Hi,

first of all in this case you would need rim spacers definately - 10 mm per wheel to get the offset right.





In fact there are only two A2 people so far who long-term fitted 19“ rims in the past – located in Norway. Please do a search for vidum here in this forum. I suspect both are pure city cruisers because they stated: „Everything for the beauty!“



In Germany however the TÜV does not allow such wheels on any A2, because:


1. Even after removing the inner wheel arches you will need a massive amount of additional bump stops to keep the wheels turning freely in every dynamic driving situation.

But very restricted suspension travel can also lead to very dangerous driving situations potentially (abrupt oversteering, massive loss of grip and traction, etc...). Additional bump stops do always ruin the suspension settings (interplay between spring rate and damping force characteristics)!



2. Furthermore the wheel perimeter is way too large – the speedo has to be re-calibrated.


3. Unfortunately, the unsprung mass will suffer severely in case of (even lightweight) 19“ wheels.


4. The inertia of 19“ wheels will have a very negative effect especially on petrol A2s. Their limited available torque will suffer noticeably. So you should factor in the potentially excessively increasing fuel consumption combined with very low acceleration performance.


5. Last not least you will have to restrict the steering angle due to the large wheel perimeter - monster turn radius guaranteed. :eek:




The list of disadvantages of 19“ wheels is large – so why not going for:

7.5x18ET35 to ET25 plus 205/35R18 or 215/35R18

8x18ET35 to ET25 plus 205/35R18 or 215/35R18

With 18" wheels you don't have to bother with above listed disadvantages. You can even use a nice 30 mm lowering (with the highly recommended Toyo Proxes T1-R RF FSL in 205/35R18 81 Y ZR) without problems (after modifying or removing the inner wheel arches).

I'm sorry - I cannot help you as there will be rubbing issues for sure - with the 215/35 tyres, you're looking at a diameter of 633mm, when the safe maximum is 615mm (stock is 595mm).

All I can say is much as I like a modded A2, this is something I wouldn;t even consider.

Cheers,

Can you clarifty the comment on wheel arches. Are we talking front arches or rear arches, and is it required for the 215/35R18 only or also for 205/35R18. And what difference does the offset make to this as typically additional offset will give better clearance to the back of the arch. Also do the arch liners have to go if you don't also lower it?

I am about to buy some 18" wheels for mine so I want to make sure I am fully appraised of the requirements

[Schnelletrecker]

Hi,

we’re talking both the front and the rear inner wheel arches made out of thin plastic. Of course you can preventively remove these inner arches completely...

But first try either the heat gun and/or the dremel tool.

If using the latter, just remove only that amount of plastic that potentially will be contacting the rubber. If the horizontal flange itself has to be reduced or removed in order to supply sufficient outside wheel space, this should be done with the dremel also.

You can combine the highly recommended Toyo Proxes T1-R 205/35R18 (being relatively narrow for its size) with a 7, a 7.5 and an 8“ rim width. In each case selective modifications of the inner wheel arches are required potentially, as long as you keep the offset within a certain range:

So this range should stay within ET 35 to ET 30 to minimise the adaption(s) of the inner arch per wheel.

Please avoid 215/35R18 tyres in case of lowering – we don’t want to install additional bump stops, do we? :)

One more clarification - how do the 17" sport alloys fit then without modification, as they are presumably using 205/40R17 which has the same diameter as a 205/35R18. Are they using a particularly low offset?

[Schnelletrecker]

Well, compared to 205/35R18 the 205/40R17 tyre size comes with a shorter perimeter and a lower static height.

Also the offset of the 7x17 standard S-Line sport wheel is ET38.

So the stock 7x17ET38 plus 205/40R17 wheels do fit without any mods even with the mild Audi lowering of 15 to 20 mm.

However, because most people mounting 18“ on an A2 take 7.5 or 8x18 rim dimensions, an ET of 38 would be too close to the suspension and to the wheelhouse trim. For that you have to reduce the ET number appropriately when using wider rims/tyres.



Extreme example at minus 50 mm of lowering:

Front: 7.5x17ET25 plus 205/40R17 plus modified inner wheel arches

Rear: 8.5x17ET20 plus 225/35R17 plus removed inner wheel arches plus removed horizontal flange of the fender




Both the rim horn and the tyre shoulders must feature at least 5 mm of clearance in all situations!
