Rear tyres

Bought 2020 DS7 CROSSBACK E-TENSE with 9500 miles in March '22 by May after 3000 miles returned to dealership as rear tyres were VERY worn,DS replaced at their cist there and then. Now 6000 miles later the new tyres the pur on are totally worn and need replacing immediately. Tyres are 235/45 r20 100v. I’ve ever had tyres go so quickly, is there any recognised issue with the DS7 that could be causing this please?

It’s a common issue with the E-Tenses, the dealership should replace the tyres if they are unusable before 20k - they also had a safety recall some months ago where they replaced all e-tense rear tyres with 235/50. I’m not sure what the issue was, but it seems that you don’t have those tyres fitted.

Best bet is to call DS and ask them to look for any TSBs (Technical Service Bulletins) related to the alloys and tyres for your vehicle.

However, it should be pointed out that hybrid 4x4 tyres will wear out quicker, as the regen and weight of the hybrid will put additional stress on the tyres.

Do you have details of the technical bulletin in relation to the tyres please? I have just checked and we have 235/45s on the rear of our 2020 DS7 E-tense.
