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

[Mystikal]

Need some advice on what tires, here is the current setup

Wheels: 16x7.5 ET30 Borbet Type C

Car: 1987 325i Sedan

Modifications: Front Fenders Rolled, Rear Quarters still stock, Bilstein Sports, H&R Super Sport Springs

Current Tires: 205/55R16 Front, 225/50R16 Rear (long story on the stagger)

Looking at doing 205/50R16 Front and 225/50R16 rear, wondering what spacers i would need and if i would have to do rear quarter work (would love to do 225/50 all around)

I had those same wheels and they rubbed the front struts without spacers. Are you saying you're clearing them with massive 205/55s too? That's weird.

I recommend 3mm front spacers and 225/45 tires all around. You're getting away with massively oversized tires at the moment it seems but I can't recommend it.

Ok I ditched all my other plans and I need the following info.

1990 325is, it will be on Koni Adjustables with H&R Sport springs. I have IE Wilwood BBK the 16" slim versions.

I want to run 16x8 all around with 225/45R16, although if its better I could make the barrels 7.5

I am currently having custom BBS RS's made so I can do any offset I need. I was thinking ET22 would clear the rears so I would not have to roll.

If that wont work is there an ET in the rear that will work so I dont have to roll?

+22 all around is great for 225/45s

[Mystikal]

with 17x8.25 et25 wheels would 215/45's work? Would I need to roll my fenders just to get them to fit? If so, what would be a more preferable size (if there is one)?

Thanks

Without rolling, 215/40 is perfect. With a rear roll (mild), 235/40 all around is possible.

Came across a deal I couldn't pass up. Style 42's 17X8.5 and 7.5 staggered set. Currently has 245x45 and 225X45's mounted on them I think they are ET41 but they are not marked. I have a 1989 325I with H&R Sport springs and Bilstein Sports. I have the 42 Draft design 18mm 4 to 5 lug adapters. I am open to a mild fender roll if needed. Also open to e36 M3 struts. Any chance these will fit or what tire will fit or just dismount tires and run on my BBS RS's on my E24?

Awesome and rare. They should be +41 square off a Z3. 18mm adapters are perfect. I'd run 205/45 front 215/45 rear, personally.

Enkei 92 15x8 et 25

Planning on mounting these on to the car in the next few weeks. Car is currently stock height but will be installing m3 springs with hds, purchased the spacers, now just need the proper tire. I know many people run 205/50 but would 225/45 fit and not rub?

You should state what size spacers you purchased. If it's the recommend 3-5mm front only, then 225/45 will fit all around no problem.

Hello, on my 1989 e30 sedan was wondering if these offsets will be aggressive but not too pokey.
Edit:
Front 16x9 215/45 et5
Rear 16x9 on 215/45 I've read et5 is flush.

I'm running fifteen52 formula TRs.


I know slight camber might be needed I have plates.

Here is image I'm going for. Except he is 16x9.5 rear





So eventually I will go bagged(not looking for static vs air debate!)
But don't want the wheels to look to "donk" with my current height. Which is pretty low for springs



Let me know thanks!

205/45s would suit this fitment a lot better. It will still rub, and require a ton of fender massaging. But it's doable.

All -

Currently looking at running a 16x8 5x120 Et14 on a '92 E30Ic. Tire choice not yet defined, so feel free to add recommendations there as well. I will need to run adapters

I'm looking for the wheels to be flush as possible, but not pokey - how would these fit, look, etc.?

Car has bilstein shocks with eibach springs.

Thank you for an insight and feedback provided

If you need to run adapters, the offset is already too low to work.

[Mystikal]

Sorry if this particular setup was asked before but i searched abs couldn't find it. Looking to get a set of 17x8 +30 and don't want to roll fenders. Does anyone know if this will fit with 205/40 17s?

Thanks and again, sorry if i overlooked this question.

5mm front spacers and you can fit a lot more tire than that. I recommend 215/40 or 235/40 all around. No rolling needed.

Billi sports with IE3 springs ..

Can I run 225/45 on 15x7 et25 fronts w/o spacers and roll ?

I'm combining with 225/45 on 15x8 et25 rear ..

or am I better running with 205/50 on the fronts ??

TIA

Ooh, nice. Run the 225/45s square. Tons of turn-in grip, no mods needed.

[Mystikal]

Well Mystical i didn't expect that you would be active after so many years! I mean you are beyond a forum moderator, you are a something like a doctor for the E30 enthusiasts that cannot find peace with their cars! I really admire you, i wish you the best my friend..!!!

Well after many modifications i finally accepted the fact that 7x15 ET12 is not the correct wheel for the late facelift E30 i have. There is no way to use the car 100%. The look is fine but when two people stay in the back, or worse when you put things in the trunk and you have people in the back the rubbing is always here, no matter the height of the car. What pisses me off is that 205/55/15 tyres are more expensive than the 7X15 et12 wheels, so it is pointless to buy expesive tyres just to tear them apart after 100miles...

The question is, sould i buy second hand original 15'' bbs 15X7 et24 or a new set of Ronal LS 15x7,5 et25 ? Is the fitment exactly the same? Do you have any opinion of the quality of Ronal LS or they are cheap made wheels?

You see the whole point of aftermarket wheels is they have the beatiful lip aroud the wheel that the originals do not have....

BR Mystical!!!

No problem! Yeah I'm still here, sometimes not certain why, but hey I'm here!

15x7 +12 works well with a 205/50.

Ronal LS are fantastic quality wheels. I'd buy those. You can even fit 225/50/15s on them.

[Mystikal]

So 205/55r15s on 15x7.5 et0 wheels rubbed ever so slightly in the rear with a half assed roll (lips are bent to a 45° angle with a baseball bat). Still managed to get to the belts before cutting deeper than the letters.

Now I wanna play offroad. if I finish rolling my fenders flat a 205/70r15 on the same rim should be good, right? What about 225/70?

Looking at the new General Grabber AT3 that's coming out this spring.

So it's already rubbing pretty severely, and you want to run a tire that's like 2" taller? No, they won't even be close to working. Don't do this, buy wheels that fit.

[Mystikal]

spacer (size? bolt on or extended lug type?) and tire (size?) advice needed...

1987 325e sedan

bagged

16x7.5 et38 wheels

Like the flush look. "FuN" car for cruising and hard parking...have another car for corners and speed.

Your guidance is gold.

Thanks in advance!

You'll spend $300-400 on hardware to fit those flush. 25mm front, at least 30mm rear bolt-on spacers. IMO it's just not worth it.

[Mystikal]

So what would be the perfect offset on a 16x8 wheel front and rear to fit 225/45R16 tires

I can roll the rear but is there an offset that would fit my car perfectly. 1990 325is.

When I say perfectly I am not a fan of the poke I would like it flush, I will be running H&R sports.

+23 is ideal.

Greetings,

Can anyone tell me if these wheels will fit my 1992 E30 318i convertible with stock suspension?

Here is the link with the wheel specifications listed below.

http://www.ebay.com/itm/16-RS-STYLE-WHEELS-RIMS-SILVER-FITS-E30-BMW-3-SERIES-TOYOTA-YARIS-TERCEL-/252707364082?_trksid=p2385738.m2548.l4275

Style: RS Style

Size: F&R: 16X7.5

Bolt pattern: 4X100/114.3

Offset: F&R: 35MM

Hub Bore: 73.1mm

THANKS VERY MUCH

With $200 worth of spacers and rings, yes. But just find similar in an offset between +15 and +25. They will bolt up then. There's like 500 factories in China pumping out those fakes you can find any size or offset, just search more.

[Mystikal]

Jay,

Thank you for the response! Do you think it would be possible to run a 235/40 in the rear instead for more width/less stretch? I'm been looking at examples of e39 style 32s and I've seen the same specs tires suggested, but two have been running adapters (18mm and 20mm)and one running z3 rear hubs(+23)

With the z4 hub it only pushes out 2.5mm. So my thought is I have between 15.5- 20.5mm more space between the hub and fender than the above mentioned setups.

Also, could I run more tire in the front with the fenders rolled?

Not a huge fan of stretched tires, but will deal because I like the wheels.

Thanks!

It'll rub with any more tire. The offsets are too low.
