Going to need a test fit to see if they will clear without spacers. They just should, but if the tires run wide or have abnormally large curb protection then you will need small spacers on the front.

My car has E30 M3 5-Lug, did you take that into account? I thought I was looking for something closer to 20-25mm offset with E30 M3 5-lug. If ET35 will fit with little to no spacer and 235/35 17's, that would be awesome!

Mystikal, et al.,

Current setup:

• 1987 325is w/ 4-bolt hubs
• Bilstein Sport front
• Koni SA rear
• H&R Race springs
• Racing Dynamics sways - 22mm front / 19mm rear
• E30 M3 camber bushings
• Dinan fixed camber plates - 3°
• UUC BBK (see attached fitment template)

I want to stay with 16" rims.

Is it possible to run 235s? What offset will allow the widest tire width?

Here's the thing: there are no 16" 235 tires that could fit an E30.

Need some help - i'm a complete noob when it comes to wheels and fitment:

I'll be running filled-and-drilled 16x8 et23 style 5s (from an e38) with 5mm spacers on my 318is, lowered on IE3 springs. I've got 205/50/16 Falken Ziex tires to mount, but really want to go wider to avoid the stretched look, and gain a larger contact patch. Ideally I would go 215/45/16. I don't want to roll my fenders, though! Any thoughts on whether or not this it's possible to run 215/45/16 without rolling fenders? a 40 series tire might work, but i'd like to keep the ride height as high as possible - I already scrape too much!

Thoughts? Thanks!

No need to roll the fenders with that setup.

I did. They'll fit with a 5mm spacer needed at most. 235/35 doesn't exist, and wouldn't be very fun to mount on a 7.5" if it did.

Booh! In that case, what's offset do you suggest for 225/45/16?

ok so im buying a set of corvette c4 salad shooter rims.
16x9.5" all around. et38.

i want to run adapter on these. something like 25mm up front and 30 somethng rear.
tire choice im looking for is a real tire, no rubberband, something like 245/50 or 235/40

i know ima need to roll the fenders, but how much?

16x8 +22 would be about ideal. Give or take a few mm on the offset and you're good.

You're not mounting anything more than a stretched 225/40 on those without flares.

[E30SPDFRK]

You're also not going to get them to fit with a 25mm adaptor, you'd need a 32mm absolute minimum.

Thank you!

Trying to get widest autox tires on my E36M3 front/318ti rear 5 lug swap, ground control coilovers as well.

I'm currently running the BBS Style 5 17x8 et20 with a 215/40-17, quarters mildly flared out and front lips rolled.

Question is, I am being given a set of 17x8 et47 track wheels, can I run 245/40-17 BFG R1 or should I just go for the 235/40-17?

Thanks

^ I like the height on 235/40/17's better. If you are going with a track specific tire it will also run quite wide, and a 235 would square off on a 8"

Edit (again) sorry

hey jay,
I have a late model. Thanks to you my setup fits perfectly. 15x8et20 on 225/50's. Looks super aggressive. The front fits amazing. The rear appears to be sunken from the fender lip. although because its a late model it has that bump in the inner fender. So its only clearing that by mm. My question is, can I bang that bump out a little bit without fucking up my fender on the exterior? I want to run a 10mm spacer out back.
thanks man
