Alright guys I have my leveling kit and my tires. I'm stumped on what wheel to get bc of the back spacing offset thing. The ones I wanted are the black rhino dunes. They are 17x9 with a -12mm offset 4.5 inch back spacing. The other wheel I looked at was a 17x8.5 with a 12mm offset 5.25 inch back spacing. Which wheel will work better and is there a better choice on back spacing I should look into

Thanks in advance for the help
