20" wheels on B8 s4 help please

[Ek9max]

I swear I've searched for hours and really couldn't find a definitive answer.

2010 S4. Gonna lower it about 1-1.2" on H&R street coilovers. I think I want to run 255/30/20 tires. Can somebody please help me with wheel widths and offsets that look as flush as possible without rubbing?

20x8.5 +35?
20x9 +40?
20x9.5 +40?

Thank you in advance.

about a 2 inch drop with 20x9 +35 245/30/20 occasionally rubs, tight cornering + hitting bumps+dips in the road at the same time. I'm kind of doubting you have to worry about rubbing with just a 1.2" drop.

Got a pic to see how flush?

[jazza08]

20 x 9 ET32 will rub front and rear with enough of a drop with the slightly stretched MPSS 255/30/20 tires as this is my set up, fender work fixed the front rubbing but doubt I could go wider tires which sucks. ET35 should be right on the limit of a 9' width rim and that tire. There is an entire thread dedicated to this stuff on sticky so go have a look.
This is also a good site to use: http://www.willtheyfit.com/

I'm 20x10 et35 I got 245/30/20 don't got rubbing issues.

Edit: a better pic

seems pretty flush to me:



only rubs in the front since I made it this low, before I lowered it even more, it didn't rub at all:

[Ek9max]

I found a set of 20x9 +38 that I like. 255/30/20. Should be decently flush and no chance of rubbing from what I see.

It seems like 20x9 +40 is super safe and +35 has a touch of rubbing sometimes.... so I think +38 should be perfect.

Yes. I typically would say a 9" wheel ET37 or higher is pretty safe with a 255 tire.

How about a 20x8.5 +34. same 255/30/20 tire.

Thanks Jran76.

Should be fine. ET33 and higher on that setup is typically OK.

[Johnnycash]

dont do 8.5 width on a 20 inch wheel, dont sit right.

Can you elaborate? What do you mean?

[Chuuey]

For reference: 20x10 et35 on 255/30/20 and this was before fender work, before an alignment and before we brought it down more. I am also on h&r coils, I have a very minor rub on the drivers side rear which will be taken care of with a bit more of a liner trim.




Here is the final height.

[Ek9max]

Looks good! I think i'll stick to a 8.5 or 9" rim. I don't love the stretched look with the rim sticking out that far.

Yeh I've never understood that look either. Some ppl go to extreme lengths to get concavity in their rims, it's all subjective.
8.5 or 9' will work nicely with a 255 tire any and of the offsets you've mentioned would be fine.
I would personally go a 9' +38 as it'll allow you to run a 265 tire and extract more performance from the car!

[Johnnycash]

not enough tire on a big rim, and the width is a bit narrow for 20 inches, there is a reason why people are not running 20x8.5 inch wheels on their cars...

[AudBoost]

Please share what brand of rims???

[jazza08]

Please explain why you can run a 255 tire on an 18x8.5 or 19x8.5 but you can't on a 20x8.5? I've never heard anything like this before. Plenty of people run 20x8.5' rims on all types of cars with differing tire sizes.

[Chuuey]

I just post as a reference for what you were asking.

A 255 on a 10" is pretty far from "extreme".

255mm is 10.039 inches.. ie it'd be bang on but most tire manufacturers make "skinny" 255s, especially the MPSS range. So it is very tire dependent. A MPSS 255 tire on my 9' rim is slightly stretched so on a 10' rim, well I think it looks rubbish and doesn't give you a very stiff sidewall if you lean on them. But as you can see above some people even run 245s on a 10' rim so each to their own!

Guys...that is hardly "stretched". I hate the stretched look, believe me, but that car is very properly set up for 255's on a 20x10.

If the sidewall of the tire is not flush with the rim and straight upward then it is "stretching" the tire. Liking that look or not is subjective but if you can look down and see the rim poking out then there's no argument the tire is stretched onto the rim?

Absolutely, man! Tire sizes differ from company to company. The tires I run are narrow for sure. The OP was worried about being "flush" on an 8.5 with a 255. This was merely to give him/her an idea of what you can get away with. Here are some post alignment and fender work pictures to give you an idea of the difference (I apologize for the terrible photos and reflections, its bright and polleny out)

[jazza08]

Wow! Did you cut the fender liner out or something to get that to work? Points for the effort haha

[Race Shooter]

The tire isnt even close to coming to the end of the lip of the wheel, that is most definitely stretched and stretched pretty severely. Its not "needing starting fluid to mount" stretched, but its stretched pretty good nonetheless.

That's a roll and we took the fender liners, cut them like a window and folded them back so I still can pin them back down in the winter months.

Its more stretch than I was initially comfortable with. Its by no means severe, but that's subjective. This setup sees hell roads from NY to MA weekly and havent given me an issue. I don't want to make this into a thread jacked argument, my apologies OP. I'll remove or clean up whatever isn't pertinent to the conversation. But there's your idea of probably the limit of our fenders.

Modphoto has managed a 20x10.5 et40 or 41 if I recall, so that's about as far as I'd expect to see without getting crazy

I can't even really tell it's been rolled so it's a good job :)

That was the goal, thanks!

As you said, it's all subjective. So no, the tyre is not "stretched onto the rim." You make it sound like they managed to put a square peg in a round hole.

This is stretched:



And it looks like doodie.

lol says it's subjective, then states what stretched is like it's a fact.

the irony.

C'mon man. Don't you know my opinion is the only correct one?

[jazza08]

Sorry is it obvious to you they've been rolled..?

for some reason on these cars a 20x8.5 doesnt look right, can you do it? yes of course.

go look through the wheel gallery thread, every single page, and see how many guys are running 20x8.5, thats gotta tell you something.

[Okan509]

pulling and rolling fenders are completely different things. you either don't know what rolling fenders is, or got the two terms confused.

Ah I get what you're saying. I have seen a few "rolls" that end up changing the fender which is why I said that.

[Ek9max]

Ok I think I'm gonna go with a 20x9 +38 wheel.

[Ek9max]

I think I decided on these. 20x9 ET38. 255/30/20.

Pretty inexpensive and look pretty good.

[Henkezinc]

Can you tell me the make and model of those wheels?

Pretty sure they are Verde V99 Axis wheels.

[derek.kritz]
