Hercules Strong Guard R1 Tires

Product Info

Strong Guard R1

The Hercules Strong Guard R1 tires are a specialty work tire for shoppers who need a wide flotation footprint and dependable load support in low-speed applications. At Lisac's Tire, this model is a practical fit for field, farm, and utility use where soft-ground traction matters more than highway comfort.

This catalog listing includes one verified fitment: 31x15.50-15, rated 121B with Load Range E and a 59 psi maximum inflation pressure. The flotation LT construction is designed to help spread weight across a larger contact patch, which can support stable ground contact and pulling-focused work.

Because this is a single-size specialty tire, it’s a good idea to confirm wheel width, clearance, and intended use before ordering. If you’re comparing options or planning service, Lisac's Tire can help with Schedule Appointment, Tire Consultation, and Locations.
