Hi, I am new to this and need some help and advice. I use my ML off road alot in connection with my work. I am running on 275/55/17 UHP Grabbers about the best tyres I have found for grip in this size. Today I was told by someone that they have seen 265/70/17 on an ML the same year(2000) That would be grate for me I could then use BF Goodrich. Otherwise I will have to source a set of 16" wheels and then fit BF Goodrich. Can anybody HELP?
