Leao 221016662 R781 ST205/75R15 107/102M Load Range D 8-Ply Steel Belted Trailer Tire

The Leao R781 ST205/75R15 is a highway terrain, all-season steel-belted radial tire engineered exclusively for trailer applications. Manufactured by Leao Tire — a sub-brand of Shandong Linglong Tire Co., Ltd. — the R781 delivers reliable traction, structural stability, and fuel efficiency mile after mile. This tire is designed for trailer use only and must not be mounted on passenger cars, SUVs, or light trucks.

All-Weather Traction

The symmetric ribbed tread compound combined with an optimized tread block layout provides confident grip across dry, wet, and light winter road surfaces. Sipes throughout the tread pattern add additional biting edges to maintain traction as conditions change, while the all-season rubber compound preserves flexibility across a wide temperature range for consistent year-round performance.

Hydroplaning Resistance

Circumferential grooves channel water and slush away from the tire's contact patch, reducing the risk of hydroplaning on wet roads and helping maintain stability during towing.

Enhanced Controllability

The symmetric ribbed design maintains constant, even surface contact, which translates into improved steering response and tracking stability for the towing vehicle. This helps the trailer follow the tow vehicle's inputs precisely, reducing trailer sway and improving overall towing confidence.

Fuel-Efficient Performance

By optimizing all-weather traction, the R781 reduces rolling resistance — the energy required to keep the tires in motion — helping lower the towing vehicle's fuel consumption and CO2 emissions over the long haul.
