I have a 2002 ext cab z71. I would like to put on 6 inch lift and 35 inch tires. I continue to hear you dont want to go larger than 35 inch tires on a half ton, and ideally no larger than 33's. Is the problem just the axles? Would getting beefier axles take care of the problem of the larger tires? Or are their additional concerns on the half ton vs the larger truck? Thanks.
