Hi. 

 

I am the proud owner (or my wife is) of a 2015 Audi A4. We would like to change the wheels since the one we got had horrible 17" wheels and we would like 18/19". Ideally genuine but budget restrictions may mean 3rd party. 

 

How do I work out what are compatible sizes? I thought I could use one of the popular websites and it would help me work it out, but that doesn't seem to be the case.

 

Any advice would be appreciated. 

 

On my S4 I had 19" Wheels but I think they were too wide as when I turned the wheel hard they would rub.

Normally I'd suggest getting a set of round ones but if you like to be adventurous you could try oval or square ones tongue-out

 

 

 

I'd give mag n turbo a ring they should be able to sort out sizes for you

I've got a 2010 A4.  I seem to have 19" alloys and have been told the tires are almost too wide - but it has the effect of filling the wheel arch - and IMO looks great.  

 

I've not had to replace them yet (they're nitto invo  255/35 ZR19).

Hey,

 

I would suggest you keep an eye out for genuine wheels only. Some after market wheels are cheap knock offs made in china based on another after market style or brand style. Stay well clear of the Replica wheel category.
My dad has some 18" S4 wheels from his 2014 S4 we replaced with 19's. They need to be re furbished (sub $300) or do it yourself.
If your interested ill find a picture. They are 18x8 et 46 i think, Same PCD as your car.

 

Cheers

A question I ask folks looking at this is why? is it aesthetics? Grip? or just because?  Going for a bigger wheel you will need to go for a lower profile tyre in order to maintain factory set gearing and speedo etc. This will compromise comfort and on our appauling road surface that is already bad. Fuel economy and power may well be affected.

 

If you go for overall in crease in size that is rim and tyre you are going to have to do changes such as speedo. Suspension travel will need to be check as will ASB, ESP, Brake assist and so on. The gear ratios will be affected as will power and economy, I would definitely check with an Audi Dealership regarding this.

Here is the S4 on the 19's. They are the "Peeler style" Now you need a wheel with a high offset to clear the brake callipers but not too much that the wheels stick out side of the guards. Thats why i suggest OEM wheels only as the fit perfectly.

We upgraded from the 18" wheels that came on the car. Finally found an image.

 

The 19" wheels grip well better, The gearing is much better around town, Rolls over bumps a lot better, Looks 10x better.
If you stick to a factory fitment for your car your speedo will still be with in its calibrated range and same with your gearing. There is no different between an a4 that comes on a 17" and a 19" from factory.

 

Aftermarket wheels are the bread and butter of car dealerships. Wonder why every new ute comes on magz ow?
They make a killing on them, They buy the cheapest nastiest ones on the market and sell them for double what they purchased them for.
