Hello, I drive a Mazda 3 BN Stafenheck Sportsline, EZ 08/2017 (KM-Stand 32,000km, driving behaviour 80% city / 20% overland + highway, defensive/economic driving style). As summer tyres I still ride the first equipment (Michelin Pilot Sport 3, produced in KW51/2016). Less the time on winter tyres I have driven with these tires so far about 20,000km. With horror I found today that the tyres on the front axle unusually strong wear signs (flat porous) have – left even more massive than right and at different rotation positions of the tires. I knew this so far only from 10 years old tractor tyres:-) It shocked me particularly, because I neither massively braked nor accelerated with the vehicle; also I can exclude 99%, that I have driven by shards or the like. Can you give me an assessment, if necessary, to how far the “normal” is or what could be the cause? In my opinion, the The vehicle is only a few weeks out of the warranty – would it be worth it from your point of view to make an attempt to get in touch with the Mazda dealer and to ask for a warranty against the background of material defects? Thank you in advance & LG Stefan
