I'm 20 years old and I bought a 2000 jeep wrangler sport last year. I have been saving up to buy some tires and rims. I have 30x9.5 tires right now but I would like to move up to 31x10.5 tires with 3 inch backspace. Will I have any problems such as rubbing if I do this? I am also thinking about getting steel rims. I will not be doing any off-roading. Please give me some advice.
