A tri-axle vehicle has three axles, while a quad-axle vehicle has four axles. Typically, the axles are distributed evenly along the length of the vehicle, with one axle at the front and two or three at the rear.
Tri-axle vehicles are often used for heavy-duty applications, such as transporting large loads or hauling trailers. Quad-axle vehicles are also used for heavy-duty applications, but they can also be used for other purposes, such as passenger transportation or military use.
The main difference between a tri-axle and a quad-axle vehicle is the number of axles. This can affect the vehicle's weight distribution, handling, and maneuverability. Tri-axle vehicles are generally more stable and have a better weight distribution than quad-axle vehicles, but they are also less maneuverable. Quad-axle vehicles are more maneuverable, but they can be more difficult to control at high speeds.
Overall, the choice between a tri-axle and a quad-axle vehicle depends on the specific application and the desired performance characteristics.
