Goodyear efficientgrip tyres

I went to Tyre Mart, 9 Padstow Street, Raceview, Alberton on Tuesday 30 November 2021 to fit two goodyear efficientgrip 225/45R17 tyres. I was helped by Mr Costa. When I arrived home I noticed that the treads and printing on the tyres are not the same as the one I googled. I went back to Mr Costa the following day 01 December 2021 to find out why the branding is not the same. He said goodyear has new technology on their tyres. Please can hellopeter help me in this regard, because I feel that this is not the truth. From Mooki Lephalo. Vosloorus. NB: I do have photos of the new tyres fitted
