Tagging onto this I have a question. James0808 - What pressure did you use with the originals, I assume 205/55 R16? I've noticed on the dor pillar that Audi's conversions from BAR to psi are odd. 2.2 bar = 34 psi, 2.3 bar = 34 psi. On a Cabriolet I've seen 2.3 converted to 33psi. Inconsistant by Audi. I'm not sure what to use, could be anything from 32psi to 35psi from what I have read. Any thoughts?
