The Dunlop Grandtrek AT23 is an all-terrain (A/T), all-season, all-weather tire. Standard-load (SL) construction.
Daily drivers who also run gravel, dirt, and the occasional trail need a tire that balances quiet pavement manners with real off-road grip. The Dunlop Grandtrek AT23 in 265/55-19 is a all-terrain option built for confident, real-world performance.
With a load index of 109 and load range sl, it supports the payload demands of full-size trucks and SUVs while maintaining a V-speed rating for everyday highway use.
Open tread voids clear dirt and loose debris while a stable center rib keeps highway tracking predictable. Commonly chosen by owners running mixed pavement, gravel, light off-road, and towing, the Grandtrek AT23 bridges the gap between capability and comfort.
Load range sl and a maximum load capacity of 2271 lbs lbs make it suitable for full-size trucks and SUVs carrying gear, equipment, or cargo without frequent pressure adjustments.
