You are in the Audi A6
What is this discussion about?
Audi A6, Sedan
#643 of 6921 rwish...wheel size. . .17" = harsh ride
Jan 05, 2001 (3:16 pm)
My 1997 A8 came with 17" wheels and 55 series tires, I "plus zero'd" them to 50 series tires and even replaced the stock US A8 suspension with the German "S8" sport suspension -- what little harshness I noticed was minimal (a stiffer ride, better performance, yes -- hardly harsh). Both of my A6 4.2's (one with sport suspension and one with standard suspension) came with 255 x 40 x 17 wheel/tires (the lower the profile, i.e., the number "40" in this case, the harsher the ride). I "dreaded" the harsh ride I was absolutely certain would accompany this wheel/tire combo.
Again, "hardly harsh" at all was my reaction. The lowest profile tire I had even ridden/driven was on an S4 which had 225 x 45 x 17"s and I "knew" my butt would feel every expansion joint and my ears would hear every crack -- cross my heart -- no butt bouncing and -- especially with the Dunlop SP9000's -- very little road noise (on the A6's that is).
I read an article that said lower profile tires (which usually are a consequence of increasing the wheel's diameter over "the stock set up") can improve handling, can make the car look better, can make the car ride more harshly and can be noisier -- and, they can be more susecptible to "damage" from pot holes (because the sidewalls are stiffer). The article said that lower profile tires have become more "viable" as the body and frames of cars in recent years have increased torsional stiffness.
While I do not have an engineering degree, I think this means the stiffness of the sidewall is much more of an issue (with respect to ride harshness) if the car that these stiff tires are mounted on/under is itself NOT stiff.
Audi (and several others) have made huge strides in chassis stiffness over the past few years (must be working with all that aluminium) -- and with my butt and my ears as witnesses, a 2000 or 2001 Audi A4, A6, A8, TT, Allroad, S4 and S8 are not adversely effected by a "plus one" [17" wheel in your case, rwish] sizing of the wheel/tire combination (the 8's even seem great with the 18" wheels).
So while I agree with the sentiments and the principle of dwpc's statement, I believe that you will NOT have a substantially harsher ride. You may notice some extra firmness and you will notice better performance and, depending on the wheels, the car will have an improved appearance. There are some pretty nice Audi wheels -- they will set your car apart, but they are "Audi" accessories (and there are a whole host of cool wheels available from many sources here on the WWW).
That's the way I see it rwish!
Go for the 17's.

for all of your aggravation with the headliner repair, at least it sounds like the dealer was attempting to fix the problem, rather than poo-poo it and say that the problem will "go away with time."
#645 of 6921 17" wheels and Premium radio - Are they worth it???
Jan 05, 2001 (11:16 pm)
Ready to go forward with a purchase of a 2.7T. Curious if anybody has thoughts on the 17" version of the Sport Package (PST) and the Premium Radio (PBS). I have heard mixed reviews on these items. Any comments would be helpful.

I suggest listening to both (standard and dose) systems before you decide. The two systems have quite different sound characteristics. Although the dose system costs more, there are MANY A6 owners (including me) who prefer the sound of the standard system. This is a perfect example of a situation where your own personal taste may very well favor the less-expensive choice.
Here's a recommended methodology: Take a few of your favorite ODs to a dealer and locate a pair of A6 sedans, one with the standard system and one with the dose. (Note that you can listen to the stereo systems without a key; as long as the cars are unlocked you don't need to involve a sales person.) I usually then set the bass, treble, and mid range controls to their "flat" (decent) positions; another logical approach is to adjust them for the best sound, subjectively determined by your ear. Once you've adjusted each system to your liking, it's a simple matter of deciding which sound characteristics you prefer.
In addition, be aware that the head unit is the same regardless of which system you choose; only the maps and speakers differ. With the dose system, the maps and speakers are matched to each other. (The amps provide required equalization for the Bose speakers.) Therefore, you can't replace one (with an after-market upgrade) without upgrading the other; if you upgrade the amps and speakers you've thus completely nullified the Bose package. Bottom line: If you intend to upgrade amps and/or speakers, get the standard audio system.

I see you used the new spell checker (since I assume you meant Bose, not dose and CDs, not ODs). In a post I made elsewhere, it changed hp to up. Such is progress.
#648 of 6921 Spell check!!

Wow, look at that! Yes, I used the spell checker and didn't realize that it changes things on its own!
Thanks for the heads-up, Chris!
#649 of 6921 Premium radio - worth it???
Jan 08, 2001 (10:51 am)
If you want to upgrade the sound system in your Audi -- DO NOT BUY THE PREMIUM BOSE upgrade. Do not even think about it.
There are several after - market upgrades that are better than virtually anyone's "factory" system -- having said that the Audi Bose system is pretty good -- and there is a fair amount of punch added due to the subwoofer in the BOSE upgrade.
The advice above is best, take a CD that you know VERY WELL and listen to it (from the same posistion -- say, the driver's seat) in a Bose and Standard system equipped cars -- back to back (and with the windows rolled up). Remember that the louder system will appear to be "better" -- set the tone controls for your "best" sound and then crank the volume to the same levels on both cars -- you may find the Bose just isn't worth it -- especially if you mostly listen to the radio and moreso if you mostly listen to AM radio. Much FM radio is so compressed that even it doesn't have much in the way of very low or very high frequecies.
Also there is a phrase, that does have its roots in truth -- "no highs, no lows. . .must be Bose."
This phrase came from the original Bose "direct reflecting" loudspeaker which used, as I recall, 8 identical drivers facing the same direction and one "on the other side" -- the speakers in this array were all so-called midrange speakers that produced highs and lows via an electronic manipulation called "equalization." Many Bose systems, today DO have tweeters and woofers -- not just mid-range, but this is just a bit of the very deep Bose root. Mostly a story -- not too true today.
Take a test listen is still the best advice.

I am interested in adding CD Changer to my sound system for A6 2000 model. Are there any suggestions that are less expensive than the dealer installed model.

Quite a few folks have bought their Audi CD changer from Clair via mailorder for a few hundred. Like, 40% to 50% of new list. URL included.

Yup. The OEM changer is $300 from Clair. You can easily install it yourself in about 15 minutes, and you'll have full compatibility with your factory head unit. If you want a changer, this is the only way to go.
