Kenda Super Turf K500 Radial Tire 20/10.50-8

What It Is

The Kenda Super Turf K500 Radial Tire (20/10.50-8) is a heavy-duty, radial-ply turf tire designed for zero-turn mowers, large lawn tractors, and commercial mowing equipment. It provides low ground pressure and a smooth ride on turf, while handling heavier loads than standard bias-ply tires.

Fitment & Compatibility

• Size: 20/10.50-8 (20-inch overall diameter, 10.50-inch section width, 8-inch rim). Verify your current tire’s sidewall markings match exactly—slight variations in width or diameter can affect clearance.
• Rim: Fits an 8-inch diameter wheel. Check your rim width (typically 7-8.5 inches) and bolt pattern (commonly 4×4 or 5×4.5 inches). Measure center hole size and offset if using aftermarket wheels.
• Machines: Common on commercial zero-turns (e.g., Gravely, Scag, John Deere, Toro, Exmark) and large lawn tractors. Not for push mowers or small residential riders.
• Load & Ply: Rated for up to 1,545 lbs per tire (at 30 psi). Ensure your mower’s weight (including operator and attachments) doesn’t exceed this per tire.
• OEM vs Aftermarket: Fits many OEM applications but always cross-reference with your machine’s parts diagram or call the manufacturer for confirmation.

Key Things to Know

• Radial vs Bias: Radial construction offers better traction, less vibration, and longer tread life than bias-ply tires, but requires proper inflation (check sidewall for recommended PSI).
• Installation: Mounting on a narrow rim can be tight—use tire lube and a bead sealer. Balancing may be needed for high-speed mowers.
• Tread Pattern: The K500 has a shallow, chevron-style tread for minimal turf damage. Not for mud or soft ground—it will spin easily.
• Price vs Value: At ~$69, it’s mid-range. Cheaper bias tires exist, but for commercial use or heavy machines, the radial upgrade is worth the extra cost.

Should You Buy It

If you own a heavy zero-turn or large lawn tractor and want a tire that reduces turf damage, rides smoother, and lasts longer than budget bias-ply options, the Kenda K500 is a solid choice. It’s not ideal for muddy conditions or light-duty residential mowers, but for commercial or heavy residential use, it delivers excellent value.
