforums waiting to sell me 245 hoosiers..

[Stephen]

Alright. hoefully thisll be the last question form me for a while. 16x8.5 et11.

should fit pretty flush maybe some poke.. 205/45 or a taller sidewall? Yes im perfectly ok with stretch, and i presume fender work will be needed
