Next, the “70” represents the aspect ratio, which is the height of the tire’s sidewall expressed as a percentage of the tire's width. Therefore, a 70 aspect ratio indicates that the height of the sidewall is 70% of 245 mm. This ratio affects the tire's handling characteristics, ride comfort, and overall performance. A higher aspect ratio generally leads to a softer ride, as there is more rubber to absorb shocks from the road.

Modern chassis motors employ advanced technologies that significantly boost their performance and efficiency. Innovations such as rotor design, magnetic materials, and cooling systems enhance power output while minimizing energy losses. For instance, permanent magnet synchronous motors (PMSMs) are widely used in electric vehicles due to their high efficiency and compact size, making them ideal for chassis integration.
