maximum tire size without rubbing
 

Hi all, apologies if this has been covered, but I tried searching to no avail.

As I wait for my car (hopefully this week) to be delivered (:D)
I'm planning ahead--I have a set of tires (235 50 18) that are brand new on my aftermarket wheels. I would like to put these wheels on my new 2.0 quattro, but I'm going to assume these tires are too big...(FWIW: I know the sport package has 18" wheels wrapped in 245/40 tires...)

Are these tires going to rub against the fender? Or will they simply give inaccurate speedo readings...those I can live with...rubbing, not so much :p

thanks!

I'm running 255/25/19's with room to spare. You would be fine. The speedo would be off by about 2 mph at 60. (Your speedo would read 60 but you would be doing about 62.)

thanks for the info, ben

do you have a picture up anywhere I could check out your wheels ? :)

Sorry for the late reply. Been a real busy week. These are the 19" A5 S-Line wheels on my A4 before I lowered it.

235/50/18 is 5% larger than the largest factory wheel & tire setup on the A4 B8 so I wouldn't do it.

The person suggesting that he's running 255/25/19 (which is an obvious typo for 255/35/19 given the photos and lack of an available tire in this rubberband sizing) is running an approved factory sized tire. 235/50/18 is larger in diameter by 1.25" than the 255/35/19 setup.

Also were your wheels from another car like a previous Audi? If so, the center bore is different and won't just bolt up. At best you'd need an adapter.

If neither the rims nor the tires are really right for the car, I'd sell them and get something intended for this platform.

Is it Sline Model ?

Sorry. I did make a typo. My tire size is 255/35/19 as suggested. The 1.25 diameter is pretty significant but you can always bolt them on and just try it out. That is assuming that you were aware of the new bore size. But, if that isn't the case then JasonR is absolutely right. They just won't work.

No, mine is not an S-line.

Hey I have a sport package avant with audi s5 sport wheels which are 19". They have 255/35/19 tires. Other than a little bit poorer fuel economy, there is only slight rub with three passengers.

The offset of the S5 wheels and A4 are quite different. 255/35/19 is a genuine factory tire size for both cars, but your wheels were not intended for the A4, so they're sticking out a bit more than they should. They probably look awesome but as you've found, there is a chance they'll rub, especially when carrying a heavy load and/or if lowered.

And this too has nothing to do with the OP's question, but I guess that's par for the course, right? ;)
