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

[CB-M3]

Read through a bunch of posts about the E38 Style 5 wheels ET23.

Current Car - 1991 318is Stock Suspension (no plans to lower yet)
e30Rob 4x100 to 5x120 adapter is 20mm.

From what I've read it is very aggressive setup which requires a small tire 205/40/16 or fenders to be rolled and pulled.

If I have the wheels filled and re-drilled instead of using adapters will the fitment be ok? What spacers will I need for rear and front? What tire sizes can I run? Not a stretched tire fan.

You'll have to go with 17s for tire selection. Something close to 17x8.5 +40 all around will take a 235/40. May need a 3mm front spacer depending on what front suspension you're using.

Thanks Mystikal!

Could I get away with 16x8 et20 on my
1988 IX with GC coilovers & camber plates?
I can do some fender rolling but don't want to get crazy.
Thank you,

Would 205/65R15 fit then? It's only .7" "wider" on each side than stock, and there looks to be plenty of clearance (those are 185/70/14s):

Might clear. Anything taller than around 24.3" and I flat out say no - some people have tried with success, some people are okay with the tire rubbing the fender well occasionally...but officially, I say don't do it. ;)

Thanks for the help! 205's sound fine as this car won't be tracked, yet. What size spacers would you suppose?

Thanks!

5-10mm front and 15mm rear. 205/50s.

Sorry if this has been covered, which it may have been already.

I am looking at TR C1's 15x7 with Et25 and Hankook R-S3's 225/45/15. I want to wider foot print because I like to do lapping days at the track. Will they clear the struts and not force me to roll the fenders/run spacers? The car is on H&R race springs with Bilstien struts.

Yup, bolt them up and go.

having trouble trying to decide between running 17x7.5 and 17 x 8.5 weaves, front and rear, or just run 17 x 8.5' s all round for ultimate dish. The 8.5's come in a 20mm or 25mm offset, intend to run a 235/40R17 on the rear when im due for tyres next and im leaning towards running a 25mm offset on the rear to make sure the tyre will fit under the guard.

Anyone run a 8.5" front and rear? just trying to work out which offsets because 60mm of dish is pretty nice :D

17x8.5 +25 does not clear the front struts
17x8.5 +20 will not allow a 235/40 in the rear without heavy fender work

So you're either stuck with a setup that will poke too much on the front compared to the rear (+20F/+25R) or the staggered 7.5" up front.

[Mystikal]

Ok so would these work and whats max tire size and series?
Front 15x8 et0
Rear 15x9 et0
I am lowered on h&r race springs, and im worried about rubbing.

Nope. You'll see plenty "have done it", but they all rub.

[Mystikal]

so 16x9 +20 all around my IX running 205/45 on tires on all tires will be okie? is running a 205/45 on a 16x9 rim be considered as STRETCHING?

im thinking about goin with the ESM 009R wheels

what center bore size will i need for my 89 325ix?

57.1
67.1
73.1

Yes, stretched. 57.1mm.

With a redrill you can run 215/45 or 225/45 on those wheels easily.

Thank you,

Yup, stick to 205/45 for tires.

I have a set of wheels that i did the measurement on but can someone do the math please on the off set number.The wheel is a OZ fittipaldi 16x8 5x120 and from the center of the backside of the hub up to the top rim lip is 5 inches. Thanks in advance.As there are no stampings on the wheel for the offset.

16x8
+20
Fenders rolled
Widest tire? Performance minded.

heavy fender work is fine.
