Need tire size advice for my 2001 S4

[Racer Doc]

My S4 has a H&R suspension and RS4 replica Wheels with the following specs:

Diameter - 18"
Width - 8.5"
Offset - ET38
PCD - 5x112
Weight - 26.5lbs
Centerbore - 57.1mm
Lug Bolts - 14x1.5 27mm R13 Ball Seat

I am looking for an aggressive but would like to avoid tire rub for my daily driver.

Try a small spacer if your looking to save money on tires.
