The Opel Astra J GTC features a ride height or ground clearance of 112 mm (4.4 inches). This relatively low ground clearance enhances the vehicle's aerodynamic profile and improves handling by lowering the center of gravity, which is beneficial for sporty driving and cornering stability. However, this ground clearance requires cautious driving over speed bumps and uneven surfaces to avoid potential undercarriage damage, making it more suited to smooth urban and highway roads rather than off-road conditions.

Correspondingly, the tire sizes available are 235/55 R17, 235/50 R18, and 235/45 R19. These sizes balance aesthetics with performance, providing good grip, ride comfort, and handling precision.
