This will be my first tire upgrade on my stock 2013 Rubicon Unlimited. The stock tires are wearing badly and are extremely loud when on the pavement. I have been following some threads, and am still confused about what will work. I'd like to move up to 33 in. tires and keep my stock wheels. I thought that the 285/70r 17 Duratecs were 33, however, one of the threads said that they were 32in. Will I need wheel spacers, and are they hard on components? Will they rub when the sway bars are released? And finally will I need a 2 or 2 1-2 lift and would you recommend the coil lift over the spacer lift and why? I know this is a lot of information, but I would like to make an informed decision based on feedback from those of you that have experience in this area. Any other tire recommendations would be appreciated.Thank you in advance for your reply.
