Hercules Strong Guard R1 Tires

Product Info

Strong Guard R1

The Hercules Strong Guard R1 tires are a specialty work tire for low-speed, field-focused applications where a wide footprint and dependable load support matter most. For shoppers at Advantage Tire Pros, this model is a practical option when you need an R1-style tire for agricultural or utility use rather than everyday highway driving.

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, supporting stable ground contact and soft-ground traction in work settings.

Because this is a specialty tire with a single active size, it’s important to confirm wheel fit, clearance, and intended application before ordering. If you’re comparing options or planning a service visit, Advantage Tire Pros can help you review the right setup and next steps.
