The Lexus LX IV (J300) is a full-size SUV with dimensions of 5100 mm in length and 1990 mm in width, which translates to about 200.8 inches long and 78.3 inches wide. Standard residential garages typically measure around 6 meters (20 feet) deep and 3 meters (10 feet) wide, which can generally accommodate vehicles of this size but may require careful maneuvering. The LX IV's width and height (1885 mm or 74.2 inches) can fit under most standard garage doors, but it could be tight for smaller garages or garage spaces with limited turning room.

The Lexus LX IV (J300) boasts a ride height and ground clearance of 200 mm (7.9 inches), which is quite favorable for a luxury full-size SUV. This clearance allows the vehicle to navigate rough terrains, shallow water crossings, and uneven surfaces without the undercarriage being compromised. Combined with Lexus’s advanced suspension system and off-road technologies, this height ensures the LX IV can perform proficiently in diverse environments while maintaining ride comfort on paved roads.

The Lexus LX IV (J300) comes equipped with various rim sizes including 18, 20, and 22 inches to suit different driving preferences and conditions. Tire sizes available include 265/65 R18, 265/70 R18, 265/55 R20, and 265/50 R22. Larger rims and lower-profile tires tend to improve on-road handling and aesthetics, while smaller rims with higher-profile tires enhance off-road capability and ride comfort. This variety allows buyers to customize the vehicle for better performance either on highways or rugged trails.

Compared to its predecessor, the Lexus LX III (J200), the LX IV (J300) maintains a similarly large and commanding presence but has subtle differences in dimensions and weight attributable to design enhancements and added technology.

Weight-wise, the J300 ranges from 2525 to 2780 kg, generally similar or slightly heavier due to added luxury features and safety equipment. Overall, the J300 builds upon the legacy of the J200 by balancing traditional ruggedness with modern refinement.

When compared with other full-size luxury SUVs such as the Mercedes-Benz GLS, BMW X7, or Range Rover, the Lexus LX IV (J300) stands out for its traditional robust and boxy styling, slightly longer length at 5100 mm (200.8 inches), and slightly wider stance at 1990 mm (78.3 inches). The LX IV offers competitive cargo space and a higher ground clearance than many rivals, emphasizing off-road prowess in addition to luxury. However, some competitors may offer marginally more refined on-road dynamics or interior technology, positioning the LX IV as a strong choice for buyers seeking a blend of rugged capability and premium features.
