I sold those pieces of shite and got some 305/55/20 BFG ATKO. They are much larger and require a leveling kit though.
On a stock truck 275/60/20 Cooper LTZs look great. They are aggressive and last a long time. Slightly larger than stock but not huge.
ETA: The do make a 285/55/20 BFG ATKO but they are $$$
