Which is better for mud?

Both are mud-terrains. The KM3 claims 5% better mud traction than its predecessor and adds Coregard Max sidewalls. The Trail Grappler counters with 21/32-inch tread depth. For deep mud, the deeper tread helps; for sidewall damage on rocks, the KM3 has the edge.

Is the Nitto worth the extra $123?

Only if you need its specific size and load rating. The Trail Grappler lists 3,305 lbs max load and 21/32-inch tread. The KM3 costs less and covers more sizes, so most buyers get more tire per dollar from it.

Neither listing gives a treadwear rating. The KM3 carries a 6-year warranty, which is the only longevity signal here. The Trail Grappler's deeper 21/32-inch tread can last longer before replacement if rotated regularly.

Which is better for a daily-driven truck?

Both are loud, heavy mud tires. The KM3 comes in more sizes, so you can pick a narrower, lighter fitment. The Trail Grappler at 72.64 lbs per tire will cost more in fuel and ride comfort.

Do both come in 17-inch sizes?

The KM3 covers 17-inch wheels within its 55 sizes. The Trail Grappler listing shows a 17-inch LT285/70R17 E size and 20-inch options. Check the exact size you need at each store before ordering.

Which has better sidewall protection?

The KM3, on paper. Its Coregard Max sidewall technology is designed to resist cuts and punctures. The Trail Grappler listing shows no run-flat and no special sidewall armor.
