The EFX HAMMER is an all-terrain (A/T) tire.
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 EFX HAMMER in 23x9.50-12 is a all-terrain option built for confident, real-world performance.
With a load index of 70, it supports the payload demands of passenger cars and crossovers while maintaining a F-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 HAMMER bridges the gap between capability and comfort.
A maximum load capacity of 750 lbs lbs make it suitable for passenger cars and crossovers carrying gear, equipment, or cargo without frequent pressure adjustments.
