Slightly different question as to what has been asked so far so here goes:

My '11 has the 10 spokes. Looking at ordering some new 19's.

If going to a 9" wide wheel, what would be the "ideal" offset so as to avoid needing any spacers and have the flush look?


I see that many use slightly bigger spacers in the back, so if I look for all 4 wheels to be the same, I understand I might still need a 5mm spacer for the back. Most say 20/25, some say 15/20, either way if I get all four the same, I'll probably need 5mm for the back. That I can live with.

Using the willtheyfit tool, I really need to know how much backspacing we have available before the rim hits the suspension.

From looking at the tool, anyone with a 10/10.5 inch wheel has to have less clearance on the inside than stock or they would have tons of poke.

Hi just wonder! I have a A5 Sportback S-Line with S-Line sport suspension originaly from Audi (S-Line) lowered 30mm, and the car was delivered from Audi with 19" 255/35 S-Line wheels. But will this wheel also fit on my car???

I want to change the rims and wheels for my 2008 A5 couple. The new wheel parameter is 18 inch, 9j, ET30. The tire I use is 18/40/245. Do I need a spacer or it has been aggressive enough?

Hello I know this thread is old but I didn't want a new thread for this question. I have a 2013 A5 with 19s currently on it. I need some winter tires due to being here in Colorado. Would 16 inch wheels work for my car?

I haven't measured it, so this is only a guess, but I suspect the smaller diameter wheel would foul the the brake caliper. I know that 17s are okay, but the 16s might be a bridge too far.

Hey I'm a tire noob and had a question about winter tire fitment. I own a 2013 Audi A5 S line and currently have the stock wheels on which are 235/55/19 18 x 8.5 ET32

I just picked up winter tires that are 225/50/17 17 x 7.5 ET35. Will these be okay on my A5? I used an offset calculator and it said my inner clearance will increase by 10mm and outer position will retract by 16mm. Can somebody please help me out

You sure those sizes are correct?

Assuming those dimensions are correct apart from the 235/55/19 should be 235/55/18... then they will physically fit (assuming 17" is big enough to clear the brake calipers) BUT you will be out on speed by 8% which is WAY outside of the +/-2% normal - 80mph will in fact be 73.5mph. You may also invalidate your insurance with such a big differential. There is no way I'd run with those tyres/tires at that differential....

Having said that, the current stock tyres on an SLine A5 is 245/40 R18 - which is 9% smaller than the 235/55/18's you've quoted above which makes me suspicious. Current stock 19" wheels are 255/35 (and for completeness, stock 20" are 265/30's....)

Hi Geir,

9 X 20" ET 29 265\30R20 Should fit fine as I have them on my A5 3.0tfsi Sline Black Edition. This came directly from Audi.

My additional question to everyone would be could I fit 275\30R20 to the 9Jx20 ET29 (p/n AUD 8T0601025CM - 8T0601025L1H7 -20" Audi 7 Double Spoke Wheels) and would this fit under my wheel arch? As this is the OEM size for the RS. The 265 tyres cost waaaaaaaaay more than 275 (in my current location) as 275 is more of a common tyre.

Your help would really be appreciated.

Thanks,

Max
