After speaking with two Tire Rack professionals, I am being told 245/40-18 is the tire to go with (for my new 18" wheels). I have a stock '06 B7 A4 3.2 quattro (auto). From what I understand, Audi used 235/40-18 on the S-line. But the S-line is lowered a bit from the standard suspension. I want a wheel which feels out the fender well nicely, but I don't want something that rubs or looks like Grandma's grocery-getter.

I checked out the B8 Audi and found it uses 245/40-18.

Looking for some help here before I drop at least $600 on tires.

Thanks!

If you don't have the S-line package you can still have the sport suspension. If you don't have either the sport suspension or the S-line package you're better off not getting 18s as your car will look like it has some sort of lift kit.

Yes to the sport suspension (I think). I have the 5 spoke sport wheels (with 235/45-17 wheels), so I am fairly certain I do. I purchased the car used, so I am not certain.

Lets assume I do have sport. What would be the recommendation.

What is the width and offset?

Here is 245/40/18 on 8" s-line wheels ET43

As you can see, 245 tire sticks out pretty far on 8" wheel. Keep in mind this particular tire has a rim gaurd and run a little wide. If it's an 8" wheel, I'd go 235 if 8.5" I'd go 245.

Also, if the wheel has an aggressive offset, for example x&lt;ET35 you might rub with 245 under hard cornering. More pics, just click on the sig.

Big thanks for the details pictures!!! However, I am confused on your recommendation. Per your pics, it appears the 245 tire sticks out LESS on the 8" wheel vs the 8.5". Correct?

Here are the wheels I am seriously considering -- the S5 replicas. ET is 45.

Let me know what people think.

Thanks again!<ul><li><a href="http://www.powerwheelspro.com/shop/product_info.php?cPath=21&amp;products_id=41&amp;o sCsid=0f0490eb310dd93eaaa0e675d1e6e7c3">http://www.powerwheelspro.com/shop/product_info.php?cPath=21&amp;products_id=41&amp;o sCsid=0f0490eb310dd93ea

Hey addict, you're pictures inspired me to get the RS4 reps in 18". Thanks a bunch for sharing!

If your goal is to fill out the fenders you'll need some spacers. An 8" wheel with that offset will fit much like the stock s-line wheels I posted. Also make sure they will clear the brakes before you purchase.

I'm running 245s on my summer setup with my B6 sport, no rubbing.

I had your setup 245/40/18s and after 12,000 miles the tramlining was unbearable. Alignment and full suspension inspection revealed no problems. New tires cured it. Went with Yoko S-drives this time.
