I am planning on putting a 3.5-4.0 inch lift on my 15 JKU. I would like to run 35s on this when the lift is complete. I would like to use my factory wheels if possible, but I am not sure if i can after reading some threads that stated i would need spacers. So assume a 3.5 lift and 35s with factory wheels? Would it work or no? Also, if the answer is no, how do i know what size spacing i would need from the aftermarket rims that i order? Thanks in advance.
