View Full Version : +15 offset and 235/45 R17 on an E36 ?

I am looking at these Ronal rims that are staggered 35 in front, and +15 in the back.

Anyone know if it will clear an E36 in the back? do I need spacers for the breaks? rubbing? is it sufficient to test mount them and lower the car since they are in the back they should not move..

Any input is appreciated.

Tires are oversized for an e36.

Need width and offset of the rims to confirm fitment.

Won't work regardless of wheel width.

Won't work regardless of wheel width.

For sure with current tires, could/might be able to make it work if he ran some stretch, which would require a new set of tires.

wheels are 17x8
+35 front
+15 back

tires are 235/45 R17

Either look for another set of rims .... and if you want these rims then it could work with a few adjustments... the rear is just too aggressive with the offset, it will rub

*Oh and wrong section to post this in brahh

Will rub like crazy with those tires. You won't even be able to drive it with the rears the way they are.

ok thanks for the replies everyone... from my understanding the biggest tire I can run is 245/40 with OEM offset is that true ( on a 17 inch rim)?

You won't be able to run 245/40s in the rear with those offsets.

The only way to pull them off, is if your car is slammed and you run smaller stretched tires with the rear fenders pulled.

I am keeping everything like it is , not going to roll the fenders. getting a new suspension with lowering springs . so realistically, whats the widest tires I can run in the front and in the rear?

What is your current suspension setup? Stock?

yep stock, but getting bilstein HDs with lowering springs.

If you don't want to roll your fender, forget even trying. My points below.

With those offsets the front and rear aren't going to be even. You can run 215/40/17 et 15 in front and 235/40/17 et35 in the rear, but it will look uneven and isn't recommended as it will mess up your ABS because the front and rear sizes are too different.

To run an even setup, you'll need 20mm spacers for the et35 wheels and 215/40/17 tires for et15 all around. This is an aggressive setup that isn't for everyone, so it depends on the look you are going for.

I don't think you should try it unless you have coilovers.
It would look silly, unless the car is low enough, with just lowering springs I doubt you'll get it right.

This is what 17x8.5 et13 looks like with 215/40/17 tires, but it requires rolling your rear fenders.

ok this looks really good.... what I am saying is I am going to ditch these rims and tires.

And go for another setup at et +38 . what I am asking is how big can I go in front and back with +38 offset ( I think thats the offset for e36) without any fender rolling and with shocks and struts vs coilovers. with 17inch rims

^I would say 235 in the front and 255 in the back ...Thats the widest you could go without any adjustment...

But since you're gonna lower it, I would recommened not much of a wide tire at the front...

knightowl

Ok so 225/45 in front and 235/45 or 245/45 in the back would look ok ?

Will it look obviously weird running 225/45 in front with 235/40 or 245/40 in the back due to aspect ratio difference ?

Mystikal

What is the width of the wheel? E36s can fit up to 245s all around at +38 without fender rolling. But you'll want at least an 8" wide wheel to do that.

Also in the back, dont go for 45 series as it might be too tall.. Go for a 40 series as in 235/40/17

knightowl
03-29-2012, 04:27 PM
Yeah I am not looking at any wheel thats smaller than 8 inch. but I do want to lower the car maybe 1.5" front, and 2 in back

Noted about the 40 aspect ratio! thanks.

not to hijack, but to avoid clutter, any ideas if 225/50/16's on 20 ET will fit (I can roll if necessary). I assume they will, but I bought extreme contact dw's in 225/55/16 thinking I could make em squeeze and it doesnt look like it'd work even with rolling so I'm selling, but if nobody buys the rims too, I want to make sure I can fit Something under there so I don't make the same mistake and have Another set of brand new tires I can't use.

Suspension is currently H&R sports on Bilsteins but if the opportunity came up, I'd like Race springs one day, so I'd guess that would have me running into the same trouble?

thanks

What width are the wheels?

BrianM

they'd be on 16X8's (et 20) I thought that was done fairly often on e36's but my last mishap has me wanting to make extra sure

by the way, I'll post this question in my thread shortly aswell, but there's a for sale thread selling pilots (225/50/16) for a good price. There is bad toe wear on the fronts, but if I were to mount them so that the wear is on the inside on the back wheels, think I'd loose that much grip if tracking? I suppose the effective contact patch would shrink, just trying to figure out by how much in real world, since they are such a good price

thanks alot for your time

Far from it actually, 16x8 +20 (Style 5s) are usually paired with stretched 205s for clearance. 225/50 would require at least 2.5 front camber and pulled rear arches.

Most used 16" Pilots wouldn't make for good track tires as the majority of models made in that size aren't very performance-oriented. Which model are they?

BrianM
04-10-2012, 03:42 PM
crap, seriously eh? I figured a little extra track would be some free stablity, no idea it would be such an issue. I figured I'd have to roll fenders if I do get race springs but I didn't think it'd be any more trouble...crap may have to rethink plan..


the tires are pilot sport a/s plus, so they're atleast a pretty good tire (in good condition anyways)

yeesh, thanks again though

What's your budget? Tire rack sells an inexpensive 17x8.5 et42 or 40 wheel for $139 a pop. Pair that with 255/40/17 Hankook RS-3, and 12-15 mm spacers for the front and for $1200 + shipping you have a great setup that isn't god knows how old michelin all season granite.

BrianM

haha, the tire rack ratings were pretty decent for the tire, but true say about age

your rim/tire suggestion makes good sense, and the sizing sounds like a dream (from my computer-readin' armchair) but will have to wait for now. I really have no money but since those tires were listed at 250 on rims I was thinking about just going for it, since I have to do it sometime in the near future, whether I 'should' spend it or not, and then just hope I can sell the other rims soonish for not much loss, but if the tires/lack of contact patch will plain suck, I'd rather just hold out for a little bit until the right thing comes along

Are you talking about the ones you saw in the classifieds department here with pictures on an e36? Those are e36 wheels, and will fit without issue. Also keep in mind that the type of person that buys a michelin A/S and reviews it likely eats granola and ships kids to soccer practice in an econobox. Being short on budget definitely sucks, but tires are the last place you want to cheap out on. What's wrong with the wheels you have?

BrianM
04-11-2012, 10:44 AM
although the performance ratings seemed decent, granola and econobox sound terrible haha so I should probably take it with a grain of salt

and yes those are the ones I was thinking of, except I already have a set of e34/39 wheels that I bought in the fall with 225/55/16's that I thought would work...turns out it wont, so I'm trying to sell stuff and take it from there

the wheels mounted right now are old, spent motomasters on steel 15's with 1 losing air fairly quickly and 1 with a slow leak haha. I mean they work, but I can't help but feel I might be missing out a bit.

Hi, I have in target a set of 17x 8.5 ET15. for my 328 i 1997 coupe

Can you tell me what sizes of tire can it fit Stock suspension and if the can fit in a Eibach ProKit.


Thank*th-up*

^ 215/40/17 or 205/45/17. Rolled rear fenders once it's lowered.
