I have a ready lift leveling kit and mine rides great, feels like a cadillac. Others will say not to do a leveling kit. But when i did i made sure the stock torsion bolts were screwed back in the same length as when the stock keys were in. You can do whatever you like. As far as tires i had some terra grapplers on my z71 and they rode fine, they did wear a little quick. I would defiantly suggest investing in some michelin tires. I have the Michelin LTX A/T 2's They are more expensive but will last twice as long. They are excellent tires. They have an aggressive sidewall and slight aggressive tread but ride extremely smooth on the road.
