Has anyone widened stock rims?

[RobFromNJ]

Hey everyone,

 

New here. I have a 2015 Silverado 5.3 LZ1 and I'm starting to price out my build. I've been planning a procharger, kooks long tubes, custom tune, leveling kit, and auto locker build for March/April with rims/tires and possibly a cam and valve springs to follow over the summer. I've been looking into aftermarket 20's to put 33s on, but after seeing a tahoe today with the same stock 20s that i have (below) with some aggressive looking ATs I'm looking to keep the stock wheels. But i want to run a 12.5" x 33" tire, and know that i'll need a 9.5" wide rim. Which leads to the question...

 

Has anyone widened their 2014/15 K2 rims, and will they fit without wheel spacers? Also, I don't need to run 33s, but i'd like to. I could go with a slightly smaller tire, but I definitely want to go 12.5" wide.

 

Any help is appreciated.

 

 

Thanks,

 

Rob
