Hello, I would be happy about your tips regarding the tyre change. I currently have the following tyres and am not sure if I should drive the one more summer. Audi A4 Avant TFSI 1.8 Summer tyres: Dunlop Sport 225-50-17-94-Y Profile depth front axle: 4mm and 3mm Profile depth rear axle: 7mm Dealer wrote something like tires no longer sufficiently on the storage slips. Colleagues however said 3mm is still enough for a summer. What do you think? I drive with it every day at work but there s is city traffic and about 20km back and forth. Thank you for your tips.
