Hercules Strong Guard H-DO Tires

Product Info

Strong Guard H-DO

The Hercules Strong Guard H-DO tires are built for medium-duty drive-axle service where traction, load support, and casing value matter most. At Gunnell's Tire & Auto, this 19.5-inch commercial lineup is a practical option for regional, vocational, and delivery trucks that spend long hours under load and in stop-and-go conditions.

Catalog fitments are limited to LT commercial sizes, with 225/70-19.5 and 245/70-19.5 available in the lineup. Load ranges G and H are represented, and the listed fitments carry an N speed rating. One 225/70-19.5 option is snow-rated and Three-Peak Mountain Snowflake-marked, giving fleets a winter-ready choice when cold-weather traction is a priority.

Hercules positions the Strong Guard H-DO with an open-shoulder drive tread, Gen-H tread compound, 3D sipes, and a tread-and-sidewall design aimed at helping resist cuts, abrasions, and stone retention in high-scrub service. If you’re comparing commercial tire options, Gunnell's Tire & Auto can help you match the right load range and size for your work truck.
