Product Info

Strong Guard H-DO

The Hercules Strong Guard H-DO tires are a commercial drive-position option for medium-duty trucks that need traction, load support, and durability in regional and vocational service. At Gunnell's Tire & Service Center, this 19.5-inch LT lineup is a practical match for work trucks that spend long hours under load and on high-contact routes.

Catalog fitments are limited to 225/70-19.5, 225/70-19.5, 245/70-19.5, and 245/70-19.5, with load ranges G and H and an N speed rating. One 225/70-19.5 option is snow-rated and Three-Peak Mountain Snowflake-marked in the current catalog, which can be helpful for fleets operating in colder weather.

Hercules positions the Strong Guard H-DO as a regional drive tire with an open-shoulder tread design, Gen-H tread compound, 3D sipes, and a wider tread footprint for demanding service. If you’re comparing commercial options or planning service around these tires, Gunnell's Tire & Service Center can help you choose the right size and load range for the job.
