how bad is this

[zimzima05]

is it bad to have my 16" stockers up front and my 17" aftermarkets in the back for a while till i get some new rubber on my 16" rears?

Yes.

as long as the rolling diameter is the same, you should be fine. Aside from the fashion faux pas...

i have a set of the oem 16" sport wheels and another set of 17" flik justice wheels.. two of my stockers are bald, and the other two are pretty much new. i want to put the stock wheels on my car and just have my fliks on there until i can get some more rubber.. we're supposed to have snow up here this weekend and there's not too much tread left on my fliks (but its still more than my bald stockers).

Diameter would be the initial concern, as Audi allows for just 0.3" differences between tires (quattro) before the differentials are affected
