Default Can I put staggered rims/tires on Quattro?

I am looking at the following set:
- front 18 x 8.0, 225/40/18
- rear 18 x 9.5, 265/35/18
Since I have AWD, I am fully aware that the front and rear tire circumference have to be identical. But it has been too long since a professor made me apply the formulas and I am looking for some help from forum members.
Does this setup make any sense at all? Tips, hints, etc. are greatly appreciated.

Default You'll need a tire size calculator...>>

But willl be better off with specific manufacturers specs as they vary even in identical sizes. Search google for tire calculators...There's a zillion out there...

Default usually 235/40's match up best with 265/35's :-)

here's a useful reference...
most manufacturers are represented on this Tire Rack chart:

*pick and click your tire
*click on "specs"
*select your proposed size(s)
*go accross the chart to find "diameter"

for example: Bridgestone Potenza SO-3's

225/40-18 diameter = 25.0 inches
235/40-18__________25.4
255/35-18__________25.0
265/35-18__________25.4

So:
225/40-18 works best with 255/35-18
235/40-18 works best with 265/35-18<ul><li><a href="http://www.tirerack.com/a.jsp?a=AR4&amp;url=%2Ftires%2Fsurveyresults%2Fsur veydisplay.jsp%3Ftype%3DMP">Tire Rack tech page:</a></li></ul>

Default Tire rack just told me yesterday that Audi only supports

the following:

225.45.17
225.40.18
235.35.19

He said anything else will throw off the speedo, which will throw off everything from the timing to the fuel injection, to yada yada yada, on and on.

Was I told incorrectly?

His name was Doug at extension 388

If going custom multipiece wheels, you could have the offsets varied instead, for a staggered look
