Why choose the Nitto Terra Grappler G3 in LT235/80R18?
All-weather all-terrain confidence: The Terra Grappler G3 pairs an advanced compound with a redesigned tread pattern for dry roads, wet pavement, gravel, dirt, light trails, and changing seasons.
3PMS-rated snow traction: The Three-Peak Mountain Snowflake rating helps certify this tire for severe winter-weather capability, making it a strong choice for drivers who need snow-ready all-terrain performance.
Built for light trucks, Jeeps, work pickups, vans, and utility SUVs: The 121S E1 rating supports heavy-duty trucks, towing, hauling, overland gear, and work-ready payloads.
Off-road grip with road comfort: Staggered and concaved shoulder blocks, deep sidewall lugs, and varied tread-block sizing help add loose-surface traction while minimizing road noise on daily drives.
Wet performance and tread life: Full-depth sipes and the new compound help improve wet grip compared with the Terra Grappler G2, while the dual sidewall design gives each build a choice of appearance. This LT or flotation size is backed by Nitto's 55,000-mile limited treadwear warranty.
