I HAVE A 2015 TAHOE WIH A 2.5 LEVELING KIT. CURRENTLY RUNNING 285/60/20 TIRES WITH NO ISSUES. I WANT TO UOGRADE THE RIMS BUT IM N0T SURE WHERE TO GO WITH THE OFFSET. I WANTED TO GO WITH A 0 OR A +1. ANY INPUT SOMEONECAN GIVE ME.
20x9.0 with a zero offset or even a -10 to +10 Should work fine. There are plenty of wheels out there to fit these trucks. Standard offsets work on stock and leveled trucks, meaning whatever they recommend for a standard height will also work fine with the level kit.
Just to give an example, I am running a 22x10.0 with a zero offset, mine is a bit aggressive, but I like the tires to poke out the fender just a bit with it being leveled. I have a 2.5 front level and 1" rear spacer.
