225s on 15s and fitment. . . ATTN: Jay

[permit]

Ben e-mailed me today. They have 15x8 ET27 as well.

Weird, I just got off the phone with Jim and said they only have ET12. Nice to know they have the ET27s though. What would that require, maybe a 5mm spacer?

[rwh11385]

~6mm from IE would work well. If my math was right this time, it would be ET21 and have a clearance for me and my beloved tire .25mm greater than a ES100 on a Ronal.

Nooooow, it would be 2.75mm closer (or into) the fender though. (I think).

all this is assuming shit, and not exactly sure on how to do these calculations, and me bored in my cubicle with crazy people yapping in the background

[rwh11385]

What's wrong with your Kosei's Heeter? Dont like 225 on 7"?

would they fit even? I'm almost at fender with my 205s. There is Kyle's friend with 225s on a ET15 15x7, but with some rolling.


I'd prefer as much width as I could get. In the future...

RS2s in 225/45 or 225/50
RA1s in 225/50

neither.


they even make a 15x8 ET27?

Remember this Robert, you gain more clearance against the strut with the tire, since it is farther from the hub and slants inwards. Doesn't affect anything for fender, unless you have a lot of camber dialed in.

Ideally 17" wheels with 255/40's would be awesome, but would require either massaged fenders or 4x4 height.

Alrite, so say I wanted the 16x7.5 Koseis with 225/45s, would I want the 12 or 22mm offset? I read the link Robert just posted, but it was never cleared up which offset was best. I'd like to limit the amount of rolling I'd have to do, assuming I'd have to do some.

Ok, another TR update. They have two +12mm offset 16x7.5s left, and a set of +43mm or something like that.

[rwh11385]

ET22 would be key for 16x7.5, as Axxe posted Ronals in ET22 would be the ideal rim.


thanks. And I would be a fair amount of camber, so maybe that will help. And a stiff rear springs, so maybe I can live with lower rear arches if I'm lucky.

Whuddup.

You guys covered a lot of ground here, I just have one key concept to get across.

See how it really doesn't seem to make sense that a specific tire on a 15x7 ET27 wheel will rub while the exact same tire will work on a 15x8 ET22? That the 15x8 wheel is A LOT closer to the strut yet there is no rubbing?

It's because the width of the tire does not change significantly between these two scenarios. When you're considering two different wheels that are well within the range of that tire, it's really only the offset you should care about. If a 15x8 wheel will fit bare, then any 225 tire will. The tire is not wide enough to protrude past the wheel.

Anyways, in a pinch 3mm spacers are cheap. My shop had them in stock (the only size they carry) and charged me $20 for a pair when my 17x7.5 ET27 RS' touched the caliper.

I have 225's on mine with no problems. How much negative camber do you have? I am running -2.5 degrees and have about 1/4" clearance with my flattened inner lips. granted my 225's are narrow (falken ziex) so YMMV

What! I want.

[Mystikal]

Wheels Direct man.

But...why do you want 3mm spacers? No way in hell you could see a diffrence.

[BMW BMXER]

Its just so close right now its scary.

Tire width.

Tirerack's site has the section width and tread width for their tires under the "Specs" link. Select a tire and click "Specs" Under the selected tire are others.

[Skafrog]

225/50/15's RS305's fit and 225/50/15 ES100's fit, with Ronals and euro weaves.
Why are you going up in wheel width? You dont need to.
My front fenders are not even rolled.
