I have been looking online googling and trying a search on this forum and can't find the answers that I am looking for. I am going to get some torsion keys and some new wheels and tires for my 2003 crew cab duramax, but I am kind of hung up on what size tires I can run and also what wheel I need to get.I want to get just about the biggest tire I can under it with just the leveling kit. Any suggestions on which offset, back spacing, and hub bore I would need?Also how big of tires can I run with just a leveling kit? I'm hoping to get some information from some of you that have this size of wheels on your trucks. Or anyone who works at a tire shop and can help me out. Thanks in advance for the help guys. Take care. PS any pictures are appreciated as well.
