I recently ordered a Mercedes ML 320 Edition 10. This special edition comes with 265/45 R20 tyres , that seems excessive for a car like this.

I´m considering the possibility to change at no extra cost for a more reasonable 255/55 R18 or even 265/50 R 19. Normally 80% of the time I drive in dry situation but every year I use to go to skiing , and I think these kind of tyres are not good for snow or wet situation.

I would like to have your advice.

Thanks
