my Karoq had 15000 on the clock and 3 years in when I got told I needed new tyres, I took it as high as the UK CEO and it filtered down that this was acceptable

Hi all newbie to this forum, I have a 68plate Karoq with 15500 on the clock I had a tyre rotation at 2 years and 11000 due to wearing front tyres I have just been advised on the mot that I need 2 per tyres, At 15500 this seems like a lot of wear for little use, they are Michelin 215/50/18 has anyone...
