wheels: oem 14" bottlecaps
tires: p205/75/r14

1) aside from cosmetic issues, are there any problems running this setup on a 325ix w/ stock suspension?
2) would these come close to fitting a RWD e30 which rides on H&R sport springs + Bilstein sports?

I know I won't be as quick as on my 195/65/r14's, but I look at it the same as I would swapping in a taller differential.

Tires are way, way too tall.

This question is for the e36 and not e30 but BF.c is not that much help.

I have a e36 m3 with BBS rx 17x8 wheels ET 38

I want to run 245/40-17 in the front but don't know if I will need spacers or not.

any help would be much appreciated.

Coilovers? If so, which ones?

If not, then no spacers needed. It just barely clears.

Funny thing is, my E36 fitment knowledge is easily 75% as in-depth as my E30 brain matter, which is realistically very powerful. But frankly, just keeping up here is a full time job. Plus, E30 guys are where my heart is, screw the E36 crowd. :p

HI,

I am running 15x8 wheels with 215/50R15 BF tires, I am thinking in running a 225/45R15 Toyo R1R, this tire is not available in 225/50R15,

will the 225/45R15 be a good choise being around 23" tall or is it too small?

Thanks, Mario

Not too small at all, I'd go as far to say that more E30s are running ~23" tires (usually 205/50/15 or 205/40/17) than the proper stock diameter. Aside from the aesthetic change and almost imperceptible gearing shortening, there is no difference.

I don't have coilovers but I do have bilstein sports with H&R race springs. so it is a low set-up. If you think I might need spacers, do you have any recomendations on some good but not too overlypriced wheel studs?


I love the e30 guys too, its hard not too. I wish I still had mine at times.


Thanks for all your help!

205/75/r14's on a stock-suspension 325ix .... ?

Tires are way, way too tall.

Too tall to fit?
inner wall will rub? or tread surface?
If so, what is the tallest tire (195 or 205 in width) that *will* fit the IX ?

i just picked up a set of 17x8.5 et25 wheels for the rear. tires are 245/35. i dont plan to install them untill i get some springs. can i run ie3s/h&r race?

[aworthybrother]

I believe it was your PM i just responded to? In any case, either spacer will work 100% fine.

Hi Jay,

Thanks for replying to my previous question.

I just purchased the 15mm spacer with longer bolt from ECS Tuning (http://www.ecstuning.com/BMW-E30-318...cers/ES260065/) It looks like the length of the lug bolt is longer than it is supposed to. It is hitting the hub for both front and rear when tightened properly.

I measured the longer lug bolts and it is 40mm.
My question is:
- is 40mm the correct length?
- is it safe to have it replaced with 35mm?

This is how I measured the lug length:


Thank you.

Thank you very much for your information and help,

Hey Jay, Finally got my car sorted mate. 16X9 all round with et11.5 in the front and et8 in the back tires are 225/45/16s with no rubbing. Thanks heaps for all your help mate

hey, im looking into a set of wheels for my 89 is and heres what i found

for the rear
18x8.5 4x100 35

for the fronts
17x7 4x100 40

makes sense or is this too wild?
the only reason the rears are bigger is... shit ionno i figured it would look sick

You won't need spacers then. Coilovers actually reduce space, hence why I asked. Your setup will be 100% fine with just a basic rear roll.

Tread surface, on the front wheelwell (fore and aft).

E30s don't like tires much taller than the stock 24", as they were in reality only designed to hold ~23.2" tires in the first place (early E30s ran 195/60/14).

I don't make a habit of recommending anything larger than the stock diameter.

Responded to your PM. Flat fender roll should be okay.

I'd send them right back to ECS. Sounds like they shipped the wrong ones.

Looks amazing man. This has been what, a 1 year debacle? lol, glad to see it all fleshed out.
