Hercules Strong Guard R1 Tires

Product Info

Strong Guard R1

The Hercules Strong Guard R1 tires are a specialty work tire for low-speed agricultural and utility use, built around a wide footprint and dependable load support. At Ron Gordon’s Tire Pros, this model is a practical choice when soft-ground traction and stable ground contact matter 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. That flotation LT size is designed to help spread weight across a larger contact patch, which can be useful for pulling-focused work and field applications.

Because the active catalog shows only this one size, it’s important to confirm wheel width, clearance, and intended use before ordering. If you’re comparing specialty work tires or planning a replacement, Ron Gordon’s Tire Pros can help you review the fitment and next steps.
