2. 70 This number indicates the aspect ratio of the tire, expressed as a percentage. In this case, the aspect ratio of 70 means the height of the tire's sidewall is 70% of its width. So, for a 215 mm wide tire, the sidewall height would be approximately 150.5 mm (calculated as 215 mm * 0.70). A higher aspect ratio often corresponds to a more comfortable ride, as the taller sidewall can absorb bumps and imperfections in the road more effectively.

Manufacturers often employ advanced engineering techniques, including finite element analysis (FEA), to optimize the design of chassis side members. This analysis allows engineers to simulate crash scenarios and assess how the side members perform under duress. Innovations such as crumple zones are strategically integrated into the chassis structure, allowing for controlled deformation during an impact, further enhancing occupant safety.
