• The Audi A3 2.0 TDI 170 S-Line is a diesel engined car rated at 170PS of engine power. Putting that power on the tarmac is only possible if you have the right tires for the task, as they provide the contact patch between your vehicle and the ground. The best tires for the job are the ones recommended by Audi.
