All-terrain vehicle tires also known as ATV tires in common language are tires distinctively designed to meet all kinds of off-road conditions like muddy and hilly terrains. They are made for ATVs that are four-wheelers and for Sports Utility Vehicles (SUVs). These tires are used in vehicles for maximum road grip in these kinds of terrains.
The tires have been made to fulfill a number of problems including mud, sand and snow. The ATV tires are an advanced solution to better grip which general purpose tires are unable to provide. They have a large, chunky design. Their wide profile allows them to perform well in off-road conditions.
The ATV tires are of two types; ATV mud tires and ATV snow tires. ATV mud tires have large irregular-treads with wide gaps for maximum grip on all sorts of muddy conditions. The wide flat gaps between the treads enable the tire to sink into the top most layer of the surface for a better grip. The tires also aid to the stability of the car by giving the car more traction.
The most obvious characteristic of the mud tires is their large tread pattern. The tread on the tire is altered in a caterpillar track design that does not allow the tire to loose grip on the ground. The design of the treads is carved in straight or jagged lines which penetrate the ground by several millimeters. On a mud tire, these treads are much deeper than standard tires. This allows them to hold more mud for a firm grip. The pig chunky pattern easily digs into the mud and clears away quickly and easily allowing more mud to go in them.
The mud tires are common to all four wheel drive trucks and other specialized vehicles e.g. buggies, carts etc. Racing and off road vehicles are also fitted with them. They are a standard option in military vehicles. Due to their large size, they cannot be fitted on standard sedan-sized cars because of the limited tire space.
Mud flaps are must for mud tires. They are flexible pieces of plastic or rubber that are fitted behind the tires. They stop the mud coming from the tires, keeping the rest of the car neat and clean including the inside of the wheels.
There are a couple of negative aspects as well. Their blocky structure, does not allow them to perform well on regular flat or dry roads. Plus they do not give the amount of balance and stability which is required when driving fast on stable roads because of the big gaps in their treads. Another disadvantage is that because of the less tire surface which touches the ground, they deliver less traction. At times they can be very noisy as they have irregular treads hitting the road with air whistling through them.
