Hi all, new here but looking to see if my A4 45 tfsi saloon is wearing its tyres normally. Had it a year, all 4 had 5 mm tread on falken tyres. I’ve now noticed the rears are on the wear indicator and the out side edge on both rears are smooth. Anyone had this or am I looking at alignment a bushes. Also could I just change the rear ones as the front are still good for a while. Any help appreciated 👍🏻
