What Does RT Stand for in Off-Road Tires?
2 Answers
Off-road tires do not have an RT model; they only come in AT, HT, and MT. Below is a detailed introduction to the tire models: 1. HT Tires: Most vehicles driven in urban areas use HT tires. HT tires are designed for highways, with denser tread patterns and relatively softer sidewalls, providing a more comfortable ride for passengers on smooth roads. 2. AT Tires: AT tires, known as all-terrain tires, are designed for vehicles with some off-road capability and are suitable for all road surfaces. The tread gaps are larger than those of HT tires, and they wear out faster. 3. MT Tires: MT tires are mud-terrain tires, specifically designed for off-road use with very strong grip. They can quickly expel mud from the tread gaps when driving on muddy terrain, making it easy to handle mountain and muddy roads. They are typically installed on off-road vehicles.
I've been driving off-road vehicles for years, and the 'RT' on tires stands for Radial Tire, meaning radial ply tires. The structure of this type of tire features cord plies arranged radially from the center, unlike the crisscross pattern of old bias-ply tires. On off-road trails, what impresses me the most is its super-strong sidewalls, excellent cushioning over bumps, stable grip, and resistance to cuts or deformation. For example, when driving in the desert where the terrain is full of hard sand and stones, RT tires hold up well, and they also offer better fuel efficiency and longer lifespan. Nowadays, most new tires are marked with RT. When purchasing, look for the tire code like 265/70R17, where the 'R' stands for radial. I recommend off-road enthusiasts not to skimp on this—RT tires can enhance both the fun and safety of off-roading. Maintenance is also simple: regularly check tire pressure and tread patterns, and avoid damage from high-temperature roads.
