I am getting ready to replace my 265/70/R17's on my 04 Suburban. I am considering the Michelin LTX MS2. I live in the Seattle area and use it primarily for hauling kids to school etc. We snow ski, and I tow a 18' boat in the summer. I see they sell a load range "E" but I don't know if this suits my application. Also, is there another tire I should be considering? I appreciate your thoughts and suggestions.
