AT tires, short for All-Terrain tires, differ significantly from regular tires, which generally refer to highway tires, also known as HT tires. The two types of tires serve different purposes, and choosing the wrong type could negatively impact your vehicle's performance.
AT Tires: Compared to HT tires, AT tires have a harder tread and more rugged patterns. These changes reduce comfort and fuel efficiency on paved roads but offer better grip and resistance to wear on unpaved surfaces. This is why they are called All-Terrain tires. AT tires are now commonly used on modified SUVs for improved off-road capabilities.
HT Tires: HT tires are designed primarily for highway driving, characterized by softer sidewalls and finer tread patterns. They generate less noise and provide excellent grip on paved roads. However, due to the softer tread, they are not suitable for intense off-road driving, and the finer patterns do not efficiently expel mud, which compromises grip in off-road conditions.
HT tires strike a balance between fuel efficiency and comfort while still offering some light off-road capability, making them a preferred choice for many manufacturers as original equipment tires.
There is generally no need for regular passenger cars to use AT tires. While some cars can handle off-road driving, such as those used in rally races, the typical usage scenarios for most consumers do not justify the need for AT tires. Using them can lead to increased fuel consumption, more noise, and reduced comfort.
