Hercules Strong Guard H-DO Tires

Product Info

Strong Guard H-DO

The Hercules Strong Guard H-DO tires are built for commercial drive-position use where traction, load support, and casing value matter. At Gateway Tire & Service Center, this 19.5-inch LT lineup is a practical option for medium-duty trucks and vocational fleets that spend long days in regional, delivery, and high-contact service.

Catalog fitments are limited to 225/70-19.5 and 245/70-19.5 sizes, 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 active catalog, which can be a helpful choice for fleets that work through colder conditions.

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 aimed at traction and wear support. If you need help comparing fitments or planning service, Gateway Tire & Service Center can help you shop the available options and schedule your next visit.
