The LT275/70R18 Terra Grappler G3 brings a 125/122S Load Range E specification to Nitto’s snow-rated all-terrain design. It measures 33.19 inches tall, with full-depth sipes and staggered shoulder blocks. Use the LT size and measured dimensions for fitment, rather than treating its convenient flotation-size equivalent as a different tire.
Exact version: LT275/70R18 125/122S Load Range E; Nitto part 223970. Nitto lists 33.19 inches of overall diameter, 10.98 inches of inflated width and a 7.0–9.0-inch approved wheel-width range.
The G3 uses full-depth sipes, reinforced tread-block foundations and staggered shoulder blocks. Its Three-Peak Mountain Snowflake marking identifies its rated snow-traction capability; it does not guarantee grip in every winter condition.
