20x10 ET38...will it fit? What size tires?

[FlashA4]

Looking at wheels with these specs, but I've read a bunch throughout these threads that have me a little nervous about fitments once you get up to the 20" range...
Anyone here with experience with 20's bigger than 9"...Tire size recommendations to keep from rubbing? ET seems about right.
Thanks.

i have 20x9.5 et 20 and 22 on b5 s4. it has been widened by pulled fenders and a fender roller. good luck i wish i could help you. your best bet would be to take a wheel off and physically measure

[Checho]

yes it will fit.

get a 225/40. My friend with the IW B8 is running 20x10+28 and he's running fine on rolled fenders. At +38 you'll need to roll a tad bit but it should be too bad.

Oh hey thats me lol. Your good Flash, its going to sit 10mm farther in than where i was at. It all depends on your tire size though, if you get a chunky tire you will rub.

[Wolfs9]

You running 225/40 ? I thought it was 235/35?? Grtzz

[Nght&Day-B8]

It is 235/35, im saying its me in reference to the wheel size.

[Blake P]

I think 245's will work and not look quite as stretched.

[Nght&Day-B8]

They might with a +38

[blackavant]

Yes 245 will work with +38. I have 245/35/20 on a 20x9 wheel et+35. The tires where rubbing on the carpet by the fender so we had to cut some of the carpet on the sides and now no rubbing at all. I also have h&r oe springs on.

You sure about those tire sizes? 35 profile on 20's seems kinda tall, definitely larger than the stock diameter.

[audi til I die]

245/35/20 IS tall.

235/35/20 might work with a stretchy tire because the stretch takes away from sidewall height. Not something i'd drive everyday but will look pretty good

I've ran 235's on 9.5's and the stretch is definitely noticable, but not ridiculous.

[blackavant]

245/35/20 is tall. But I did not want to sacrifice the ride quality and the tire also closed the wheel gap that I had. The difference between my stock 255/35/19 and the 245/35/20 is only 2.73% and the speedometer reads 2 mpg slower. I am very happy with ride quality.

you can run 20x10 et38 with 255x30-20........they will be sweet on a B8. Just pick a normal tire, and not a super wide square one. 20x9 et35 with 255s work, and the extra 3mm et will offset the increase in rim width, since the tire will be mild stretched.

For the record, he does have some rubbing on that setup... and that's WITH a tire that has a forgiving sidewall. I honestly think 10's will only make it worse.

[L0U]

there is an avant running 21x9.5 with 1" taller than spec tires.

the b8 with 20x9.5 et33 is on 235s ande has room for 245s, so 20x10 et38 on 255s would be about the same. you can allways machine 2 or 3 mm off the back of the rim if needed.

depends on your drop and camber.

9.5" ET33 is the same as 10" ET39 in relation to the fender. Add an extra 10-20mm of rubber and I think it's begging for problems. Machining the back pad of the wheel is not exactly as easy as you make it out to be and should only be used as a last resort. No matter how you slice it, 255's on 10" ET38 is gonna be a tight squeeze and there's no way I could sit comfortably behind my computer screen and suggest it to someone without the disclaimer that it's very likely they will encounter fender rubbing with possible (major) modification needed to make it fit rub-free.

[L0U]

at stock ride height we have a b8 running 265s on 9.5 wide et37, it pokes about 4 to 5mm in the front. tire rack runs with 20x9 et41 and 265s on b8s.
http://www.tirerack.com/wheels/resul...ige&sort=Brand

that rack setup is about identical to the stance of 255s on 20x10 et38

if dropped on springs then it will need work. agreed.

[Blake P]

If we assume that the TireRack setup actually fits rub free (which is all we can do because nobody has actually seen that exact setup on a B8), the outer edge of the rim would be equal to 10" ET54. Since you're suggesting 10mm thinner tires, take 5mm of rubber off each side and we get to ET49. Even if we assume he'll get an extra 5mm of clearance due to slight stretch on the wider wheel, that only gets us to ET44. I still think 245's are a safer bet and 255's are asking for trouble.

EDIT: As a matter of fact, PESAPC was running 19x9" ET43 with 255's and even had some light rubbing at a height I'd hardly consider low. Just keep in mind there are so many factors to consider when suggesting wheel/tire setups and I'd much rather stay on the safe side than tell someone what might fit and have them run into issues and blame me.

[L0U]

235s on 9.5 wide et33. He measured and claims that 245s will work, I'd say 255s in back would work even.
a 10" rim et38 will poke 1.4mm further out than these rims. So there will be rim poke.
A 235 on a 9.5 is the same stretch as a 245 on a 10" (looks too stretched to me) your setup would be identical to this look if you ran the 245s on 10" et39.4, so et38 would be nearly the same.

If you think this picture has 6.4mm of room extra, then the 255 will work. This car did not have camber or fender work. 5mm can be taken up by camber, and 5mm with fender roll.

I think if it were me ideally, Id do 20x10 et40 255x30-20, then use a 2 or 3mm spacer if there was room. It is allways safer to go deeper and use a spacer. If the rim couldn't be machined 2mm, and it was a style I really wanted, I'd put them on and make up the extra few mm with camber and fender work.

It would be a killer setup that has not yet been done, although rotaform has a 10" setup it has been thinking about doing.....they did say 10 will fit.

[FlashA4]

I appreciate all of the back and forth dialogue between everyone in this thread.
I got some good information from this for sure. I really dont want to go crazy trying to stretch tires. This will be my daily driver, so Id rather stay on the safe side of things.
The same rims that I am interested in also come in 19"x9.5" ET 35. I think this would be a easier route to go. I just wanted to weigh my options.
Btw, Im also about to install H&R Sport Springs.

[L0U]

I'd actually do 245s on the 19x9.5 et35s, the 255s will need work to fit on et35 and 9.5 wide. sould look great though with the 245s

+1. My ideal setup based on rough measurements I've taken on my own car is 19x9.5" ET36 with 245/35/19.

[FlashA4]

Ideal in terms of wheel push to the edge of the fender without spacers as well?

Again...thanks guys.
I just watned to throw it out there real quick about the 20's, but Im definitely now settled on the 19's...
And on top of that i learned a bunch about tires, sizing and stretching. all in all a good lesson.

[Higgseye]

Guys, I have just bought a 2010 B8 Avant and from what I can tell, 20's are good to go as long as the offset accounts for the increased wheel width, from measuring up the space available under my fenders (we call them Arches in the UK) it seems that the biggest issue is going to be with the front wheels potentially rubbing the fenders.

I am investigating 3 potential setups as follows

255/30/20 on 20x8.5 rims with et+35 (i may however go with 245/30/20)
255/30/20 on 20x9.5 rims with et+45
255/30/20 on 20x10 rims with et+42

I have H&R height adjustable coilovers ready to fit which will drop the car all round by 30-60mm (it's non-sports suspension at present), do you think I could get away with any 1 of these set ups with out rubbing the front fenders? I will only drop the car by 30mm initially and if no problems can look to bring it down further once it's all settled.

with the ET35 and ET42 options I could have an extra 3mm shaved off in order to sink the wheels in further and I also think there may be room for some spacers in the rear. I have a really good idea about the wheels I want to fit and they come in the 20x10 et 42 measurement, the thing is I would have to order them from the US and if they are gonna rub-a-dub-dub then it'll be an expensive mistake.

I will also add that although I would prefer to avoid it, I am not completely averse to rolling the fenders!!

Comments and assistance massively appreciated!!

[Antsa4]

I am running 20x10 et 35 with 255/30/20. I rolled the front fenders. I only have a slight rub over large dips in the rears. I ran this setup all spring and summer with no problems in CT with some crappy roads. I am also lowered on coilovers.

I know this is an old thread but what did you decide rims size wise.

[AudiTeKDK]

Well well... I started reading this thread and went with 20x10 et35. 255x30 tyre's. This setup sticks so much out from the fenders that I had to go to et45. So anyone looking for a 20x10 should keep this in mind. At et45 the rim sits 1-2mm from the wheelspindel, very very close. I would bot recommend. 20x10 will fit. But barely.
