General Features Of Highway Terrain Tires

#1.Tread Void

Tread void is an essential part of the design of your tire. It refers to the space between the tread blocks of your tire, which gives the tire flexibility and adjusts to various road conditions. Moreover, it helps in preventing aquaplaning or hydroplaning.

Hydroplaning of your vehicle tires occurs when a layer of water starts building between the wheels and road surface. Consequently, your tire loses traction on the road. Fortunately, highway terrain tires have less tread void, enabling the tire to have good traction on a dry road.

#2. Tread Blocks

Tread blocks are the raised portion of the tire that comes in contact with the road surface. The highway terrain tires have tread blocks of various sizes that help in reducing noise.

#3. Grooves

The grooves are channels that run circumferentially around the tire. Highway terrain tires have circumferential grooves that help reduce noise when coming in contact with the road.

#4. Tire Shoulder

The shoulder is the area on the tire where the tread and sidewalls of attire meet. The highway terrain tires have semi-closed shoulders on the tire, which enable them to run quietly on roads.



Benefits Of Using Highway Terrain Tires

#1. H/T Tires Are Durable

Heat is usually generated when a tire runs on the road. The highway terrain has a special tread pattern that will enable it to reduce noise and liberate the maximum amount of heat. Consequently, it helps in enhancing the life of the tire.

#2. Good Traction On Wet Roads

Some models of highway terrain tires have waved pattern grooves that help channel water. Consequently, they increase traction on a wet road and reduce hydroplaning. So, if you usually drive vehicles on both wet and dry roads, I suggest you purchase highway terrain tires.

#3. Maximizes Fuel Economy

Highway terrain tires are designed to provide you with a smooth and comfortable ride. Moreover, it also accelerates fuel economy. Fuel economy means the number of miles your vehicle can travel by using a precise amount of fuel.

Highway terrain tires will enable your vehicle to travel much more miles in a set amount of fuel which is rarely seen in other tires. It is an excellent advantage for trucks and SUVs that usually travel with less mpg(miles per gallon)

#4. Good Braking And Cornering

The tread design on the tires is less aggressive, which provides good braking and cornering, which is hardly seen in other tires.
