It has an ST code for it, and ST tires are not made for motor vehicles’ turning and stopping requirements, and it should never be used in anything but a trailer. Some tires have their casings, and they are explicitly made and embossed for specific uses only on mobile homes, off-highway, or farms. 

ST means special trailer. So if you want to, you can use trailer tires on your vehicle, but you should not. Trailer tires are made specifically for the rigors of trailering. 

They have sidewalls that are stiff to support high weight stress typical of trailer applications. The ride can be harsh in your vehicle, and the traction characteristics can be dangerous. A passenger vehicle and a light truck are made for accelerating, braking, and cornering.

They are different from the tread and the sidewalls to the ply and the structure. They are both tires, but their functions and duties will keep you on the road differently. A truck or a car’s tires are made to be on a lead vehicle. 

They have this thick tread because they will maintain traction on slippery roads and sharp turns. They are also made to handle high speeds of driving on the highway. A trailer tire is made to be on the following vehicle. 

They have thick sidewalls to handle debris and some other objects. The tread is also not as thick as the car tires. They are also not capable of maintaining traction. 

They are made specifically to accommodate the sway of a trailer. Driving above eighty miles per hour with a trailer is not recommended.

trailer wheels are made to have a zero offset so that there is even tread wear if they deal with a heavy load. Old vehicles are used for conventional steel wheels.
