That’s very small but I can’t see why they wouldn’t fit over the brakes.

I have read about 14" wheels on A2s but wanted to check with the experts on here first. Thanks for the reply.

Hi @Jock
I am not an expert though the tire tables are quite factual
Your 175/70 R14 are not smaller but actually 1.16% larger in circumference... relative to the tire size Audi based their homologation on, 165/65 R15
This will lead to:
Your A2 will be approx 3mm higher
Speed will be displayed 1.16% faster than reference if rpm is the same.
CV/front area value will see a very minor increase, due to the increased height of your A2
175/70 R14 will give you much increased sidewall height and this will give a softer ride.
These 175/70 R14 will in general also feels like a bit softer during curves too. (Brand/modell, load index and speed class will matter)
If you have a chance to try the rims on your A2 before you pay them, I would have tested a front wheel and checked the clearance relative to the caliper. The different rim design vary a lot so do not take the assumption that since one 14" design fit, others will too...
Arc clearance will depend on the width of your rims. The ET you mention will be ok unless rims are wider than 6.5 inch if you have standard suspension and no bodykit.
Visually, your 175/70 R14 will look like the wheel to the right... The left one is the referenced 165/65 R15 (195/55 R15 will look the same as one other example)
The best tire and rim tread I have spotted in here is:
I hope this can be to some help ?
Cheers

The definitive tyre / wheel size thread
Budget isn't really a problem. It was more to see what the difference was between the 3 different sizes? I.e. as you say, if 185/50 isn't available, then 195/50 is ok, but what are the differences? Compared to the 185/50R16 size, the 195/45R16 size has an outside diameter that is a little bit...

Thanks Dieselfan, that's a great help although the wheels are 175/70/14. I am concerned about rubbing on full lock and possibly unsafe cornering. I assume they will be extra comfy but don't want any bounciness. I agree about the definitive wheel/tyre guide, it is a great source of info. Thanks again

They are very unlikely to rub at that ET but the cornering will have more roll, the quality of your tyres will have a massive effect on this also

Sorry for the typo, luckily the calculations are based on correct dimension ?
In general I wonder about getting too hung up about a few millimetres in size between wheels. As a new tyre with 8mm tread depth wears to the legal minimum of 1.6mm the ride height wil vary by 12.8mm. A wheel 3mm larger than standard will be back within normal range after a while.
Or have I got this wrong?

My only intention was to present facts, and let @Jock decide for him wrt what's important or not.
"appels & bananas" - if one start with same tire brand, same modell, same car, same usage... but different size... it will still the same 3mm ish differance in height throughout life...
(please try to see the humor in this...)dieselfan
As we are usually interested in how the wheel+tyre fill the wheel arch, I just assumed ride height was the diameter of tyre hence my 12.8mm, but if to centre of wheel then you are correct at 6.4mm.

The rules state two starting points, as I've understood it: no more than 3% nominal circumference difference, and the speedo must not underread.
That's the smallest common denominator. German rules are way stricter, they are quite lax here, similar to the UK but with more references to the coc.
But the principle holds: normal 205/40r17 circumference is around 1860mm. Wear will drop it down, so that's the maximum.
So if your nominal new is within spec, they will stay that way over time.
I agree on floaty ride, and that the wheels may or may not fit; they should clear the calipers without issue but there's no guarantee.

I am running 14 inch steel wheels. They are the standard Polo fit and fit the A2 as well as they share the same calipers and drums. The Polo of the same vintage as the A2 also can have 15 inch alloys as a smarter option, 14 inch steels were just the base option but they fit the A2 fine.
No worries, my comment was very general and not specific to your post and I see and appreciate the above humour. I enjoyed the humour of your initial typo and I made a typo once using a tyre comparison website and got a wonderful image like below. I noticed something was very wrong, this speedo is definitely unacceptable!My only intention was to present facts, and let @Jock decide for him wrt what's important or not.
