After searching I still have a question on tire sizes. On a 09 JK with 17 inch stock aluminum rims / it appears to be a 31 in tire, can I go to 32 on the same rim or will something else be affected? Also can I go with the same 31 and just a wider tire? What sizes will work in place of my 255/75/17 s. I m just looking for a little beefier looking tire the simplest way. 85% driving on roads and tons of winter snow. Anyone have pics of a 285/70/17 on their Jeep?
