TT wheels - fit an A2?

16" TT wheels fitting on A2

well I decided in the end to put 205 45 16 on the new 7 spoke TT wheels (7j ET31), mainly because I found a great deal on uniroyal rainsport 1 tyres, which I have had before and found excellent and have a fantastic write up.
bought 4 from jettyres online cost £220 delivered (£55 ea) and £30 to fit all 4 at local garage.

I was a little doubtful at first and was looking around for 195 50 16 but could not find a better deal than this.

see attached photos, not sure what you think but I really like them and the ride is very good

cheers

The best way to post photos is to put them onto an online photo host and then post a link to them.

If you don't have an account with one of these hosts, mail your photos to me mike-at-gothic.plus.com - replace the -at- with the appropriate symbol) as a regular attachment and I'll put them up for you.

Thanks Mike, just to confirm: the tyres are Dunlop SP Sport 225/45 ZR 17's.

And they are now for sale at £250.00 for four collected.

I have now had the original wheels back from the refurbishers.
 
I’ve fitted 7 spoke TT 16" wheels with 205/55 tyres, Offset 31mm. No rubbing issues unless you take the speed bumps on the roads where I live at 30mph, you get some rubbing as the car bounces on the back wheels, taking the bumps at this speed was impossible with my old RS 17" 205/40. et off set 38. the car wheels would be squared and you would have a serious back injury.
The added benefits which I’ve noticed is the wheel offset pushing the wheels a further 7mm outwards which helps clear the raised edges of the speed bumps which was the reason for me to change wheels, this outward 7mm I guess gives a squarer stance on the road which I assume off sets the raise in the overall height of the car, which as increased by 20mm. The sticking out of the wheels is no more noticeable then my old RS 17".
It’s the wife car and she’s carrying the kid in the back hence why I don’t want my Kid brain damaged by the speed humps but also concerns over the handling of the car having made the wheels size change. There a slight increase in car height which caused me concern (looks like a mini Q7 !!) as such I took it to work with me for the past week that’s 100 miles a day across some of the toughest roads in England: M67, M60 M62 A57 snake pass, A628 Woodhead pass. I’ve throw the car around in all circumstances knowing these roads like the back of my hand.
Cornering is no different there is no under steer or over steer or deviation from my old RS17” 205/40 wheels granted the car tilts ever so slightly more in the corner but to nothing detrimental and the grip on the road is ever bit as good as the 17” RS.
Rubbing of tyres did occur if the car was seriously jolted going over a extremely bad pot hole or excessively fast over speed humps. Using a lower side wall tyre would remove this say 205/50 or 205/45 but I’m happy with the 205/55 for now. horses for courses.
Emergency stop; I’ve slammed the breaks on a few times and the car response is spot on no indifference the traction control works the same.
The Ride quality is far far far-better its takes pot holes and the dreaded speed humps with ease in comparison to the 17” 205/40 also far better then a set of 15” 195/65- I first tried on the car.
Also checked the Speedo against my sat nav and it spot on no difference in the speed although the wheel diameter is more.
Some members have pointed out that using over size wheels in Germany is illegal, the only aspect to doing this in the UK is probably an insurance issue in changing the car from its standard format which could void your insurance if you fail to disclose such.
I’m leaving the wheels on. I feel overall the cars performance in my opinion is far improved and the style is also improved too.
Its horses for courses, the wife has to endure 2 miles of speed humps. I set out to make the ride more tolerable which I’ve achieved with these wheels and hopefully the wife will not get sneered at, road raged, cause tail backs, put under pressure to go over speed humps faster then the car can cope with.

I decided against the 205 55 as I was sure they wouldn't fit with the rolling radius so much different (3+%) so went with 205 45 and the difference is marked. I have 4 part worn 205 55 michelin tyres if you are interested by the way (I am not far from you)

I agree they look smart, and the offset actually helps, although I am a little concerned as I hear a slight metal on metal noise on offside front when I go over a large hole/dip in road, hope it isn't a spring!

But I still like the look of my other A2!

I've stuck with the 205/55 tyres as they came with the wheels and are brand new, sadly no nice TT centre caps with them had to use an old set as on my photos as my RS ones would fit correctly. The plan was to go to 205/45 tyres once I was sure the wheels would fit, but having tried them on I stuck with them and will give it 3 months to see how it fairs so thanks for the offer of the tyres but I'l wait. I'm after the Original TT caps now as like yours. Ebay sell the fake chinese make so options are limited- say buying a second set of wheels to get the caps or direct from Audi which is just as costly.
I have no issues with rubbing, say what I already mentioned, so your issue may be something else and may be worth investigating further. Your 205/45's look a nice fit and I may go to this size once these tyres are worn which could takes years at the back or months at the front - we will see.

Hello livermanx,

these wheel sizes both

195/65/R15 and 205/55R16

are extreme solutions for A2, and are - as erstens already pointed out – entirely illegal over here.

Both wheel diameters by far exceed Audi’s specs statically. And please don’t forget their dynamical behaviour at high motorway speeds.

Apart from that I would never recommend such big wheels because:

- very high unsprung mass:
  • - your A2 becomes a “dog“
    - mpg definitely does decrease
    - damper effectiveness suffers clearly because unsprung mass does exceed their application range
- in general there might be potential problems with ESP activities in (critical) driving situations no one can predict.
- wheel rubber must never contact anything else than the road surface.

If your wife has many speed bumps to deal with during daily routes, the by far smartest solution for this issue would have been Koni FSD dampers with for instance 195/55R15 wheels. Not only comfort is increased but also handling and safety while applying FSDs.

So the main reason for poor bump stop handling generally are not the wheels but the stock suspension A2 setup! Please check out the corresponding suspension related threads in the “Modifications“ rubric.

Cheers

I don't agree that the TT wheels increase your fuel consumption. My car was returniing a constant 51 MPG and continues to do so despite fitting the bigger wheels.
 
In general, Schnelletrecker is right - increasing tyre size does increase consumption.

It's partly to do with the extra mass being driven around, but mainly to do with the increased rolling resistance, due to more rubber being in contact with the road.

This varies with tyre brand and so you may be in the position of having TT tyres that, although wider, gave the same, or a lower rolling resistance than those fitted on the A2 wheels.

Cheers,

Mike
 
Hi

Sorry to hijack the thread but can anyone confirm what the standard size tyre is that should be fitted on an A2 sport with the 17" 9 spoke alloys as I think mine is running with the wrong size tyres put on by the previous owner.

Also, has anyone got the part number of the above wheels wheels and what offset as Im begining to wonder if my car has the right wheels fitted.

Thanks

I can't give you the part number as I've not got access to the parts catalogue at the moment.

However, the correct tyre size, as fitted at the factory, is 205/40 R 17

Thanks for that.

Mine has got 205/45 R17's!

I hope that it wont make too much of a difference?

If anything, it will improve the ride quality. I know that a few members have replaced their standard tyres with this size.

conclusion RS17" to 16" TT

I have run my A2 with the 16" TT wheels with 205/55 tyres for 2 weeks and the issue of rubbing has been an issue on the back and when the front is on full lock. My model is a SE with sports package. Whilst the ride was certainly improved due to the height of the tyre wall and the TT off set difference of 7mm which throws the wheels out slightly creating a wider rider the rubbing issue couldn't be ignored. So I have put 195/45 tyres on which are one of the recommended tyres specs. The other option for 16" is 185/50 but these are far more expensive due to the fact that this size rare on 16" wheels.
The ride is now standard but its an improvement on my RS 17" wheels using 205/40. But as mentioned previously I used 15" wheels with 195/65 and had no issues with them except for the fact that my wife didn't like them and as such there wasn't much on offer in the 15" range that would possibly fit these 15" wheels are now in the ownership of a member who's read this thread.
To adjust the suspension as some have pointed out to improve ride quality is a costly choice and could also invalidate your insurance just as much as changing you tyre recommended spec if you fail to tell them.
My conclusion is the TT wheels are a better option then the std SE wheels as the 7mm per wheel (14mm) off set gives a bit more wider ride, they look better with the extra spoke and as such are a stronger wheel over the SE and RS std wheels. Also they seem to come up on ebay as their the std wheels on the TT to which the owners get ride of as they up grade and no TT owner wants them as such gives the A2 owner a cheaper alternative up grade at a cheap price. I paid £150 for my set which had 4 New 205/55 tyres on them I have sold the tyres for £90 as such a new set of wheels cost me £60! With 4 New Avon 195/45 tyres from www.Tyre-shopper.co.uk fitted at National tyres cost me £240 as such £300 total and a lot more knowledge on the technical aspect of A2 Wheel .
