[s-cars] Tire size for '01 A4

[calvinlc at earthlink.net]

Taka,

Actually, starting in 2002 it was 235/45/17 on a 17x7.5 rim.  I was as
surprised as you that the optional tires on an A4 were bigger than an S4 in
2002 but if you would like to verify check out the model guide on Audiworld
for any year A4 from 2002 and up.  I know this is the case because I swapped
one tire off a loaner one time to my UrS to make sure a 235/45 would fit :)
I don't know with 100% certainty that the fender wells are the same for
1996-2001 A4's as they are for 2002-up.

  Calvin-
  Factory setup on a B5 A4 is 225/45R17.

  B6 and B7 use 235/45R17.

  Maybe that's where you're confused?

  The gearing and the speedometer are going to be off if you run a much
taller 235/45R17 on a car designed for a smaller rolling diameter.

  Since the bodywork is different, I don't think you can necessarily say
that whatever works on a B6 will work on a B5.

  As I said before, the tire size isn't the only factor- wheel offset and
width play into this as well. A wider wheel that more fully supports the
tire is more likely to rub because the tire will be a lot more "square." A
tire on a narrower wheel has more play because the tire will be more
"rounded."

The
    sport package wheels on an A4 are equipped with 235/45/17's from the
    factory...maybe the offset is different but all the loaner A4's I have
    gotten in recent years had these tires on them.  They were 7.5 inch rims
for
    width.....I think 42mm on the offset but don't quote me on that.  Maybe
the
    '02s and up have different fender-wells....I don't know.  One of my
friends
    just put 235/40/18's on his '01 S4 and they work fine as well.

    0.29" higher, 1.2% gearing . Darn near irrelevant.

    but I have heard that some brands of 235/45 DO rub, so caveat emptor!
