I need help here from the forum. I recently had a rear blowout in my 98 Audi A4 2.8 Quattro. I had a nail that punctured the inner sidewall, so a new tire is needed. Will having one new tire on the car affect the quattro system? With having more tread on the tire?

Tire rack and most other suppliers will shave a tire down to match tread depth however.

If you run a different tire or a tire with more then 2/32nds difference *Audi says* it's bad for the differetial...

What kind/size of tire? maybe someone has one that would work for you?

Unless they are close I think you might need to get a new set.

If the tire sizes are different than the Torsen system is constantly under stress. This can lead to early failure of the AWD system(s).

I have roughly 15k on the set of tires right now, they ar 205/55R16

how much tread is left on the other 3 tires?

johnnydub11

There is a lot of tread left, still has the little nipples for the most part, about 15k on the tires.

If you have 6/10ths left you are fine.

Not sure if it'll be compatible with the limited info posted here, though.

my tires are almost always nearly bald after 15K. (maybe they take after me ;-) )

Anyway, take a penny, stick it in the tread so Abe's head is into the grove, snap a pic for us. using that as a reference we (collectively) can estimate how much tread you have left. then when you get a new one either buy used with similar tread depth, or have a new one shaved to the same depth.
