Features and Benefits

The Gladiator QR77-DL Drive Lug, as the name indicates, is a drive axle or torque axle position tire, which means this commercial tire is made for the front axles of trucks (not the steering axles) where they perform as the traction generators or act as workhorses. These truck tires usually get a lug-type or sipe tread design and are optimized for improved traction performance on different surfaces. Now, let’s look at the QR77-DL Drive Lug features and their corresponding benefits to learn about the tire’s capabilities.

• Improved traction performance – The QR77-DL Drive Lug features an open shoulder tread design that improves traction in dry, wet, and light snow conditions. The tread of this tire sports detailed siping across the profile that increases traction and grip in wet and light snow conditions. The zigzag grooves further improve the tire’s ability to perform in slick and slippery conditions by dispersing water from the footprint and preventing the tire from the risk of hydroplaning.
• Longer service life – The flat footprint of this tire features uniquely arranged tread blocks that prevent the tire from premature or irregular wear and offer extended usability. The solid compound and construction also extend the tire’s service life by holding the shape when the loads are higher.
• Solid durability and increased load-carrying capacity – The tire is also optimized for solid durability and increased load-carrying capacity. It gets a reinforced steel-belt radial construction that compliments the sturdy rubber compound and robust sidewalls to prevent the chances of cuts and chips and withstand increased loads.
• High-speed stability – The design and construction of the QR77-DL is such that it maintains surefootedness while the truck is running on the highways at high speeds. The flat contact patch keeps the tire stable whether it is rolling in a straight line on the highways or while taking turns.
• Low rolling resistance – The compound and construction of the QR77-DL Drive Lug are engineered to reduce the rolling resistance to allow free movement without any lag during regional service. The low rolling resistance also contributes to improving fuel efficiency, thus allowing you to cover more miles and reduce operating costs.
• Low noise generation – The tread arrangement of the QR77-DL Drive Lug is such that it controls the tread noises.
• Optimum self-cleaning – The open shoulder tread design of this tire promotes self-cleaning for increased contact with the surface and better traction and grip in varied conditions.
