I am looking to upgrade my jeep tires and rims. I use my jeep mostly for short trips to work and for hunting. I do not do a lot of serious off roading. I have a stock jeep and was considering the 285/70/r17 tires mounted on 9 inch wide rims that have 4.7 inch backspacing. Is this a set up I can run without making other modifications to my jeep? Am I choosing the best rim width for these tires? Thanks
