The Nitto Terra Grappler promises good road manners with decent off-road ability, but critics have already found an all-terrain tire for light trucks and SUVs that fits that description -- the Cooper Discoverer A/T3 (Est. $170) -- and it carries a 55,000-mile tread-wear warranty. The Nitto has none.
Owner reviews are mixed. Some say the Nitto does a great job on winter roads, while others say it slides in the snow. None of our experts takes the Nitto off the pavement, but owners largely agree that the Terra Grappler handles moderate rocks and mud just fine. However, some owners doubt it could hold up in sharp rocks and deep mud. For heavy off-roading, critics prefer the Goodyear Wrangler MT/R with Kevlar (Est. $220) .
The off-road enthusiast magazine Petersen's 4Wheel & Off-Road tests the Terra Grappler, but only on-road. For off-road feedback, we turn to owner reviews at Offroaders.com and Epinions.com. The National Highway Traffic Safety Administration website publishes the Terra Grappler's official ratings for tread wear, traction and heat resistance.

The National Highway Traffic Safety Administration requires manufacturers to test their tires' tread wear, traction and heat resistance, and to label the tires with these ratings. The Nitto Terra Grappler earns a high wear rating for an all-terrain tire, with an A for traction (the highest rating is AA) and a B for heat resistance (the highest rating is A).
