Tires will have 6/32 tread on fronts, 10/32 on rears. Any problems for the quattro system?
I might pick up a pair of used tires with 10/32 tread to go on the rear of my car, to go along with the pair I have up front with 6/32 tread. The tread compounds are similar. Others on this board have mentioned that a discrepancy in rolling diameter might mess up the quattro system. Does anyone else have an opinion on this? Seems to me the difference is neglibible.

You're just asking for trouble.
I don't know why you would want to cut corners on a 30k car with "used" tires at all. It's the simple cost of car ownership and $125+ a piece for new correct size/spec tires isn't asking for much in my opinion.

it should be fine.. your overall diameter is still within 3% of eachother.
I have no idea where this magic 3% number came from tho...
however, the overall tire diameter is 25.4". 3% of that diameter so in theory you can have a difference of .75" in your tires?
.75 diameter diffence is a .375 radius difference. So you are allow 6/16s difference in tire tread.

Well, new tires would then have 12/32 tread (I think) which is a larger difference.
Or maybe it's not 12/32's, I'm not sure. But the front/rear discrepancy would be worse. Maybe that extra difference isn't a problem according to the guys above.
If it is, then I need to find tires with closer to 6/32's. Or buy a new set of four, which is a whole nother ballgame. Much more moolah. If you can even find P zero neros which are out of stock everywhere, at $150 a pop. plus, I hate trashing two perfectly good, though half worn, tires.
Hence my dilemna.

Do not mix brands or models.Dump the low tread ones & buy 2 new same ones to match w/the 10/32
Good tread in front. Only exception with mis-matched tires is if you take a PHYSICAL measurement of the diameter of both and if within 1-2% maybe ok. I would just get 2 new ones or better yet 4. Falken Ziex 512 is damn good and cheap at....<ul><li><a href="http://www.vulcantire.com">http://www.vulcantire.com</a</li></ul>
