Hercules Strong Guard R1 Tires

Product Info

Strong Guard R1

The Hercules Strong Guard R1 tires are a specialty work tire for soft-ground traction and dependable load support in low-speed agricultural or utility applications. At Gunnell's Tire & Auto, this model is a practical option when you need an R1-style tread built for field use rather than everyday highway driving.

This catalog currently shows one verified fitment: 31x15.50-15, rated 121B with Load Range E and a 59 psi maximum inflation pressure. The flotation LT construction helps spread weight across a wider contact patch, which can be useful when stable ground contact and pulling-focused performance matter most.

If you’re comparing specialty work tires, start with the approved size and confirm wheel width, clearance, and application requirements before purchase. Gunnell's Tire & Auto can help you review the fitment details and schedule next steps with confidence.
