    Default 2010 Sierra All Terrain tire options...

    I own a 2010 Sierra All Terrain.

    Im wondering what my options are on tire sizes that will fit without altering any other part of the truck (suspension, body, etc).

    The stock tire size is 265/65-18 and there are not too many options in that size for a decent A/T or more aggressive off road tire. Could I run a 275/65-18 or a 285/60-18 without any issues?

    I would guess no larger than a 32" tire, but that still may be cutting it close without a leveling kit. I pasted below a tire calculator in case you receive any other feedback, as it will help you convert tires sizes to diameter inches easily.
