Hello, I have a Jeep Grand Cherokee WH and would like to make some modifications in order to achieve a corresponding terrain suitability. I am also looking for appropriate accessories that fit here. It doesn’t seem to be much available at the MARKET. Who has already made some modifications here? Everything should be suitable for the strict Swiss MFK. Please report – Thank you Harry primary problem tires 245/65R17 – I don’t find any terrain meetings at all for the dimension – who knows more….
