[V6-12v] New Wheels and tires combo

[Clive Young]

Hi Guys 

Project Audi  has hit the bricks for now ( litterally ) as my car is jacked up motionless for the winter. I looked a my 15" rims and "balloon tires" and wondered if you guys had any suggestions for improving looks. 

I am not sure of the size even when looking on the net , I have a 4 bolt pattern but some say 84mm some say 100mm, anyone know what this means ? or maybe even know what size a 95 90S would be ? 
 I thought of going to a 16  or maybe even a 17" rim and would appreciate comments.

As a side note i checked the registry to check some of the cars, some nice rims there, but I can not load a picture of my car for you all to see ( laugh at ! ) it is a 1M jpeg file but when I press the modify button I get a dead link ! anyone else have this prob ? 

All the best 
and happy motoring to you quatro guys .... grumble grumble. :-P
