Leveling 2015 Silverado LTZ

[Dad's72]

I have a 2015 Chevy Silverado LTZ and I would like to level it and put a little larger tires. I was wanting to see if any of y'all out there have a truck similar that are leveled and if so what tire size are you running?
I am thinking about the Rough Country Leveling Kit as it is super cheap and I have read pretty good reviews on it. I would be keeping the stock rims but would like a little taller tire to fill the wheel wells a little better and for a little better over all look.
Pics are always good. I would like to see the results of anyone out there with a similar leveling kit and larger tires.
Thanks.
