I ran 33x12.5 15's for years on may different trucks 8"s and 10"s. Any tire larger than stock will increase wear rate on many parts and cost you mpg.

33 on a 16" will look smaller than on a 15" because you are losing side wall height to gain rim size. Also 33x12.5 on a 10" wide rim will not have much sidewall bubble, and if you air down off road you will have a better chance of losing a bead or wheel lip damage. 35" is when I would start to look at ratio's.

on your truck I would go 15x10 and 33x12.5's it would look nice. I think that 16" would be like a 305/65/16 on a 16x10, and they look skinny beside the 15x10's

just my 2c.
