Hey everyone! I'm new to the site and I'm looking forward to your input. I have an 08 Silverado Z71 black reg cab short bed. I just ordered the Readylift 2.5 leveling kit and will be installing soon. I will be getting new tires too and would like your input as to which ones and what size. I like the Terra Grapplers and Cooper Zeons. Also which size? 285/60/18 285/65/18 275/65/18?
