Mine are at 30k with a lot of tread left, and you need earplugs now to avoid hearing damage due to the noise from the Firestone Firehawks. I am going next weekend (gotta work this weekend) to see what the local shop can order up for me. This is ridiculous. On the 30k note, ALL of my interior panels it seems started rattling all at once now. Dash, both doors, and I even got a metallic squeak from somewhere in addition to the squeaky front seats (TSB for this though).
edit: Quieter engine? How are they gonna do that? Sound deadening? Hopefully no engine redesigns just yet. Give me the Euro spec 2.0L TDI/CRD and I'd be set!!!
