    I will be in need of a set of new tires this fall for my '11 GMC 2500HD crew cab. Wondering what the biggest size is that will fit stock on the OE 20" wheels? The stock tire size is what I have on now which is a 265/60R20 10 ply Goodyear sissy tire. Looking at either putting on a 275/60R20 BFG All Terrain 8 ply or 275/65R20 10 ply in either a BFG or Dick Cepek Fun Country. Wondering what size other guys are running just to see if the bigger size 275/65R20 will rub or not without modification. I will have a Boss 8' straight blade on it.
    Any input if appreciated!

    Those Cepek Fun Countrys have some great tread life.
